Brain Scans Can Predict Music-Induced Emotions

In Finland at the University of Turku, researchers in the national PET Centre recently discovered neural mechanisms that arise as an emotional response to music. Subjects who participated in the study (102) listened to emotion-evoking music while undergoing functional magnetic resonance imaging (fMRI).

To map which brain regions are activated based on different music-inducing emotions, researchers created a machine-learning algorithm. Postdoctoral Researcher Vesa Putkinen said, “Based on the activation of the auditory and motor cortex, we were able to accurately predict whether the research subject was listening to happy or sad music. The auditory cortex process the acoustic elements of music, such as rhythm and melody.  Activation of the motor cortex, then again, may be related to the fact that music inspires feelings of movement in the listeners even when they are listening to music while holding still in an MRI machine.”

Specific brain regions are activated when humans watch videos that evoke strong emotions. This was better discerned by the researchers who tested whether the same areas were activated while listening to music that evokes emotions. The results indicate that emotions evoked by film and sounds are based on different brain synapses.

Real-life situations are mimicked in films, which activate the deeper parts of the brain that regulate emotions. These regions were not strongly activated while listening to music, nor did it separate the music-induced emotions from one another. Researchers hypothesize this difference stems from the fact that films are more realistic in portraying real-life events that evoke emotions and brain synapses; cultural influences and personal history impact music-induced emotions based on music’s acoustic characteristics.  

In the past, music-induced emotions have been studied through classical instrumental music. Putkinen stated, “We wanted to use only instrumental music in this study as well, so that lyrics did not impact the emotions of the research subjects. However, we included film music and songs by the guitar virtuoso Yngwie J. Malmsteen.”

MRI Providers: Watch for Patients with Metal Face Masks & Magnetic Eyelashes

Technologists are well-aware of the possibility of metal burns from MRI machines. Due to the components of an MRI, all metal must be removed prior to patients entering Zone III, the space before entering the scanner room. The COVID-19 pandemic has forced the world to wear face masks in public indoor areas, including medical procedures. Also, of recent fashion trends, women have become more prone to use magnetic eyelashes, a beauty product that is easier to apply and remove. Both have resulted in MRI patient injuries.

The U.S. Food and Drug Administration (FDA) released a statement warning health care providers that patients might be injured if they wear face masks with metal parts during a Magnetic Resonance Imaging (MRI) exam. These small metal parts are usually found within the nose area or throughout the mask fabric. Nose clips, wires, ultrafine particles, or antimicrobial coating (silver or copper) can become hot and burn MRI patients.

This note of caution comes as a patient received burns from donning a face mask during an MRI. “The FDA is reminding patients and providers that patients should not wear any metal during an MRI,” according to the statement issued.

The Journal of Applied Clinical Medical Physics issued a report explaining how magnetic eyelashes are unsafe in an MRI; some lashes can rapidly become moving projectiles. False eyelashes are placed onto magnetic eyeliner (applied to eyelids) or discreetly clamp around natural eyelashes. Patients might forget to mention the eyelashes and MRI technicians might not notice them.

All medical providers should screen patients for MRI safety. Tiny metallic objects within face masks or fake eyelashes can easily slide past an initial assessment. If patients experience burns while wearing face masks, providers are encouraged to report the incident to the FDA. Gathered reports help the FDA improve patient safety.

For more information regarding the FDA’s warning, read the full report. The complete journal article pertaining to magnetic eyelashes can be found here.

National Radiologic Week Celebrates Technologists

Few people and professions have been on the front lines of the COVID-19 pandemic as much as radiology technicians. They have directly impacted patients and taken a front-seat approach to the outbreak, as they work closely with coronavirus patients daily.

National Radiologic Technology Week (NRTW) marks the centennial celebration for the American Society of Radiologic Technologists (ASRT) but also serves as an opportunity to exhibit those who perform thousands of X-rays, MRIs, CTs, mammograms, nuclear medicine, cardiac and vascular international, and ultrasound procedures weekly. NRTW is celebrated annually to recognize the vital work of radiologic technologists across the nation. It commemorates the discovery of the x-ray by Wilhelm Conrad Röntgen on November 8, 1895.

Over 340,000 radiologic technologists have conducted chest X-rays, CT scans, and cardiac ultrasounds for COVID-19 patients. These lifesaving techniques have been critical in detecting and managing virus progression. Proper ventilation placement and ensuring patients receive appropriate care is of the utmost importance when dealing with pandemic patients.

To learn more about NRTW, check out the American Society of Radiologic Technologists website. For purchasing radiologic equipment, contact the experts at Acceletronics today.

Brain Tumor Visibility Doubled with New MRI Technique

When compared to existing visualization methods, a new 3D technique with MRI scans doubles the visibility of brain tumors. Since a large number of tumors are discernable, the new process has the potential to make it easier to treat them earlier and at smaller, more manageable stages.

Robert Edelman, M.D., is an inventor, lead author, and clinical professor of radiology. His work was shared in the Science Advances journal. He said, “Our goal is for the new technique – T1RESS – to help thousands of patients by allowing malignant tumors to be detected at an earlier, more curable stage.”

According to the American Brain Tumor Association, 700,000 Americans are living with brain tumors and 16,000 will die this year. The new MRI technique can catch the tiny malignant tumors that often escape notice, potentially saving lives and improving outcomes. 

The hope is that those patients undergoing surgery or radiotherapy will receive better clinical outcomes by making the tumor margins on contrast-enhanced scans more visible.

Edelman and his colleagues studied brain tumors in 54 patients to determine how well T1RESS works. He applied magnetic fields and radio waves used to generate MRI signals differently from existing imaging techniques. The new technique uniquely manipulates brain tissue signals to produce images that offer significantly improved tumor visibility. This application makes T1RESS highly sensitive to the T1 shortening effects of paramagnetic contrast agents, but it also reduces the signal intensity of non-enhancing background issues, both improve tumor visualization.

Experimental results showed that the new technique provided a two-fold improvement over existing MRI methods in regards to the contrast between tumors and normal brain tissue. Edelman compared the visualization to seeing more stars: “There just isn’t enough contrast between the stars and the sunlit sky to make them visible. In the case of brain tumors, T1RESS doubles the contrast between tumors and normal brain, so the tumors are more easily detected. It’s like looking at the stars on a dark night instead of a sunny day,” Edelman said. 

A larger, multi-site trial will need to be performed in order to confirm the findings, but the plan is to apply this technique to both prostate and breast cancers as well. If the benefits are confirmed, widespread use will be as simple as the installation of a specialized software package.

Radiologists Urge Use of Medical Imaging and AI-Powered Solutions to Manage COVID-19

Recent high-profile cases of COVID-19 combined with the effort to aid in the ongoing battle  against the pandemic have prompted RADLogics to deploy the company’s AI (Artificial Intelligence)-Powered medical image analysis solution worldwide. The company urged U.S. clinicians to embrace medical imaging and emerging technologies such as AI. RADLogics has an AI-powered solution in place which has processed and analyzed thousands of suspected coronavirus cases globally. These efforts have eased the surging workload for radiology, ER, and ICU teams worldwide.

RADLogics strives to make its CT and X-ray AI-powered technology available to hospitals and healthcare systems throughout the U.S. This technology will assist in COVID-19 patient triage and management by providing quantitative analysis to clinical teams. Those patients who exhibit severe or worsening respiratory conditions are accurately assessed, allowing doctors to better triage patients based on those who urgently need intensive care such as ventilator support.

Moshe Becker, CEO and Co-Founder of RADLogics, said, “The use of CT and X-ray in the assessment and treatment plan for President Trump underscores the critical role that medical imaging must play in the fight against COVID-19. We must scale the capabilities of these medical imaging procedures rapidly to support clinicians, hospitals, and healthcare systems throughout the U.S. as they respond to the anticipated second wave of coronavirus and the roll-out of a potential vaccine. Now is the time for hospitals and healthcare providers to embrace and leverage the power of AI technologies and solutions to not only alleviate the increased burden associated with COVID-19 but to help support better outcomes by reducing burnout and errors while delivering better patient outcomes.”

Eliot Siegel, MD, Associate Vice Chair of Diagnostic Radiology and Nuclear Medicine at the University of Maryland School of Medicine said, “The ability of medical imaging – in combination with AI – to better discover and quantify the burden of COVID-19 has been well-documented. There would be tremendous clinical value in an AI algorithm that could establish and utilize a trajectory of change to predict which subset of patients might need more intense therapy such as medical ventilation, which subset of patients could be more confidently discharged, and predict subsequent clinical course. Today, there are many promising AI applications that have emerged that could allow us to address the major challenges that have hit the healthcare sector during the pandemic, and beyond as we plan to treat patients with COVID-related complications and as we provide diagnostic and therapeutic procedures that were delayed during the surge.”

Combined Study Results Indicate Possibilities for Lung Cancer Screening in New Zealand

Lung cancer screening might be one step closer to fruition in New Zealand thanks to newly discovered results by the University of Otago, published by medical journal BMJ Open. The indigenous Māori people of New Zealand are particularly susceptible to lung cancer, as their mortality rates are between three and four times higher than other ethnic groups. Around 450 Māori are diagnosed with lung cancer, and approximately 300 die from it yearly. If caught in the early stages, health outcomes for the Māori and other ethnic groups will undoubtedly improve.

To assess whether low-dose computerized tomography (LDCT) might be a cost-effective way to screen for lung cancer, Waitematā and Auckland DHBs collaborated with University of Otago researchers. Led by Associate Professor Sue Crengle (Kāi Tahu, Kāti Mamoe, Waitaha) from the University of Otago, the researchers used scientific modeling to estimate the benefits and costs of LDCT screening when it comes to a high-risk population. LDCT uses a small amount of radiation to produce an extremely clear three-dimensional image from a computerized x-ray.

“Having clarity about the cost-effectiveness of lung cancer screening provides further impetus to get this work started,” Associate Professor Crengle says. “If this works for Māori, then it will work for everyone else as well.”

Study findings suggested a national biennial lung cancer screening program is likely beneficial in terms of cost-effectiveness for not only the Māori but also the entire population of New Zealand. With early screening, the number of deaths will be reduced among the indigenous people. Countries with screening trials have seen a 20 to 26 percent reduction in lung cancer deaths.

Radiotherapy Market Revenue to Expand by Eight Percent by 2030

In 2019, the global radiotherapy market revenue was set at $7,222.4 million. According to a P&S Intelligence report, an increasing number of cancer cases will cause revenue to climb by eight percent to $17,194.4 million by 2030.

Cancer is the second-leading cause of death in humans, killing 9.6 million people annually, according to the World Health Organization. The American Institute of Cancer Research estimates that by 2030, around 25 million cancer cases will be diagnosed yearly.

North America’s high incidence of cancer makes it the largest radiotherapy market globally. Additionally, established radiotherapy system providers and highly developed healthcare infrastructure are factors in the market scope. Residents in Canada and the United States have a higher level of disposable income than other countries, which allows them to afford treatment more quickly.

Due to the coronavirus pandemic, the radiotherapy market is subsequently experiencing growth as the focus of healthcare shifts from chronic disease to remedying the virus. What once were cancer-specialty hospitals are now COVID-19 care centers. Despite the circumstances, several hospitals are reopening their cancer wards, thereby increasing radiotherapy treatments.

Companies providing solutions to the increasing radiotherapy market opportunities are collaborating by creating partnerships and other working agreements in order to gain distribution partners for their equipment, offer clinicians a joint resolution of image-guided radiotherapy systems and Electronic Medical Record (EMR) platform, develop innovative markers for pre and clinical neurological and oncologic purposes, provide hospitals with cutting-edge proton therapy capabilities, and advance the radiotherapy system motion-tracking and rectification technologies.

Researchers Create 3D CT Models of Lung Segmentation in COVID-19 Patients

A Louisiana State University (LSU) radiologist joined with an evolutionary anatomist to create revolutionary 3D models of COVID-19 patients’ lungs by implementing the same techniques used for reptiles and birds. Emma R. Schachner, Ph.D., Associate Professor of Cell Biology & Anatomy, and Bradley Spieler, MD, Vice Chairman of Radiology Research and Associate Professor of Radiology, Internal Medicine, Urology, & Cell Biology and Anatomy at LSU Health New Orleans School of Medicine, created the models from CT scans of COVID-19 patients.

Three patients underwent contrast-enhanced thoracic CT when their symptoms worsened. Two tested positive for COVID-19; another was presumed a false-negative based on the symptoms they experienced combined with compelling imaging. Since false-negative tests are a known diagnostic challenge, CT can be beneficial for establishing a COVID-19 diagnosis. The lungs’ form and structure appear to correlate to disease progression, which allows for the 3D segmentations to model airflow patterns or quantify lung tissue volumetrically.

Spieler said, “The full effect of COVID-19 on the respiratory system remains unknown, but the 3D digital segmented models provide clinicians a new tool to evaluate the extent and distribution of the disease in one encapsulated view. This is especially useful in the case where RT-PCR for SARS-CoV-2 [current testing system] is negative but there is a strong clinical suspicion for COVID-19.” 

This combined technology is a novel discovery as there has never before been accurate models of the COVID-19 disease progression in the lungs. Previous models published include volume-rendered models and straight 2D screenshots of CT scans and radiographs (X-Rays). The 3D models are vastly more detailed but do require some more effort.

Schachner explained, “Previously published 3D models of lungs with COVID-19 have been crated using automated volume rendering techniques. Our method is more challenging and time-consuming, but results in a highly accurate and detailed anatomical model where the layers can be pulled apart, volumes quantified, and it can be 3D printed.”

The in-depth view rendered by this model makes it easier for the broader medical audience to understand the severity and extent of this disease.

Radiation Therapy Might be a Treatment Option for COVID-19

A recent article by the Journal of Nuclear Medicine is one of the first published studies to examine radiation therapy to treat COVID-19 patients. Researchers in New York radiolabeled the CR3022 human antibody with Iodine-131 as a targeted agent, since this antibody binds to the SARS-CoV-2 virus.

The researchers concluded, “Our results confirm the potential of CR3022 as a molecularly targeted probe for SARS-CoV-2. A labeled version of CR3022 could potentially be used for Auger radiotherapy or non-invasive imaging.”

National Institutes of Health (NIH) Director Francis Collins, M.D., Ph.D., authored a blog on the CR3022 human antibody, stating it might hold the key to developing effective therapy against COVID-19. Collins wrote that researchers had shown CR3022 cross-reacts with the new coronavirus, though the antibody does not bind tightly enough to neutralize and cease infecting cells. Vaccine designers could potentially leverage the capabilities of how precisely the antibodies attach to the virus.

Although it seems novel, radiotherapy has been considered for treating viruses in the past. A genetically-engineered measles virus that expressed the sodium iodide symporter in infected cells was sensitive to I-125 in vitro. This halted virus replication but could not translate to an in vivo model.
