Radiology News and Research

RSS

Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

Machine-learning algorithm can detect early, subtle signs of osteoarthritis

Researchers at the University of Pittsburgh School of Medicine and Carnegie Mellon University College of Engineering have created a machine-learning algorithm that can detect subtle signs of osteoarthritis- too abstract to register in the eye of a trained radiologist- on an MRI scan taken years before symptoms even begin.

PET/MRI reduces radiation exposure, improves lesion detectability in select cancers

A single-center observational study of more than 1,000 oncological examinations has demonstrated that positron emission tomography/magnetic resonance imaging (PET/MRI) facilitates cancer staging as well as PET/computed tomography (PET/CT) and improves lesion detectability in select cancers, potentially helping to promote fast, efficient local and whole-body staging in one step.

High school athletes are at risk for concussions and may need a longer recovery than thought

A recent study from the Henry Ford Sports Medicine Research team suggests that high school athletes competing, not only in football, but in soccer, hockey, basketball, swimming, cheerleading and other sports are not only at risk for concussions, but may need a longer recovery than first thought.

New strategies may be needed to reduce risk of falls in Alzheimer’s patients

To better understand why people without cognitive symptoms are at risk of falling, first author Audrey Kelemen, a graduate student in Stark's lab, and colleagues followed 83 people over age 65 for a year.

Higher doses of Botox may lead to bone loss, shows study

Botox injections to manage jaw and facial pain do not result in clinically significant changes in jaw bone when used short term and in low doses, according to researchers at NYU College of Dentistry.

Researchers develop new PET imaging agent that spotlights inflammation

Many of the most common diseases -- cancer, diabetes, cardiovascular and lung disease, and even COVID-19 -- have been linked to chronic or excessive inflammation.

Facing COVID-19 patients on ventilators down may cause nerve damage

Some people are more likely to experience severe coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These include the elderly, people who are obese and have underlying medical conditions, such as diabetes, obesity, heart disease, lung illness, and kidney disease, among others.

Severely ill COVID-19 patients on ventilators can experience permanent nerve damage

Severely ill COVID-19 patients on ventilators are placed in a prone (face down) position because it's easier for them to breathe and reduces mortality.

Study demonstrates new method to synthesize gold nanoparticles in cancer cells

Dipanjan Pan, professor of chemical, biochemical, and environmental engineering at UMBC, and collaborators published a seminal study in Nature Communications that demonstrates for the first time a method of biosynthesizing plasmonic gold nanoparticles within cancer cells, without the need for conventional bench-top lab methods.

Portable, low-field MRI device can be safely used at patient bedside, shows study

A portable, low-field magnetic resonance imaging (MRI) device can be safely used at bedside in complex clinical care settings to evaluate critically-ill patients for suspected stroke, traumatic brain injury (TBI), or other neurological problems, results of a proof-of-concept study show.

Study compares clinical outcomes of Ellipsys and WavelinQ-4F pAVF devices

Two devices for creating minimally invasive dialysis access--the Ellipsys® Vascular Access System and the WavelinQ™ 4F System--demonstrated high rates of technical success and low rates of complications, according to a new study published in the Journal of Vascular and Interventional Radiology.

Study: Without proper public education, wearing masks could lead to more COVID-19 infections

A novel new study suggests that the behavior public officials are now mandating or recommending unequivocally to slow the spread of COVID-19 - wearing a face covering - should come with a caveat. If not accompanied by proper public education, the practice could lead to more infections.

Researchers aim to improve digital thermal imaging as a tool for monitoring cancer

Thermal imaging has been available for decades to detect temperature differences on the skin that could signal breast cancer without exposing patients to radiation, although the method is not as reliable as mammography.

Focal high-intensity focused ultrasound ablation is an effective treatment for prostate cancer

For some prostate cancer patients, radical treatment (surgery or radiation) are treatment standards. However, these procedures may cause side effects including urinary incontinence or impotency.

Chest X-rays found to be highly predictive of COVID-19

A team of LSU Health New Orleans radiologists investigated the usefulness of chest X-rays in COVID-19 and found they could aid in a rapid diagnosis of the disease, especially in areas with limited testing capacity or delayed test results.

Suppressing tumor's growth and spread from the inside

A new technology that allows researchers to peer inside malignant tumors shows that two experimental drugs can normalize aberrant blood vessels, oxygenation, and other aspects of the tumor microenvironment in non-small cell lung cancer, helping to suppress the tumor's growth and spread, UT Southwestern researchers report.

Ellipsys Vascular Access System reduces time for dialysis treatments

The Ellipsys Vascular Access System reduces the time before patients with kidney failure can start lifesaving dialysis treatments, while requiring fewer secondary procedures, according to a new study led by interventional radiologist Jeffrey Hull, M.D., of Richmond Vascular Center.
