Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

Jorge Soto, MD, chair of the RSNA Annual Meeting Program Planning Committee, chief of radiology, Boston Medical Center, and professor of medicine, Boston University School of Medicine, offers an overview of the trends, hot topics, and innovative research and technology at the Radiological Society of North America (RSNA) 2022 meeting.

Philips MRI

Growing contrast concerns accompany rising MRI volumes

More than half of surveyed radiologists worry about MRI contrast availability, yet almost all—99%—wish for contrast agents that would cut current gadolinium concentrations at least in half.

Patient with severe, lung damage from COVID. Images in a 54-year-old man with COVID-19–related acute respiratory distress syndrome and subsequent fibrosis. (A) Axial CT 2 weeks after admission shows diffuse ground-glass opacity (GGO) with reticular abnormality and traction bronchiectasis in right middle lobe, indicating organizing phase of lung injury. (B) Axial CT 6 months after admission shows decreased GGO but extensive traction bronchiectasis and architectural distortion, suggesting fibrosis. RSNA

Lung scarring occurs in up to 11% of patients recovered from COVID, regardless of infection severity

Researchers cannot yet determine whether these changes will progress or resolve in the long term.

Altered mental status and head CT: Study suggests the exam is overutilized at the expense of patients

The meta-analysis included 25 studies and nearly 80,000 patient cases. Experts found that while 94% of those patients with acute atraumatic AMS underwent non-contrast head CT scans, just 11% of those exams yielded positive results. 

Examples of breast imaging. What does breast imaging look like? What does breast cancer look like? What do radiologists look for on mammograms?

New findings ‘challenge the use of imaging surveillance’ after any mastectomy

Regardless of whether or not they received reconstructive surgery, post-mastectomy patients probably need no follow-up imaging for breast cancer.

Lung CT of a 42-year-old man with more than 7 days of symptoms. Scans show COVID pneumonia with diffuse ground-glass opacities in close vicinity of visceral pleural surfaces. In addition, a crazy paving pattern is observed. Image courtesy of RSNA. Medical images of COVID. #COVID #SARS-CoV-2

'Crash course' on COVID cases benefits residents less experienced with thoracic CT

Following the course, experts observed nearly perfect agreement between less experienced residents and chest-devoted radiologists.

Philips MRI

Amid looming helium shortage, Philips enters research agreement to study alternative cooling methods for MRI scanners

The healthcare industry accounts for close to 30% of global helium consumption, with MRI equipment needs accounting for a significant portion of that figure.
