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.

FDG PET/CT spots COVID-induced pancreatitis

There are limited data to determine whether pancreatitis in COVID patients is the result of a stress response triggered by severe illness or by direct damage to the β-cell structure and function.

Bruce Haffty, MD, president of Radiological Society of North America (RSNA) Board of Directors, chair of radiation oncology, associate vice chancellor for cancer programs at Rutgers Cancer Institute of New Jersey and system director of radiation oncology at RWJBarnabas Health, discusses the president’s address "Diagnostic Imaging: Value From the Lens of the Patient," with Radiology Business. Haffty will present his opening session at RSNA 2022 at 4 p.m., Nov. 27, 2022, in the Arie Crown theater.

How AI-generated 'fake' X-rays can further medical research

But how reliable can synthetic radiologic images be in research settings? Are they as good as the real thing? 

James Udelson, MD, from Tufts and an investiogator in the PRECISE trial, explains how FFR-CT combined with coronary CT outperformed the standard of care in patients with stable chest pain, or low-risk patients with suspected coronary involvement.

VIDEO: PRECISE trial shows cardiac CT with FFR-CT significantly improves patient outcomes

James Udelson, MD, an investigator involved with the PRECISE trial, explained how patient outcomes were improved by 70% from the current standard of care.

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer.
