COVID-19

Outside of the loss of human life due to the COVID-19 pandemic, the past two years have greatly affected hospitals, health systems and the way providers deliver care. Healthcare executives are grappling with federal monetary assistance, growing burnout rates, workforce shortages and federal oversight of vaccines and testing. This channel is also designed to update clinicians on new research and guidelines regarding COVID patient treatment strategies and risk assessments.

'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.

MRI data reveal how pandemic-related stress physically aged the brains of teens

Researchers involved in the study suggested that, until now, this sort of growth acceleration in adolescents had only been observed in children who had experienced extreme adversity, such as violence, neglect and family dysfunction.

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.

'Significant' brain abnormalities shown to persist 6 months after COVID recovery

The regions that displayed the most significant differentiations in susceptibility values are known to be associated with neurological conditions such as fatigue, insomnia, anxiety, depression, headaches and other cognitive issues—all common complaints among many COVID long haulers. 

Iodinated contrast use before, during and after COVID: Trends predict significant growth in demand

A new analysis suggests that, if the use of iodinated contrast were to follow pre-pandemic trends, it could rise by as much as 37% from 2019.

New study may give insight into the neurologic dysfunction of some long-COVID patients

Vessel wall imaging—an MRI technique that offers high resolution images of the vessel wall—may hold clues as to the mechanisms by which COVID infections continue to cause neurologic symptoms after initial recovery in some patients.

Chest X-rays alone ineffective in COVID triage

New research indicates that there is significant reader variability in COVID classifications among different specialties when chest X-rays alone are the diagnostic tool of choice.

Some long COVID patients display thyroiditis on imaging a year after recovery

Though it is not yet clear why some COVID patients develop thyroiditis and some do not, researchers maintain that their findings “support the hypothesis of a direct thyroid gland involvement in SARS‐CoV‐2 infection.”

Debra L. Monticciolo, MD, past president of both the Society of Breast Imaging and the American College of Radiology, explains the advantages and disadvantages of current breast screening technology.

The new guideline details the best imaging strategies for a variety of clinical scenarios. 

"We are on the edge of a new journey in nuclear cardiology," explained ASNC President-elect Panithaya Chareonthaitawee, MD.
