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.

Some long COVID patients display 'severe' changes in their brain

For patients with anxiety and depression, even mild cases of long COVID could result in functional and structural alterations of the brain.

Including radiologists in radiotherapy prep bolsters quality of care

Many radiation oncologists are not formerly trained in imaging interpretation, and radiologists’ collaborative participation in care planning can help to catch errors, experts wrote recently.

Expert left 'astounded' by gadolinium discovery

New data out of the University of New Mexico suggest that the imaging agent’s physiologic reach may exceed what was previously believed.

Older women with breast cancer can safely forego radiation therapy

New data suggest that it may not be necessary for women older than 65 with hormone receptor-positive breast cancer to undergo radiotherapy after breast-conserving surgery and hormone therapy, as it does not impact death rates or metastasis risk.

How effective are chest CT severity scores in managing COVID?

While the studies on these systems have proven them to be effective in diagnosing and treating COVID in specific cohorts, the varying settings in which they were used can make it difficult to derive definitive conclusions on their efficacy.

GE HealthCare recalling nuclear imaging systems as FDA warns of dangerous consequences

The FDA alerted patients and providers about the issue Feb. 15, labeling it as the agency’s “most serious” type of recall.

Some long COVID patients continue to display multi-organ damage one year after recovery

A new study utilizing multi-organ MRI scans recently identified organ impairment in 62% of COVID long haulers six months after their initial diagnosis; 29% of these individuals continued to display damage in at least one organ at the 12-month mark.

Ed Nicol, MD, consultant cardiologist and honorary senior clinical lecturer with Kings College London and president-elect of the Society of Cardiovascular Computed Tomography (SCCT), explained artificial intelligence (AI) in cardiac CT is here to stay and its use is expanding. He noted that one AI-based algorithm is already included in recent cardiology guidelines and more will likely follow. #SCCT

Cardiac imagers need to understand AI as it enters clinical use and ACC guidelines

Most FDA-cleared AI algorithms are related to radiology and cardiology, meaning radiologists and cardiologists need to make an effort to learn how these technologies work.
