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 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.

Common MRI findings in 'foot drop' cases

A new paper in the European Journal of Radiology offers an updated overview of common MRI findings in patients who develop foot drop following total hip arthroplasty.

Severe COVID patients continue to evidence lung abnormalities 2 years after initial infection

Scans on these patients show a combination of fibrosis, thickening, honeycombing, cystic changes and dilation of the bronchi, among other imaging features.

New contrast agent is officially available for use in hospitals and clinics

A Feb. 14 announcement from Bracco indicates that the recently FDA-approved, gadolinium-based contrast agent VUEWAY, also known as gadopiclenol, is officially being used for patients undergoing MR imaging.

Internal surgery patients with infectious complications shown not to benefit by extra CT

Thoracic CT is safely and wisely omitted from diagnostic protocols for ICU patients who have signs of infection after abdominopelvic surgery but were already imaged with abdominal CT.

Are MR arthrograms on their way out?

Once the go-to exam for gaining intra-articular details of major joints, MR arthrography appears to be wavering in popularity, decreasing 'drastically' at some institutions.

Homegrown tracking boosts follow-up imaging for incidental findings of uncertain gravity

A structured program to track incidental findings on body CT has significantly boosted rates of clinician follow-up as well as timely patient adherence to radiologist recommendations for next exams.
