Computer scientists, rheumatologists and immunologists have pooled skill sets to develop a neural network that can distinguish between rheumatoid and psoriatic arthritis while also recognizing healthy joints with no arthritis at all.

Outside of the correlation between measurements obtained using both modalities, the researchers also identified Hounsfield unit thresholds that could reliably rule out osteoporosis.

A study published this week in Radiology found that 12 months after hospitalization for COVID pneumonia, 93% of patients’ lung abnormalities had cleared up on follow-up chest CT scans.

With the shortage, which pertains specifically to all formulations and concentrations of GE Healthcare’s Omnipaque (iohexol), expected to last until mid-June, several organizations have alluded that conservation efforts are of critical importance.

Leslee Shaw, PhD, director of The Blavatnik Family Women’s Health Research Institute, Mount Sinai Hospital, New York, explains how cardiac computed tomography (CT) can be used to assess coronary plaques.

"This awareness is important to avoid oversight of symptoms like dyspnea and vague chest discomfort, which can easily be interpreted as symptoms caused by the known disease COPD,” experts involved in the study said.

All formulations and concentrations of GE Healthcare’s Omnipaque (iohexol) are expected to be in short supply until mid-June due to COVID lockdowns where the contrast is manufactured.

Siemens Healthineers showed examples at ACC 2022 of cardiac computed tomography (CT) from its new Naeotom Alpha photon-counting CT scanner cleared by the FDA in 2021.
