Transplanted lungs react to COVID in a distinctive way

Clinicians treating COVID-19 patients who have transplanted lungs and lower airway infection should order molecular testing in addition to, or regardless of, imaging findings.

A new Alzheimer's drug therapy appears effective. What might this mean for the future of amyloid PET?

Previously, CMS determined that coverage for patients receiving treatment was dependent on their being enrolled in a CMS-approved clinical trial under coverage with evidence development (CED).

The results of a new trial offer “much needed progress” in the treatment of PD, experts involved in the study suggested.

New amyloid buster significantly hinders Alzheimer’s advance

An experimental Alzheimer’s drug therapy has slowed cognitive and functional decline by 27% versus placebo in a double-blind, randomized study of 1,795 individuals with early signs and symptoms of the disease.

For monitoring purposes, AI-aided MRI does what liver biopsy does with less risk, lower cost

Patients with autoimmune hepatitis may be better monitored across disease stages by AI-augmented multiparametric MRI than by liver biopsy, as the imaging has proven less costly and is inherently less risky due to its noninvasiveness.

The patient had no history of comorbidity.

COVID on X-ray, CT scan. What does COVID look like in medical imaging? Example of COVID imaging.

Vaccinated vs unvaccinated, Delta vs Omicron—how do these factors impact clinical and imaging features?

Vaccination rates likely had a role in reducing disease severity during Omicron, a new paper published in Radiology suggests.

RSNA to shutter print journals

Collectors of medical memorabilia may want to plan on preserving the January 2023 print edition of Radiology.

On review, popular imaging decision aid earns 1 thumbs-up—with caveats

With 91% sensitivity but only 25% specificity, the tool is worthwhile for clinicians who remain wary of frequent false positives that would send patients with no fractures for unneeded imaging.
