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.

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).

VIDEO: Congenital heart imaging with cardiac CT

As the population of patients with adult congenital heart disease grows, they are presenting to adult cardiology clinics and being imaged with CT. Many also do not have access or cannot be imaged by MRI, said Renee Bullock-Palmer, MD.

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.

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.
