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.

AI speeds, improves chest X-ray interpretations

Six radiologists interpreting around 500 chest radiographs with an assist from AI bested unaided radiologists in measures of efficiency and/or accuracy in a new comparative performance study.    

MRI exams reveal the impact of steroid use on the brain

Experts involved in the study suggest that their findings could help explain the neuropsychiatric effects seen in many patients who are prescribed steroids long-term.

Automated CT body composition analysis predicts risk of stroke and heart attack

Researchers observed visceral fat area (VFA) measurements derived from abdominal CT scans to be associated with increased cardiovascular risk.

Experts describe how long-term lung abnormalities of COVID patients present on imaging

Up to one-third of patients hospitalized with COVID-19 pneumonia have abnormalities on chest CT 12 months after infection.

Breast cancer screening a bellwether service in radiology’s drive to bridge the ‘digital divide’

Mammography practices need to continue supporting pre-Digital Age channels for patients to schedule appointments, participate in community health programs and receive annual screening exams in mobile settings close to where they live. 

Synthetic MRI measures predict breast cancer treatment responses, according to new research

Researchers suggested that the quantitative measures derived from synthetic MRI exams could be used to help guide treatment decisions for breast cancer patients.

Surveillance breast MRI

Surveillance breast MRI findings linked with future second cancer

The new research focused specifically on associations between background parenchymal enhancement—a known risk factor for breast cancer, visualized on surveillance MRI exams—and secondary breast cancers.

Ultrasound measurements can predict osteoporosis, study shows

Experts compared the cortical thickness of three bones—the radius, tibia and second metatarsal—of 200 volunteers who had undergone prior bone mineral density measurements to evaluate the ultrasound method’s accuracy.
