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. 

Mahadevappa Mahesh, PhD, professor of radiology and a medical physicist at the Johns Hopkins University School of Medicine, explains a new American College of Radiology (ACR) effort to ensure that lower radiation dose X-ray images under Image Wisely and As Low as Reasonable Achievable (ALARA) meet diagnostic reading standards. He spoke to Radiology Business at the Radiological Society of North America (RSNA) 2022 meeting.

Bedside ultrasound found to effectively guide clinical decisions in trauma patients

Although whole-body CT scans are frequently one of the first assessments in the triage of trauma patients, new research argues that the use of bedside ultrasound could be more appropriate for initial examinations. 

Regularly eating avocados is associated with a reduced risk of cardiovascular disease, according to a new study.

Why clinicians should know if patients are on the keto diet before undergoing PET imaging

Patients adhering to a ketogenic diet can show reduced cerebral 18F-FDG uptake on PET imaging, study shows.

Microwave breast imaging: A non-invasive, non-ionizing emerging technology for breast cancer screening

“This can have a major impact on the younger population, especially for women at high risk of developing breast cancer, like those with genetic mutations, where there is a necessity to start screenings at an early age,” experts explained in Academic Radiology.

Radiologist- and technologist-related errors to blame for most musculoskeletal MRI recalls

These errors are frequently due to a breakdown in communication between radiologists, technologists and referring providers, either before or during exams, according to a new analysis of more nearly 63,000 musculoskeletal MRI exams.

CMS cites 'newly published evidence' in postponement of PET coverage decision

Prior to the Dec. 15 announcement, CMS had released a different statement in June informing the public that they were reconsidering the amount of PET scans that Alzheimer’s patients undergoing monoclonal antibody treatment can receive.

ACR recommendations result in 15-fold increase in breast MRI eligibility among cancer survivors

Prior to 2018, it was recommended that women at higher-than-average risk undergo supplemental breast MRI screening only if they had a personal history of breast cancer in addition to carrying a hereditary breast cancer gene mutation.
