Study eyes interventional rads and opioid prescriptions
Interventional radiologists write relatively few prescriptions for their patients, yet some prescribed opioids more frequently than other physicians did for Medicare beneficiaries in 2015, according to a study published online February 21 in the Journal of the American College of Radiology.

CCTA usage rate rises sharply, but still eclipsed by MPI
The use of coronary CT angiography (CCTA) to evaluate chest pain in the emergency department has grown exponentially, but clinicians are still using myocardial perfusion imaging (MPI) far more frequently, according to research published online February 15 in the American Journal of Roentgenology.

Ultralow-dose CT slashes radiation dose for fractures
Just how low can CT radiation dose go? Researchers from New York City found that radiologists performed well when reading extremity trauma scans acquired with an ultralow-dose protocol with dose levels approaching those of x-ray, according to a study published in the Journal of Orthopaedic Trauma.

2D/3D hybrid interface refreshes diagnostic imaging
A new display interface for radiology workstations combines virtual reality with a traditional 2D interface to provide simultaneous 2D and 3D visualization of medical images. Using it helped radiologists improve their diagnostic performance in a study published in the February issue of the Journal of Digital Imaging.

French find no need for CT to rule out PE
French researchers found that a set of clinical criteria was just as accurate as a protocol that included CT pulmonary angiography for ruling out pulmonary embolism (PE) in the emergency department, according to an article published in the February 13 issue of the Journal of the American Medical Association.

5 ways to optimize CT lung cancer screening
An academic hospital that implemented a CT lung cancer screening program obtained similar detection rates as the National Lung Screening Trial. But it also encountered challenges that needed to be addressed to improve the quality of screening, which researchers describe in a new study published in Academic Radiology.

Is CT or MR perfusion better for diagnosing CAD?
Recent advances in scanner technology have made the use of CT stress myocardial perfusion imaging feasible. Just how well it matches up to MR perfusion in the diagnosis of coronary artery disease (CAD) is the central question of a study published in the February issue of Radiology.

Highly processed foods affect muscle quality
By Will Morton
MRI scans have revealed that eating ultraprocessed foods is associated with higher amounts of fat stored inside thigh muscles.
December 4, 2024
Axial T1-weighted bilateral thigh MR images and magnified frames providing a closer look at the areas in lateral aspects of quadriceps femoris muscles (knee extensors) from two obese, female participants, aged 58 (A) and 62 years (B), respectively. In A, the thigh muscles on both sides demonstrate abundant fatty streaks, consistent with a high Goutallier grade for this participant, whose diet from the past 12 months consisted of 68% ultraprocessed foods. In B, the thigh muscles show fewer fatty streaks as highlighted in the magnified image, consistent with a low Goutallier grade for this participant, whose diet contained only 36% ultraprocessed foods.

35-year-old transgender woman presents with (A) a 3D CT reformation of the face in the sagittal plane showing a left mandibular fracture (arrow). (B) An axial head CT image from one of three head CT studies over the last two years reveals right periorbital soft tissue swelling (arrow). The radiologist reader suspected intimate partner violence based on radiology reports, which was subsequently confirmed through clinical note examination. Image courtesy of the RSNA.
