To cut respiratory motion artifacts on liver MRI, have patients hold their breath at the end of an exhale rather at the end of an inhale. That’s the recommendation of Stanford researchers after testing and comparing the two techniques, and it holds for unenhanced and contrast-enhanced scans.

In Ontario, Canada, it is illegal to cremate a patient who has received the radiation treatment brachytherapy. Radiation experts are now calling on the province to change the law, according to a report by CBC News.

Measuring the effectiveness of treatment in metastatic melanoma patients is difficult, but a study published in the March issue of the Journal of Nuclear Medicine found 18F-FDG PET/CT could accurately monitor immunotherapy with ipilimumab in these patients.

Children and teenagers undergoing brain MRI scans experience little to no more claustrophobia or other form of anxiety than adults, so there’s no reason to exclude pediatric patients from MRI research on the basis of concern over stress. 

Canadian researchers working with Toronto General Hospital-University Health Network have developed a natural language processing (NLP) approach to predicting downstream radiology resource utilization, according to work published in the Journal of the American College of Radiology March 2.

MIT researchers have developed a near-infrared imaging technique that can detect tumors deep in internal tissue before the cancer grows beyond a few hundred cells.

Documenting contrast allergies in the electronic health record (EHR) is central for safe imaging, but a new study found such records are incomplete, misleading and often ambiguous. A multidisciplinary approach may be needed to solve the problem.

Though the idea of artificial intelligence displacing radiologists worries more than half of surveyed medical students interested in an imaging career, radiology programs have seen a spike in applications in recent years, according to work published in Academic Radiology.
