Deep learning can estimate full-dose PET images from scans with significantly lower dosages, according to a new study in the Journal of Digital Imaging. The method may make performing PET scans safer and more affordable.

Using focused ultrasound, researchers from the Stanford University School of Medicine in California have developed a noninvasive method that helps deliver drugs to within a few millimeters of a targeted area of the brain, according to a study published online Nov. 7 in the journal Neuron.

By assessing the degree of variegation in the white matter of children’s brains using diffusion-weighted MRI, neuroradiologists can predict how well the kids will perform in memory tests.

After more than 30 years, a domestic supply of the radioisotope Iodine-131 (I-131) is now available for diagnostic imaging and thyroid cancer treatment.

Researchers from the Medical University of Vienna in Austria provided new guidance for selecting optimizing features from 18F-FDG-PET/CT studies—demonstrating feature variations can be minimized for selected image parameters and imaging systems, in a new study published Nov. 2 in the Journal of Nuclear Medicine.

Incidental renal lesions are commonly detected during lumbar spine MRI examinations. When that occurs, is follow-up imaging always necessary? The authors of a new study published in the American Journal of Roentgenology explored that very question.

Inhibiting a certain class of cyclin-dependent kinase (CDK) proteins could protect cancer patients from chemotherapy-induced heart failure—the second leading cause of death in the demographic after cancer recurrence—according to research published in the Journal of Biological Chemistry.

MRI can effectively diagnose appendicitis in pediatric patients even when performed in a non-pediatric setting by radiologists not trained in the specialty, reported authors of a new American Journal of Roentgenology study.
