Hospitalized women with ischemic stroke are less likely than men to be evaluated by stroke specialists and receive specialized imaging scans and other diagnostic testing in hospitals, according to research being presented at this year's American Stroke Association International Stroke Conference in Honolulu.

A team of national researchers has identified a set of multiparametric MRI-based guidelines and clinical features which can help clinicians easier determine a patient’s risk that their prostate cancer will spread, according to a Jan. 22 study published in Radiology.

A novel MRI approach developed by researchers from Austria showed promise for non-invasively measuring hypoxia and neovascularization in breast tumors, according to a Jan. 24 article published by Physicsworld.

A test that measures changes in a patients’ blood protein levels through blood samples, brain imaging and cognitive tests could detect Alzheimer's up to 16 years before symptoms appear, according to new research published online in Nature Medicine.

Four-dimensional (4D) MRI with dynamic contrast-enhanced (DCE) sequencing is a reliable method for localizing parathyroid lesions, reported authors of a single-center study published in the European Journal of Radiology.

Although Variant 3 of the American College of Radiology (ACR) Appropriateness Criteria recommends performing non-contrast head CT (NCCT) on patients with sudden severe headache who do not present other high-risk features, researchers from Johns Hopkins Medical Center in Baltimore, Maryland found that performing emergency department (ED) NCCT scans on these patents has little value.

Stationary digital breast tomosynthesis (sDBT) improved radiologists’ accuracy in detecting malignancies and was favored over mammography, reported authors of a Jan. 16 study published in Academic Radiology.

Radiolabeled 18F-fluoride PET/CT proved superior at detecting bone metastases (BM) than a comparative radiotracer, according to a Jan. 14 study published in Clinical Radiology.

Spectral CT with iodine mapping helps differentiate benign pleural metastatic tumors from cancerous lesions, reported authors of a Radiology study. The iodine overlays particularly helped less-experienced radiologists.
