An MRI-guided strategy for treating patients with rheumatoid arthritis (RA) showed no benefits over conventional treat-to-target approaches, according to a Feb. 5 study published in JAMA. The authors also found the modality showed no benefit in radiographic progression.

“This case emphasized the importance of a high index of suspicion in an unusual presentation of a common disease and the pivotal role of bronchoscopic intervention in malignant central airway obstruction,” Abdul Hanif Khan, MD, and colleagues wrote, in a new case report published by The BMJ.

University of Arizona in Tuscon researchers, led by Diego Martin, MD, PhD, chair of the university’s medical imaging department, have developed an MRI technique aimed to replace blood tests and invasive biopsies for measuring nonalcoholic fatty liver disease, according to a report by the Arizona Daily Star.

A group of researchers from the Republic of Korea found the 2018 Liver Imaging and Reporting Data System (LI-RADS) could accurately differentiate hepatocellular carcinoma (HCC) from other malignancy in patients with liver cirrhosis, according to a study published Jan. 29 in Radiology.

A team from Singapore demonstrated that an object detection convolutional neural network (CNN) could accurately detect and localize fractures on wrist x-rays, according to a Jan. 30 study published in Radiology: Artificial Intelligence. The method may be more verifiable than traditional CNNs.

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.
