When ultrasound reveals shoulder muscles that appear especially “bright,” it may be a warning sign of diabetes, according to findings to be presented at RSNA 2018 in Chicago.

Adding magnetic resonance spectroscopy (MRS) to MRI does not significantly improve the classification of brain tumors in clinical practice, although MRS may be a valuable supplement to MRI in certain cases, according to researchers from Sweden's Uppsala University.

Wayne, NJ—For the first time, radiologists will be able to view motion from standard X-ray images without fluoroscopy. Konica Minolta Healthcare is bringing digital radiography (DR) to life with the ability to visualize movement using conventional X-ray. Known as Dynamic Digital Radiography (DDR)* or X-ray in Motion™, this revolutionary new modality captures movement in a single exam and allows the clinician to observe the dynamic interaction of anatomical structures, such as soft tissue and bone, with physiological changes over time. The value of DDR in thoracic imaging is promising, allowing clinicians to observe chest wall, heart and lung motion during respiration. DDR goes beyond pulmonary function; Konica Minolta is exploring its use in orthopedic applications of the spine and extremities. This new capability will be showcased at the annual meeting of the Radiological Society of North America (RSNA), being held November 25-29 in Chicago, in Konica Minolta’s booth 1919.

Children presenting with signs of appendicitis should receive careful further evaluation if the usual first-line exam, abdominal ultrasound, fails to deliver a clear view of the vestigial digestive-system organ.

Researchers from the University of Strathclyde in Glasgow, Scotland, have developed a miniaturized version of a musical pipe organ, or a piezoelectric micromachined ultrasonic transducer (PMUT), that could potentially improve the quality of medical images.

Convolutional neural networks (CNNs) trained with 20,000 labeled images can accurately classify chest x-rays as normal or abnormal, according to new findings published in Radiology. Training the CNN with an additional 180,000 images, the authors noted, only yielded “marginal” benefits.

Anthropomorphic breast ultrasound phantoms can be a useful tool for radiology resident education programs, according to new research published in the Journal of the American College of Radiology.
