Diagnostic Imaging

 

Children presenting with symptoms of low-impact neck trauma are better imaged with MRI than with x-ray—and not just because of the radiation avoidance, according to a study published online Dec. 6 in Child’s Nervous System, the journal of the International Society for Pediatric Neurosurgery.

Does the insurance pre-authorization process help weed out pediatric patients who have knee abnormalities that aren’t serious enough to warrant an MRI? 

The use of abdominal MRI doubled over the past eight years, partly due to concerns about ionizing radiation inherent to other exams such as CTAs awareness is raised about the potentially harmful effects of imaging, providers have switched to non-ionizing modalities, particularly for conditions that require frequent imaging.

Astronauts on extended missions know to expect visual impairment that could be serious and permanent if not treated quickly upon returning to earth. Researchers now know the cause of the unfortunately predictable—and potentially preventable—problem, according to study findings presented at RSNA. 

The shared environment of twins—possibly in utero as well as in childhood—ups the risk of brain incidental findings associated with autism spectrum disorder (ASD) in both siblings even when only one of them has ASD, according to an MRI-based study published online Nov. 22 in Autism Research.

Non-invasive liver MRI could improve cirrhosis diagnoses

Damage to the liver, primarily in the form of cirrhosis, is notoriously difficult to observe in a non-invasive manner. But a team of researchers in the U.K. have developed a method of using MRI to estimate the pressure in the liver, which can be signs of scarring and problematic circulation.

Consumers who search the Internet for information on abdominal imaging are likely to encounter much material that’s intended to be reader-friendly yet lies beyond their grasp, according to a study published online Nov. 12 in Abdominal Radiology.

Avoiding pitfalls in pediatric chest radiography

Pediatric chest radiography is a prime tool used for patients. However, it could be challenging to use with younger patients in many cases, ultimately resulting in potential mistakes.
