Diagnostic Imaging

 

By 2030, an estimated 65.7 million people are predicted to be affected by Alzheimer’s disease (AD), a 30 million person jump from today’s total. But, there’s increasing evidence that biomarkers coupled with the correct imaging technique may provide crucial insights into the disease.

Postoperative CT, most notably 3D CT scans, are the preferred imaging technique in evaluating intra-articular screw penetration of proximal humerus fractures, according to a study published in Academic Radiology.

Headaches are common in children, and many tools, often related to neuroimaging, exist to diagnose the situation, but there remains little standardized procedure in approaching individual cases and little clarity around the benefits and risks of pursuing imaging.

A recent retrospective study of brain and spinal MRI of patients suspected or known to have multiple sclerosis showed that the introduction of a structured reporting template produced reports with more adequate information for clinical decision making. The results were published in the American Journal of Roentgenology

Abdominal radiographs have been used to diagnose functional constipation in children and adolescents, despite a lack of evidence showing reliability. Researchers from the Boston Children’s Hospital examined how gastroenterologists use the images in diagnosing young patients.

ED slashes average MRI wait times with severity-based queues

After developing and implementing a tiered MRI prioritization system based on patient severity, the emergency department at Lahey Hospital & Medical Center in Massachusetts successfully cut its overall average order-to-imaging start times from 4.1 hours to 2.7 hours.

Patient questionnaires improve rads’ reads for abdominal pain

Abdominal radiologists make more complete and precise diagnostic reads, and are more confident in their diagnoses, when they’re armed at the reading station with clinical information supplied by patients via questionnaire, according to a study published online June 24 in Abdominal Radiology.

Mobile CT inside trauma bay no faster than the scanner next door

In theory, having a mobile CT scanner available in a trauma resuscitation bay should save workup time over relying on a scanner near but not inside the bay. In reality, it doesn’t make a meaningful difference.

No measurable gadolinium in children’s brains even after multiple doses

Gadolinium-based contrast agents (GBCAs) in the macrocyclic category have proven safe enough in children to be considered the standard of care across pediatrics whenever contrast-enhanced MR imaging is indicated, according the authors of a European study published online June 21 in Radiology.

Medical school adds radiology component to year-1 anatomy instruction

First-year medical students at a historically black university in the nation’s capital are getting a deep introduction to the basics of radiology.

Nimble MRI compares well with established PET-CT in dementia neuroimaging

Practical and noninvasive, MRI with arterial spin labeling may substitute for PET-CT with the radiotracer 18FDG, which requires intravenous injection, for imaging the brains of patients with suspected early-stage dementia.

Anti-anxiety medications change the brain

Benzodiazepines—the family of popular sedatives that includes Valium, Xanax and such—seem to bring about structural changes in the brain, according to a European study running in the August edition of Psychiatry Neuroimaging.

Aging women suffer more lumbar disc degeneration, MRI study shows

Lumbar MRI for low-back pain may be under constant suspicion of overutilization, but findings from a Chinese study suggest it’s often appropriate for a very substantial subset of the general population: postmenopausal women.

Elevated amyloid proves a warning sign of cognitive decline to come

People with elevated amyloid levels in the brain but no signs of cognitive decline are indeed more likely to develop impairment down the road, potentially leading to full-on Alzheimer’s, according to a study published online June 12 in JAMA.

Prenatal alcohol exposure changes babies’ faces, suggesting possible neuro effects

Mothers-to-be who drink alcohol, even in modest amounts, are putting their babies at risk of facial changes—and the differences may point to effects in the brain.
