Diagnostic Imaging

 

In resource-strapped parts of the world, point-of-care ultrasound can help palliative care clinicians provide better care for patients with life-limiting conditions and, in turn, offer more confident guidance to these patients’ families, according to a study published online Nov. 15 in the Journal of Clinical Oncology.

Athletes suffering suspected tears of the anterior cruciate ligament (ACL) are often adequately assessed with clinical diagnostic tests performed in the clinician’s office. When these are inconclusive, diagnostic arthroscopy is the gold standard—and MRI is a generally low-value option due to its time and cost burdens.

Parents may start to reconsider treatment options when it comes to the effects of anesthesia on their children thanks to new findings from Boston Children's Hospital. 

Radiology researchers at Children’s National Health System in Washington, D.C., have shown that infrared thermal testing is better than the human touch at finding wear spots and other defects in protective lead aprons.

After getting imaged, outpatients expect to hear back on the results within one to three days. If the wait goes longer than that, they’re likely to feel worried—or perhaps perturbed—and call in for themselves within five days, according to researchers at the University of Michigan.

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.

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.

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.

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.
