In the heavily fee-for-service payment environment of years past, many care decisions were driven by the ready availability of expensive technologies. Imaging advances stood among the most conspicuous precipitators of resource consumption. That world is fading fast, and for good reason, according to the authors of a paper published online Aug. 17 in the American Journal of Managed Care.

 - Mousing_Xray

Radiologists reading digital imaging exams move their mouses much more and tap their keypads far less than computer-bound nonradiologist workers, and that’s just one of several factors contributing to the rise of repetitive stress injuries (RSIs) in radiologists.

 - EarPlugs2

Despite being outfitted with substantial hearing protection, 26 young and healthy volunteers with no history of auditory problems or ototoxic drug use suffered a temporary yet troublesome shift in hearing threshold after undergoing brain MRI in a study conducted in China and published online Aug. 16 in Radiology.

 - HeadCT

Head CT does not increase patients’ risk of developing meningiomas, the usually benign but often slowly symptomatic brain tumors that have been suspected of forming more often in individuals exposed to concentrated doses of ionizing radiation.

 - Cognitive_Decline

Researchers at Case Western Reserve University have demonstrated a machine-learning algorithm that combines neuroimaging with neurophysiological, proteomic and genomic diagnostics to predict Alzheimer’s disease early on in its advance.

 - KidneyCT

Intravenous CT contrast does no harm to patients’ kidneys, according to a meta-analysis of 28 medical-journal articles involving more than 107,000 patients.

 - PET4Alzheimers

Younger Alzheimer’s patients have disproportionately more tau pathology on PET-CT imaging than older patients who are similarly symptomatic, according to a small multicenter European study. The authors suggest defective tau proteins alone can predict disease onset and progression, while later-developing Alzheimer’s likely owes to a confluence of contributing factors.

A 30-year-old former medical student in the United Kingdom has donated a kidney to one of his erstwhile professors as a way to thank her for inspiring him “to become a radiologist.”

 - DenseUS

Reviewing their group’s implementation of the fifth edition of the American College of Radiology’s BI-RADS Atlas, breast radiologists at the Medical University of South Carolina have observed considerable reader variability in determinations of which patients have dense breast tissue.

 - Appendicitis

MRI is as good as CT at confirming or ruling out acute appendicitis in children, teens and adolescents, and it doesn’t matter whether the reading radiologist is specialized in abdominal or pediatric practice.
