Diagnostic Imaging

 

Absent signs of cognitive decline or functional psychological falloff, retired contact-sport athletes can be helpfully but perhaps not definitively imaged for neurometabolite markers of concussion with MR spectroscopy, as the modality has performed with modest sensitivity in a preliminary study. 

Fifteen minutes can seem like an eternity to some patients undergoing MRI exams. Researchers have shown that some scans can be done in about a third of that time, and with no significant falloff in diagnostic performance. Their findings were published online Jan. 31 in the American Journal of Roentgenology.

Cognitive bias accounts for as much as three-quarters of malpractice suits filed against radiologists, according to findings published in 2013. A new paper lays out some ways rads can leverage quality-improvement (QI) projects to help steer clear of such mental shortcuts before they lead to missed or inaccurate diagnoses.

Two neurologists and a neuroradiologist had impressive concordance interpreting intracranial CT angiography images in a recent study in the Czech Republic, leading the authors to conclude that the neurologists’ diagnostic proficiency may point the way to faster interventions for acute stroke patients. 

Chinese researchers have shown that adult pneumonia can be quite precisely diagnosed with lung ultrasound, according to a study conducted by members of the intensive care unit at Hebei General Hospital in the province of Hebei.

FDA approves pocket sized osteoporosis diagnostic device

Most doctors will likely order a bone density x-ray scan for patients at risk of osteoporosis, and not only is that an expensive method but it also requires a physician referral. Now, the FDA has cleared a pocket-sized osteoporosis diagnosis device that might help physicians make the process of diagnosing the disease a bit easier.
