Diagnostic Imaging

 

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.

Recent research using MRI has shown a frustrated parent’s threat that video games will “rot your brain” may be exaggerated, but the activity can change a player’s brain in fundamental ways.

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.

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.

Here’s one indication for which potential MRI overutilization could stand to be curbed: predictive imaging of patients with slipped capital femoral epiphysis (SCFE), the most common hip disorder in adolescent boys (although girls can get it too).

Emergency docs advised to exercise caution with solo CT interpretation

Comparing CT interpretations made by emergency physicians with those from radiologists reading the same scans, researchers in Iran found an agreement rate of 68.2 percent, leading them to urge caution among emergency doctors who feel pressured to supply their own reads for critical cases in the absence of an on-call radiologist.

Ultrasound shows efficacy of carpal tunnel treatments

Patients injected with a steroidal anti-inflammatory for symptom relief of carpal tunnel syndrome are well-served by follow-up imaging with ultrasound to show whether or not the treatment is working, according to a small study published online in Skeletal Radiology.

Human + computer combination improves follow-through on radiology recommendations

Following a review of radiology reports and patient records that turned up glaring communications gaps over noncritical yet potentially serious findings, an urban academic medical center has invested in software and dedicated staff to close the gaps and cut the associated risks for harm.

Neuro MRI shows cost-effective cognitive tests best for monitoring Alzheimer’s

Older patients with mild cognitive impairment (MCI) marked mainly by memory loss are most accurately evaluated with intensive neuropsychological test batteries. However, if such mental decline progresses to full-on Alzheimer’s disease, the patients are better monitored with the quicker, less costly Mini-Mental State Examination (MMSE).

Ultrasound excels at surveilling larger pancreatic cysts

Transabdominal ultrasound is an excellent tool for follow-up imaging of larger cysts on or in the pancreas, although its performance falls off as surveilled known lesions decline in size, according to a study published online Aug. 1 in Abdominal Radiology.
