Cigarette smoke inhibits pulmonary perfusion while nicotine-delivering vapors from e-cigarettes do the opposite, actually increasing blood flow in the lungs. 

In a recent trial, medical students who were trained for two hours or less in an ultrasound “volume sweep” imaging (VSI) protocol obtained diagnostic-quality imaging of palpable breast lesions.

The study's authors noted that the ECG acquisition technology in these wearable devices appears to be quite effective. The automated algorithms, however, could still be improved. 

The shortage of iodinated contrast media that has rattled U.S. radiology since early May didn’t come from nowhere.

Two dozen academic physicians from around the U.S. with expertise in point-of-care ultrasound—and no vested interest in POCUS industry players—recently tested and compared four commercially available POCUS handhelds.

Experts observed significantly reduced pneumothorax and pulmonary hemorrhage rates of 8% and 6% when utilizing the method.

The FDA is notifying patients and referrers of another breast-imaging service’s slide into noncompliance with regulatory standards for image quality.

Fewer than 40% of rural counties in the U.S. can offer residents any access to point-of-care ultrasound, while nearly 90% of their metropolitan counterparts have POCUS aplenty.
