Ultrasound

Ultrasound, also referred to as sonography or diagnostic ultrasound, uses high-frequency sound waves to visualize soft tissue. Ultrasounds are frequently ordered to measure fetal anatomy during pregnancy, check for blood clots and to guide needle biopsy procedures of the breast, abdomen and pelvis. The imaging modality does not use any radiation to create images. Find news specific to cardiac ultrasound (echocardiography).

Primary care POCUS on the Old Continent: Guidance needed, but at least 1 use case deemed ‘useful and feasible’

Two European studies illustrate opportunities and challenges presented by the growing appeal of point-of-care ultrasound to primary care practices.

New atherosclerosis treatment uses ultrasound-assisted lasers to break down plaque

The new technique is still in the development stage, but early research suggests it could provide clinicians with a new treatment option for breaking down arterial plaque. 

Cross-sectional imaging ordered downstream for just 15% of emergency POCUS patients

Using point-of-care ultrasound in emergency settings does not lead to overutilization of follow-up imaging with cross-sectional CT, MRI or additional ultrasounds. 

Foot ultrasound bested foot MRI on pooled sensitivity while lagging on specificity

MRI beats ultrasound at grading common foot injury, but tables turn for up-or-down diagnostics

Injuries of the plantar plate—the cluster of ligaments underneath the four smaller “knuckles” of the toes—are better assessed with MRI than with ultrasound scans. 

The GE healthcare vScan Air was one of several point of care ultrasound (POCUS) systems on display at the ACC 2022 meeting.

Major teaching hospital finds half its on-call abdominal ultrasounds call utilization into question

The investigators encourage radiologists to consider the numbers and take steps to “reinforce their gatekeeper function” to help cut ultrasound overutilization.
