Establishing an Imaging Protocol for Detection of Vascularity within the Median Nerve Using Contrast-Enhanced Ultrasound.

This preclinical study was conducted to develop discrete sonographic instrumentation settings and also safe contrast dosing that would consistently demonstrate perineural vascularity along the median nerve. This set of imaging studies was conducted with a convenience cohort of young adult female monkeys (). Sonographic equipment settings and dosing were refined throughout the imaging series to ensure consistent contrast-enhanced ultrasound imaging.

An analysis of occupational factors related to shoulder discomfort in diagnostic medical sonographers and vascular technologists.

Objective: Three-fourths of diagnostic medical sonographers (DMS) and vascular technologists (VT) experiencing discomfort due to job demands indicate having discomfort in the shoulder region. An analysis of factors related to shoulder discomfort highlighted salient factors requiring further investigation and intervention.

Participants: The respondents were a convenient sample of DMS and VT that answered a survey, hosted on a secure website.

Morphologic Characterization of Intraneural Flow Associated With Median Nerve Pathology.

A prospective cohort of 47 symptomatic patients who reported for nerve conduction studies and 44 asymptomatic controls was examined with sonography to evaluate the median nerve. Doppler studies of the median nerve were collected with handheld sonography equipment and a 12-MHz linear broadband transducer. Strict inclusion criteria were established for assessing 435 waveforms from 166 wrists.
