Fig.1 - Long axis gray scale image of right forearm displaying the median nerve situated between deep and superficial flexor muscles. 2 - Power Doppler sensitivity along median nerve assists in the display of a prominent median artery. 3 - Transverse Power Doppler demonstrates increased blood flow around and within the median nerve.
Median nerve appears bi-lobed with a small central cleft.
5 - Transverse Power Doppler image shows decreased level of hyperemia which is compatible with clinical improvement. Many of the figures are easier to read on the print copies than they are here. To receive your own copy, send email to GE and reference publication number 96-4527.
