4. Fig 3
Comparison of an ultrasound image of the interscalene brachial plexus (the arrows indicate the C5–7 nerve roots; SCM, sternocleidomastoid muscle; ASM, anterior scalene muscle; MCM, median scalenus muscle) with two different qualities. (a) Illustration from 2004; (b) most recent illustration with improved image quality due to speckle suppression.
