Fig 2 The sciatic nerve (SN) at the mid-femoral level partly surrounded by local anaesthetic, resulting in a successful block. The homogenous hypoechoic (dark) zone represents the local anaesthetic (LA).

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.
