[Scanning Technique in Wrist and Hand Ultrasonography].

This guide to ultrasound examination of the wrist and hand describes the basic scanning planes and contains corresponding high-resolution ultrasound images. The patient and probe positionings are explained in a simplified step-by-step manner using schematic drawings. This standard and simple examination technique seems to be an appropriate way to improve the learning curve of novice musculoskeletal sonographers.
