With a "how-to" approach, the author meticulously describes the clinical evaluation of the peripheral nerves throughout the body using high-frequency ultrasound. Evaluations include both normal and pathologic findings, as well as discussions of relevant non-neurologic tissue. The book opens with an introduction to ultrasound physics, instrumentation, and image optimization. The remainder of the text is a highly visual tour through the multiple nerves of the shoulder, neck, and upper and lower limbs, focusing on sonographic technique and correct interpretation of findings. Clinical cases that integrate anatomic localization with clinical and electrodiagnostic assessment are incorporated throughout.
