Computerized Real-Time Neuromuscular Sonography: A New Application,Techniques and Methods

Abstract

Diagnostic ultrasound has been extensively used for neurologic evaluation of cranial, vascular and spinal diseases. This study presents the techniques, methodology, and procedures for a new diagnostic application of ultrasound for evaluation of the neuromuscular system. In order to determine the optimum sonographic characterization of neuromuscular disease, normal anatomy has to be studied with ultrasound to develop a reproducible standardized methodology for routine use of ultrasound in neuromuscular imaging. To fulfill this objective, 30 subjects between the ages of 1 day and 59 years were studied with computerized real-time sonography. The results of this study are presented with illustration of the sonographic images of transverse and longitudinal planes of the upper and lower limbs. Computerization of optimum sonographic techniques, gradation of normal sonographic muscle anatomy by age, and elimination of operator variability were goals that were accomplished, thereby setting the stage for reliable, reproducible muscle imaging by ultrasound.
