摘要：

Muscle ultrasound is a useful technique to detect neuromuscular disorders. Quantification of muscle echo intensity (EI) using gray-scale analysis is more reliable and more sensitive compared with visual evaluation of the images. We devised a method to reliably use El normal values established with one ultrasound device for use with another device. Based on measurements in a dedicated phantom and in 7 healthy subjects, a conversion equation was calculated to convert the mean El. The reliability of this equation was next evaluated in a follow-up study of 22 healthy children. Mean muscle El could be reliably converted from one ultrasound device to another. This allows for normal values obtained with one device to be used with other devices, which is an important step forward toward the use of quantitative muscle ultrasound in daily clinical care.
