MR tomography is a useful procedure for assessing changes in size and structure of skeletal muscles in three dimensions. It provides excellent soft tissue contrast resolution, but spatial resolution requires to be improved. Myatrophic alterations can be shown best by using short echo delay times (TE) and short repetition times (TR). Muscles with fatty degeneration reveal a change in signal intensity and in relaxation times. These reproducible MR findings indicate appropriate areas of EMG diagnosis and biopsy and provide objective follow-ups.
磁共振断层扫描是一种用于在三维空间评估骨骼肌大小和结构变化的有用方法。它提供了出色的软组织对比分辨率，但空间分辨率有待提高。通过使用短回波延迟时间（TE）和短重复时间（TR），可最佳显示肌萎缩性改变。脂肪变性的肌肉在信号强度和弛豫时间上会出现变化。这些可重复的磁共振成像结果为肌电图诊断和活检指明了合适的区域，并提供了客观的随访依据。
