At our institution, core muscle biopsies are performed on muscles selected using electromyography (EMG). Ultrasound (US) guidance is not used routinely. The aim of this study was to determine if US guidance of EMG selected muscles would increase the diagnostic yield of the biopsy as compared to the current practice standards.
Two trained physicians performed 40 randomized biopsies (US guided or traditional approach). The amount of tissue obtained in each biopsy was recorded (volume and mass), along with the final pathologic diagnosis in each case and incidence of complications.
Forty patients were studied. Sixteen muscle biopsies were done with US guidance; 50% had a definitive diagnosis, and 38% did not. In the non-US guidance group, 58% had a definitive diagnosis, and 33% did not.
US did not provide any additive advantage when used to guide biopsy in a muscle previously selected for biopsy with EMG. Muscle Nerve 54: 786-788, 2016.
在我们机构，核心肌肉活检是在通过肌电图（EMG）选择的肌肉上进行的。常规不使用超声（US）引导。本研究的目的是确定与当前实践标准相比，超声引导下对肌电图选择的肌肉进行活检是否会提高活检的诊断率。
两名经过培训的医生进行了40次随机活检（超声引导或传统方法）。记录每次活检获取的组织量（体积和质量），以及每个病例的最终病理诊断和并发症发生率。
研究了40例患者。16例肌肉活检在超声引导下进行；50%有明确诊断，38%没有。在非超声引导组中，58%有明确诊断，33%没有。
在用于引导对先前通过肌电图选择进行活检的肌肉进行活检时，超声没有提供任何额外优势。《肌肉与神经》54: 786 - 788, 2016年。
