Successful management of the idiopathic inflammatory myopathies requires an early and accurate diagnosis. The muscle biopsy remains the definitive test. However, false-negative biopsy results are common, as the disease is typically patchy in distribution. The advent of short tau inversion recovery sequences now allows rapid magnetic resonance imaging of the whole body to be performed, enabling identification of the muscles most suitable for biopsy. It also provides further diagnostic information through the form and anatomic distribution of the pathology. We report 2 cases illustrating the advantages of whole-body short tau inversion recovery magnetic resonance imaging before muscle biopsy. We encourage clinicians to use the technique in this context.
特发性炎性肌病的成功管理需要早期准确诊断。肌肉活检仍是确诊检查。然而，活检结果假阴性很常见，因为该病通常呈斑片状分布。短tau反转恢复序列的出现使得现在能够对全身进行快速磁共振成像，从而能够识别最适合活检的肌肉。它还通过病理的形态和解剖分布提供进一步的诊断信息。我们报告2例病例，说明肌肉活检前全身短tau反转恢复磁共振成像的优势。我们鼓励临床医生在此情况下使用该技术。
