Over the last decade MR imaging has gained widespread acceptance as the modality of choice for initial evaluation of a soft tissue mass. Although MR imaging generally does not predict the histologic nature of a mass, significant data are accumulating on MR imaging features useful in the diagnosis of several benign conditions and a few malignant ones. Soft tissue masses that do not demonstrate tumor-specific features on MR imaging should be considered indeterminate and possibly malignant and a biopsy should be obtained. This article reviews the literature and elaborates on soft tissue conditions where MR imaging features can suggest an accurate diagnosis of a soft tissue mass. The article also reviews other important applications of MR imaging as well as recent developments in pulsing sequences and MR spectroscopy. The major series studying the diagnostic value of MR imaging in soft tissue masses is discussed and compared.
在过去十年中，磁共振成像（MR成像）作为软组织肿块初始评估的首选方式已得到广泛认可。尽管MR成像通常无法预测肿块的组织学性质，但关于其在几种良性疾病和少数恶性疾病诊断中有用的成像特征的数据正在大量积累。在MR成像上未表现出肿瘤特异性特征的软组织肿块应被视为不确定且可能为恶性，应进行活检。本文回顾了相关文献，并详细阐述了MR成像特征可提示软组织肿块准确诊断的软组织疾病。本文还回顾了MR成像的其他重要应用以及脉冲序列和磁共振波谱的最新进展。讨论并比较了研究MR成像在软组织肿块诊断价值的主要系列研究。
