MR imaging is the ideal technique to display the soft-tissue abnormalities produced by infectious processes. In general these soft-tissue alterations consist of signal intensity changes that reflect the increased water content of the soft tissues induced by the inflammatory reactions. In some cases these changes are nonspecific, but in others, MR imaging can be quite specific and helpful in detecting the presence and extent of the infection, which generally is suspected clinically on the basis of physical and laboratory findings. The MR manifestations of soft-tissue infection, including septic arthritis, tenosynovitis, bursitis, cellulitis, necrotizing fascitis, soft-tissue abscess, infectious myositis, HIV-related infection, lymphadenitis and lymphangitis, and a few unusual parasitic and fungal infections, are reviewed.
磁共振成像（MR）是显示感染性疾病所致软组织异常的理想技术。一般来说，这些软组织改变表现为信号强度变化，反映了炎症反应引起的软组织含水量增加。在某些情况下，这些变化是非特异性的，但在其他情况下，MR成像可能具有很高的特异性，有助于检测感染的存在及范围，临床上通常根据体格检查和实验室检查结果怀疑有感染。本文综述了软组织感染的MR表现，包括化脓性关节炎、腱鞘炎、滑囊炎、蜂窝织炎、坏死性筋膜炎、软组织脓肿、感染性肌炎、HIV相关感染、淋巴结炎和淋巴管炎，以及一些罕见的寄生虫和真菌感染。
