摘　　要：目的　了解MRI对软组织非特异性炎性病变的诊断能力。方法　分析 15个病变的部位、MR信号特征。结果　面部 1例 ,后颈部和臀部各 2例 ,腰背部 3例 ,大腿 7例。 4例未形成脓肿 ,11例形成脓肿。充血水肿区在T1WI呈较低信号 ,T2 WI呈较高信号 ,其信号强度随病变向周围扩展而逐渐降低并过度至正常结构。无脓肿或以充血水肿区为主时 ,原组织结构轮廓可以辨认。10例行增强扫描 ,充血水肿区、脓肿壁和脓肿间隔均有显著强化。结论　MRI可以显示软组织非特异性炎性病变的部位及范围 。Objective To evaluate the efficacy of MRI in diagnosing the non-specific inflammation in soft tissue.Methods The following MR features of 15 lesions,including the location and signal et al,were analysed retrospectively.Results The lesions were located in face(1 case),scruff (2 cases),hip(2 cases),back(3 cases),and thigh(7 cases),respectively.Abscesses occurred in 11 cases whereas the others didn′t.The areas of hyperaemia and edema demonstrated as relatively low signal on T 1WI and relatively high signal on T 2WI,furthermore,the signal intensities of them reduced gradually to the normal with their extension to the outsides.The original tissue configurations could be identified when there were no abcesses or the lesions were consisted mainly by the areas of hyperaemia and edema.The enhenced MR imaging were scanned in 10 cases in which enhencement occurred in all of them.Conclusion The location and area of the non-specific inflammation in soft tissue can be demonstrated and the nature of them can be further diagnosed.
