软组织良恶性肿瘤的CT鉴别诊断

CT Differential Diagnosis of Benign and Malignant Soft Tissue Tumors

目的探讨CT鉴别软组织良恶性肿瘤的价值。资料与方法搜集经手术或穿刺活检病理证实的40例软组织肿瘤患者的CT资料,对肿瘤大小、形态、边界、密度及其与周围组织的关系进行回顾性CT影像分析,并探讨这些征象在鉴别诊断中的价值。结果18例良性肿瘤和18例恶性肿瘤通过CT征象可以做出正确的良恶性鉴别诊断。结论CT能明确软组织肿瘤的特征、范围以及肿瘤与周围组织的关系,在软组织良恶性肿瘤的鉴别诊断中有重要的价值。

Objective To discuss the value of MRI in diagnosis of the rhabdomyolysis.Materials and Methods The MRI findings and clinic characteristic of 12 cases with rhabdomyolysis confirmed by MRI and clinic were analyzed retrospectively.Results The location number of the cases was in mesoglutaeus,in ectogluteus,in extremities muscle was 5,3,4 respectively.7 cases were depicted as slight hyperintensity signal on T2WI and T1WI slightly hypointensity or isointensity signal on T1WI.All the cases had hyperintensity signal on T2WI fat-suppressed sequence.Different level lamellar or patch enhancement was showed on enhanced MR.Course of feeding artery in lesion was nature in 5 cases.Conclusion The location and range of rhabdomyolysis are depicted clearly by MRI,MR has some significance on guiding the early diagnosis,early treatment and precaution complication of rhabdomyolysis.
