| 摘 要： | 目的探讨骨软骨瘤(osteochondroma)的MRI特征。资料与方法回顾性分析经病理证实的16例骨软骨瘤患者的MRI平扫及增强扫描资料,并侧重分析其软骨帽的MRI特征。结果(1)16例骨软骨瘤中,13例有明显软骨帽,软骨帽在T1WI均呈略低信号(与肌肉相比);在T2WI有11例呈明亮高信号,2例呈稍高信号;Gd-DT-PA增强扫描11例呈中等强化,2例轻度强化;(2)13例软骨帽内4例可见明显钙化,T1WI、T2WI均呈低信号。5例儿童和青少年患者的软骨帽厚度为0.8～1.8cm,8例成人患者中,7例软骨帽厚度为0.3～1.1cm,1例软骨帽厚度达3.9cm,均未见恶变;(3)16例中,带蒂型10例,广基型6例(包括鞍底1例、椎板1例);3例软骨帽边缘有软组织肿块。结论软骨帽呈T1WI略低信号,T2WI高信号,Gd-DTPA增强扫描中等强化是典型软骨瘤的MRI特征性表现。 |

| Abstract: | Objective To improve diagnostic accuracy of osteochondroma by studying the MRI features. Materials and Methods Sixteen patients with histologically proved osteochondroma were investigated by MRI (T1-,T2-weighted sequences,intravenous gadolinium application). MRI features of the hyaline cartilage cap were emphatically analyzed. Results (1)13(13/16) cases had hyaline cartilage cap which were a little hypointensity on T1WI(compared with skeletal muscle),meanwhile hyperintensity on T2WI(11 heavy and 2 slight). ... |
