摘要
目的根据常见椎管内肿瘤的MRI表现,对肿瘤定位、定性诊断进行探讨,提高MRI对常见椎管内原发肿瘤的定位定性诊断水平。方法:回顾性分析145例经病理证实的椎管内原发肿瘤的MRI表现。结果髓内肿瘤36例,35例定位诊断正确,25例定性诊断正确;髓外肿瘤109例,106例定位诊断正确,88例定性诊断正确。按解剖隔间定位诊断正确率97.2%,定性诊断正确率77.9%。结论MRI对常见椎管内原发肿瘤的诊断与鉴别诊断有有较高的价值。
Objective To investigate the location and nature diagnosis of intraspi nal odinary tumors according to the results of MRI and pathological basis, and raise the level of MRI location and nature diagnosis of intraspinal odinary tumo rs. Materials and Methods 145 cases of patholigically odinary proven tumors of spine were selected for comparison. Results There were 36 cases spinal cord tu mor,and among them 35 cases were accurate location diagnosed,25 cases were accur ate nature diagnosed.There were 109 cases tumor outside the spinal cord, and amo ng them 106 cases were accurate location diagnosed,88 cases were accurate nature diagnosed. The location accurate rate of intraspinal odinary tumor was 97.2%,a nd The nature accurate rate of intraspinal odinary tumor was 77.9%. Conclusion M RI examination plays an important role in the diagnosis of intraspinal odinary t umor localization and characterization.
