原发性中枢神经系统淋巴瘤的MRI影像诊断特征分析

摘要

Objective To investigate the primary central nervous system lymphoma (PCNSL) of the MRI ef ect of diagnostic characteristics.Methods A retrospective analysis of 25 patients with PCNSL image data,and the patients were fol owed. Results Among the 25 cases of PCNSL were single 37 lesions were found;scan 37 lesions;the tumor body close to the midline andhe median survival period was 8.75 months, the tumor is not close to the midline the median survival period was 15.39 months,the two groups,the dif erence was statistical y significant (P=0.005<0.05).Conclusion Combined with the imaging features of MRI patients,can improve the diagnosis rate of PCNSL.%目的：探讨原发性中枢系统淋巴瘤(PCNSL)的MRI影响诊断特征。方法回顾性分析我院25例PCNSL患者影像资料，并对患者进行随访。结果在25例PCNSL患者共发现病灶37个，其中12例患者位于其大脑半球深部，其余13例患者病灶靠近脑表皮层下；瘤体靠近中线和(或)脑室患者中位生存期为8.75个月，瘤体未靠近中线和(或)脑室患者中位生存期为15.39个月，两组比较，差异具有统计学意义(=0.005<0.05)。结论结合患者MRI影像特征，能够提高对PCNSL的疾病诊断率。
