摘　　要：目的分析MR检查SWI序列在鉴别颅内淋巴瘤、高级别胶质瘤中的临床意义。方法回顾收集2017年2月至2019年10月来我院经过病理活检确诊的颅内淋巴瘤(15例)、高级别胶质瘤(28例)患者临床资料,对两类肿瘤患者常规MR图像及SWI图像进行分析。观察不同疾病患者影像学表现特征。结果例颅内淋巴瘤患者常规MR扫描见病灶边界清晰的类圆形或不规则形,T1WI及T2WI序列上分别呈稍低信号、稍高信号。3个病灶可见短T1或短T2斑、点及片状出血信号,SWI序列上,4个病灶呈斑、点及片状高信号。28例高级别胶质瘤常规MR扫描见病灶边界模糊的类圆形或不规则形,T1WI及T2WI序列上分别呈低信号、高信号,9个病灶可见短T1或短T2斑、点及片状出血信号,SWI序列上,有37个病灶呈斑、点及片状高出血信号。.常规MRI、SWI序列对出血灶检出率无明显差异(P>0.05)。常规.MRI序列对出血灶检出率低于SWI序列(1731%vs7115%),在SWI序.列高级别胶质瘤出血率检出率高于颅内淋巴瘤(P<005);SWI序列上高级别胶.质瘤1分、2分出血量评分例数高于颅内淋巴瘤(P<005)。结论MR检查SWI序列可有效显示颅内淋巴瘤、高级别胶质瘤信号特征,通过观察出血评分,可为疾病鉴别提供可靠信息。Objective To analyze the clinical significance of sWI sequence of MR examination in identifying intracranial lymphoma from high-grade glioma. Methods The clinical data of patients with intracranial lymphoma(15 cases) or high-grade glioma(28 cases) diagnosed by pathological biopsy in our hospital from February 2017 to October 2019 were retrospectively collected. The conventional MR images and s WI images of patients were analyzed. The imaging characteristics of patients with different diseases were observed. Results In 15 patients with intracranial lymphoma, the conventional MR scan showed a clear, round or irregular boundary of the lesions. The T;WI and T;WI sequences showed slightly lower and slightly higher signals, respectively.short T;or short T;spotted, and patchy bleeding signals were seen in 3 lesions. In the s WI sequence, the four lesions showed speckled and patchy high signals. Conventional MR scans of 28 cases with high-grade gliomas showed round or irregular shapes with blurred boundaries. T;WI and T;WI sequences showed low signal and high signal, respectively. Nine lesions showed short T;or short T;spotted, and patchy bleeding signals. In the s WI sequence, 37 lesions showed spotted, and patchy bleeding signals. There was no significant difference in the detection rate of bleeding lesions bewteen conventional MRI and s WI sequences(P>0.05). The detection rate of bleeding lesions by conventional MRI sequence is lower than that by s WI sequence(17.31% vs 71.15%), and the detection rate of bleeding of high-grade glioma by the s WI sequence was higher than that of intracranial lymphoma(P<0.05). In the s WI sequence, the number of high-grade gliomas with 1 or 2 score was higher than that of intracranial lymphoma(P<0.05). Conclusion MR examination of s WI sequence can effectively display intracranial lymphoma and high-grade glioma signal characteristics, and the bleeding score can provide reliable information for identification of disease.
