MRI与CT对原发性脑淋巴瘤的诊断价值分析

Analysis of Diagnostic Value of CT and MRI for Primary Cerebral Lymphoma

目的探讨MRI与CT对原发性脑淋巴瘤的诊断价值。方法选取50例原发性的脑淋巴瘤患者作为观察组,选50例颅内发生转移的瘤患者作为对照组,行MRI和CT检查,比较患者的病灶分布、肿瘤囊变及坏死和水肿情况、信号特点及尖突症情况。结果患者病灶多分在深部的脑组织,呈区域性分布,瘤周围以中度水肿为主,较少出现囊变及坏死,T2W1主要为等或者低信号,尖突多呈阳性。结论 MRI和CT检查能够提高原发性淋巴瘤患者诊断率,有助于其早期诊断。

Objective To research the diagnostic value of CT and MRI for primary cerebral Lymphoma. Methods 50 cases of primary cerebral Lymphoma were the observation group,and 50 cases of intracranial metastatic tumor were the control group. MRI and CT examination was conducted,the lesions distribution,tumor SAC variable,necrosis,edema of situation,signal features and pointed bursting syndrome situation were compared. Results The lesions were mainly in the deep part of the brain tissues,and had regional distribution. The tumor was dominated by moderate edema,and seldom had necrosis and cystic degeneration,T2W1 were mainly medium and low signal,cusp showed positive. Conclusion MRI and CT findings can improve the diagnosis rate of primary lymphoma,it can contribute to the early diagnosis.
