目的 探讨CT扫描联合MRI在左侧 额颞叶及基底节交界区胶质瘤的诊断分析 价值。方法 回顾性地分析我院2014年1 月-2015年12月期间接收的46例左侧额颞 叶及基底节交界区胶质瘤的检查资料， 通过CT 扫描联合MRI分析胶质瘤的影像 特点，并对胶质瘤的特点进行分析，与 临床特征进行比对。结果 本文共46例患 者，通过CT扫描联合MRI发现胶质瘤，肿 瘤的直井18mm-78mm不等，13例患者影像 资料可见囊实性团状块影，T1WI显示低 信号影，T1WI部分显示弧形高信号影，10 例患者可见左侧额颞叶及基底节交界区病 灶在呈T2WI多发囊性高信号影有分离，12 例患者FLAIR序列病灶出现高信号影，肿 瘤囊壁出现低信号幻影，11例患者可见左 侧占位区皮质脊髓束稀疏，受压移位。结 论 CT扫描联合MRI能反映左侧额颞叶及基 底节交界区胶质瘤的病灶特征、影像信号 特点，不同类型的胶质瘤通过CT扫描联合 MRI，结果和患者的临床病例特征基本吻 合，诊断的准确率达到90%的水平，具有 极高的临床应用价值。

Objective To discuss the CT scanning combined MRI value at the left frontal and temporal lobe and basal ganglia area glioma diagnosis analysis value. Methods From January 2014 to December 2015,our hospital received 46 cases patients with left frontal temporal lobe and basal ganglia glioma border area, Retrospective their inspection of data, through the CT scan combined MRI to observe patients imaging features of glioma, to analyze the characteristics of glioma with clinical features. Results In this paper, we study of 46 patients, through the CT scanning combined MRI find glioma, tumor of vertical Wells 18 mm-78 mm, 13 cases with cystic or solid mass shadow, T1WI low signal in shadow, T1WI inside a few arc high signal shadow, 10 cases is visible on the left side of the frontal and temporal lobe area between the basal ganglia lesions cystic high signal on T2WI in multiple shadow had separated, 12 cases with FLAIR sequence lesions appear high signal, The wall of the tumor in low signal phantom, 11 cases into visible on the left side of the corticospinal tract sparse placeholder area, compressive displacement. Conclusion CT scanning combined MRI could reflect the characteristics of glioma, video signal characteristics about the left frontal temporal lobe and basal ganglia glioma border area .Through CT scanning combined MRI the results of the different types of glioma and clinical features of patients with basic consistent, the diagnostic accuracy rate reached 90%, The research have great value in clinical application.
