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.
