摘　　要：目的探究脑胶质瘤术前诊断中CT与MRI的应用价值。方法此次研究对象选自本院及河南科技大学第一附属医院2018年12月至2022年3月期间收治的50例脑胶质瘤患者,所有患者全部进行CT与MRI扫描检查,分析两种诊断手段的结果。结果CT检查中,15例病灶单纯低密度影、25例混杂密度影、10例高密度影,6例合并钙化。星形细胞瘤患者中,8例无明显强化,16例明显强化,环状强化特征8例,环壁厚薄不均匀,合并囊变液化坏死低密度区,单纯实质斑片状增强3例,病灶花环状强化、斑片状或毛细血管纹状强化发生于实质期5例;MRI检查中,星形细胞瘤低信号或者等信号存于T1WI序列,高信号存于T2WI序列。增强扫描中无显著强化图像表现2例,4例斑片状明显强化、8例片状轻中度强化、10例不均匀斑点强化。在胶质母细胞瘤低信号存于T1WI序列,高信号存于T2WI序列,有明显水肿存于病灶周边。增强扫描中,有花环状明显强化特征,胼胝体受累患者较多,纵裂池出现变形情况。少突胶质细胞瘤低信号存于T1WI序列,高信号存于T2WI序列,有明显钙化灶和囊性改变出现于病灶,并发生中轻度水肿,增强扫描后,出现线条样和斑点样中轻度强化特征。MRI联合CT诊断脑胶质瘤的特异度和灵敏度显著高于单独应用CT、MRI(P<0.05)。结论脑胶质瘤应用MRI联合CT进行检查的特异度和灵敏度较高,可通过病灶图像表现特征、病灶累计范围制定手术方案。Objective To explore the application value of CT and MRI in the preoperative diagnosis of glioma.Methods The study subjects were all selected from 50 glioma patients admitted to our hospital and the First Affiliated Hospital of Henan University of Science and Technology from December 2018 to March 2022.All patients underwent CT and MRI scans,and the results of the two diagnostic methods were analyzed.Results In the CT examination,15 cases of lesions were simple low-density shadows,25 cases of mixed density shadows,10 cases of high-density shadows,and 3 cases with calcification.Among patients with astrocytoma,8 cases had no obvious enhancement,and 16 cases had obvious enhancement.8 cases were characterized by ring enhancement,The thickness of the annular wall is uneven,with cystic liquefaction and necrosis in the low-density area,3 cases of simple parenchymal patchy enhancement,and 5 cases of rosette enhancement,patchy or capillary striated enhancement occurred in parenchymal phase;MRI examination,star The low signal or equal signal of cell tumor is stored in the T1WI sequence,and the high signal is stored in the T2WI sequence.In the enhanced scan,there was no significant enhancement of the image in 2 cases,4 cases of patchy obvious enhancement,8 cases of patchy mild to moderate enhancement,and 10 cases of uneven spot enhancement.In glioblastoma,the low signal is stored in the T1WI sequence,the high signal is stored in the T2WI sequence,and there is obvious edema around the lesion.In the enhanced scan,there are obvious enhancement features of flower ring,more patients with corpus callosum involvement,and deformation of the longitudinal fissure pool.The low signal of Oligodendroglioma is stored in the T1WI sequence,and the high signal is stored in the T2WI sequence.There are obvious calcification and cystic changes in the lesion,and moderate to mild edema.After enhanced scanning,there are lines and spots with moderate to mild Strengthen features.The specificity and sensitivity of CT in diagnosing glioma were signif
