摘　　要：目的分析不同CT成像方法在脑胶质瘤边界确定中的差异性。方法分析2012年6月~2016年12月于我院就诊的43例脑胶质瘤患者的CT灌注与普通增强CT的数据资料,根据所获得的图像分别勾勒并测量脑胶质瘤面积,比较两种成像方法所获得的病灶截面面积。结果术前胶质瘤患者CT灌注成像中胶质瘤勾勒的面积为(11.63±2.25)cm^2,明显大于常规增强CT中胶质瘤勾勒的面积(10.06±2.13)cm^2,差异具有统计学意义(P<0.05);术后残留或复发患者中CT灌注成像中胶质瘤勾勒的面积为(11.14±2.12)cm^2,明显大于常规增强CT中胶质瘤勾勒的面积(9.78±2.03)cm^2,差异具有统计学意义(P<0.05)。结论 CT灌注成像所确定的肿瘤范围更能反映出胶质瘤的浸润范围,有助于指导胶质瘤的治疗,值得在临床上推广。Objective To analyze the difference of different CT imaging methods in the determination of brain glioma boundary. Methods The data of CT perfusion and generally enhanced CT in 43 patients with brain glioma who were admitted to our hospital from June 2012 to December 2016 were analyzed. According to the obtained images, the brain glioma area was outlined and measured. The obtained lesion cross-sectional area was compared between the two imag- ing methods. Results The outlined area of glioma in CT perfusion imaging was （11.63±2.25） cm^2 in preoperative glioma patients, significantly higher than that of （10.06±2.13） cm^2 in conventional enhanced CT, the difference was Statistically significant （P〈0.05）; the outlined area of glioma in CT perfusion imaging was （11.14±2.12） cm^2 in postoperative residual or relapsed patients, significantly higher than that of （9.78±2.03）cm^2 in the conventional enhanced CT, the difference was statistically significant（P〈0.05）. Conclusion The range of tumor determined by CT perfusion imaging can reflect the infiltration range of glioma, and it can help to guide the treatment of glioma, which is worthy to be popularized in clinical practice.
