目的评价和探讨脑室内肿瘤的ＣＴ诊断价值。材料与方法收集２５例经ＣＴ诊断并手术病理证实的脑室内肿瘤资料，应用岛津ＳＣＴ—４５００ＴＥ全身ＣＴ机对病变进行薄层、重复和增强扫描，部分图像进行冠矢状面重建。对手术前后的定位和定性诊断进行比较。结果术前定位诊断准确率８８％，定性诊断准确率４８％。结论脑室内肿瘤临床表现不典型，不易早期发现，ＣＴ有较高的定位诊断率，定性诊断可达到５０％。脑室内外肿瘤的鉴别对指导临床手术及预后有重要意义。论著
Objective To evaluate and explore the value of CT in the diagnosis of intraventricular tumors. MATERIALS AND METHODS Twenty-five cases of intracerebral tumor confirmed by CT scan and pathology were collected. Thin-section, repeated and contrast-enhanced MRI were performed with Shimadzu SCT-4500TE whole body CT scanner. Some images were reconstructed with coronal and sagittal planes. Preoperative and postoperative positioning and qualitative diagnosis were compared. Results The accuracy of preoperative localization was 88% and the accuracy of qualitative diagnosis was 48%. Conclusion The clinical manifestations of intracerebral tumors are not typical, not easy to find early, CT has a higher diagnostic rate of localization, qualitative diagnosis can reach 50%. Identification of intracerebral ventricle tumor is of great significance to guide the clinical operation and prognosis. Paper
