目的:研究幕上及幕下脑室内中枢神经细胞瘤的CT及MRI影像学表现。方法:选取2010年8月至2015年6月期间我院收治的39例中枢神经细胞瘤患者,使用GE Highspeed CT/i,对所有患者进行CT平扫;使用GE signa Twinspeed 1.5 T超导磁共振扫描仪,对所有患者进行MRI平扫,观察39例中枢神经细胞瘤患者幕上及幕下脑室中肿瘤的具体位置、大小、形态,对比CT检查的表现与MRI检查的表现。结果:在39例中枢神经细胞瘤患者中,13例位于右侧侧脑室,9例位于左侧侧脑室,11例患者的双侧侧脑室皆有肿瘤,另外6例患者的双侧侧脑室及三脑室皆有肿瘤;39例患者的肿瘤平均大小为52 mm;36例呈不规则分叶状,3例肿瘤边界模糊;部分肿瘤存在不同程度的钙化现象。结论:中枢神经细胞瘤的影像学表现的部位及特征性较为典型,通过CT扫描以及MRI扫描,均能有效地检出中枢神经细胞瘤,而MRI影像学检查,能够有效地提高对中枢神经细胞瘤的诊断准确率,检查结果优于CT检查。
Objective: To study CT and MRI findings of supratentorial and infratentorial mediastinal neuroblastoma. Methods: Thirty-nine patients with central neurocytoma admitted to our hospital from August 2010 to June 2015 were enrolled in this study. All patients underwent CT scan with GE Highspeed CT / i. Using GE signa Twinspeed 1.5 T superconducting magnetic resonance Scanner, MRI scan of all patients to observe the location of the tumor in the supratentorial and supratentorial space of 39 patients with central neurocytoma, the size, shape, CT contrast and MRI findings. Results: Of the 39 patients with central neurocytoma, 13 were located in the right lateral ventricle and 9 in the left lateral ventricle. Eleven patients had tumors in bilateral lateral ventricles. The other 6 patients had bilateral lateral ventricles and All three patients had tumors. The average size of tumor in 39 patients was 52 mm. 36 patients showed irregular lobulation. The borderline of 3 tumors was blurred. Some tumors had calcifications. CONCLUSIONS: The imaging features and features of central neurocytoma are typical. CT scan and MRI scan can effectively detect central neurocytoma, and MRI imaging can effectively improve the central nervous system cells The diagnostic accuracy of the tumor, the test result is better than the CT examination.
