摘要： 目的探讨多层CT重建图像显示颅内异物的临床意义。方法16例颅内异物患者全部行16层CT薄层扫描,利用工作站进行三维重建和多平面重建(MPR),5例颅内异物患者行CT血管造影(CTA)检查,将异物显示情况与手术结果对照。结果异物位于一个脑叶11例、贯穿两个脑叶以上3例、脑室内2例,其中接近颅底者6例(包括接近颅底动脉环2例);14例患者手术摘除异物18枚,重建图像与术中结果对照定位准确率100%,定性准确率85.7%。结论多层CT重建图像可从多角度显示颅内异物,有利于临床医生术前了解异物的性质、位置、整体走向,制定最佳手术方案。

Abstract: ObjectiveTo evaluate the role of multi-slice CT(MSCT) reconstruction in the diagnosis of intracranial foreign bodies.MethodsMSCT scans were performed in 16 patients with intracranial foreign bodies. The volumetric data were reconstructed in the workstation. 5 patients were detected by CT angiography (CTA) examination. Imaging results were then compared with findings found during surgery.Results11 foreign bodies located in one brain lobe, 3 passed two brain lobes, 2 located in ventricle. Among them, 6 cases were closed to parietal including 2 cases closed to cerebral arterial circle. 14 patients were operated and extirpated 18 foreign bodies. Compared with surgical findings, the orientative accuracy of reconstruction imaging was 100%, qualitative accuracy was 85.7%.ConclusionMSCT reconstruction may display the intracranial foreign bodies from multi-angles. It is propitious to know the characteristics, location and whole shape of the foreign bodies for the surgeon before the operation, accordingly to make a best operation project.
