多排螺旋CT多模式重建对腹部巨大肿物的诊断价值

目的：探讨多排螺旋CT（MSCT）多模式重建对腹部巨大肿物定位诊断的应用价值。方法：对14例腹部巨大肿瘤患者的MDCT资料进行回顾性分析,并与手术结果和超声检查结果进行对比。所有病例均行多排螺旋CT全腹部增强扫描,采集的数据在GEAW4.3后处理工作站使用多平面重建（MPR）、最大密度投影（MIP）及容积再现（VR）等技术进行重建。结果：14个病例中,肿瘤最大直径为13.1～32.3cm,平均16.9cm。显示肿瘤血管13例,变异性血管4例,侧支性血供4例,肿瘤染色4例,动静脉早期分流3例。所有病例均可显示局部血管的立体结构以及与周围器官的关系,并可多方位、多角度进行观察。结论：MDCT多模式重建技术作为一种安全无创伤的检查方法,能为临床诊断和治疗,特别是为外科手术制定合理方案等提供有价值的信息。

The value of MSCT multi-model reconstruction in massive occupying lesions in abdomen

Objective：To explore the value localization diagnosis of giant mass in adomen with MSCT multi-model reconstruction.Methods：MSCT data of 14 patients with massive occupying lesions in adomen were analyzed retrospectively,and compared with the results of surgical operation and ultrasonography.All of the patients were underwent contrast en hanced MSCT scan of the whole abdomen.The initial volume data were transferred to the workstation（GE advantage workstation 4.3） and reconstructed with MPR,MIP and VR.Results：Among 14 cases,the diameters of tumor were between 13.1 cm to 32.3 cm with mean 16.9 cm.Tumor vessels in 13 cases,variability blood vessels in 4 cases,lateral branch vessels in 4 cases,tumor staining in 4 cases and arteriovenous shunt in 3 cases were displayed.The stereo-structure of the vessels and their relationship with the surrounding organs were displayed clearly.In addition,the observation could be performed from different angle and positions.Conclusion：As a safe and non-invasive examination method,the multi-slice spiral computed tomography multi-model reconstruction may supply valuable information for the diagnosis and therapy of the diseases,especially surgical operation.
