目标
在三维肝脏肿瘤 CT 成像中添加动态对比。
材料和方法
该研究纳入了 6 名平均年龄为 57 岁的肝海绵状血管瘤患者。其中两名患者为男性，四名患者为女性。采用螺旋CT对肿瘤进行六期造影增强计算机断层扫描(CT)，静脉推注造影剂。使用最大强度投影 (MIP)，为每个阶段重建单独的三维图像，并使用 CRT 监视器观察围绕躯干纵轴的旋转图像。
结果
在 3D 图像上获得肝海绵状血管瘤的对比度增强模式。在所有患者中，肿瘤与门静脉和肝静脉之间的相互关系均清晰地三维成像。
结论
我们成功地将造影剂的动态观察添加到静态三维成像中。这对于肝脏肿瘤的诊断具有重要价值，并为诊断成像开辟了新的前景。
OBJECTIVE
Addition of contrast dynamics to three-dimensional hepatic tumor CT imaging.
MATERIALS AND METHODS
Six patients with hepatic cavernous hemangioma with a mean age of 57 years were included in the study. Two of the patients were male and four were female. Contrast enhanced computed tomography (CT) was carried out on the tumors in six phases by helical CT, using bolus injection of contrast medium intravenously. Using maximum intensity projection (MIP), a separate three-dimensional image was then reconstructed for each phase, and rotational images around the longitudinal axis of the torso were observed using the CRT monitor.
RESULTS
The patterns of contrast enhancement of hepatic cavernous hemangiomas were obtained on 3D-images. In all patients, the reciprocal relations between the tumor and the portal veins and the hepatic veins were clearly imaged three-dimensionally.
CONCLUSIONS
We have succeeded in adding the dynamic observation of a contrast medium to static three-dimensional imaging. This will be valuable for the diagnosis of hepatic tumors, and it opens up new prospects for diagnostic imaging.
