理论与实践：肝转移瘤的手术切除可以延长患者的生存期。切除肿瘤的决定在很大程度上取决于病变相对于肝血管的位置。螺旋计算机断层扫描动脉门静脉造影（SCTAP）是术前定位肿瘤的一种很好的技术。除了三维渲染的图像数据集应提高效率和准确性的解释这些数据由surgeon.METHODS。14例手术和病理证实的孤立性和多发性转移性肝肿瘤进行SCTAP。由此获得的体积数据集被用来通过称为体积绘制的过程产生逼真的三维动画图像。这些图像被提交给外科医生，谁评价他们的基础上，几个criteria.RESULTS.准确和临床有用的图像，在13 14 patients.CONCLUSIONS.临床效用的SCTAP数据集的术前定位肝脏病变的三维渲染已显示回顾性。一个更大的，前瞻性的研究，建议证明该技术的准确性和有效性。
RATIONALE AND OBJECTIVES.Surgical resection of metastatic neoplasms of the liver can prolong survival of patients. The decision to resect a tumor depends to a great extent on the location of lesions relative to hepatic vasculaturc. Spiral computed tomography arterial portography (SCTAP) is an excellent technique for preoperative localization of tumors. The addition of three-dimensional rendering of image data sets should enhance the efficiency and accuracy of the interpretation of these data by the surgeon.METHODS.Fourteen patients with surgically and pathologically proven solitary and multiple mctastatic hepatic neoplasms underwent SCTAP. Volume data sets thus derived were used to produce life-like three-dimensional animated images through a process known as volumetric rendering. These images were presented to the surgeon, who evaluated them based on several criteria.RESULTS.Accurate and clinically useful images were produced routinely in 13 of 14 patients.CONCLUSIONS.Clinical utility of three-dimensional rendering of SCTAP data sets for preoperative localization of hepatic lesions has been shown retrospectively. A larger, prospective study is suggested to demonstrate the accuracy and efficacy of the technique.
