Three dimensional imaging of the liver is focused on the spatial visualization of focal lesions in relation to vascular landmarks to support surgical decision making. Additionally the volume estimation of metastases or liver segments is considered in the patient's oncologic follow-up and the planning of the surgical approach. Spiral-CT is destined for 3D imaging, as it represents a standardized, minor invasive, time and cost saving method. Current developments of 3D sonography of the liver are reported. While a special application of 3D imaging, i.e. CT angiography (CTA), replaces preoperative arterial angiography in liver transplantation candidates the diagnostic gold standard for lesion detection still remains by reason of missing algorithms the interpretation of a 2D data set. Validation of 3D versus 2D imaging of the liver demands controlled trials to evaluate the diagnostic potential, time and cost savings of dedicated acquisition techniques, postprocessing algorithms and display modalities.
肝脏的三维成像聚焦于局灶性病变与血管标志的空间可视化,以支持手术决策。此外,在患者的肿瘤随访和手术入路规划中,会考虑转移灶或肝段的体积估计。螺旋CT适用于三维成像,因为它是一种标准化、微创、省时且省钱的方法。本文报道了肝脏三维超声的当前进展。虽然三维成像的一种特殊应用,即CT血管造影(CTA),取代了肝移植候选者术前的动脉血管造影,但由于缺乏二维数据集解释算法,病变检测的诊断金标准仍然是二维成像。肝脏三维与二维成像的验证需要对照试验,以评估专用采集技术、后处理算法和显示方式的诊断潜力、时间和成本节省情况。
