Emerging new techniques for liver resections set new requirements for the preoperative imaging and planning. Open surgery is a three-dimensional procedure and planning of the resection line may be difficult when basing on conventional two-dimensional CTs or MRIs, although all the information is there. With multidetector-row CT (MDCT), thin slices can be obtained with excellent temporal resolution, and precise three-dimensional (3D) models can be created. We regard 3D imaging technique useful in most liver resections. It improves the surgeon's knowledge of liver anatomy and makes even more complicated liver resections safe. Better knowledge of three-dimensional appearances of liver structures may further improve the results of curative liver surgery. However, before becoming a routine clinical procedure, research and development are still needed. Also, careful testing and evaluation of the methods have to be performed. In the future, 3D models will probably play an important role in the preoperative planning of liver resections.
肝脏切除术的新兴技术对术前成像和规划提出了新要求。开放手术是一种三维操作，尽管所有信息都存在，但基于传统二维CT或MRI来规划切除线可能会很困难。使用多排探测器CT（MDCT），可以获得具有出色时间分辨率的薄层扫描，并创建精确的三维（3D）模型。我们认为3D成像技术在大多数肝脏切除术中都很有用。它提高了外科医生对肝脏解剖结构的了解，使更为复杂的肝脏切除术变得安全。对肝脏结构三维外观的更好了解可能会进一步改善根治性肝脏手术的效果。然而，在成为常规临床操作之前，仍需要进行研发。此外，必须对这些方法进行仔细的测试和评估。未来，3D模型可能会在肝脏切除术的术前规划中发挥重要作用。
