摘要
目的:研究超薄层CT数据数字化在腹膜后肿瘤的临床应用价值。方法:收集腹膜后肿瘤患者并给予口服造影剂,加压腹部等扫描前准备,行超薄层CT增强扫描,将超薄层CT数据传至工作站进行三期数据的配准,宽窗、宽位选择,三维分割重建及数字化处理。结果:超薄层数字化模型可三维显示腹膜后肿瘤位置、大小,同时显示肿瘤与腹膜后相邻器官的关系,尤其是肿瘤与下腔静脉、脾脏血管及胰腺的关系。结论:腹膜后肿瘤患者超薄层CT数据通过数字化处理,有助于了解腹膜后肿瘤的解剖关系、术前规划及术前评估,具有一定的临床及科研意义。
Objective： To study the clinical value of data digitization of ultrathin layer CT in retroperitoneal tumor. Methods： Ultra thin CT scan data will be collected for patients with retroperitoneal tumor. They will be given oral contrast agent before scanning. Then the thin layer CT data were transmitted to the workstation for three data registration, wide window, wide selection, 3D reconstruction and segmentation of digital processing. Results： Ultrathin layer digital model can display the location of retroperitoneal tumor in three dimensions, and show the relationship between tumor and adjacent organs at the same time, especially the relationship between tumor and inferior vena cava, splenic vessels and pancreas. Conclusion： The digital processing of ultrathin layer CT data in patients with retroperitoneal tumor helps to understand the anatomical relationship, preoperative planning and preoperative assessment of retroperitoneal tumors. It has certain clinical and scientific significance.
