64排電腦斷層使用Curved Planar Reformation對於十二指腸壺腹附近病灶的偵測
Detection of Periampulla of Vater Lesions Using 64-MDCT Curved Planar Reformation Technique
摘要
本研究的主要目的，是針對十二指腸壺腹附近電腦斷層影像，利用影像處理工作站中之Curved Planar Reformation的技術來評估其臨床上的意義。從94年7月至96年2月共收集了15位患者，其中有9位接受外科手術。病理報告分別爲十二指腸壺腹腫瘤(Ampulla of Vater tumor)、胃與腸的基質瘤(GIST)、是十二指腸腺癌及胰臟癌，而其中2位分別爲膽管癌及胃癌，這2位並不在本研究範圍內，因此最後只剩下7位（男性5位，女性2位，年齡分佈從40歲至94歲，平均62歲）。選擇第二組(Late arterial phase)與第三組(Portal venous phase)的影像做Curved Planar Reformation，結果發現此影像處理技術可提供總膽管(CBD)、十二指腸壺腹(Ampulla of Vater)及胰管(Pancreatic duct)的路徑在同一2D影像上，以及腫瘤對於血管、周邊組織或器官侵犯的程度與癌的分期，對於臨床醫師評估患者的治療方式是一大助益。

The main purpose of this study is to determine the clinical significant of curved planar reformation technique in detecting periampullary lesions. From July 2004 through February 2006, we collected 15 patients who underwent CT-scan study using 64-MDCT. Nine out of 15 cases received surgical interventions with pathological findings of ampulla of Vater tumor, gastrointestinal stromal tumor, duodenal carcinoma pancreatic head cancer, cholangiocarcinoma and gastric cancer. Patients population include 5 male and 2 female age ranges from 40 to 94 with mean age of 62 year old. We analyzed the late arterial phase and the portal venous phase using a curved planar reformation at the advantage workstation GE VCT 64-MDCT. This study showed the feasibility to demonstrate the common bile duct, pancreatic duct, and the periampulla of Vater region. It can also visualized the presence of tumor invasion to the adjacent vessels or other structures. We therefore conclude that this technique can help much for periampullary tumor staging and probably avoiding a more invasive procedure such as ERCP.
