本文回顾性研究了MRI对评价胰腺癌侵犯血管的价值。85例经US或CT引导下穿刺证实为胰腺导管腺癌的患者,32例在US或CT检查中发现属于进展期的病人排除在本研究之外,其余53例中39例位于胰头,11例位于胰体,3例位于胰尾。0.5T超导型MRI扫描机,使用体线圈,层厚7.5mm,间距1mm,采用SET_1加权像及屏气梯度回波序列扫描,注射Gd-DTPA后,分别作屏气梯度回波序列及SET_1加权像扫描,所有病人都作了MRI平扫和增强扫描。在平扫和增强MRI扫描观察肠系膜上血管、腹腔动脉
This article retrospectively studied the value of MRI in evaluating the invasion of blood vessels in pancreatic cancer. Eighty-five patients who underwent US- or CT-guided puncture confirmed pancreatic ductal adenocarcinoma, 32 patients who were advanced in the US or CT examination were excluded from the study, 39 of the remaining 53 were located in the head of the pancreas, 11 The case was located in the pancreas, and 3 cases were located in the pancreas. 0.5T superconducting MRI scanner, using body coil, layer thickness 7.5mm, spacing 1mm, using SET_1 weighted image and breath-hold gradient echo sequence scanning, after Gd-DTPA injection, breath-hold gradient gradient echo sequence and SET_1 weighted image respectively On the scan, all patients underwent MRI scans and enhanced scans. Observation of superior mesenteric and celiac arteries on plain and enhanced MRI scans
