摘　　要：胆道梗阻性疾病的术前诊断主要依赖于影像学检查，且检查结果直接关系到临床疗效及患者预后。PTC是胆道梗阻性病变最常用的检查方法。在PTC基础上进行CT检查可提高胆道梗阻性病变的检出率¨0。近年来多层螺旋cT的广泛应用，尤其是图像后处理技术和软件的开发，为FFC＋CT检查创造了条件。2009年4月至2011年4月我院采用PTC＋CT检查诊断胆道梗阻性疾病8例，取得了较满意的效果。Preoperative diagnosis of biliary obstruction mainly depends on imaging examination. Percutaneous transhe- patic cholangiography （PTC） is a common method in detecting bilialy obstruction. PTC combined with computed tomography （CT） could enhance the diagnostic rate. From April 2009 to April 2011, 8 patients with bilia1~~ obstruction were admitted to the Shenzhen Hospital of Peking University. Contrast solution （30 ml of iodine solution at a concentration of 1.5% -2.0% ） was injec- ted through a PTC tube, and then CT scan was performed. An iohexol contrast solution at a concentration of 300 mgI/ml was injected at a dosage of 1.5 ml/kg and at 3-5 ml/s, then the arterial phase, venous phase and delayed phase were scanned. The original data were uploaded to Vitrea 2 workstation for muhi- plane reconstruction, maximum intensity projection and volume rendering. The procedure was successfully performed on all patients, and the position of the biliary obstruction was identified in 7 patients. Five patients were diagnosed as with hilar cholan- giocarcinoma, 1 with sclerosing cholangitis and 2 with adenoma of the distal common bile duct. The patients＇ symptoms were alleviated after percutaneous transhepatic biliary drainage.
