To evaluate the bile duct anatomy of the caudate lobe without disease involvement with use of three-dimensional (3D) cholangiography and to compare the usefulness of this technique with that of rotating cine cholangiography.
In 12 patients with obstructive jaundice but without lesions at the hepatic hilum who underwent percutaneous transhepatic biliary drainage, serial examination was performed with cine cholangiography and helical computed tomography (CT). From helical CT scans, 3D cholangiograms were reconstructed. Cine and 3D cholangiograms were evaluated and compared simultaneously.
In the 12 patients, 40 branches of the caudate lobe were detected with 3D cholangiography (mean, 3.3 branches per patient), while 31 were detected with cine cholangiography (mean, 2.6 branches per patient). The difference in detection rate was significant (P < .01). Nine (23%) of 40 branches were detected with 3D cholangiography alone, and all 31 branches detected with cine cholangiography were also detected with 3D cholangiography.
3D cholangiography was superior to cine cholangiography in assessment of bile duct anatomy of the caudate lobe of the liver because 3D cholangiography eliminated the overlap of different branches of the bile duct.
利用三维（3D）胆管造影术评估未受疾病累及的尾状叶胆管解剖结构，并将该技术的有效性与旋转电影胆管造影术进行比较。
对12例患有梗阻性黄疸但肝门部无病变且接受经皮经肝胆道引流的患者，采用电影胆管造影术和螺旋计算机断层扫描（CT）进行系列检查。从螺旋CT扫描中重建3D胆管造影图像。同时对电影胆管造影图像和3D胆管造影图像进行评估和比较。
在这12例患者中，3D胆管造影术检测到尾状叶分支40支（平均每位患者3.3支），而电影胆管造影术检测到31支（平均每位患者2.6支）。检测率差异具有统计学意义（P <.01）。40支分支中有9支（23%）仅通过3D胆管造影术检测到，电影胆管造影术检测到的所有31支分支也能通过3D胆管造影术检测到。
3D胆管造影术在评估肝脏尾状叶胆管解剖结构方面优于电影胆管造影术，因为3D胆管造影术消除了胆管不同分支的重叠。
