The value of multiplanar reconstruction (MR) in coronal and sagittal planes from axial transverse computed tomography (CT) slices was investigated in cases of obstructive jaundice. The clinical application for this technique lies in its potential to depict the dilated bile duct to the point of obstruction providing a "map" of the biliary tree. We call the technique "CT cholangiography." The images obtained were of good quality in 77.5% of the cases. Coronal planes proved better than sagittal in demonstrating the bile duct. Furthermore, MR added information concerning the cause of obstruction in 27% of the cases. Improvements in technique will refine the method and likely eliminate the need for invasive cholangiography in many cases of obstructive jaundice.
在梗阻性黄疸病例中，研究了从轴向横断计算机断层扫描（CT）切片进行冠状面和矢状面多平面重建（MR）的价值。该技术的临床应用在于其能够描绘出扩张的胆管直至梗阻点，从而提供胆管树的“地图”。我们将该技术称为“CT胆管造影”。在77.5%的病例中获得的图像质量良好。在显示胆管方面，冠状面被证明优于矢状面。此外，在27%的病例中，多平面重建增加了有关梗阻原因的信息。技术的改进将完善该方法，并可能在许多梗阻性黄疸病例中消除侵入性胆管造影的必要性。
