Abstract

The purpose of this study is to compare contrast-enhanced three-dimensional (3D) magnetic resonance (MR) portograms to Doppler sonography in detection of portal venous abnormalities. Thirty-five consecutive patients, who were suspected of having portal venous system abnormalities, were examined with MR portography and Doppler sonography. Vascular abnormalities were identified in 27 of 35 patients. There was statistically significant agreement between the results of MR portography and Doppler sonography. The major limitation of contrast-enhanced 3D MR portography was its inability to provide objective hemodynamic data regarding flow direction and flow pattern.

摘要

本研究的目的是比较对比增强三维（3D）磁共振（MR）门静脉造影与多普勒超声检查在检测门静脉异常方面的效果。连续35例疑似门静脉系统异常的患者接受了MR门静脉造影和多普勒超声检查。35例患者中有27例发现血管异常。MR门静脉造影和多普勒超声检查结果之间存在统计学上的显著一致性。对比增强3D MR门静脉造影的主要局限性在于其无法提供关于血流方向和血流模式的客观血流动力学数据。
