所有参与者均提供了参加本研究的知情同意书，该研究得到了机构审查委员会的批准。在怀疑肾动脉狭窄的患者中，将屏气三维 (3D) 稳态自由进动 (SSFP) 磁共振 (MR) 血管造影与 3D 造影剂增强 MR 血管造影进行比较。两名放射科医生评估了肾动脉的可视化和血管疾病的检测。通过 SSFP MR 血管造影，19 名患者的 41 条肾动脉中的 39 条被正确检测到。通过 SSFP MR 血管造影在两名患者中正确识别了相关狭窄。在两名患者中，SSFP MR 血管造影数据集导致假阳性过度分级或血管疾病。快速屏气 3D SSFP MR 血管造影似乎适用于 MR 血管造影或肾动脉。 (c) 北美放射学会，2006 年。
All participants provided informed consent to participate in this study, which was approved by the institutional review board. Breath-hold three-dimensional (3D) steady-state free precession (SSFP) magnetic resonance (MR) angiography was compared with 3D contrast material-enhanced MR angiography in patients suspected of having renal artery stenosis. Two radiologists assessed visualization or renal arteries and detection of vascular disease. With SSFP MR angiography, 39 of 41 renal arteries in 19 patients were correctly detected. Relevant stenoses were correctly, identified with SSFP MR angiography in two patients. In two patients, SSFP MR angiographic data sets led to false-positive overgrading or vascular disease. Fast breath-hold 3D SSFP MR angiography appears to be feasible for MR angiography, or renal arteries. (c) RSNA, 2006.
