PURPOSE
To assess the utility of breath-hold abdominal ultrafast three-dimensional (3D) gadolinium-enhanced dual-phase magnetic resonance angiography (MRA).
MATERIAL AND METHODS
125 patients with various abdominal pathologies were imaged using a breath-hold ultrafast gadolinium-enhanced dual-phase 3D-MRA technique.
RESULTS
119 (95%) of 125 MRA's were of good or excellent quality. The sensitivity in the detection of renal artery stenoses as well as stenoses of the celiac trunk and the superior mesenteric artery was 100%. Accessory renal arteries (n = 9) and replaced hepatic arteries (n = 4) were reliably detected by MRA. In 24 (71%) of 34 cases MR-angiographic delineation of the spleno-portal system and hepatic veins was superior compared to conventional angiography.
CONCLUSION
Breath-hold gadolinium-enhanced dual-phase 3D-MRA has the potential to replace conventional angiography in the abdomen.
目的
评估屏气腹部超快三维（3D）钆增强双期磁共振血管造影（MRA）的效用。
材料与方法
使用屏气超快钆增强双期3D-MRA技术对125例患有各种腹部疾病的患者进行成像。
结果
125例MRA中有119例（95%）质量良好或优秀。检测肾动脉狭窄以及腹腔干和肠系膜上动脉狭窄的敏感性为100%。MRA能可靠地检测出副肾动脉（n = 9）和替代肝动脉（n = 4）。在34例中的24例（71%）中，与传统血管造影相比，磁共振血管造影对脾门静脉系统和肝静脉的描绘更优。
结论
屏气钆增强双期3D-MRA有可能取代腹部的传统血管造影。
