Gadolinium-enhanced, three-dimensional, breath-hold magnetic resonance (MR) coronary angiography was performed in two healthy volunteers and 11 patients suspected or known to have coronary artery disease. MR angiograms were compared with those obtained with retrospective respiratory gating. Of 52 main coronary arteries, 47 could be visualized with the breath-hold technique and 49 with the gating technique. Signal-to-noise and contrast-to-noise ratios were significantly higher with the breath-hold technique. Overall image quality was slightly lower with breath-hold imaging. With either technique, three of five, significant coronary stenoses were correctly identified.
对两名健康志愿者以及11名疑似或已知患有冠状动脉疾病的患者进行了钆增强三维屏气磁共振（MR）冠状动脉造影。将磁共振血管造影与通过回顾性呼吸门控获得的造影进行比较。在52条主要冠状动脉中，屏气技术可显示47条，门控技术可显示49条。屏气技术的信噪比和对比噪声比显著更高。屏气成像的整体图像质量略低。无论采用哪种技术，5处严重冠状动脉狭窄中有3处被正确识别。
