The use of carbon dioxide in magnetic resonance angiography: a new type of black blood imaging.
The injection of boluses of carbon dioxide (CO(2)) during T1-weighted magnetic resonance angiography (MRA) resulted in sharp depiction of the vascular lumen during the performance of in vitro and in vivo animal experiments. We propose the use of the low-cost, relatively safe CO(2) as a negative contrast agent for MRA and speculate on its use in future interventional MRA.
