Breath-hold black-blood magnetic resonance imaging of the lung provides promising results in focal lesion detection. Using peripheral pulse gating, we intended to monitor the degree of vascular suppression and the changes in tissue contrast more closely than in the previously reported methods. Black-blood fat-saturated T2-weighted images were acquired for healthy volunteers with incremental delay time points throughout the pulse cycle. The relative ratios of the specific tissue to the muscle were quantified. The systolic phase provided superior black-blood effects and was considered optimal for signal acquisition.
