Methods for achieving suppression of blood pool signal to image contrast-enhanced organs and vascular walls using magnetic resonance (MR) imaging technology. After administration of e.g., an intravenous contrast agent, an RF pulse sequence is applied that includes a preparatory section designed to modify signal from organ tissue differently than blood pool signal, followed by an inversion RF pulse. MR signals are then allowed to evolve during a wait time that is sufficiently long to permit tissue species with dissimilar T1 relaxation times to separate in signal yet short enough so that blood signal has greater negative magnetization than other tissues of interest. MRI data is then acquired with phase sensitive reconstruction so that blood pool signal is suppressed compared with the tissues of interest.
