In this study, a conversion-free interleaved black blood and bright blood sequence (cfIBBI) is developed for Dynamic Contrast Enhanced (DCE) MRI of vessel wall perfusion of early lesion, which has high spatial resolution and excellent blood suppression in black blood image as well as high temporal resolution in bright blood image for AIF. Moreover, the signal intensities of the black-blood and bright-blood images are comparable and can be used directly in kinetic analysis without conversion.
