Abstract:
1. A system for Non-Contrast Agent enhanced MR imaging, comprising: an MR image acquisition device for acquiring over a plurality of heart cycles, first and second datasets representing first and second image slabs individually comprising a plurality of image slices oriented perpendicular in at least one axis to direction of vasculature blood flow, in response to a heart cycle synchronization signal, and within an individual heart cycle a slice of a first image slab and a slice of a second image slab are acquired with one slice of one slab being acquired at a relatively fast blood flow portion of said heart cycle and the other slice of the other slab being acquired at a relatively slow blood flow portion of said heart cycle; an image data processor for processing imaging datasets representing the first and second image slabs to provide first and second volume datasets representing a 3D volume imaged at said relatively fast blood flow portion and said relatively slow blood flow portion respectively and for providing a difference dataset representing an image difference between the first and second volume datasets and enhancing visibility of arterial blood flow; and a display processor for providing data representing an image showing the enhanced arterial blood flow.
