System for non-contrast enhanced MR anatomical imaging

摘要

A system for Non-Contrast Agent enhanced MR imaging, includes an MR image acquisition device that acquires first and second datasets representing first and second image slabs individually comprising multiple image slices acquired at fast and slow blood flow portions of a heart cycle and oriented substantially perpendicular in at least one axis to direction of vasculature blood flow, in response to a heart cycle synchronization signal. An image data processor processes imaging datasets representing the first and second image slabs to provide first and second volume datasets representing a 3D volume imaged at the fast blood flow portion and the slow blood flow portion respectively and for providing a difference dataset representing an image difference between the first and second volume datasets and enhancing arterial blood flow. A display processor provides data representing an image showing the enhanced arterial blood flow.

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.
