EXAMINING BLOOD FLOW PATTERNS IN THE BLOOD VESSELS OF A PATIENT USING PHASE CONTRAST MRI

摘要

The invention relates to a technique for examining blood flow patterns in the blood vessels of a patient (1), the technique having the following features: collecting raw data from a time- and space-resolved MRI phase contrast measurement of the cardiovascular system of a patient or parts thereof (1), or reading such data or data determined therefrom via an input interface (3), and calculating at least one primary variable which quantifies the blood flow pattern; carrying out multi-plane reconstructions on the basis of at least one calculated primary variable along a defined path (9) which reproduces the course of a blood vessel of the patient (1) to obtain a local distribution of the at least one primary variable in the vessel cross-section; and calculating and outputting at least one secondary variable which quantifies the blood flow pattern as a function of the position along the course of the vessel on the basis of the at least one primary variable after carrying out the multi-plane reconstructions.
