CONTRAST-ENHANCED MR ANGIOGRAPHY WITH ESTIMATION OF THE FLOW VELOCITY OF THE CONTRAST AGENT

摘要

the invention concerns a procedure for the implementation of a angiographischen measurement of a hauptmessbereich of patients by means of a magnetresonanzanlage and the associated magnetresonanzanlocation and associated computerprogrammprodukt.;the erfindungsgemäße procedures for the implementation of a angiographischen measurement of a hauptmessbereich of patients by means of a magnetresonanzanlage comprises the following steps:carry out at least one übersichtsmessung through the magnetresonanzanlage and übersichtsmessdaten generated- define the hauptmessbereichs and a first measurement range, which is different from hauptmessbereich, via the übersichtsmessdaten,- conduct a first zeitaufgelösten measurement using the magnetresonanzanlage in the established first measurement range, and first time-resolved measurement data are generated.- recording of injected kontrastmittelbolus in the established first measuring range by means of the first zeitaufgelösten measurement data- identify a flow rate of the injected kontrastmittelbolus,- define at least one messparameters the angiographischen measurement in accordance with the calculated flow rate and- implementation of the angiographischen measurement of hauptmessbereichs of patients with the established at least one measures in the magnetresonanzanlage.
