Abstract:
A method of imaging perfusion of a contrast medium in a first part of a body by means of magnetic resonance (MR) comprising:administering a contrast medium to the body, measuring MR-signals by generating MR perfusion imaging pulse sequences, reconstructing an MR image from the measured MR signals, determining a perfusion MR image from a combination of the MR image and an input function of the contrast medium, wherein the input function is determined by application of an input pulse sequence for the excitation of spins in a second elongated part of the body and by measurement of MR signals from the second part, the second elongated part of the body comprising a part of a vessel transporting a supply of the contrast medium to the first part, a cross section of the second elongated part being oriented such that a contribution from excited spins from the contrast medium in the part of the vessel in the second elongated part dominates a contribution from other excited spins of the second elongated part to the MR signal.
