Method of and device for imaging an object by means of magnetic resonance

A device for magnetic resonance (MR) imaging of a part of a body of a human or animal arranged in the device comprising:

• means for administering a supply of contrast agent to image said part of said body;
• means for generating a steady magnetic field,
• means for generating RF pulses,
• means for generating gradients in the steady magnetic field,
• means for measuring MR signals,
• means for reconstructing an MR image from the measured MR signals,
• means for determining information for determining an input function of a contrast medium in a part of a vessel transporting the contrast medium to a first part of the body,
• a control unit for generating control signals for said means for generating RF pulses and said means for generating the gradients,
• means for determining the input function from the information determined, and
• means for determining an image containing perfusion parameters of the first part from a combination of the MR image and the input function determined,
• wherein the control signals cause application of an input pulse sequence for the excitation of spins in a second elongated part of the body and measurement of MR signals for determination of the information for the determination of the input function from the measured MR signals, the second elongated part of the body comprising the part of the vessel, 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.
