1. A method for producing an image of a blood vessel of a patient comprising:
- introducing a fluid into a cardiovascular system of the patient;
obtaining magnetic resonance information from the blood vessel;
determining a magnetic resonance parameter in the blood vessel using the magnetic resonance information;
determining a temperature differential in the blood vessel using the magnetic resonance parameter; and
producing an image of the blood vessel in which a brightness or a color of pixels therein is determined by the temperature differential.

Abstract
A method for producing an image of a blood vessel in a patient utilizing temperature sensitive MRI measurement. The method includes introducing a fluid in a blood vessel, obtaining magnetic resonance information from the blood vessel, and determining a magnetic resonance parameter using the magnetic resonance information. The method further includes using the magnetic resonance parameter to determine a temperature differential in the blood vessel and producing an image of the blood vessel based on the temperature differential. Systems for producing an image of a blood vessel in a patient using temperature sensitive MRI measurements are also provided.
