Feasibility of MR temperature imaging for joint cartilage using conventional water proton resonance frequency technique was demonstrated. Laser heating experiments with cartilage samples in vitro excised from porcine knee joints showed clear temperature elevation images of the thin cartilage region of 1-2 mm thickness. The temperature coefficient of the water proton resonance frequency was -0.0108 ppm/degree C. These results may be a first step to apply the noninvasive temperature imaging technique for thermally induced pain-relief for a patient with osteoarthritis.
