Magnetization transfer contrast (MTC) using fast spin echo (FSE) was evaluated with phantom and human breast. Phantom consists of oil, 0.9% NaCl and gelatin with various gelatin-water ratio. On multi slice FSE images, the attenuation of signal intensity in gelatin and mammary gland due to MTC was observed. Magnetization transfer ratio (MTR) was calculated from the center slice acquired with multi slice FSE and the image acquired with single slice FSE. Phantom examination proved the accuracy of MTC using FSE to be valid. MTR of fat tissue was less than that of mammary gland. MTR of carcinoma was more than that of mammary gland. This study suggests that MTR might be a new indicator for assessment of tumor tissue characterization.
