Outline of Final Research Achievements

In order to execute high intensity focused ultrasound (HIFU) therapy for breast and bone marrow safely and effectively, we planned to establish a noninvasive and quantitative temperature imaging technique using spin-lattice relaxation time (T1) of proton of methylene chain observed by magnetic resonance imaging (MRI). Based on a new finding that the signal intensity ratio of the chemical shift components of fatty acid in bovine and porcine tissues is insensitive to temperature, we have proposed a novel T1 estimation technique using the ratio among the nine fat signal components as a prior knowledge in the image processing following multiple-point Dixon and multiple flip angle imaging. The usefulness and robustness of the technique was demonstrated with numerical simulation.
