| Outline of Final Research Achievements |
We examined the utility of Phase-contrast MRI (PC-MRI) for evaluation of therapeutic efficacy to pulmonary hypertension. First, we tried to prove the reproducibility of the measured value derived from PC-MRI between the different MR apparatus. The indexes obtained from time flow curve derived from PC-MRI was thought to possess high reliability. Thus, measured values can be used as general values in pulmonary blood flow evaluation. Next, we reported two cases with chronic thromboembolic pulmonary hypertension undergoing balloon pulmonary angioplasty (BPA) where PC-MRI was useful in assessing its therapeutic efficacy. In these two cases, the pulmonary flow volume was increased after BPA.
