Outline of Final Research Achievements |
Regarding the development of a new diagnostic technique by myocardial SPECT / CT, Myocardial perfusion test was performed using SMARTZOOM collimator (IQ-SPECT) or low energy collimator. The results of IQ-SPECT system, obtained with short-time acquisition were compared with those of conventional shooting, and the analysis results were shown to be useful for clinical use. In the study "Risk stratification by left ventricular phase analysis", the index of left ventricular dyssynchrony was measured using phase analysis and QGS software which can evaluate left ventricular function. And the factors from phase analysis were validated in patients with coronary artery disease. In the research "Research on risk stratification by N-13 ammonia", N-13 ammonia was synthesized using ammonia synthesizer and the study was performed to develop a new diagnostic technique for ischemic heart disease by TOF technology.
