To diagnose and treat heart muscle diseases such as myocardial infarction and hypertrophic cardiomyopathy accurately using cardiac MRI, it is important to diagnose the degree of fibrosis and the characteristics of the myocardial tissue. T1 mapping images of cardiac MRI can be used to measure the T1 relaxation time and the extracellular volume fraction, which are indicators of myocardial damage. However, different MRI machines and imaging methods in different hospitals can lead to different measurement values, making it difficult to compare data and establish normal range data for each hospital. Professor Choi Byung-Wook has developed a method to standardize MRI measurement values across hospitals, allowing for the application of common data for disease diagnosis and enabling the use of big data-based accurate diagnosis using cardiac MRI. This research was supported by the Korea Research Foundation's Biomedical Technology Development Project, the Ministry of SMEs and Startups' BIG3 Startup Commercialization Support Project, and sponsored by Dong-A University Life Science. The research was conducted in collaboration with Professor Park Eun-Ah's team from Seoul National University Hospital's Department of Radiology, Professor Jung Jung-Im's team from Seoul St. Mary's Hospital's Department of Radiology, and Phantomics Co., Ltd. The research results were published in the recent issue of European Radiology (IF 7.034).
