Risk-based diagnostic approach in cardiac imaging

点击翻译按钮获取中文摘要

While multiple modalities are available in cardiac imaging, information from imaging and clinical backgrounds were integrated in this study to estimate the patients risk for serious cardiac events. Databases of myocardial perfusion single-photon emission computed tomography were standardized, and parameters derived from fatty acid and sympathetic imaging were standardized. The specific software for standardized measurements was also created. Factors related to the high-risk and low-risk patients were determined by multicenter studies, and the risk-calculation software and risk charts were published. Risk-based diagnostic approach provided essential information for utilizing multiple diagnostic modalities.
