Myocardial cine T1 mapping using dynamic multiple trigger delay acquisition

Motivation: Myocardial T1-mapping is a widely used quantitative method to evaluate the characteristics of myocardium. Commonly, the cardiac trigger delay (TD) during the diastolic phase depends on the settings of the system. However, because myocardial characteristics can affect both diastole and systole, acquiring T1 mapping at various cardiac phases may have clinical significance. Goal(s): To acquire cardiac T1 mapping at various cardiac phases in one scan. Approach: Dynamic trigger delayResults: The proposed technique was successfully implemented. Application of image registration technique has improved the accuracy of T1 value quanitification. Impact: CINE T1 mapping can acquire quantitative mapping of several different cardiac phases simultaneously in one scan; it may be useful for more detailed diagnosis of myocardial properties.
