Research progress of T1 and T2 mapping techniques in acute myocardial infarction
Acute myocardial infarction(AMI)is a serious disease threatening to human health,with morbidity and mortality continue to increase.With the popularization of reperfusion therapy and revascularization technology,the prognosis of AMI has been improved,but the mortality rate of patients is still high.Therefore,the early and accurate diagnosis of AMI is of great clinical significance.In recent years,the use of cardiac magnetic resonance(CMR)quantitative techniques,including T1 and T2 mapping techniques,has been advocated,which can accurately and quantitatively assess myocardial tissue characteristics and provide very valuable information for diagnosis of AMI.Compared with traditional CMR,these techniques can directly measure T1 and T2 values,and quantitatively evaluate the extent and degree of myocardial infarction.Accurate assessment of myocardial infarction is of great value for the treatment of AMI and the evaluation of prognosis.This article reviews the principle of T1 and T2 mapping techniques and its research progress in AMI,aiming to improve the accuracy of early clinical diagnosis and provide new ideas and basis for treatment decision-making and prognosis assessment.
