T2 and T2* mapping provide information regarding edema and iron deposition in the myocardium. Although many studies reported mapping values of patients with cardiomyopathies and heart transplantation, the actual clinical utility of T2 and T2* mapping values in clinical practice is generally not acknowledged yet. By performing this meta-analysis we provided an overview of all current literature reporting T2 and T2* mapping in heart diseases. Furthermore we evaluated their significance to contribute to insights regarding the clinical applicability.
To close the gap outlined above, learners will:
After reading the article, readers will have a better understanding of T2 and T2* mapping in clinical practice as:
1. In each imaging center reference values of T2 and T2* mapping values should be obtained with similar imaging methods as in patients,
2. Comparison of mapping values with external centers should be avoided,
3. Readers should take knowledge of the clinical recommendations published by Messroghli et al. to standardize image acquisition.
