Abstract
En 中文
Accurate detection of myocardial iron deposition is essential for diagnosis, risk stratification and therapeutic decision-making. The black-blood cardiac T2* mapping is the guideline-recommended technique for detecting myocardial iron deposition. However, mixtures of fat (MF) can confound the results, because MF also reduces T2* values. The present study proposes a method that reduces MF-related overestimation of iron deposition in cardiac T2* mapping.
