Synopsis

Keywords: Image Reconstruction, Cardiovascular, T2*T2* CMR is widely used for detecting hemorrhagic myocardial infarction (MI). However, the conventional T2* CMR (2D breath-held, ECG-gated, multi-gradient-echo T2*) can suffer from limited spatial resolution and motion artifacts. We have recently developed a time-efficient, fully ungated, free breathing, 3D T2* mapping approach using a low-rank tensor (LRT) framework to address the above issues.
