T2 Measurement can be used to detect pathological changes in tissue for a variety of clinical applications, including identification of edema and iron overload. Rapid T2 mapping in the heart is challenging because of the need to acquire adequate spatial resolution within clinically acceptable breath-hold duration of 20s or less. We propose to extend a recently developed breath-hold T2 mapping pulse sequence to achieve higher spatial resolution, by implementing a joint reconstruction algorithm that combines compressed sensing and parallel imaging. This accelerated T2 mapping pulse sequence with high spatial resolution was validated in vitro and in vivo.
