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.
