Abstract
Methods Even with accelerated imaging methods the acquisition window for single-shot SSFP techniques can be long (>200-250 ms). A segmented SSFP method is proposed, allowing for shorter acquisition windows and a corresponding capability to acquire multiple slice locations per heart beat as illustrated in Fig 1. If the number of segments is limited, the entire acquisition can be repeated with different preparation durations (TE's) in a single breathhold, enabling T2-mapping. Such a segmented approach presents a number of challenges:

Recent studies demonstrate that hyperintense regions in T2-weighted images in acute myocardial infarction (AMI) reflect the presence of edema [1] and area at risk
Singleshot T2-prepared SSFP methods have been presented for T2-weighted imaging in AMI [2]
