T2-weighted MRI scans can depict areas at risk of suffering irreversible due to myocardial infarction but are prone to segmentation difficulties due to insufficient suppression of slow blood-flow which is often present in trabeculated left ventricles. B-SSFP sequences are known for their excellent blood-to-tissue contrast and may be employed for accurate segmentation purposes. Combining B-SSFP with T2-weighted scans may improve diagnostic accuracy and facilitate quantitative measurements of the size of non-viable myocardium and areas-at-risk.
