Phase sensitive inversion recovery (PSIR) reconstruction is a commonly used technique for myocardial infarction detection. Myocardial fat, however, is a potential source of false positive detections. Direct inclusion of fat saturation in regular PSIR is not straightforward. In this work, a phase-sensitive reconstruction technique is combined with Dixon imaging to achieve phase-sensitive Dixon IR imaging. This technique can provide phase sensitive water and fat images without compromising scan efficiency. In vivo tests demonstrated its feasibility and advantages over regular PSIR in body imaging.
