Phase-Sensitive Inversion Recovery (PSIR) has been widely used in cardiac imaging to detect infarcts by providing consistent high contrast between infarcts and normal myocardium. Recently, it has been shown as an improved intraplaque hemorrhage detection tool with good blood suppression and as a possible MRA tool in carotid atherosclerosis imaging. However, considerable amount of reconstruction artifacts can be found in PSIR sequence acquired short Inversion Time (TI). In this abstract, we sought to analyze the cause of these artifacts and propose a solution.
