Example of persistent hyperintense signal on STIR at 6-month follow-up. Matched diastolic images obtained in a 76-year-old male with reperfused inferior MI. The acute images demonstrate a large area at risk on STIR (A) with a smaller infarcted zone (B). The images at 6 months show the infarct zone has has become slightly larger (D), whereas the STIR images (C) show near homogenous signal distribution but a small remaining area of hyperintensity.
