Contiguous, but not patchy, myocardial infarction has
been measured using 3D and 2D DE-MRI and validated using
histochemical and histopathological staining. The
purpose of this study was to: 1) measure patchy and
contiguous infarction size using delayed enhanced 3D
inversion recovery (IR) gradient echo (GRE) in beating
and non-beating swine hearts and 2) compare the 3D
measurements against 2D-IR GRE, histochemical and
histopathological staining. Myocardial infarction
measured on 3D MRI correlated well and in a good
agreement with microscopic data. This imaging sequence
has the potential to measure diffuse and large acute
myocardial infarction and has minimal motion artifacts.
