We
developed a novel fast high-resolution free-breathing 3D isotropic T2
mapping technique for the heart. The resulting whole-heart T2 maps
were both accurate and sharp, and the T2 values in the myocardium matched
those measured with routine 2D T2 mapping (p=0.57).
Sharp source images and precise T2 maps in healthy volunteers. A-E) The source images contain sharp
features (papillary muscles, edge definition) and are well aligned to one
another. F-H) The resulting short-axis T2 map and its two perpendicular views are
similarly sharp.
T2 mapping in a patient with myocardial infarction.
A) LGE can be observed in the septum. B) The corresponding T2
map obtained with 2D T2-prepared bSSFP shows a small T2 elevation
in the infarcted area. C) The proposed technique accurately confirms the T2
elevation.
