Myocardial T1 mapping at five short axial slices (apex to base from left to right respectively) of the left ventricle of one patient. a Automatically reconstructed map (after automatic removal of myocardial boundary pixels) overlaid on a T1 weighted image with shortest inversion time; (a) Manually reconstructed T1 map. The contours in (b) represent the myocardium region of interest manually selected by the reader. In Fig. c scatter plots are shown of the automatic versus manual myocardium T1 values averaged over the patient volume (left) and each imaging slice (right). Solid lines represent the unity slope line
