Derivation of the internal flow fraction. (a) For the calculation of internal flow fraction, the three-dimensional LV volume is superimposed on the four-chamber long-axis and short axis SSFP images and the left ventricle is divided into 16 wedge-shaped regional volumes. (b) the Internal Flow Fraction discriminates between patients and healthy controls with 95% accuracy. Reproduced with permission from Fornwalt BK, et al. [46]
