Figure 3 Segmental refill curves (solid circles) and corresponding left ventricular signal intensities (solid triangles) reconstructed from a myocardial contrast echocardiography (MCE) perfusion sequence at rest. Upper and lower dashed lines = ALV and A; dotted lines = ± 1 SD of ALV; solid lines = the fitting to y(t) = a·(1 – e–ß·t) + c with the myocardial plateau intensity A = a + c. Segmental data of ß, relative blood volume (rBV), and myocardial blood flow (MBF) are given in s–1, ml·ml–1, and ml·min–1·g–1, respectively. For the calculation of MBFMCE, ß data were transformed into min–1. PET = positron emission tomography.
