FIGURE 5. Schematic representation of global meridional and circumferential left ventricular curvatures in healthy volunteer and in patient with dilated cardiomyopathy and of segmental curvatures within patient segments showing SPECT defects. Compared with left ventricular walls from healthy volunteer, those from patient are less curved in circumferential direction (red arrows on short-axis slices) but more curved in meridional direction (red arrows on long-axis slices). In addition, in patient segments showing SPECT defects, walls are more curved (green arrows) and thinner than in other segments from this patient.
