A. Relative signal intensity in three gut regions (A, B and C in Figure
) following oral pineapple juice administration. ROIs were A: stomach (open circles, solid line), B : proximal small bowel (filled squares, dashed line), and C: more distal small bowel (cross, dotted line). B. Relative signal intensity differences (as a % of maximum) between stomach and distal small bowel (A – C; filled circles, solid line), and between proximal and more distal small bowel (B – C; open squares, dashed line).
