Gastroparesis: Concepts, Controversies, and Challenges

Figure 1

Sample emptying curves showing the results of scintigraphic studies of gastric emptying for four different patients as compared to the reference of control persons indicated by the dotted line. While the findings for patients 1 and 2 are unequivocal with normal (1) and slow (2) emptying, the other two patients have less consistent results with delay at early (3) or late (4) times points only.
