Figure 6. Images taken at the same level of the oesophagus in one volunteer. Increasing the repetition time(TR) from (a) 3 beats (effective TR 2250 ms) to (b) 6 beats (effective TR 4000 ms) caused blurring within the image. The oesophageal wall submucosa (black arrowhead), muscularis propria (black arrow), and right pleural reflection (white arrow) are more clearly seen with an effective TR of 2250 ms (3 beats).
