Figure 5. Images taken at the same level of the oesophagus in one volunteer, using the optimized high resolutionT₂ weighted sequence (a) without and (b) with cardiac gating. The sequence with cardiac gating provides improved image quality. This is illustrated by the clarity of the oesophageal wall submucosa (black arrow), the aortic wall (white arrow) and right pleural reflection (fine black arrow).
