Abstract
This paper describes the spectrum of imaging features of oesophageal adenocarcinoma seen using highresolution T2weighted T2W magnetic resonance imaging MRI Thirtynine patients with biopsyproven oesophageal adenocarcinoma were scanned using an external surface coil A sagittal T2W sequence was used to localise the tumour and to plan axial images perpendicular to the tumour Fast spinecho FSE T2W axial sequence parameters were TR/TE 3300–5000 ms/120–80 ms field of view FOV 225 mm matrix 176×512reconstructed mm to 256×224 mm giving an inplane resolution of between 128×044 mm and 088×100 mm with 3mm slice thickness Thirtythree patients underwent resection and the MR images were compared with the histological wholemount sections There were four T1 12 T2 and 17 T3 tumours The T2W highresolution MRI sequences produced detailed images of the oesophageal wall and surrounding structures Analysis of the imaging appearances for different tumour T stages enabled the development of imaging criteria for local staging of oesophageal cancer using highresolution MRI Our study illustrates the spectrum of appearances of oesophageal cancer on T2W highresolution MRI and using the criteria established in this study demonstrates the potential of this technique as an alternative noninvasive method for local staging for oesophageal cancer
