Two- and Three-Dimensional Examination of the Stomach (Virtual Gastroscopy): Technical Note Peggy P.W. Yen, BSc, Giles Stevenson, FRCP(C) Canadian Association of Radiologists Journal Volume 61, Issue 1, Pages 41-43 (February 2010) DOI: 10.1016/j.carj.2009.10.008 Copyright © 2010 Terms and Conditions

Figure 1 Computed tomographic study conducted after a routine biopsy of an endoscopically benign ulcer revealed malignancy. The 3-dimensional image shows an elevated lesion, with depressed center and long bridging folds (black arrow), suggesting small but advanced carcinoma. The 2-dimensional image confirms loss of the adjacent fat line with transmural spread. Other slices showed enlarged lymph nodes, which were confirmed to be metastatic disseminations at wedge resection of the tumour.

Figure 2 Discovery of a submucosal lesion on endoscopy initially led to consideration of endoscopic resection with saline solution elevation. However, subsequent Computed tomography showed no exophytic component of the tumour (white arrow) and instead had extension into the serosa, rendering endoscopic resection inappropriate. Wedge resection of the gastrointestinal stromal tumour was eventually performed.
