- W2384644112 abstract "Objective: To study the application of MRI in the diagnosis of esophageal carcinoma. Methods: Sixty-four patients with esophageal carcinoma confirmed by biopsy and pathology were reviewed and analyzed. Spin-echo MR images were obtained with a field of view(FOV) of 23cm × 23cm ～ 36cm × 36cm, section thickness(ST) of 3. 5 ～ 4mm and matrix size(MTX) of 192 × 256 in sagit- tal view. And FOV of 20cm × 20cm ～ 26cm × 26cm, ST of 6～10mm, Mad of 192 × 256 in transaxial view. All images were obtained with 3～4 signal acquisition. Results: On T1WI MR images the entire esophageal wall showed low to intermediate signal intensi- ty. However, on T2WI the mucosa and submucosa of the esophageal wall showed high signal intensity while the muscularis propria showed low or intermediate signal intensity. The high signal line of the mucosa (and submticosa) of the esophageal wall was seen chear- ly. Compare with normal site in sagittal images, carcinoma appeared as an irregular mass of low or intermediate signal intensity on T1WI, and low to intermediate or inhomogeneous signal intensity on T2WI. In transaxial section, asymmetric increase in thickness of the esophageal wall resulted in lumpy mass of soft - tissue, the esophageal lumen showed irregular stenosis and the high signal line of the mucosa (and submucosa) of the esophageal wall appeared to be disrupted by the tumor mass. Condsston: MR images provide greater contrast of soft - tissue structure than those obtained with CT. Especially on T2WI, it can clearly divide the mucosa(submucosa) and the musoularis propria of the esophageal wall. Due to the advantage that MRI can show panorama of the esophagus in sagittal view, MRI is highly valuable in the diagnosis of esophageal carcinoma." @default.
