Abstract:
Objective To detect the meshwork of tiny lymphatic channels at bilateral vertebral body and ventral aorta at 3.0 Tesla and to probe the relationship between its detective ratio and some diseases.Methods Fat-suppressed T2-weighted imaging in 91 patients was performed at the upper abdomen. The meshworks of tiny lymphatic channels at bilateral vertebral body and ventral aorta on contiguous axial and coronal images were reviewed. The classifications of the lymphatic meshwork were made according to its width and length on coronal images. The differences in the detective ratios of the lymphatic meshwork between control group and the risk ones including portal hypertension group, choledochus obstruction group and malignant tumour group were analyzed.Results Right- or left-sided lymphatic meshwork at vertebral body or ventral aorta were 34.07%(31/91),32.97%(30/91),32.97%(30/91) and 43.96%(40/91) respectively. The detective ratio of the lymphatic meshwork on the side of the ventral aorta was higher significantly in the portal hypertension group than that in the control or malignant tumour one (P0.05). Conclusion Meshwork of tiny lymphatic channels at bilateral vertebral body and ventral aorta allows to be detected on fat-suppressed T2-weighted imaging at 3.0 Tesla, and the portal hypertension may influence the detective ratio of the lymphatic meshwork on the side of the ventral aorta.
