Abstract

JARAMILLO-CHAUSTRE, Xavier Leonardo; BUSTAMANTE-CANO, John Jairo  and  GOMEZ-PARRA, Fernando. Lymphography by MRI for animal model canine. Iteckne [online]. 2017, vol.14, n.1, pp.46-61. ISSN 1692-1798.

For this study were included two groups, one of 12 healthy animals and another of 10 animals affected by disease conditions in the mammary gland. With the anesthetized animal were used magnetic resonance imaging to visualize the lymph ducts and lymph nodes in the inguinale area in potentiated series in 3D TOF in dorsal plane. In both groups it was administered gadopentetate dimeglumine. To validate the technique used, were considered in the images three structures (air, fat and muscle) which IS showed significant difference between glandular breast tissue (IS 184.8 ± 28.2) and regional lymph nodes (IS 51.3 ± 5, 4), allowing to determine the benchmark for the study. It is concluded that the use of a low field equipment of MRI provides enough information to differentiate signal intensities of lymph nodes that collect lymph from pathological processes regarding healthy lymph nodes in dogs.
