Usefulness of MRI compared with CT for diagnosis of mesenteric lymphoma in a dog

We evaluated the usefulness of MRI and compared it with CT for diagnosis of mesenceric lymphoma in a dog. The results in the plain CT. dynamic CT and plain MR (TIWI and t2W1) images suggested that the mass was a large single nodular lesion with abundant blood perfusion. On enhanced MRI(T1WI) , the mass was depicted as a tumor with adhesion to the gut wall, Exploratory laparotomy confirmed the mass was consistent with the findings on enhanced MRI. We think that MRI might be a useful imaging tool for diagnosis of canine mesenteric lymphoma
