The Gold Standard in Veterinary Imaging Diagnostic Evaluation
Bowel cancer refers to malignant intestinal tumors causing chronic GI signs and possible obstruction. Imaging evaluates segmental wall thickening, motility, and regional lymph nodes, plus metastatic disease. Ultrasound is usually first because it identifies thickened bowel layers and lymphadenopathy and can guide biopsy. CT improves staging by detecting peritoneal, mesenteric, and distant lesions. Radiographs are less sensitive, often showing gas pattern changes. MRI is for select characterization; nuclear imaging supports metastatic assessment in specific cases.
