The Gold Standard in Veterinary Imaging Diagnostic Evaluation
Nasal cancer causes progressive nasal obstruction and often unilateral discharge, bleeding, and facial asymmetry. Imaging evaluates tumor extent, turbinate destruction, and involvement of adjacent sinuses and skull base. CT is usually preferred because it shows complex bony anatomy and soft tissue with high detail. MRI can better assess soft tissue spread and intracranial involvement. Radiographs can screen but miss subtle invasion. Ultrasound is limited. Nuclear studies are selected for metastasis evaluation.
