The Gold Standard in Veterinary Imaging Diagnostic Evaluation
Thyroid adenoma is a benign neoplasm that may be functional, producing excess thyroid hormones or remain nonfunctional. Dogs more often present with subtle endocrine signs, while cats can show prominent hyperthyroid effects if functional. Imaging typically starts with ultrasound for mass localization, then nuclear scintigraphy for functional assessment, followed by CT/MRI for invasion staging.
