Veterinary oncology: radiology and ultrasonography exams in decision makingOncologia veterinária – exames radiográficos e ultrassonografia na tomada de decisões

Imaging exams are frequently requested during assessment of oncological patients. Although advanced imaging techniques are already available in veterinary medicine, radiographic and ultrasonographic exams remain the basic diagnostic tools in veterinary oncology. This review describes some considerations to improve clinical approach to animals with neoplastic lesions based on the use of radiographic and ultrasonographic exams. The role of these modalities in screening, diagnosis, staging, treatment choice, and follow-up of cancers is discussed. Additionally, a workflow for some type of tumors is described, such as mediastinal lymphoma in cats, as well as mast cell tumors and osteosarcoma in dogs. Situations that require other techniques are also discussed.
