What is the role of ultrasound in oncological diagnosis?

Ultrasound plays a crucial role in oncological diagnosis primarily by visualizing internal organs. This imaging technique allows veterinarians to assess both the size and location of tumors, providing important information for further diagnostic and treatment planning. Ultrasound is non-invasive and does not involve radiation, making it a preferred method for examining soft tissues, such as organs and mass lesions.

Through ultrasound, practitioners can identify abnormalities, guide biopsies, and monitor the progression of cancer. It provides real-time imaging, which is particularly beneficial in evaluating fluid-filled structures and distinguishing between benign and malignant lesions. The detailed visualization aids in determining the extent of the disease and the involvement of surrounding tissues, facilitating accurate staging of tumors and informing therapeutic strategies.

As for the other options, performing surgical biopsies usually requires a different approach, such as cytological or surgical sampling techniques, while traditional x-rays still have their place in imaging protocols, particularly for certain types of bone and lung abnormalities. Ultrasound cannot administer chemotherapy, as it is solely an imaging tool and not a treatment modality.
