Ultrasound is a form of non-invasive imaging. This technology uses sound waves to create an image of internal organs and their architecture. This imaging modality is advantageous because it is a non-invasive way to evaluate a patient for abdominal masses, fluid in a body cavity, or urinary stones in the bladder. These abnormalities can sometimes be difficult to evaluate radiographs (x-rays), which makes ultrasound a unique and valuable tool in a veterinary practice. In certain circumstances, ultrasound can be lifesaving by allowing the clinician to rapidly identify an abnormality and generate a treatment plan. Ultrasound improves the quality of veterinary care in our practice.
