Ultrasound uses sound waves, rather than radiation, to make images of an animal’s organs. Ultrasound can be used to non-invasively evaluate the internal structures of the abdomen, thorax (including the heart), eye, and musculoskeletal structures. Ultrasound images can also be obtained in real time, allowing us to see not only structure, but also motion/function of some of the organs such as the heart. Ultrasound is also used to guide biopsy procedures. Our machine is a Biosound ESAOTE MyLab 50 unit with B-mode, M-mode, color flow Doppler, pulse wave Doppler, and continuous wave Doppler capabilities.
