M Mode ultrasound is a valuable tool in veterinary imaging for small animals. It allows for the visualization of various heart structures and valves, providing crucial information about their movements and functions.

The cursor position in M Mode ultrasound helps in tracing the movement of these structures over time. By placing the cursor at specific points, veterinarians can measure the distance traveled by the heart structures and assess their function.

Additionally, M Mode ultrasound can be used in conjunction with an electrocardiogram (ECG) to obtain accurate measurements. This combination allows for a comprehensive evaluation of the heart's performance and aids in diagnosing any abnormalities.

Overall, M Mode ultrasound with its ability to trace movements and provide precise measurements is an essential tool in veterinary imaging, enabling veterinarians to assess the health and function of the heart in small animals.
