For a VD radiograph of the abdomen, where should you measure?

In a VD (ventrodorsal) radiograph of the abdomen, the correct area to measure is the widest point of the belly. This is important because the measurement should reflect the area that will provide the most accurate representation of the abdomen's overall size and shape. When positioning an animal for this type of radiograph, ensuring that the widest part of the abdomen is measured helps to determine the appropriate settings for the x-ray exposure, which is crucial for producing a clear and useful image.

Measuring at the widest point allows for proper film or digital sensor placement and ensures that all relevant anatomical structures are captured in the radiograph. This careful measurement aids in diagnosing conditions within the abdominal cavity, making it possible for veterinarians to assess organs such as the stomach, intestines, liver, and spleen effectively.
