When preparing for a VD radiograph of the abdomen, should measurements be taken in centimeters or inches?

When preparing for a VD (ventrodorsal) radiograph of the abdomen, measurements are typically taken in centimeters. Using centimeters provides a more precise and standardized measurement that aligns with radiographic protocols. In veterinary medicine, particularly in radiology, centimeters are preferred because they allow for easier calculations and understanding when determining exposure factors, positioning, and overall anatomy.

Centimeters are commonly used in science and medicine for measurements that require a degree of accuracy, especially when dealing with small structures, such as organs in the abdomen. This measurement unit helps ensure consistency in imaging and assists in comparing results across different cases and studies.

In contrast, inches and feet are larger units that can lead to less precise imaging, as they may not capture the fine details required for proper diagnosis or assessment. Millimeters, while precise, are not the standard measurement for abdominal radiographs in veterinary practice, making centimeters the more appropriate choice.
