What is the cassette size used for a lateral hand x-ray?

The standard cassette size for a lateral hand x-ray is 8" x 10". This size is optimal because it provides sufficient coverage of the hand while also being manageable for patients and technologists during the imaging process. The 8" x 10" size allows for the anatomy of interest—the hand and wrist—to fit comfortably within the radiographic field without unnecessary exposure or excess background noise.

Using the appropriate cassette size is crucial for producing high-quality images that facilitate accurate interpretations. Larger cassettes, like 10" x 12", 12" x 14", or 14" x 14", may capture more area but could lead to underexposure of the hand itself, making it harder to discern details important for diagnosing fractures or other conditions in the skeletal system of the hand. Thus, the 8" x 10" cassette size is the standard practice for lateral hand x-rays.
