What is the standard cassette size for an AP lumbo-pelvic x-ray?

• A. 10"x12"
• B. 14"x14"
• C. 14"x17"
• D. 16"x20"

Answer: (C)

The standard cassette size for an AP lumbo-pelvic x-ray is 14"x17". This size is commonly used because it captures a wide enough field to include both the lumbar spine and pelvis in a single image, ensuring that the important anatomical structures are fully visualized for diagnosis. The dimensions provide an appropriate balance between detail and coverage, allowing for effective imaging of areas that might be affected by conditions such as fractures or degenerative changes. In practical applications, this size is preferred in clinical settings as it fits the standard radiographic protocols for these types of examinations, facilitating accurate assessments and comparisons in follow-up studies.
