What should you check before performing an L spine DXA scan?

• A. The patient's history of osteoporosis
• B. The operator's manual of the machine
• C. The calibration of the scanner
• D. The patient's height and weight

Answer: (B)

Before performing an L spine DXA scan, one essential step is to check the calibration of the scanner. Proper calibration ensures that the machine provides accurate measurements of bone density, which is crucial for diagnosing conditions like osteoporosis. If the scanner is not calibrated correctly, it might yield erroneous results, potentially leading to incorrect diagnoses and treatment plans for patients. Regular calibration checks are a standard practice in maintaining imaging equipment to ensure optimal performance and reliability. Additionally, while other factors such as patient history and physical measurements are important considerations in the overall assessment of osteoporosis risk, they do not directly impact the immediate technical readiness of the DXA machine itself. Checking the operator's manual is also necessary for understanding the machine's functions and guidelines, but the primary focus before a scan must be on ensuring that the equipment is calibrated correctly for accurate imaging results.
