All follow-up DXA scans should be compared to which scan?

• A. Baseline scan
• B. Final scan
• C. Primary scan
• D. Control scan

Answer: (A)

The appropriate scan to compare follow-up DXA scans to is the baseline scan. The baseline scan is the initial bone densitometry assessment performed on a patient, establishing a reference point for future evaluations. This initial scan provides critical information about the patient's bone density status at a specific time, allowing for effective monitoring of changes over time.

Comparing follow-up scans to the baseline scan enables healthcare providers to determine if there has been any significant loss or gain in bone density, which is vital for assessing the effectiveness of treatments or lifestyle changes and for making informed clinical decisions regarding the patient's bone health management. By using the baseline scan as a reference, clinicians can accurately track the progression of conditions such as osteoporosis and adjust treatment protocols as necessary.
