What should be updated before follow-up scans in bone densitometry?

• A. Calibration settings
• B. Baseline biography
• C. Patient weight
• D. Equipment software

Answer: (B)

For follow-up scans in bone densitometry, it is essential to update the baseline biography of the patient. This is important because the baseline biography includes key demographic and clinical information that can affect bone density measurements, such as age, sex, medical history, and any treatments that may influence bone health. Keeping this information current allows for more accurate comparative analysis between the initial and subsequent scans.

When assessing bone density, understanding how a patient's conditions or treatments may have changed over time is crucial in interpreting the results correctly. For instance, if a patient has started a new medication that affects bone loss or has experienced significant lifestyle changes, these updates are vital to accurately gauge their bone health over time.

Updating baseline biography creates a comprehensive view of the patient's progression and assists healthcare providers in making informed treatment decisions based on the most recent and relevant patient information.
