When importing CT data, what anatomy check is essential?

• A. Confirm that the correct site and anatomy correspond to the treatment plan and disease site.
• B. Verify that the imaging modality matches the patient's insurance coverage.
• C. Ensure the patient has cleared the loan balance prior to imaging.
• D. Validate the vendor's certification for CT equipment.

Answer: (A)

Verifying that the CT anatomy matches the site being treated is essential. The CT images feed the treatment plan for target delineation and dose calculation, so the anatomy, positioning, and disease site shown on the CT must correspond exactly to what will be treated. If there’s any mismatch—different region, side, or patient positioning—the plan could be applied to the wrong area or miss the tumor, compromising accuracy and safety. Administrative items like insurance, balances, or vendor certifications don’t affect the anatomical fit between the CT data and the treatment plan, so they aren’t part of the essential CT import check.
