The sonographer or examiner should:

• Review data acquired during the lower extremity arterial duplex ultrasound exam to ensure that a complete and comprehensive evaluation has been performed and documented.
• Explain and document any exceptions to the protocol (i.e., study omissions or revisions).
• Determine any change in follow-up studies, review previous exam documentation so that the current evaluation can document any change in status; and, to duplicate prior imaging and Doppler parameters.
• Record technical findings required to complete the final diagnosis on a worksheet or other appropriate method (e.g., computer software), so that the findings can be classified according to the laboratory diagnostic criteria.
• Document the exam date, clinical indications, sonographer performing the evaluation, and exam summary in the patient’s medical record.
