How should the patient be positioned for breast imaging?

• A. Supine only
• B. Supine or right posterior oblique or left posterior oblique with the ipsilateral arm raised, hand relaxed by the head
• C. Prone position
• D. Sitting upright

Answer: (B)

Positioning aims to create a wide, flat acoustic window so the ultrasound can visualize all breast tissue clearly. Lying on the back (supine) with the arm on the side being scanned raised and resting near the head, or slightly rotating into a posterior oblique position with the same arm elevated, best accomplishes this. Elevating the ipsilateral arm moves the breast tissue away from the chest wall and into the transducer’s path, reduces tissue overlap and shadows, and provides easier access to the entire breast, including the axillary tail and upper outer regions. This setup also helps maintain a stable surface for optimal contact and consistent imaging.

Prone positioning would pull the breast away from the chest wall and distort the anatomy, making it harder to get a good acoustic window. Sitting upright offers less stability and typically poorer access for detailed breast imaging, so it’s not the standard approach.
