Generally, women are required to remove their tops during a breast ultrasound. When a woman undergoes a breast ultrasound, the patient is required to remove as much of her blouse as possible and the breast area is completely exposed to help facilitate the examination. In addition, breast ultrasound not only examines the patient’s breasts bilaterally, but also scans the lymph nodes in the drainage area of the armpits, which can be difficult to do if the patient does not remove her shirt. In addition, removing the shirt during the examination can avoid the coupling agent from getting on the clothes and causing discomfort. Breast ultrasound generally take the supine position, arms up or outward, can fully expose the breast and armpit area, but also can make the breast gland spread flat, flat on the chest wall, easy ultrasound examination and so on. Once a woman has breast discomfort, she should consult a doctor in time for early detection and treatment of the disease.
