Idiopathic scoliosis occurs most often in adolescents, and because the angle of scoliosis tends to change considerably during adolescent development, children often require periodic review with multiple x-rays. Studies have shown that repeated low-dose X-rays may increase the risk of cancer, especially in women with diseases such as breast cancer. In the human body, the breast and thyroid glands are the most sensitive to the effects of radiation exposure. Excessive exposure to X-rays during childhood or adolescence may increase the risk of cancers such as breast or thyroid cancer. Therefore, especially for children, radiation exposure should be minimized as much as possible. The Oxford low-dose radiation projection technique is designed to minimize radiation exposure to the breast and thyroid glands in the anterior aspect of the child’s body. The key to this technique is posterior-anterior projection imaging. Compared to anterior-posterior photography, when posterior-anterior photography is performed, the radiation first passes through the skin and soft tissues of the back, and by the time it reaches the anterior breast and thyroid, most of the radiation has been absorbed. In other words, during the specific radiographic examination, the body must be facing the radiographic bulb (i.e., A in the figure); in addition, attention should be paid to increasing the distance between the radiographic bulb (A) and the receiving plate (B) (radiographic receiving distance), which generally requires 12 feet (i.e., 3.6 meters), and leaving at least 15 cm of space between the chest and the receiving plate, i.e., do not use both hands to hold the receiving plate, but should keep a certain gap with it. In this way, the amount of radiation received by the sensitive parts of the body, including the thyroid and breast, will be 50 times or less than the amount received during a conventional anterior-posterior radiograph through the above measures. Since conventional chest fluoroscopy and other examinations are taken in the anterior-posterior position, i.e., the body is facing the radiation projection tube. Therefore, please remember that when taking your child for a scoliosis review, make sure that your child turns around and faces the bulb so as to minimize the radiation exposure to the front glands of the body.
