Question

In scoliosis imaging, breast tissue dose for PA imaging is approximately ____ of the dose for AP imaging.

1) 1
2) 5
3) 10
4) 50

Answer 1

The breast tissue dose for PA imaging in scoliosis is approximately 1/10th of the AP imaging dose, highlighting the importance of patient positioning to reduce radiation exposure.

Step-by-step explanation:

In scoliosis imaging, breast tissue dose for PA (posteroanterior) imaging is approximately 1/10th of the dose for AP (anteroposterior) imaging. This means that the PA position significantly reduces radiation exposure to breast tissue when compared to the AP position. It's important to consider the positioning of patients during x-ray procedures to minimize unnecessary radiation exposure while obtaining the necessary diagnostic information.
