What does the term “compression” refer to in mammography?

In mammography, the term "compression" specifically refers to the process of flattening the breast during imaging. This technique is crucial for several reasons. First, compression helps to spread out breast tissue, which improves the visibility of any abnormalities by reducing the effects of tissue superimposition. This allows radiologists to obtain clearer images that are essential for accurate diagnosis. Additionally, compression reduces the amount of radiation needed to produce the images, thereby minimizing the patient's exposure to X-rays. It also helps to stabilize the breast during imaging, which can enhance the quality of the mammogram and provide better diagnostic information. Overall, breast compression is a key component of mammographic imaging, ensuring better image quality while maintaining safety for the patient.
