Radiology Practice Test

Compression is applied to the breast during mammography primarily to reduce tissue thickness and improve image quality. By compressing the breast, the radiographer minimizes the amount of overlapping tissue, which can obscure clear imaging. This process allows for better visualization of abnormalities or potential lesions, as it spreads the breast tissue more evenly and allows for a more detailed examination.

Furthermore, reduced tissue thickness helps in enhancing the overall resolution of the images obtained, making it easier for radiologists to interpret results accurately. In addition to improving image quality, compression also helps to reduce the dose of radiation needed, as less tissue requires less radiation to penetrate effectively. This dual benefit of improved visibility of structures and radiation safety underscores the importance of compression in mammography.

While other aspects like patient comfort, movement prevention, and radiation safety are considerations in the overall procedure, the primary function of compression centers on enhancing the clarity and diagnostic capability of the mammography images.
