What is one way compression aids in distinguishing superimposed areas of glandular tissue?

Compression in mammography plays a critical role in enhancing image quality and interpretation. One of the primary benefits of compression is that it helps to spread apart overlapping tissue, particularly glandular tissue, which can often mask or obscure lesions. Glandular tissue is denser than fatty tissue, and when layers of glandular tissue overlap, it can create challenges for accurate diagnosis. By applying compression, the technician can reduce the thickness of the breast tissue being imaged, allowing for clearer separation of these overlapping layers. This improved delineation makes it easier for radiologists to detect any abnormalities such as tumors, thus improving diagnostic accuracy.

Additionally, compression reduces motion blur and equalizes the tissue thickness, allowing for a more uniform exposure and better visualization of fine details within the breast. This method is essential for producing high-quality mammograms, where clear visibility of potential pathologies is crucial for diagnosis.
