In the context of mammography, what does the abbreviation 'MLO' stand for?

In mammography, 'MLO' stands for mediolateral oblique. This position is commonly used during mammographic imaging to obtain a clear view of breast tissue. The mediolateral oblique view helps visualize the breast in a way that includes the glandular tissue while minimizing superimposition of other structures, allowing for better assessment and detection of abnormalities.

In this view, the x-ray beam is angled from the medial (inner) part of the breast to the lateral (outer) part, creating an oblique projection that provides critical information about the breast's internal structures. This technique is essential in ensuring that all relevant tissue is examined and is a standard part of screening and diagnostic mammography protocols.

The other options, while they may sound similar, do not accurately reflect the term used in mammography practice. Understanding the correct terminology is essential for effective communication and practice within the field.
