MLO Full Form in Medical term is mediolateral oblique. The MLO view, along with the CC view (cranial-caudal), is among the two conventional mammographic perspectives. This is the most crucial angle because it permits the most breast tissue to be seen.
Pectoral muscle depiction on the MLO view is crucial for judging the accuracy of patient positioning and, by extension, the quality of the image.
To reduce the frequency of false negatives & boost the responsiveness of the mammography, it is crucial that the volume of breast tissues in the image is proportional to the amount of apparent pectoral muscle. Since the majority of breast pathology manifests in the upper outside quadrant, it is crucial that this region be easily discernible on MLO views.
The patient is placed at an angle of 45 degrees at the front of mammography arm of the affected hand, which is resting on the tabletop. The breasts and underarms will be compressed uniformly so that skin is smooth and there are no creases.
It’s important to remember that not all ladies look well with their elbows bent at a normal 45 degrees. It has been shown that adjusting the angle to somewhere between 40 and 60 degrees improves image quality while looking at specific diseases.
