Final answer:
The MLO position in mammogram exams is used to show the lateral breast tissue, including the axillary tail. This position is helpful in detecting abnormalities in the upper outer quadrant of the breast. It improves the accuracy of breast cancer detection.
Step-by-step explanation:
The MLO position in mammogram exams stand for 'mediolateral oblique' position. It is a specific angle used to take X-ray images of the breast. In this position, the breast is compressed between two plates and the X-ray machine is angled from the side (mediolateral) and slightly diagonal (oblique).
The MLO position is best demonstrated by showing the lateral breast tissue, including the axillary tail which extends into the armpit area. This position is useful for detecting abnormalities in the upper outer quadrant of the breast, which is a common location for breast cancer.
By using the MLO position, radiologists can get a better view of the breast tissue and improve the accuracy of breast cancer detection.
