Positioning
Mediolateral oblique
view MLO
For routine examinations, the MLO projec-
tion is to be preferred over the 90° lateral
projection. More of the breast tissue can
be seen in the upper outer quadrant and
the axilla. Furthermore, it is easier to carry
out the application with this setting.
Criteria:
The pectoral muscle should be depicted obliquely from above and
be visible down to the level of the nipple or further down. The
shape of the muscle should be depicted weakly convex as a sign
that the muscle is completely relaxed and medially prominent.
The compression should be proper over the whole image area.
The nipple should be depicted in profile and a small stomach fold
should be visible as a sign that the whole breast is reproduced.
