Inferomedial superolateral oblique projection

Inferomedial superolateral oblique projection is useful for stereotactic biopsy positioning. This projection allows access to the inferior aspect of the breast to achieve shortest skin to abnormality distance. It is also useful in the nonconforming patient.

Technique

Rotate C arm to about 125°. With the patient facing the unit, bring the lateral portion of the breast against the image receptor. Pull the breast outward and upward and apply compression. The patient may be asked to bend forwards to prevent the abdomen from interfering with the image.
