Wheelchair pt projection

fb lm

Projection for nipple not in profile

image entire breast if necessary image separately use nipple markers can prevent unnecessary imaaging

Projection for skin folds or wrikling of the breast

this may be impossible to avoid in the elderly use index finger avoid pushing outside the compression field

Projection for pt with uneven breast

if ml IR must be parallel to the pectoral muscle IR should be positioned in the axilla 2 images for each routine proj posterior and anterior may be necessary flex paddle avoid over compression of posterior breasg tissue to achieve achieve adequate compression of anterior breast

sio

It is the breast tissue sample removed during a biopsy

specimen

A radiograph of the specimen is necessary to ensure the area under suspicion is totally removed and the margins are clean.In imaging the specimen:

Speed and efficiency are important because the patient may be under anesthesia.Always use compression when imaging larger specimensMagnification may help to visualize microcalcifications
