opposite arm of breast being examined is holding bar while the other arm is externally rotated
Lift the posterior lateral aspect of the breast onto the detector.
Drape the central lateral breast over the corners of the detector.
Have the patient's head turned facing the ipsilateral breast.
On the side being imaged, the patient's arm hangs relaxed with humerus externally rotated.
determine skin vs breast tissue calcifications
become familiar with both of her brests
monitor nipple discharge
excise cancerous lumps
less sensitive to low-dose radiation
not related to radiation sensitivity
less sensitive to radiation
more sensitive to radiation
during needle localization to provide a shorter rout to an inferior lesion
all of the above
to maximize the amount of tissue visualized in patients with kyphosis
to improve visualization of lesions in the upper most aspect of the breast by reducing the object-to-image receptor distance (OID)
Compression increases image sharpness by reducing the focal spot size.
The compressed breast requires increase kVp to penetrate the thicker tissue.
Compression decreases subject contrast by reducing the thickness of the penetrated tissue.
Compression increases the uniformity of the breast, making diagnosis easier.
25 - 45 power drive and upper limits on manual 60-65 lbs
None of the above
111 N (25 lbs)
200 N (45 lbs)
178 N (40 lbs)
Compression that should be just sufficient to immobilize the breast
The maximum to which the patient's breast can actually be compressed
The amount of compression the patient can tolerate.
necessary--- digital imaging cannot correct for over exposure
unnecessary--- digital imaging automatically corrects exposure mistakes
unnecessary--- digital imaging corrects unsharpness by altering the spatial display
necessary--- digital imaging cannot correct macros such as motion unsharpness
