craniocaudal view

(redirected from CC view)

craniocaudal view

A standard view taken from above during routine-screening mammography and during diagnostic mammography. In the CC view, the entire breast parenchyma should be depicted; the fatty tissue closest to the chest wall should appear as a dark strip on the mammogram and behind that, one should see the pectoral muscle. The nipple should be depicted in profile.

In a CC view, the x-ray enters cranially and the film is located caudally.
The x-ray beam in the CC view is parallel to the vertical axis of the body.
On a CC view, the label RCC or LCC will be in a lateral position.
The localization to the medial or lateral breast is straightforward on the CC view because the x-ray beam is parallel to the vertical axis of the body.
Because the x-ray beam is parallel to the horizontal axis of the body and oriented 90[degrees] with respect to the CC view, a mass above the PNL is truly in the upper half of the breast.
One useful mnemonic in localizing breast masses is "lead falls and muffins rise." A mass located laterally on the CC view will actually be lower in the patient than predicted by the MLO view.
In this technique, the MLO view is placed in the center and the CC view is placed on either side with the nipple at the same level and pointing in the same direction (Figures 13 and 14).
For example, suppose a density is only seen on the MLO view but not the CC view. An MLO spot compression confirms that the lesion is real.
A caudal-cranial view ("from below") visualizes upper breast lesions better than the standard CC view does.
When lobular carcinoma is visible on a mammogram it is often better seen on the CC view.
In examining the images from a screening mammogram, the radiologist places the MLO views and CC views of each breast next to each other so they can be compared.
For this study, radiation exposure with tomosynthesis was twice that of a standard mammogram dose or equal to a mammogram with MLO plus CC views. However, lower doses are possible with other protocols, said Dr.
