craniocaudal view

(redirected from CC projection)

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.


the direction of entry of the x-ray beam. The beam enters at the cranial end of the part being examined and exits at the caudal end.

craniocaudal view
in a system of nomenclature of radiographic positioning used in animals, means the path that the beam takes from the x-ray tube to the film, passing from the head end of the animal towards its tail.

It also has been demonstrated that skin calcifications maintain a fixed relationship to each other on the same projection of the same breast from one mammogram to the next, or from one projection to a similar one, such as from a standard CC projection to a spot CC projection.
The CC projection is used to demonstrate the medial aspect of the breast and as much lateral tissue as possible.
2] Figure 1 illustrates a properly positioned CC projection.
This allows better imaging of the lateral aspect of very large breasts, which is not always possible with a standard CC projection.
To obtain the XCCL, the patient should be in a position similar to that used for the CC projection, except that he or she is rotated to emphasize the lateral aspect of the breast.
Mammographers may find it easier to perform a reverse CC projection on these patients.
Patient positioning for the modified CC projection is the same as tot the standard CC projection.
Large amounts of muscle tissue can make it difficult to obtain a useful CC projection of some male breasts.
To obtain the reverse CC projection, the mammographer rotates the C-arm 180 [degrees] then positions the patient facing the unit with one leg on each side of the tube head.
The inferior surface of the breast is then positioned onto the image receptor, much like the positioning for an upright CC projection.
Obtaining a reverse CC projection is very similar to obtaining a CC projection.
When positioning a patient in a wheelchair for the CC projection, the mammographer should determine whether the patient can wrap his or her arms around the underside of the cassette holder and hold its edges.
