rolled CC view
Given that the rolled projections can be performed from any standard projection, the most commonly used is certainly the cranio-caudal one.
A rolled CC view It's performed to locate a lesion only visible in the cranio-caudal view, or when overlapped tissues in the standard view can simulate or partially conceal a lesion: changing of tissues distribution allows to determine whether or not its presence. When the lesion identified moves medially or laterally respect to the standard projection, it is possible to determine in which quadrant it is localized.
Positioning
The breast is positioned on the image receptor as for the cranio-caudal view, then is rotated medially or laterally around the axis of the nipple prior to applying compression.
Correctness criteria
Increased conspicuity of the structures concerned.
