Difficult mammographic needle localizations: use of alternate orthogonal projections.
Lesions deep within the breast are occasionally visible on only one standard mammographic projection and are therefore difficult to localize preoperatively. Such abnormalities can often be visualized on two orthogonal 45 degrees oblique views. In these cases, needle localizations may be performed in a routine manner without computed tomography or stereotactic methods.
