The choice of radiologic procedures in the diagnosis of breast disease.

We have reviewed the radiologic imaging procedures related to the investigation of breast lesions, particularly carcinoma. We discussed the choice of procedure in certain clinical situations and have made suggestions. Of the imaging methods, x-ray mammography is the most useful. Ultrasound is the next most useful; however, it is not acceptable for screening. The basis for breast cancer detection and diagnosis remains palpation and x-ray mammography. Ultrasound makes a substantial contribution to the diagnostic evaluation of certain lesions. Eventually, biopsy or surgery provides the final answer in those patients with possible lesions after these diagnostic procedures. In view of the high incidence of breast carcinoma, it would be useful for the practitioner dealing with these problems to establish for his practice a standard operating procedure for examination and referral of patients for breast screening and diagnosis as well as a system of follow-up to prevent patients from avoiding the screening and diagnostic process.
