“…Microcalcifications can be the sole sign of precancerous or of already infiltrating mammary carcinoma (Paterok et al 1993). Mainly because of their significance for the detection of early breast cancer, the imaging of these calcifications has been investigated by numerous authors during the last two decades.…”

“…Thus, at present it is still the most important breast imaging technique. Nevertheless x-ray mammography has some shortcomings in terms of sensitivity and specificity: on the one hand 5-15% of breast cancers are not visualized mammographically (Langer and de Paredes 1990, Bird et al 1992, Weinreb and Newstead 1994, and on the other hand the overall yield of breast cancers per number of breast biopsies recommended on the basis of screening mammograms ranges between roughly 10 and 50% (Baines et al 1986, Heywang 1988, Hurley and Kaldor 1992, Kerlikowske et al 1993, Paterok et al 1993, Weinreb and Newstead 1994. This explains the continuous search for other imaging methods, which could be suited for breast cancer screening and/or helpful in the differentiation between benign and malignant lesions.…”

Recent developments in breast imaging

A review of breast imaging has already appeared in 1982 in this journal. Consequently, the present article concentrates on a discussion of only those developments of a more recent nature. Although the emphasis is placed on the physical aspects of the different imaging methods concerned, the essential factors relating to the clinical background and the associated radiation risk are also outlined. The completeness of detail depends on the present clinical importance of the method under discussion. X-ray mammography, which is still the most important breast imaging technique and has proved to be an effective method for breast cancer screening, is therefore treated in greater detail. Since the early 1980s, ultrasound B-mode scanning has evolved to an indispensable adjunct to x-ray mammography. For Doppler sonography, diaphanography, contrast-enhanced MRI, CT and DSA, the visualization of a tumour depends essentially on the enhanced vascularity of the lesion. Whether this will prove to be a reliable indicator for malignancy remains to be shown in controlled clinical studies. Common to all imaging systems is the increasing use of digital methods for signal processing, which also offers the possibility of computer-aided diagnosis by texture analysis and pattern recognition.
