Medical Oncology and Tumor Pharmacotherapy, 1991
A comparison is made of breast cancer mortality in women included in a mammography screening program, including those who refused to attend, and women who were not included--even those who underwent voluntary mammography. About 215,000 women in five different studies showed between 4 and 24% reduction of mortality; however, this was significant in only

Despite its technical advantages, early clinical trials comparing digital mammography with film mammography for screening have been somewhat disappointing. Digital mammography,however, is in its infancy and can be expected to improve more rapidly than film mammography. Some areas of improvement being observed now include the development of new detector

Clinical Obstetrics and Gynecology, 1989
Mammography is the tool of choice for evaluation of the breast. It is the immediate obligation of the obstetrician-gynecologist to increase the utilization of screening mammography. It is the immediate obligation of the radiologist to reduce the cost of mammography and to increase understanding of the postlumpectomy, postradiation therapy mammogram.

Contemporary Diagnostic Radiology, 1998
In digital mammography, the processes of image acquisition, display, and storage are separated, which allows optimization of each. Radiation transmitted through the breast is absorbed by an electronic detector, the response of which is faithful over a wide range of intensities.

Radiology, 1977
Ultrasound mammography was performed with unique, high resolution equipment which displays changes in acoustic properties of tissues through a calibrated gray scale. Color-coded isodensitometry was used to assist in the differential diagnosis. The rate of agreement between the ultrasound and pathological diagnoses was 86.7%.

Cancer, 1976
Tens of thousands of mammograms are performed daily in the United States. Accumulated radiation biologic data suggest that approximately 90-rad is the level of radition to the breast above which the incidence of cancer may be increase. A microdose system of roentgenography is described that provides better images at one-third to one-fifth the exposure ...

American Journal of Roentgenology, 1986
Over a 7-year period, 94 mammograms were performed for male breast disease. Indications included breast enlargement, tenderness, mass, and previous mastectomy. Fatty enlargement was easily diagnosed. Gynecomastia was unilateral in 28 of 40 cases and easily differentiated from malignancy in all but one patient in whom nipple retraction was present.

A blurred mass subtraction technique has been developed for mammography that will enhance small object contrast and visibility throughout the breast area. The procedure is easy to implement and requires no additional exposure. Perception of low-contrast objects is improved by eliminating extreme light and dark image areas. Contrast of structures within

Mammography is one of the most technically demanding examinations in radiology, and it requires X-ray technology designed specifi cally for the task. The pathology to be imaged ranges from small (20–100 μm) high density microcalcifications to ill-defi ned low contrast masses. These must be imaged against a background of mixed densities.

When evaluating mammograms, one looks for masses, areas of asymmetry or architectural distortion, and microcalcifications. This article discusses the imaging evaluation and the management of lesions found on screening and diagnostic mammography, with the focus on commonly encountered questions and dilemmas.
