Chinese American women have lower rates of mammography screening compared with non-Hispanic White women. Although the extent of perceived barriers, as conceptualized by the Health Belief Model, have been shown to distinguish between currently non-adherent Chinese American women who have ever and never had a mammogram, it is less clear which types of perceived barriers differentiate them. One hundred twenty-eight Chinese American women in the New York metropolitan area who had not had a mammogram in the past year completed baseline assessments for a mammography framing intervention study. Demographics, medical access variables, and perceived barriers to mammography (lack of access, lack of need for screening, and modesty) were used to predict mammography history (ever versus never screened). Fifty-five women (43%) reported having been screened at least once. A sequential logistic regression showed that English speaking ability and having health insurance significantly predicted mammography history. However, these control variables became non-significant when the three barrier factors were included in the final model. Women who reported a greater lack of access ( = 0.36, < .05) and greater lack of need ( = 0.27, < .01) were less likely to be ever screeners. Unexpectedly, women who reported greater modesty were more likely to be ever screeners ( = 4.78, < .001). The results suggest that interventions for Chinese American women should identify and target specific perceived barriers with consideration of previous adherence.

OBJECTIVE
The evaluation of the effect of a mammography decision aid (DA) designed for older women at risk for lower health literacy (LHL) on their knowledge of mammography's benefits and harms and decisional conflict.
METHODS
Using a pretest-posttest design, women > 75 years at risk for LHL reviewing a mammography DA before and after their [B] primary care provider visit. Women were recruited from an academic medical center and community health centers and clinics.
RESULTS
Of 147 eligible women approached, 43 participated. Receipt of the DA significantly affected knowledge of mammography's benefits and harms [B] (pre-test (M = 3.75, SD = 1.05) to post-test (M = 4.42, SD = 1.19), p = .03). Receipt of the DA did not significantly affect decisional conflict (pre-test (M = 3.10, SD = .97) to post-test (M = 3.23, SD = 1.02), p = .71, higher scores = lower decisional conflict). The majority of the women (97%) indicated that the DA was helpful.
CONCLUSIONS
Women found a mammography screening DA helpful and its use was associated with these women having increased knowledge of mammography's benefits and harms.
PRACTICE IMPLICATIONS
With the shift toward shared decision-making for women > 75 years, there is a need to engage women of all literacy levels to participate in these decisions and have tools such as the one tested in this study.

Comparative Study Review
OBJECTIVE
Digital full-field mammography has been used at the Department of Radiology of Charité Medical Center in Berlin since June 1999. This study compares the new digital technique with conventional mammography including a survey of its value in breast imaging and an outline of future prospects.
MATERIAL AND METHODS
More than 1,000 of a total of over 5,000 mammographies performed between June 1999 and April 2000 have been obtained using the digital full-field mammography system Senographe 2000D (GE Medical Systems). The digital mammograms were compared with previous conventional films and conventional mammographies performed during the same period (Philips UC Diagnost, Senographe DMRplus).
RESULTS
Digital mammographies were equal to conventional ones in all cases and seemed to be superior in detecting microcalcifications in dense glandular tissue. Adequate assessment was possible despite the lower spatial resolution compared to conventional mammography. Additional magnified images were obtained with both techniques for differentiating microcalcifications.
CONCLUSIONS
Digital full-field mammography appears to be at least equal to the conventional technique and even superior in some respects. In our experience, the lower spatial resolution of digital mammography has no major disadvantages. The digital system provides new options for electronic storage of mammograms, telemammography, and computer-aided diagnosis.

PURPOSE
To evaluate trends in mammography quality before and after the implementation of the Mammography Quality Standards Act (MQSA) of 1992 and to compare technical data collected in the United States with corresponding data obtained from the first survey of mammography facilities conducted in 1994-1995 in Canada.
MATERIALS AND METHODS
Data from MQSA inspections conducted in 1995-1997 were analyzed and compared with survey data on U.S. mammography facilities acquired before the MQSA. Technical indicators of mammography quality such as radiation dose phantom image score, film processing, and darkroom fog were analyzed.
RESULTS
In the United States, phantom image scores, along with other technical measures of performance such as film processing, darkroom fog, and x-ray beam quality, have improved continuously since 1985. The U.S. mean glandular dose has increased to 1.6 mGy compared with the Canadian dose of 1.1 mGy. The mean total phantom image score with artifact subtraction was 11.1 in Canada in 1994-1995 and 11.8 in the U.S. in 1997.
CONCLUSION
Mammography quality is better today than it has been at any other time in the United States. With the exception of radiation dose. Canadian technical measures of performance are comparable to measures before MQSA in the United States.

Clinical Trial
PURPOSE
To investigate whether informing patients about mammographic compression changed the anxiety and pain that they experience during mammography.
MATERIALS AND METHODS
Five hundred and one patients were enrolled in the study. Two hundred and fifty seven (51.3%) were informed before the procedure by written forms explaining the necessity of compression. The remaining 244 (48.7%) didn't get any pre-procedural information. All participants completed demographic form and Spielberger's State Anxiety Inventory while they were waiting for mammography. They marked the level of pain due to compression on a 100-mm visual analog scale (VAS) after the procedure. Chi square, Pearson's correlation and Student's t tests were used for statistical analyses.
RESULTS
We didn't find any significant difference between the anxiety scores of the informed (41.4+/-7.9) and uninformed (40.9+/-7.7) women, but the pain level was significantly lower in the informed group (16.5+/-22.4) than in the uninformed group (24.5+/-28.1). There was no statistically significant relationship between the anxiety and pain levels. Women who had recently felt tense and nervous or had a fear of breast cancer diagnosis had higher anxiety levels.
CONCLUSION
Our data shows that informing patients about examination decreases the level of pain due to mammographic compression, but does not alter the anxiety level. The main cause of anxiety appears to be the fear of a malignant diagnosis. Any intervention to decrease this fear may increase the compliance rates for screening mammography.

A poor-quality mammogram is worse than no mammogram. This is particularly true in the screening situation. Quality assurance in mammography is defined as all of the practices that monitor and improve the delivery of mammographic services, including technical performance of the equipment, personnel qualifications, patient interactions, communication, and follow-up. Quality control is the component of quality assurance focusing on the technical performance of mammography equipment. The effectiveness and success of screening mammography depend on consistent production of high-resolution, low-dose mammographic images and their accurate interpretation. This article describes the American College of Radiology's Mammography Accreditation Program as it relates to mammography quality assurance.

Rapidly increasing U.S. healthcare spending has been a hot topic over the past few decades. Imaging studies, including screening mammography, are possible targets for cost savings. Radiologists need to be more proactive and take charge by actively participating in the cost reduction conversation, improving the quality of care, providing patients with accurate cost estimates and educating patients along with clinicians on the value we have provided and can provide in the future.

Solid evidence shows that screening mammography contributes to a substantial reduction in mortality from breast cancer, but it is far from a perfect test. Estimates of overdetection of breast cancer, based on extrapolation of SEER data, may suffer from considerable uncertainty because of major assumptions required in such calculations and the difficulty in correcting for confounding factors such as lead time and demographic variations. Some of the charged language used and the extreme positions taken in the discussion of screening distract from coherent communication of the complex issues surrounding this topic. More balanced discussion would better serve the public.

Comparative Study
Image quality and radiation exposures of a mammographic technique using direct radiographic magnification at 2 X with a microfocal spot x-ray tube and a fast, double screen-film system were compared to those of conventional contact mammography with a rare-earth screen and molybdenum target tube. The results indicate that the magnification technique yields improved detection of microcalcifications and comparable visualization of soft-tissue details, with a large reduction in radiation exposure. This technique has demonstrated the feasibility of carrying out high-quality mammography with an entrance dose of 1.35 X 10(-3) Gy (135 mrad) for the average breast.
