Malaysia's mammography QA practice was surveyed based on the Malaysian Ministry of Health and the American College of Radiology (ACR) requirements. Data on mammography unit, processor, image receptor, exposure factors, mean glandular dose (MGD), sensitometry, image quality and viewbox luminance were obtained. Mean developer temperature and cycle time were 34.1 +/- 1.8degreesC and 107.7 +/- 33.2 seconds. Mean base+fog level, speed index and contrast index were 0.20+/-0.01, 1.20+/-0.01 and 1.33+/-0.26 respectively. Eighty-six percent of the fifty centres passed the image quality test while 12.5% complied with ACR recommended viewbox luminance. Average MGD was 1.0+/-0.4 mGy. Malaysia is on the right track for QA but with room for total quality improvement.
根据马来西亚卫生部和美国放射学会(ACR)的要求,对马来西亚的乳腺X线摄影质量保证实践进行了调查。获取了有关乳腺X线摄影设备、冲洗处理器、图像接收器、曝光参数、平均腺体剂量(MGD)、感光测定、图像质量和观片灯亮度的数据。显影剂平均温度和周期时间分别为34.1 +/- 1.8摄氏度和107.7 +/- 33.2秒。平均灰雾度、感光度指数和对比度指数分别为0.20 +/- 0.01、1.20 +/- 0.01和1.33 +/- 0.26。五十个中心中有86%通过了图像质量测试,而12.5%符合ACR推荐的观片灯亮度。平均MGD为1.0 +/- 0.4毫戈瑞。马来西亚在质量保证方面步入正轨,但仍有全面质量改进的空间。
