What requirements does the Ministry of Health have for radiation workers engaged in mammography?

Molybdenum target mammography is a diagnostic method that uses the physical properties of X-rays and different equal density values of human breast tissue to project two-dimensional images of breast onto X-ray film and observe them. Molybdenum target machine can be divided into analog type and full digital type. All-digital molybdenum target is rare in Sichuan, but specialized hospitals generally introduce all-digital molybdenum target machines.

Full digital mammography provides a reliable guarantee for the early detection of breast cancer with its high resolution and good contrast. It is the most reliable and effective diagnostic method for breast cancer recognized internationally at present.

All-digital breast camera has the characteristics of clear photos and appropriate contrast, and can accurately identify and locate. High-quality digital mammography has clear images. In displaying tiny lesions, small nodules with a diameter of 3MM and tiny calcification with a diameter less than 0. 1 mm can be displayed ... The sensitivity is over 97%, while the traditional photos are only about 8 1%. According to preliminary research, the success rate and accuracy of digital technology in stereotactic puncture of tiny lesions are over 96% and 94% respectively. The success rate of traditional technology is only 85%, and the accuracy is 8 1%.

For breast hyperplasia, young women are advised to use breast color Doppler ultrasound and molybdenum target examination over 35 years old.
