China News Network, Hangzhou, April 13 (Qian Chenfei) On the 13th, the reporter learned from the Cancer Hospital Affiliated to the University of Chinese Academy of Sciences (Zhejiang Cancer Hospital) (hereinafter referred to as the National Cancer University Cancer Hospital) that the world's top 3D mammography equipment —— "Digital Breast Tomography Fusion Photography" (hereinafter referred to as 3D molybdenum target) has been successfully installed and has been put into clinical use. This is also the first 3D molybdenum target equipment introduced in Zhejiang, which will increase the detection rate of breast disease 34.4 %.
Breast cancer is one of the high incidence of tumors in Chinese women, and traditional X-ray photography is currently a common method for breast disease examination. "Early detection, early diagnosis, and early treatment of breast cancer can prolong the survival rate of patients. The sensitivity of 3D molybdenum target is higher, the positioning is more accurate, and it is more conducive to the early detection of tumors." Said Yang Hongjian, director of breast surgery at National Cancer University Cancer Hospital.

According to its introduction, the 3D molybdenum target can acquire breast images at different angles during a short scan, and reconstruct these independent images at a layer thickness of 1 mm into a series of tomographic images, just like the breast at a layer thickness of 1 mm By "cutting out" individual tomographic images, the doctor can view the breast tissue layer by layer.
Deng Xueying, the leader of the diagnostic group of the Radiology Department of the National University of Cancer Hospital, said that after detecting a suspected positive breast lesion, the traditional mammography often needs to recall the patient for a second examination, or to assist other detection methods (such as biopsy, etc.) to confirm the diagnosis. 3D molybdenum target can reduce tissue overlap, greatly reduce the probability of false positives and false negatives, and reduce the recall rate of patients.
It is reported that the current breast imaging examination methods include ultrasound examination, fully automatic breast volume ultrasound system, magnetic resonance and so on. In this regard, Chen Zhanhong, chief physician of the Department of Breast Cancer Internal Medicine at the National Cancer University Hospital, suggested that for routine medical examinations, women under the age of 40 are the first choice for ultrasound; women over 40 years of age are recommended for mammography every year. If there are suspicious lesions, lumps, nipple discharge, etc. in the past, you can also directly choose 3D molybdenum target or automatic breast ultrasound. (Finish)
