Diagnostic Reference Levels in Mammography in the Asian Context

Background: Breast cancer is the most frequent among female population globally. Therefore, early detection helpful for effective treatments and to reduce mortality rate. Mammography a radiological examination done with low-energy X-rays detect abnormalities in breast tissue. This study aims review literature evaluate techniques, protocols, conversion factors used determine diagnostic reference levels (DRLs); within Asian continent using both phantom- patient-based data.
 Methods: Related articles were systematically reviewed via Pub Med, Google scholar, freehand search aid of relevant terms. abstracts English screened, suitable selected after reviewing full-text. Four hundred thirty screened relevance, 12 selected.
 Results: The comprises four phantom-based eight studies. studies varied between types test subjects, factors, compression thickness, dose calculation protocols. obstructs continuing DRLs updates comparisons countries. Establishments countries are less than rest world. should be measured continuously, updated based on other clinical parameters patients.
 Conclusion: mammography from time different geographical locations Asia by following various techniques. But when compared regions world, there consideration establishing Asia. There standard protocols according advancements technology ensure radiation protection optimal absorbed appropriate image quality.
