| Abstract:: |
| To ascertain the background and frequency of diagnostic medical X-ray procedures in China and provide the basis for regulatory oversight of such applications, a total of 557 medical institutions in 25 provinces or municipalities were surveyed by means of the optimally designed questionnaires and through stratified quota sampling. The numbers of procedures were calculated in terms of the type of procedures and the sex and age of examined patients. As a result, the frequencies of diagnostic X-ray procedures for 2016 in the country were derived using multiple linear regression analysis. The frequency of X-ray diagnosis in 10 provinces of China in 2016 was estimated to be 379-1 228 examinations per 1 000 population. Diagnostic X-ray applications have shown a rapid expansion in 2016 as compared with the period of "9th Five-Year Plan". It is very important to strengthen the regulation of medical diagnostic X-ray applications. |
