Abstract:
Objective To analyze the status quo of applying diagnosis test in imaging scientific study in China, and to see whether reliable diagnosis can be provided to clinicians for accurate guidance of clinical management. Method We manually looked up diagnosis tests published in 1979～1999 "Chinese Journal of Radiology" that is quite influential in our country. Then we evaluated each of these diagnosis tests according to the International Standards. Results We totally searched 2 888 articles in which only 9% were diagnosis tests. Of these diagnosis tests, only 8.9% applied blind comparison with Gold Standard, 24% calculated sensitivity, specificity and accuracy in the same time. And only 0.5%?6% and 5.7% respectively calculated likelihood ratios, negative predictive value and positive predictive value. Conclusion In China, the quality and quantity of the diagnosis tests applied in the specialty of imaging scientific study is far from meeting the clinical demand. Improving methods of scientific study and carrying on more diagnosis tests of high quality are of important significance to improving the diagnostic level of imaging.
