Objective To analyze the status of applying diagnostic test in imaging scientific study internationally and domestically, and to compare the application of the image diagnostic studies of our country with that of abroad.
Method We hand-searched the diagnosis tests published in the "Chinese Journal of Radiology", the most influential in China, and in "Radiology’’, the most influential abroad, from 1998 to 1999 respectively. Then we evaluated each of the diagnosis tests according to the international standards.
Results We searched 408 original articles in "Chinese Journal of Radiology" in which the diagnostic test articles were 12%, and 796 original articles in "Radiology" with the diagnostic test articles 23% from 1998 to 1999 respectively. In these diagnosis tests, by comparing the "Chinese journal of radiology" with the "Radiology", it was found that 19% applied blind comparison with Gold Standard, 28% calculated sensitivity, specificity and accuracy, 9% both calculated negative predictive value and positive predictive value and none calculated likelihood ratios in the former versus 64%, 57%, 33% and 26% and 3% respectivdy in the latter.
Conclusions Compared with the international level, both the quality and the quantity of the diagnosis tests applied in the specialty of imaging scientific study in China are much lower and far from meeting the clinical requirement. Improving the methods of scientific study and carrying on more diagnosis tests with high qualities are of important significance in improving the diagnostic level of imaging.
