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 handsearched diagnosis test in 6 kinds of published imaging journals having bigger influence in our country which included Chinese Journal of Radiology, Journal of Clinical Radiology, Journal of practical Radiology, Chinese Journal of Medical Imaging, Chinese Journal of Medical Imaging Technology and Journal of Radiological Practice. Then we evaluated each of the diagnosis test found out according to the International Standards.

Results: We totally searched more than 6 thousands article in which less than 9% were diagnosis tests. Of these diagnosis tests, less than 9% applied blind comparison with Gold Standard, less than 50% calculated sensitivity, specificity and accurate, and less than 10% calculated likelihood ratios, negative predictive value and positive predictive value

Conclusions: In China, the quality and quantity of the diagnosis tests applied in the specialty of imaging scientific study is far from meeting the clinical request. Improving methods of scientific studying and carrying on more diagnosis tests of high quality is of important significance to improving the diagnostic level of imaging.
