Abstract: Objective To explore the value of comparative imageology teaching mode based on picture archiving and communication system（PACS）in teaching of target area delineation in cervical cancer radiotherapy. Methods 46 students accepted standard training of clinical radiological oncology from Jan. 2016 to Dec. 2017 were divided into the experimental group（23 persons）and the control group （23 persons） randomly. The experimental group was taught by comparative imageology teaching mode based on PACS，and the control group was taught by lecture based learning mode. The application value was evaluated by test score and students′ satisfaction questionnaire. Results The image reading test score，practical test score and satisfaction score of the experimental group were （17. 11 ± 3. 10），（22. 73 ± 2. 53）and（8. 40 ± 1. 99），respectively；these indexes of the control group were（14. 52 ± 3. 69），（20. 79 ± 2. 18）and（7. 94 ± 2. 10），respectively；the difference was statistically significant（P < 0. 05）. Conclusion The comparative imageology teaching mode based on PACS can improve performances on image reading and target area delineation.
