Objective　To review the practice of introducing nuclear medicine systematic courses into the standardized residency training in imaging specialty in recent years

and to explore the effect of nuclear medicine systematic courses on the training quality. Methods　A total of 105 residents participated in the training of nuclear medicine from 2015 to 2017 were enrolled in this study. During the training period

those who took the complete nuclear medicine systematic courses were assigned to the teaching group

and the other 52 residents who participated in the standardized residency training from 2012 to 2014 but not received the systematic courses were enrolled in the non-teaching group. The results of the completion examination

including the theoretical written test and the film reading skill test

were analyzed as the evaluation index to compare the differences between the results of two groups by the Mann-Whitney U test using SPSS 22.0. Results　The median scores of the theoretical test and the reading skill test in the teaching group were 93.52 (72.00-100.00) and 92.00 (70.00-98.00)

respectively; while

the corresponding scores in the non-teaching group were 88.00 (64.00-96.00) and 90.00 (60.00-96.00)

respectively. The scores of theoretical test and skill test in the teaching group were both significantly higher than those in the non-teaching group (P=0.005

P=0.001). Conclusion　It is necessary and feasible to carry out comprehensive nuclear medicine systematic courses in the standardized residency training in imaging specialty

which can improve the theoretical basis and clinical skills of students and help to improve the overall training quality.
