Abstract: Objective To explore the application of information teaching methods based on the rain classroom platform in the PET/CT imaging diagnostic internship course. Methods In November 2022, a total of 77 undergraduate students of medical imaging from the 2019 class were selected as the research object, and they were divided into groups through simple randomization. The study group (n=39) adopted the information teaching method based on the Rain Classroom platform, and the control group (n=38) adopted traditional teaching methods. The teaching quality effects of the two groups of students were objectively compared through examination scores, and the subjective feedback of students on the teaching effectiveness were understood through a questionnaire survey. The chi square test, independent sample t-test were used to analyze the data. Results The theoretical assessment and operational skills assessment scores of the study group students were (85.05±7.43) points and (86.26±6.28) points, respectively, which were higher than the control group students' (81.05±4.98) points and (78.50±5.29) points, all P<0.05. The subjective teaching satisfaction of the study group students was 94.9% (37/39), which was higher than the control group's 68.4%(26/38), P=0.031. Conclusions The information teaching method based on the rain classroom platform has a good teaching effect in PET/CT imaging diagnosis internship courses, which is conducive to stimulating students' initiative and enthusiasm, and thus enhancing the quality of classroom teaching.
