Objective　to probe the potential application and advantages of heuristic method in the film-reading session of Imaging Radiology. Methods　66 eight-year program clinical medical ju-niors in the grade of 2008 to 2010 in Beijing University were selected as the subject and were evenly divided into two groups. Experimental group（n=33） was taught with heuristic method，in which the teacher ask questions and lead the students to find the way to solve problems in the way of clinical thinking mode. Control group（n=33） was taught with didactic method. The analysis of final examina-tion of radiology course and an anonymous questionnaire survey were carried out at the end of semester

and the questionnaire survey to the students in grade 2008 and 2009 was conducted again after 1 years of their clinical practice. Results　The score of students in experimental group were higher than those of control group (P=0.015

0.001

0.026 for the students in the grade of 2008

2009 and 2010 seperately). The two survey shows that the experimental group is better than the control group in the aspects of learning interest

clinical thinking ability

clinical application ability

solving difficult prob-lem ability and language expression ability. Conclusion　In the medical imaging practice teaching for clinical medical specialty undergraduate

the reasonable application of heuristic teaching

helps to im-prove students' learning enthusiasm and initiative

helps to cultivate medical students' ability of clinical application

and at the same time

can also improve teachers' teaching level.
