Main problems for radiology teaching have always been less lectures and weaker imag-ing knowledge and lower interest of students in traditional Chinese medicine universities. Though flipped classroom has become the focus of education reform

and PACS system has become a platform in imaging diagnosis

it is rare to combine the two methods in radiology teaching. This paper mainly introduces features of flipped classroom and PACS system

analyzes the feasibility of combing the two teaching methods

and puts forward the teaching conception. Procedures are as follows. Before class

teachers design teaching ob-jective

prepare teaching material and make the list; students study before class in different groups. During class

students exchange their ideas

start inter-group discussion and use the PACS system for case studies; teachers instruct the key and difficult point. After class

the comprehensive evaluation is conducted. The combining teaching hopes to promote students' learning interest

improve their learning effectiveness

culti-vate their self-study ability and broaden their clinical minds. At the same time

this method also can provide experience for radiological teaching reform.
