An evaluation of computer-assisted instruction in radiology.

The effectiveness of computer-assisted instruction in two radiologic topics was investigated. A group of fourth-year medical students received computer-assisted instruction while a control group received the same material by way of a conventional lecture. Each group was tested before and after instruction, and the group mean scores were compared. Student attitudes were elicited by questionnaire. Computer-assisted instruction was as effective as the lecture in improving the students' test performance. Subjectively, computer-assisted instruction was rated superior by the students because of its interactive nature. Applications of computer-assisted instruction in radiology education are discussed.
