CME Objectives and Tests 8(4)

The main purpose of the self-assessment program is to help Iranian radiologists and other specialists to update their professional knowledge and skills in clinical and research fields through studying the articles published in the Iranian Journal of Radiology (Iran J Radiol).
These series of Iran J Radiol tests are CME tests, authorized by the Ministry of Health and Medical Education. We suggest you study the articles before and after taking the test, and use other sources as well.
Please write your answers in the provided answer sheet and return it to the journal office. You can also download the answer sheet from, complete it, and E-mail it to
