BACKGROUND: Magnetic resonance imaging (MRI) is an expensive and commonly used technology with a variety of indications in @entity1 diagnosis and treatments. The aim of this study is to identify a comprehensive list of indications and contraindications for MRI in @entity1 with @entity1643 ( @entity1643 ) and to determine the appropriateness of using this technology in these @entity1 on the basis of this list. METHODS: A cross-sectional study was conducted in four radiographic centers in Tehran, Iran. A list of MRI indications and contraindications for @entity1643 was developed by review of documents and expert panel. A pre structured checklist was designed and incorporated into a structured form. All 100 consecutive @entity1 referring to four radiographic centers for performing MRI regarding @entity1643 completed the questionnaire. Chi-square, Fisher's Exact Test and logistic Regression were used to assess statistical significance. RESULTS: In this study, 187 @entity1 (46.7%) had an indication for MRI, but 186 @entity1 (46.5%) had no indication, 18 @entity1 (4.5%) had indication and contraindication at the same time and nine @entity1 (2.3%) had contraindication. Moreover, 71 @entity1 (17.8%) underwent MRI for @entity1643 during the past 2 years, of which 14 (19.7%) had normal results. @entity1 with complementary private insurance had a history of previous MRI about 20% more than other @entity1 (P = 0.018). There was a statistically significant relationship between complementary private insurance coverage and number of MRI performed (P = 0.006). CONCLUSIONS: About half of the @entity1 referring to radiographic centers with @entity1643 for MRI had no indication for this test.
