OBJECTIVE: To evaluate the knowledge about diagnostic imaging methods among primary care and medical emergency physicians. MATERIALS AND METHODS: Study developed with 119 primary care and medical emergency physicians in Montes Claros, MG, Brazil, by means of a structured questionnaire about general knowledge and indications of imaging methods in common clinical settings. A rate of correct responses corresponding to > 80% was considered as satisfactory. The Poisson regression (PR) model was utilized in the data analysis. RESULTS: Among the 81 individuals who responded the questionnaire, 65% (n = 53) demonstrated to have satisfactory general knowledge and 44% (n = 36) gave correct responses regarding indications of imaging methods. Respectively, 65% (n = 53) and 51% (n = 41) of the respondents consider that radiography and computed tomography do not use ionizing radiation. The prevalence of a satisfactory general knowledge about imaging methods was associated with medical residency in the respondents' work field (PR = 4.55; IC 95%: 1.18-16.67; p-value: 0.03), while the prevalence of correct responses regarding indication of imaging methods was associated with the professional practice in primary health care (PR = 1.79; IC 95%: 1.16-2.70; p-value: 0.01). CONCLUSION: Major deficiencies were observed as regards the knowledge about imaging methods among physicians, with better results obtained by those involved in primary health care and by residents.

The present report is aimed at describing a rare case of cranial malformation - cloverleaf skull syndrome -, whose presence was noticed after the birth of a child with signs of abnormality. Imaging diagnosis methods such as computed tomography and conventional radiography were used to characterize the syndrome.
