Radiology is a useful tool for diagnosis and intervention in medical practice, and all the components within the teaching-learning process of this subject during undergraduate studies influence successful knowledge application.
This study aimed to describe the level of knowledge in radiology of students in the last two years of medical school and curricular characteristics of their courses in seven Latin American countries.
A multicenter cross-sectional study was carried out on medical students of 7 Latin American countries (Bolivia, Brazil, Colombia, Ecuador, Mexico, Paraguay, and Peru) in their final two years of medical school, using an online questionnaire validated by experts and adapted for each country that assessed knowledge and curricular characteristics in radiology subject. Scores were assigned according to the number of correct answers for the knowledge test. The T-test, and regression analysis with one-way ANOVA were used to search for relationships between the level of knowledge and other variables.
A total of 1514 medical students participated in this study. All countries had similar participation ( > 200); most participants were women 57.8%. The country with the highest knowledge score was Brazil. Male, sixth year (internship) and from public universities students had higher knowledge score ( < 0.05). Participants, who considered radiology more important, and who reported higher compliance with teaching staff with the proposed syllabus, and programmed classes, obtained better scores ( < 0.05).
Latin American medical students included in this study have a regular overall level of knowledge of Radiology, apparently influenced by curricular differences such as class and academic program compliance. Efforts to better understand and improve academic training are indispensable.
The study was subject to selection bias determined by non-probability convenience sampling. The questionnaire assessed only theoretical knowledge and the evaluation system was designed by the investigators.
放射学在医学实践中是一种有用的诊断和干预工具，本科阶段该学科教学-学习过程中的所有组成部分都影响着成功知识应用。
本研究旨在描述医学专业最后两年学生的放射学知识水平，并描述七个拉丁美洲国家该课程的课程特征。
对来自 7 个拉丁美洲国家（玻利维亚、巴西、哥伦比亚、厄瓜多尔、墨西哥、巴拉圭和秘鲁）的医学生进行了一项多中心横断面研究，这些学生处于医学专业的最后两年，使用了一种由专家验证并为每个国家改编的在线问卷，该问卷评估了放射学学科的知识和课程特征。知识测试的正确答案数量决定了分数。使用 T 检验和单因素方差分析的回归分析来搜索知识水平与其他变量之间的关系。
共有 1514 名医学生参加了这项研究。所有国家的参与率都相似（>200）；大多数参与者是女性（57.8%）。知识得分最高的国家是巴西。男性、第六年（实习）和来自公立大学的学生具有更高的知识得分（<0.05）。认为放射学更重要、报告对教学人员更遵守教学大纲和编程课程的学生获得了更高的分数（<0.05）。
参与这项研究的拉丁美洲医学生的放射学总体知识水平较为稳定，显然受到课程差异的影响，例如课程和学术计划的遵守情况。努力更好地理解和改进学术培训是必不可少的。
该研究受到非概率便利抽样确定的选择偏差的影响。问卷仅评估了理论知识，并且评估系统是由研究人员设计的。
