Cardiac computed tomography (CT) is becoming increasingly important in noninvasive imaging. To meet this demand, there are a growing number of short training courses for cardiac CT. Whether such courses improve the knowledge and skills of participants is not known.
The concept of a two-day cardiac CT course consisting of introductory lectures, live patient examinations, and hands-on exercises for interpreting cardiac CT scans on workstations was analyzed using participant evaluations (scales from 1=excellent to 6=very poor). Participants rated their increase in knowledge and completed a validated questionnaire with 20 questions.
A total of 102 participants attended the courses. There were significant differences in the number of correctly answered test questions between cardiac CT experts and participants at the beginning of the course (91.5+/-6.3 % vs. 62.4+/-16.1% p<0.001). The number of questions answered correctly by the participants increased significantly after completion of the course (mean increase of 4 correctly answered questions, 81.8+/-11.4%. vs. 62.4+/-16.1% p<0.001). This objective increase in knowledge was in good agreement with participant self-assessments (76.4+/-12.6% vs. 81.8+/-11.4%). The quality of the course received good to very good scores, ranging from 1.8+/-0.7 for speed of presentation to 1.4+/-0.5 for lecturer competence. The score for overall course quality was 1.4+/-0.6.
A relatively short cardiac CT course can significantly improve the quantifiable knowledge of participants. The overall quality of the course was rated as very good.
心脏计算机断层扫描(CT)在无创成像中变得越来越重要。为满足这一需求,针对心脏CT的短期培训课程越来越多。但此类课程是否能提高参与者的知识和技能尚不清楚。
通过参与者评估(评分范围从1 =优秀到6 =非常差)分析了一个为期两天的心脏CT课程的概念,该课程包括入门讲座、对真实患者的检查以及在工作站上解读心脏CT扫描的实践练习。参与者对他们知识的增长进行评分,并完成一份有20个问题的有效问卷。
共有102名参与者参加了这些课程。在课程开始时,心脏CT专家和参与者正确回答测试问题的数量存在显著差异(91.5±6.3%对62.4±16.1%,p<0.001)。课程结束后,参与者正确回答的问题数量显著增加(平均增加4个正确回答的问题,81.8±11.4%对62.4±16.1%,p<0.001)。这种知识的客观增长与参与者的自我评估高度一致(76.4±12.6%对81.8±11.4%)。课程质量获得了良好到非常好的评分,从演示速度的1.8±0.7分到讲师能力的1.4±0.5分不等。课程整体质量评分为1.4±0.6。
一个相对较短的心脏CT课程可以显著提高参与者可量化的知识。课程的整体质量被评为非常好。
