简要总结
Three-dimensional (3D) printed anatomic models are increasingly being developed for medical education. The investigators sought to compare the efficacy of a 3D printed model of the mediastinum as a study tool with standard textbooks for teaching medical trainees thoracic anatomy.
Participants were randomly assigned to either a lecture using a standard anatomy textbook or the same lecture along with a 3D printed model of the mediastinum. Participants took a timed pre-test and post-test, identifying 12 mediastinal structures on a prosected human cadaver. Independent and dependent t-tests were used to compare individual and group improvements respectively. A subjective assessment was also performed.

研究组 & 干预措施
Textbook Cohort
Trainees underwent a 10-minute lecture using two-dimensional (2D) images of the mediastinum selected from standard textbook resources. The lecture carefully reviewed the mediastinal anatomy reflected in the prosected cadaver and provided a variety of 2D axial, coronal, and sagittal images.
3D Model Cohort
Trainees underwent a 10-minute lecture using two-dimensional (2D) images of the mediastinum selected from standard textbook resources. The lecture carefully reviewed the mediastinal anatomy reflected in the prosected cadaver and provided a variety of 2D axial, coronal, and sagittal images. Upon completion of the didactic session, the 3D model cohort was provided with an additional 10-minute interactive lecture reviewing the same focused mediastinal anatomical structures using the 3D model.
