INTRODUCTION. Innovative surgeons are successfully utilizing 3D/4D ultrasound imaging of the thyroid gland preoperatively. Through the use of 3D/4D ultrasound, the added benefit of visualizing the volume and structure of the thyroid can influence a surgeon’s approach and procedure to potentially diminish unexpected scenarios. Ultimately, in medicine, one learns anatomy to better understand the various clinical imaging modalities and/or the anatomical architecture to navigate surgical and invasive procedures. Viewing the thyroid gland using 3D/4D ultrasound can be valuable to physicians as well as students learning anatomy. The objective of this study was to investigate the perceptions of first-year medical students regarding the integration of 3D/4D ultrasound visualization of spatial anatomy of the thyroid gland during anatomical education. METHODS. 123 first-year medical students were introduced to 3D/4D ultrasound imaging of the thyroid gland through a detailed 20-minute tutorial taught in small group format. Students then practiced 3D/4D ultrasound imaging on volunteers and donor cadavers before assessment through acquisition and identification of thyroid gland on at least three instructor-verified images. After the tutorial, students practiced via peer-to-peer teaching averaging approximately 20-40 minutes of individual probe time. Each student also experienced an estimated one hour of passive learning during this time from watching their peers perform 3D/4D imaging on each other. A post-training survey was administered assessing student impression about 3D/4D ultrasound. SUMMARY. All students visualized the thyroid gland using 3D/4D ultrasound. Students revealed 88.0% strongly agreed or agreed 3D/4D ultrasound is useful revealing the thyroid gland and surrounding structures and 87.0% rated the experience “Very Easy” or “Easy”, demonstrating benefits and ease of use including 3D/4D ultrasound in anatomy courses. When asked, students felt 3D/4D ultrasound is useful in teaching the structure and surrounding anatomy of the thyroid gland, they overwhelmingly responded “Strongly Agree” or “Agree” (90.2%). 18 of the 123 student participants were assessed in an medical anatomy laboratory examination setting, where 89% of the students were able to correctly image and identify the thyroid gland using 3D/4D ultrasound. Students thought the 3D/4D probe was useful in learning the anatomy, but did not feel that it was easier to use compared to the 2D probe. CONCLUSION. This study revealed 3D/4D ultrasound was successfully used and preferred over 2D ultrasound by medical students during an anatomy dissection course to accurately identify the thyroid gland. Additionally, 3D/4D ultrasound may nurture and further reinforce stereostructural spatial relationships of the thyroid gland and other head and neck structures taught during anatomy dissection.
