头颈CT血管成像AI辅助重建在医学影像技术专业实践教学中的应用
Application of AI-assisted reconstruction in head and neck CT angiography in medical imaging technology professional practice teaching
目的 探讨头颈CT血管成像(computed tomography angiography,CTA)人工智能(artificial intelligence,AI)辅助重建教学模式在提升医学影像技术专业学生CTA及重建技术教学中的应用价值。 方法 将2022年1月—2023年3月在首都医科大学宣武医院放射与核医学科实习的15名医学影像技术专业学生纳入对照组,采用传统规范化教学模式培训;将2024年1月—2025年3月同样在该科室实习的17名医学影像技术专业学生纳入试验组,采用AI自学结合规范化教学模式。两组分别通过理论考核、实际扫描操作考核、血管重建技能考核及满意度调查评价教学效果。 结果 总体上,试验组学生在理论考核、实际扫描操作考核及血管重建技能考核中得分均显著高于对照组(P<0.001),且后处理重建时间低于对照组(P<0.01)。在头颈血管定位、解剖结构识别、特定病变描述、狭窄程度评估、伪影识别分析、血管重建时间等后处理技能细化项目考核中,试验组各项得分也均高于对照组(P<0.01)。同时,试验组学生满意度评分均显著高于对照组[(96.35±1.17)分 vs (81.60±1.50)分,P<0.001],试验组学生反馈该教学模式在提升对头颈部血管的解剖认识、提升学习兴趣、提高学习效率以及提高专业水平方面有一定助力。 结论 AI辅助教学模式能够有效提升学生对头颈部CTA操作及血管重建技能的掌握,但不能取代传统教学方法,需两者有效结合,才能为医学影像技术专业教学实践提供有力支撑。
Objective To explore the application value of the artificial intelligence (AI) -assisted reconstruction teaching mode in head and neck computed tomography angiography (CTA) in improving the teaching of CTA scanning and reconstruction techniques for students majoring in imaging technology. Methods A total of 15 medical imaging technology students who interned in Department of Radiology and Nuclear Medicine, Xuanwu Hospital, Capital Medical University from January 2022 to March 2023 were included in the control group and trained using traditional teaching methods, while 17 medical imaging technology students who interned in tomography from January 2024 to March 2025 were included in the experimental group and were first self-taught with AI and then received standardized teaching training. The teaching effects of the two groups were evaluated through theoretical tests, practical scanning operation tests, vascular reconstruction skills tests, and satisfaction surveys. Results Overall, the experimental group scored significantly higher than the control group in theoretical assessment, practical scanning operation, and vascular post-processing reconstruction skills (P<0.001), and the post-processing reconstruction time was shorter than that of the control group (P<0.01). In the detailed post-processing skill assessment items such as head and neck vessel localization, anatomical structure identification, specific lesion description, stenosis degree evaluation, artifact recognition and analysis, and vascular reconstruction time, the scores of the experimental group were also significantly higher than those of the control group (P<0.01). Meanwhile, the satisfaction score of the experimental group was significantly higher than that of the control group [(96.35±1.17) points vs (81.60±1.50) points, P<0.001]. Students in the experimental group also provided feedback that this teaching model was helpful in improving the anatomical understanding of blood vessels in the head and neck region, enhancing learning interest, improving learning efficiency, and enhancing professional skills. Conclusion The AI-assisted teaching mode can effectively enhance students' mastery of head and neck CTA operation and vascular reconstruction skills, but it cannot replace traditional teaching methods. Only by effective combination of the two can provide favorable support for the teaching practice of medical imaging technology.
