计算机辅助诊断 (CADx) 系统未经训练用于状状病变 (SSL),无法提高内镜师在识别这些息肉时的准确性. 然而,当准确时,CADx可以增强检测高塑性息肉和管状腺瘤的检测.
科学领域:
- 胃肠病学 胃肠病学
- 医疗成像医学成像
- 人工智能在医学中的应用
背景情况:
- 目前的计算机辅助诊断 (CADx) 系统缺乏对状状病变 (SSL) 的培训,将其错误地归类为超塑性息肉 (HP) 或管状腺瘤 (TA).
- 这种CADx的错误分类可能会影响内镜师对SSL的诊断准确性.
研究的目的:
- 评估当前CADx系统对内镜医生识别SSL的诊断准确度的影响,这些系统没有专门接受SSL培训.
- 评估CADx在HP和TA上的表现如何影响内镜师对这些病变的准确性.
主要方法:
- 17名内镜学家审查了115个多视频/图像 (33%的SSL,33%的HP,34%的TA).
- 多体呈现被随机分类,50%显示有CADx诊断,50%没有.
- 评估了CADx的性能:它将52.6%的SSL识别为HP和47.4%为TA,同时正确识别了68.4%的HP和82.1%的TA.
主要成果:
- 对于SSL识别,内镜的准确性与CADx显示或不显示没有显著差异 (64.1%与64.9%,p>0.05).
- 当内镜医生获得正确的CADx输出时,HP和TA的诊断准确性得到改善,但在不正确的CADx输出时,情况恶化.
- CADx错误地将SSL分类为HP (52.6%) 或TA (47.4%).
结论:
- 没有接受SSL识别培训的CADx系统不会显著改变内镜师对这些病变的准确性,即使有错误的诊断建议.
- 对HP和TA的准确CADx输出可以提高内镜医生的诊断准确性,对于这些特定的息肉类型.
