概括
使用圆束计算机断层扫描 (CBCT) 放射学的机器学习模型可以预测关节 (TMJ) 盘位移. 这种方法为MRI提供了一种具有成本效益的替代方案,用于诊断不减少的圆盘位移 (DDWOR).
科学领域:
- 牙科 牙科是指牙科的专业.
- 放射学 放射学是一门学科.
- 人工智能的人工智能
背景情况:
- 关节 (TMJ) 盘位移的诊断严重依赖于MRI,由于成本和实用性,MRI存在可访问性挑战.
- 圆束计算断层扫描 (CBCT) 更容易获得,但缺乏MRI的诊断细节,用于TMJ盘位移.
研究的目的:
- 开发和评估机器学习 (ML) 模型,用于使用基于CBCT的放射学特征预测TMJ盘位移.
- 评估用CBCT和ML取代MRI的可行性,以诊断TMJ盘位移,特别是不减少的盘位移 (DDWOR).
主要方法:
- 从CBCT图像中提取了来自134名患者的247个下下的放射性特征,这些患者也接受了MRI扫描.
- 两个ML模型,随机森林 (RF) 和XGBoost,在三个分类实验中进行训练和比较.
- 实验涉及将正常状态,带有减少的圆盘位移 (DDWR) 和没有减少的圆盘位移 (DDWOR) 状态分类.
主要成果:
- 随机森林 (RF) 模型在所有实验中都表现优于XGBoost.
- 实验3,将DDWOR与其他条件区分开来,达到0.86 (RF) 和0.85 (XGBoost) 的最高AUC.
- 将所有三个组分类 (实验1) 产生了最低的准确性,AUC为0.63 (RF) 和0.59 (XGBoost).
结论:
- 使用CBCT放射学的ML模型显示出预测TMJ盘位移的前景.
- 这种人工智能驱动的方法可以作为辅助工具,特别是用于识别DDWOR,这需要仔细管理.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
