用眼底多模态影像的纹理特征,预测1型糖尿病患者心血管风险等级。

Machine Learning Prediction of Cardiovascular Risk in Type 1 Diabetes Mellitus Using Radiomics Features from Multimodal Retinal Images

  • 从眼底照相、OCT和OCTA中提取纹理特征,结合机器学习分类风险
  • 仅用影像特征即达0.79~0.73的AUC,融合临床数据后提升至0.99
  • 无需全身数据也能识别极高危人群,适合糖尿病视网膜筛查场景

本研究旨在利用1型糖尿病患者的多模态眼底影像,构建机器学习算法以评估心血管风险,区分中度、高和极高风险。从眼底照相、光学相干断层扫描(OCT)及OCT血管成像(OCTA)图像中提取放射组学特征,单独或与临床数据结合训练模型。分析了597只眼(来自359名个体)的数据,仅使用放射组学特征的模型在区分中度风险与高/极高风险时达到0.79±0.03的AUC,区分高与极高风险时为0.73±0.07。加入临床变量后,所有指标均提升,区分中度风险的AUC达0.99±0.01,区分高与极高风险的AUC达0.95±0.02。对于极高心血管风险,结合OCT+OCTA与眼部数据的放射组学特征,即使不输入系统性数据,也获得0.89±0.02的AUC。结果表明,多模态眼底影像的放射组学特征可有效识别和分类心血管风险,凸显该眼组学方法在心血管风险评估中的潜力。

原文摘要 · Abstract (English)

This study aimed to develop a machine learning (ML) algorithm capable of determining cardiovascular risk in multimodal retinal images from patients with type 1 diabetes mellitus, distinguishing between moderate, high, and very high-risk levels. Radiomic features were extracted from fundus retinography, optical coherence tomography (OCT), and OCT angiography (OCTA) images. ML models were trained using these features either individually or combined with clinical data. A dataset of 597 eyes (359 individuals) was analyzed, and models trained only with radiomic features achieved AUC values of (0.79 $\pm$ 0.03) for identifying moderate risk cases from high and very high-risk cases, and (0.73 $\pm$ 0.07) for distinguishing between high and very high-risk cases. The addition of clinical variables improved all AUC values, reaching (0.99 $\pm$ 0.01) for identifying moderate risk cases and (0.95 $\pm$ 0.02) for differentiating between high and very high-risk cases. For very high CV risk, radiomics combined with OCT+OCTA metrics and ocular data achieved an AUC of (0.89 $\pm$ 0.02) without systemic data input. These results demonstrate that radiomic features obtained from multimodal retinal images are useful for discriminating and classifying CV risk labels, highlighting the potential of this oculomics approach for CV risk assessment.
