This study investigated the feasibility of a new image analysis technique (radiomics) on conventional MRI for the computer-aided diagnosis of Menière's disease.
A retrospective, multicentric diagnostic case-control study was performed. This study included 120 patients with unilateral or bilateral Menière's disease and 140 controls from four centers in the Netherlands and Belgium. Multiple radiomic features were extracted from conventional MRI scans and used to train a machine learning-based, multi-layer perceptron classification model to distinguish patients with Menière's disease from controls. The primary outcomes were accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the classification model.
The classification accuracy of the machine learning model on the test set was 82%, with a sensitivity of 83%, and a specificity of 82%. The positive and negative predictive values were 71%, and 90%, respectively.
The multi-layer perceptron classification model yielded a precise, high-diagnostic performance in identifying patients with Menière's disease based on radiomic features extracted from conventional T2-weighted MRI scans. In the future, radiomics might serve as a fast and noninvasive decision support system, next to clinical evaluation in the diagnosis of Menière's disease.
本研究旨在探讨一种新的图像分析技术(放射组学)在常规 MRI 上用于计算机辅助诊断梅尼埃病的可行性。
这是一项回顾性、多中心的诊断病例对照研究。本研究纳入了来自荷兰和比利时四个中心的 120 例单侧或双侧梅尼埃病患者和 140 例对照者。从常规 MRI 扫描中提取多个放射组学特征,并用于训练基于机器学习的多层感知器分类模型,以区分梅尼埃病患者与对照者。主要结局指标为分类模型的准确性、敏感度、特异度、阳性预测值和阴性预测值。
机器学习模型在测试集上的分类准确率为 82%,敏感度为 83%,特异度为 82%。阳性预测值和阴性预测值分别为 71%和 90%。
基于常规 T2 加权 MRI 扫描提取的放射组学特征,多层感知器分类模型在识别梅尼埃病患者方面具有较高的准确性和诊断性能。未来,放射组学可能成为一种快速、非侵入性的决策支持系统,与临床评估一起用于梅尼埃病的诊断。
