Abstract

The purpose of this study was to evaluate the importance of automated lateral and medial temporal volume measurement technique for the early diagnosis of Alzheimer's disease (AD). A cross-sectional T1-weighted magnetic resonance image was obtained from 39 healthy adults and 39 patients with mild AD. The study demonstrates significant volume loss in the lateral temporal lobe (LTL) and medial temporal lobe (MTL) regions of the brain in early cases of AD, suggesting that volume loss could be used as a viable biomarker for mild AD diagnosis. Using a deep learning-based auto-segmentation network (CINet), the study accurately estimates the volumes of various LTL and MTL brain regions. Notably, higher volume loss is observed in the left MTL and LTL regions compared to the right, indicating an asymmetric impact in mild AD. The study underscores the significance of automated technique for AD diagnosis and monitoring disease progression, contributing valuable insights for potential early interventions.

Abstract Image

自动量化颞叶外侧和内侧容积,提高早期阿尔茨海默病诊断水平
本研究的目的是评估颞叶外侧和内侧容积自动测量技术对阿尔茨海默病(AD)早期诊断的重要性。研究人员采集了 39 名健康成人和 39 名轻度阿尔茨海默病患者的横断面 T1 加权磁共振图像。研究表明,在早期阿兹海默症病例中,大脑外侧颞叶(LTL)和内侧颞叶(MTL)区域的体积明显缩小,这表明体积缩小可作为诊断轻度阿兹海默症的可行生物标志物。该研究利用基于深度学习的自动分割网络(CINet),准确估算出了不同LTL和MTL脑区的体积。值得注意的是,与右侧相比,左侧 MTL 和 LTL 区域的体积损失更大,这表明轻度注意力缺失症的影响是不对称的。这项研究强调了自动化技术在诊断和监测AD疾病进展方面的重要意义,为潜在的早期干预措施提供了宝贵的见解。
