摘要

本研究旨在评估正常唾液腺和急性颌下腺炎（SS）的表观扩散系数（ADC）值。这项回顾性研究纳入了2018年2月至2022年5月期间在日本大学牙科学院接受磁共振成像（MRI）检查的22名患者。对急性 SS 组和对照组的 ADC 值进行了比较。经 Shapiro-Wilk 检验确认为非正态性的数据采用 Mann-Whitney U 检验、Spearman 相关系数和接收器操作特征（ROC）曲线进行分析。平均 ADC 值为 1.03 ± 0.正常组和急性 SS 组的 ADC 平均值分别为 1.03 ± 0.09 × 10-3 和 1.22 ± 0.17 × 10-3 mm2/s（p < 0.001）。ROC分析表明，ADC值为1.1的临界值可将急性SS与正常人区分开来。

Efficacy of apparent diffusion coefficient values for normal submandibular glands and acute submandibular sialadenitis

This study aimed to assess the apparent diffusion coefficient (ADC) values of normal salivary glands and acute submandibular sialadenitis (SS).This retrospective study included 22 patients who underwent magnetic resonance imaging (MRI) at the Nihon University School of Dentistry between February 2018 and May 2022. ADC values were compared between the acute SS and control group. Data with non‐normality confirmed by Shapiro–Wilk test was analyzed using the Mann–Whitney U test, Spearman's correlation coefficient, and a receiver operating characteristic (ROC) curve. Statistical significance was set at p < 0.05.The mean ADC values were 1.03 ± 0. 09 × 10−3 and 1.22 ± 0.17 × 10−3 mm2/s in the normal and acute SS groups, respectively (p < 0.001). ROC analysis revealed a cutoff ADC value of 1.1 for distinguishing acute SS from the normal.These findings suggest that ADC values are useful for the quantitative assessment of acute SS.
