通过电影磁共振成像（cine-MRI）确定声带（VF）外展和内收评估的可行性。使用时间分辨率为0.7 s的轴向梯度回波采集，对5名健康受试者和9名单侧VF麻痹（UVFP）受试者进行VF的Cine-MRI。在10秒的安静呼吸和发声期间，用电影MRI连续成像VF。在一个单独的会话中重复扫描两次，然后以1周的间隔再次扫描。测定发声（VF发声不对称，VFPa）和呼吸（VF呼吸不对称，VFRa）期间VF位置的不对称性。在呼吸和发声之间的声门总面积的百分比减少（VF外展电位，VFAP）来衡量整体的流动性。使用非配对t检验比较组间差异。使用组内相关系数（ICC）评估定量指标的会话内、会话间和阅片者间的重复性。与健康参与者相比，UVFP患者的VF位置不对称性（VFPa和VFRa）更大（p= 0.012; p=0.001），总体移动性（VFAP）更低（p=0.008）。除会话间VFPa（0.44）外，所有指标的重复性ICC均良好，范围为0.82 - 0.95。电影MRI可用于评估VF外展和内收。导出的定量指标具有良好的可重复性。aEuro cent Cine-MRI用于评估声带（VF）活动度：外展和内收。aEuro cent新的定量指标来自VF位置和外展电位。aEuro cent Cine-MRI能够描述正常和异常VF活动度之间的差异。aEuro cent Cine-MRI导出的定量指标具有良好的可重复性。
Determine feasibility of vocal fold (VF) abduction and adduction assessment by cine magnetic resonance imaging (cine-MRI)Cine-MRI of the VF was performed on five healthy and nine unilateral VF paralysis (UVFP) participants using an axial gradient echo acquisition with temporal resolution of 0.7 s. VFs were continuously imaged with cine-MRI during a 10-s period of quiet respiration and phonation. Scanning was repeated twice within an individual session and then once again at a 1-week interval. Asymmetry of VF position during phonation (VF phonation asymmetry, VFPa) and respiration (VF respiration asymmetry, VFRa) was determined. Percentage reduction in total glottal area between respiration and phonation (VF abduction potential, VFAP) was derived to measure overall mobility. An un-paired t-test was used to compare differences between groups. Intra-session, inter-session and inter-reader repeatability of the quantitative metrics was evaluated using intraclass correlation coefficient (ICC).VF position asymmetry (VFPa and VFRa) was greater (p=0.012; p=0.001) and overall mobility (VFAP) was lower (p=0.008) in UVFP patients compared with healthy participants. ICC of repeatability of all metrics was good, ranged from 0.82 to 0.95 except for the inter-session VFPa (0.44).Cine-MRI is feasible for assessing VF abduction and adduction.
