INTRODUCTION
We investigated the changes in MRI T2 mapping values in subjects with carpal tunnel syndrome (CTS) compared to healthy controls.
METHODS
We enrolled 71 patients with CTS and 26 healthy controls. Median nerve T2 values were measured at the distal carpal tunnel, hamate bone, proximal carpal tunnel, and forearm levels. These were compared between patients and controls and correlated with median nerve cross-sectional area (CSA) and nerve conduction measurements.
RESULTS
The mean T2 values at the proximal carpal tunnel levels were higher in the CTS group (56.7 ms) than in the control group (51.2 ms, P = .02) and also were higher than at the distal carpal tunnel (51.0 ms, P < .001) and forearm levels (47.6 ms, P < .001). T2 values were not significantly associated with CSA or nerve conduction measurements.
DISCUSSION
T2 mapping of the carpal tunnel provides qualitative information on median nerve pathology but does not reflect CTS severity.
简介
我们研究了与健康对照组相比，腕管综合征（CTS）患者的 MRI T2 映射值的变化。
方法
我们招募了 71 名 CTS 患者和 26 名健康对照者。在腕管远侧、钩骨、腕管近侧和前臂水平测量正中神经 T2 值。将这些值与患者和对照组进行比较，并与正中神经横截面积（CSA）和神经传导测量值相关联。
结果
CTS 组近端腕管水平的平均 T2 值（56.7 ms）高于对照组（51.2 ms，P =.02），也高于腕管远侧（51.0 ms，P < .001）和前臂水平（47.6 ms，P < .001）。T2 值与 CSA 或神经传导测量值无显著相关性。
讨论
腕管 T2 映射可提供正中神经病变的定性信息，但不能反映 CTS 的严重程度。
