We encountered no study conducted on the evaluation of prevertebral soft tissue (PVST) thickness by magnetic resonance imaging (MRI) during our literature search. Measuring PVST thickness by MRI in the cervical region of adult cases was aimed in the present retrospective study.
For the intended purpose, a total of 136 patients, composed of both males and females, with ages ranging from 20 to 69 years, in whom no pathology in the cervical prevertebral region was revealed by MRI modality implemented for various reasons, were included in the study.
The upper limit of normal for PVST thickness was measured in our study to be 10 mm, 7 mm and 20 mm at C1, C2-C3 and C6-C7 vertebral levels, respectively. The least variation in the measurements and standard deviations were obtained at C3-C4 vertebral levels. Upon making a comparison between the measured PVST thicknesses on the basis of gender, the measurements at C2,C4 and C7 were found to display significant difference, whereas that was not the case for the measurements obtained at the other levels.
Progressively widespread use of MRI for the traumas inflicting the cervical region makes it obligatory to specify normal values for the thickness of PVST measured by MRI.
在文献检索过程中，我们未发现有关通过磁共振成像（MRI）评估椎体前软组织（PVST）厚度的研究。本回顾性研究旨在通过MRI测量成年病例颈椎区域的PVST厚度。
为实现预期目的，本研究纳入了136例年龄在20至69岁之间的男女患者，这些患者因各种原因接受MRI检查，颈椎椎体前区域均未发现病变。
在本研究中，C1、C2-C3和C6-C7椎体水平PVST厚度的正常上限分别测得为10mm、7mm和20mm。在C3-C4椎体水平测量值的变化最小且标准差最小。基于性别对测量的PVST厚度进行比较时，发现C2、C4和C7水平的测量值存在显著差异，而其他水平的测量值则无显著差异。
MRI在颈椎创伤中的应用日益广泛，因此必须明确通过MRI测量的PVST厚度的正常值。
