阴道触觉成像（VTI）基于与手动触诊相似的原理。本研究的目的是评估在正常和脱垂条件下成像和组织弹性定量的新方法的临床适用性。研究对象包括31名正常和脱垂的妇女。组织弹性（杨氏模量）从所得3-D触觉图像中的空间梯度计算。正常情况下，前室和后室的组织弹性平均值分别为7.4±4.3 kPa和6.2±3.1 kPa。对于III期脱垂，前室和后室的组织弹性平均值分别为1.8±0.7 kPa和1.8±0.5 kPa。VTI可作为阴道三维成像和阴道组织弹性定量评估的手段，为进一步了解盆腔器官脱垂和手术治疗提供重要信息。
Vaginal tactile imaging (VTI) is based on principles similar to those of manual palpation. The objective of this study is to assess the clinical suitability of new approach for imaging and tissue elasticity quantification under normal and prolapse conditions. The study subjects included 31 women with normal and prolapse conditions. The tissue elasticity (Young’s modulus) was calculated from spatial gradients in the resulting 3-D tactile images. Average values for tissue elasticity for the anterior and posterior compartments for normal conditions were 7.4±4.3 kPa and 6.2±3.1 kPa respectively. For Stage III prolapse the average values for tissue elasticity for anterior and posterior compartments were 1.8±0.7 kPa and 1.8±0.5 kPa respectively. VTI may serve as a means for 3-D imaging of the vagina and a quantitative assessment of vaginal tissue elasticity, providing important information for furthering our understanding of pelvic organ prolapse and surgical treatment.
