本研究的目的是比较超声和MRI检测方法之间的一致性差异以及2名独立观察者之间的可靠性。在静息状态和肌肉收缩状态下，计算类内相关系数（ICC），由2名独立观察者评价2种诊断方法的一致性。我们还评估了2名观察员的评分员之间的可靠性。就盆膈生物学参数的评价而言，两种诊断方法的一致性为中等。盆膈区ICC为0.55（95% CI 0.35-0.71），前后径为0.48（95% CI 0.28-0.64），横径为0.43（95% CI 0.25-0.63）。会阴超声的超声检出值明显小于MRI。此外，这些差异随着盆膈面积的增加而增加。通过对静息状态下盆腔器官脱垂患者的盆膈进行评估，初步证实超声与MRI的一致性仅为中度。动态肌肉收缩状态下两种诊断方法的比较有待进一步探讨。
The aim of this study was to compare the consistency differences between ultrasound and MRI detection methods and the reliability between 2 independent observers. Under 2 kinds of states – the resting state and muscle contractions state – intra-class correlation coefficients (ICCs) were calculated and the consistency of 2 diagnostic methods was evaluated by 2 independent observers. We also assessed the interscorer reliability of the 2 observers. In terms of the evaluation of biological parameters of the pelvic diaphragm, the consistency of the 2 diagnostic methods was moderate. The ICC of pelvic diaphragm area was 0.55 (95% CI 0.35–0.71), anteroposterior diameter was 0.48 (95% CI 0.28–0.64), and transverse diameter was 0.43 (95% CI 0.25–0.63). The ultrasound detection values of the perineal ultrasound were significantly smaller than those of the MRI. In addition, these differences were increased with the rise of the pelvic diaphragm area. By evaluating the pelvic diaphragm in patients with pelvic organ prolapse in the resting state, it was preliminarily confirmed that the consistency of ultrasound and MRI was only moderate. The comparison of these 2 diagnostic methods under the dynamic muscle contraction state needs to be further explored.
