Abstract：
UNASSIGNED: Transperineal ultrasound (TPUS) is a vital examination method for diagnosing pelvic floor diseases. However, the quality of TPUS largely relies on the operator\'s experience, and there is a lack of studies on the evaluation of TPUS quality. Therefore, the objective of this study was to assess the quality of TPUS examinations in Chinese tertiary medical centers.
UNASSIGNED: This multicenter study conducted in 44 Chinese tertiary medical centers recruited postpartum women between September 2020 and September 2021. All participants underwent a standardized inquiry and TPUS examination. The participating centers were required to submit 5 parts of ultrasound data to the National Ultrasound Quality Control Center: 2-dimensional images at rest, 2-dimensional images at strain; 4-dimensional images of the levator ani hiatus; 4-dimensional images of the levator ani muscle; and 4-dimensional images of the anal sphincter. Quality assessment was performed by 2 experts with more than 5 years of experience in TPUS, and the reasons for nonqualification were stated.
UNASSIGNED: In this study, 31 hospitals that were distributed across 20 provinces in China were included, submitting 2,251 cases in total. The overall qualified rate ranged from 12.00% to 86.92%. In each part, the qualified rate of 2-dimensional images at rest, 2-dimensional images at straining, levator ani hiatus, levator ani muscle, and anal sphincter was 94.27% (2,122/2,251), 78.54% (1,768/2,251), 85.52% (1,925/2,251), 93.03% (2,094/2,251), and 88.09% (1,983/2,251), respectively. Most of the nonqualified images belonged to 2-dimensional images at strain, and the errors in image acquisition (221/483, 45.76%) and measurement (262/483, 54.24%) were the main reasons for nonqualification. For levator ani hiatus images, error in image acquisition (275/326, 84.36%) was the main reason for nonqualification. Reconstruction error was the most common reason for nonqualification for levator ani muscle (133/157, 84.71%) and anal sphincter images (133/268, 49.63%).
UNASSIGNED: This multicenter study assessed the quality of TPUS in tertiary medical centers in China and identified the common reasons for nonqualification in each part. These findings can aid in forming the basis for quality control management and training for TPUS.

摘要：
■经会阴超声（TPUS）是诊断盆底疾病的重要检查方法。然而,TPUS的质量在很大程度上取决于运营商的经验，缺乏对TPUS质量评价的研究。因此,本研究的目的是评估中国三级医疗中心TPUS检查的质量.
■这项在44个中国三级医疗中心进行的多中心研究在2020年9月至2021年9月期间招募了产后妇女。所有参与者都接受了标准化的询问和TPUS检查。要求参与中心向国家超声质量控制中心提交5部分超声数据：静息二维图像，应变时的2维图像；肛提肌间隙的4维图像；肛提肌的4维图像；肛门括约肌的4维图像。质量评估由2位在TPUS有5年以上经验的专家进行。并说明了不合格的原因。
■在这项研究中，包括分布在中国20个省的31家医院，共提交2,251起案件。总体合格率为12.00%~86.92%。在每一部分,静态二维图像的合格率，紧张时的二维图像，提肌肛门间隙，肛提肌,肛门括约肌占94.27%（2,122/2,251），78.54%（1,768/2,251），85.52%（1,925/2,251），93.03%（2,094/2,251），和88.09%（1,983/2,251），分别。大多数不合格的图像属于应变时的二维图像，图像采集误差(221/483，45.76%)和测量误差(262/483，54.24%)是不合格的主要原因。对于提肌肛门间隙图像，图像采集错误（275/326，84.36％）是不合格的主要原因。重建错误是肛提肌（133/157，84.71％）和肛门括约肌图像（133/268，49.63％）不合格的最常见原因。
■这项多中心研究评估了中国三级医疗中心的TPUS质量，并确定了每个部分不合格的常见原因。这些发现可以帮助形成TPUS质量控制管理和培训的基础。
