调查安徽省超声产前筛查切面标准率及完整率基本情况，分析促进超声产前筛查和产前诊断服务标准化、同质化的措施。

安徽省内各产前筛查和（或）产前诊断医疗机构超声医学科于2024年4月在产前超声人工智能助手云平台上传2023年3月的筛查病例（包括至少2例早孕期、5例中孕期筛查病例），依据2022版超声产前筛查指南、产科超声规范化培训考核标准中国专家共识（2022版），对66家医院上传的图像进行智慧质控，质控内容包括：切面标准率、完整率，单切面得分，切面扣分项。

早孕期产前筛查病例共185例，缺失病例数91例，平均得分80.38分，切面标准率、完整率分别为40.7%、50.8%；得分较高切面分别是经侧脑室横切面（63.8%，118/185）和颈项透明层测量切面（58.9%，109/185），得分较低切面分别为脐带腹壁入口横切面（27.0%，50/185）和胎儿正中矢状切面（13.0%，24/185），漏检最多的是脐带腹壁入口横切面（71.9%，133/185）。中孕期产前筛查病例共373例，缺失病例数265例，平均得分85.38分，切面标准率、完整率分别为54.6%、29.0%；得分较高切面分别是胫腓骨长轴切面（85.8%，320/373）和上唇冠状切面（84.2%，314/373），得分较低切面分别为三血管气管切面（66.2%，247/373）和肱骨长轴切面（65.4%，244/373），漏检最多的是双肾水平横切面（16.1%，60/373）。

安徽省超声产前筛查切面标准率和完整率低是省内医院面临的共同问题，对产前超声检查医师进行规范化培训，增加检查前后的质量控制是有必要的。

To investigate the the of qualified sections and the rate of cases with qualified sections in prenatal ultrasound screening in Anhui Province, in order to promote the standardization and homogenization of prenatal ultrasound screening and prenatal diagnostic services.

The ultrasound medicine departments of all prenatal screening and/or prenatal diagnosis medical institutions in Anhui Province uploaded the cases screened in March 2023 to the prenatal ultrasound artificial intelligence assistant cloud platform in April 2024 (including at least 2 cases in the first trimester and 5 cases in the second trimester). According to the Practice guidelines for performance of prenatal ultrasound screening (2022) and Chinese expert consensus on assessment standards of obstetric ultrasound training program (2022 edition), intelligent quality control was conducted on the images uploaded by 66 hospitals. The quality control contents included the rate of qualified sections, the rate of cases with qualified sections, single section scores, and sections with lower scores.

A total of 185 cases of prenatal screening in the first trimester were encompassed. The number of cases with non-qualified sections was 91, with an average score of 80.38. The rate of qualified sections and the rate of cases with qualified sections were 40.7% and 50.8%, respectively. The sections obtaining higher scores were the transventricular section (63.8%, 118/185) and the view of nuchal translucency (58.9%, 109/185), while the sections obtaining lower scores were the transverse section of the cord insertion into the fetal abdomen (27.0%, 50/185) and the midsagittal view of the fetus (13.0%, 24/185). The section most often missed was the transverse section of the cord insertion into the fetal abdomen (71.9%, 133/185). A total of 373 cases of prenatal screening in the second trimester were encompassed. The number of cases with non-qualified sections was 265, with an average score of 85.38. The rate of qualified sections and the rate of cases with qualified sections were 54.6% and 29.0%, respectively. The sections obtaining higher scores were the longitudinal cross-section of the tibia and fibula (85.8%, 320/373) and the coronal section of the upper lip (84.2%, 314/373), while the sections obtaining lower scores were the three vessels and trachea view (66.2%, 247/373) and the longitudinal axial section of the humerus (65.4%, 244/373). The section most often missed was the transverse section of the kidneys (16.1%, 60/373).

The low standard rate and integrity rate of ultrasound prenatal screening section in Anhui Province are the common problems faced by hospitals in Anhui province. It is necessary to conduct standardized training for prenatal ultrasound doctors and strengthen quality control before and after the examination.
