目的:对比研究国产与进口彩色超声诊断仪在产前超声检查中的临床应用,探讨国产彩超在各级医院产前超声检查的可行性。方法:在7所不同级别医院,选用可以代表国产彩超先进性水平的彩超仪4台,分别定义为1号机、2号机、3号机及4号机,参照评价进口通用型飞利浦高端彩超为对比机;分别对产前行超声检查的210例胎儿所留存的图像进行临床对比评价及评分。结果:国产4台彩超评分结果分别为1号机87.75分,2号机96.20分,3号机81.31分,4号机84.90分;进口对比机105.0分。国产4台彩超评分结果与进口对比机相比均有统计学意义(t=3.03,t=3.18,t=2.90,t=3.23;P<0.05)。结论:国产彩超可以满足基层医院及二级医院日常工作需要的产前超声检查,但不能满足三级以上产前检查,且仍待提高。
Objective: To compare the clinical application of domestic and imported color ultrasonic diagnostic apparatus in prenatal ultrasonography and to explore the feasibility of prenatal ultrasound in domestic hospitals. Methods: In 7 different levels of hospitals, four color ultrasound machines that can represent the advanced level of domestic color Doppler ultrasound were selected, which were defined as No. 1, No. 2, No. 3 and No. 4, respectively. According to the evaluation of imported general-purpose Philips high-end color Doppler As contrast machine; respectively, prenatal ultrasound examination of 210 fetuses retained images for clinical comparative evaluation and score. Results: The results of four domestic color Doppler ultrasound scoring were 87.75 points on the 1st machine, 96.20 points on the 2nd machine, 81.31 points on the 3rd machine, 84.90 points on the 4th machine, and 105.0 points on the import comparison machine. The results of the four domestic color Doppler ultrasound scores were statistically significant compared with imported contrast machines (t = 3.03, t = 3.18, t = 2.90, t = 3.23; Conclusion: Domestic color Doppler ultrasound can meet the needs of primary hospitals and secondary hospitals for prenatal ultrasound examination, but can not meet the above three prenatal tests, and still need to be improved.
