【摘要】：目的三维超声自动容积测量逐步在临床应用中表现出众多优点,并成为超声医学的一个重要发展方向。文中评估二维和三维超声对于单卵泡直径测量的一致性。方法对438枚单卵泡发育的卵泡分别进行二维超声和三维超声方法的测量,记录所得的二维直径、三维平均直径、三维虚拟球径,通过Bland-Altman Plot法对二维直径和三维平均直径、二维直径和三维虚拟球径分别进行一致性评估。结果在二维直径和三维平均直径2种测量方式对于单卵泡直径的测量的一致性分析中,差值的均数d=-1.06 mm,95%Lo A为(-4.82,2.70)mm,95%Lo A的95%CI为(-5.21,3.08),临床可接受一致性区间d±l0为(-3.56,1.44)mm,(-5.21,3.08)mm郺(-3.56,1.44)mm,一致性不佳;在二维直径和三维虚拟球径2种测量方式对于单卵泡直径的测量的一致性分析中,差值的均数d=-0.07 mm,95%Lo A为(-3.11,2.98)mm,95%Lo A的95%CI为(-3.43,3.29)mm,临床可接受一致性区间d±l0为(-2.57,2.43)mm,(-3.43,3.29)mm郺(-2.57,2.43)mm,一致性不佳。结论三维和二维超声测量方法对于单卵泡直径测量结果并不一致,但考虑到其在结果获得的客观性与精确性方面较二维超声仍然具有优势,可以为辅助生育技术提供更为精确的帮助。
[Abstract]:Objective Three-dimensional ultrasound automatic volume measurement has gradually shown many advantages in clinical application and has become an important development direction of ultrasound medicine. The consistency of two-dimensional and three-dimensional ultrasonography in measuring the diameter of single follicles was evaluated. Methods two dimensional ultrasound and three dimensional ultrasound were used to measure 438 follicles developed in single follicles. The two diameters, three dimensional mean diameters, three dimensional virtual sphere diameters were recorded. The two dimensional diameters and three dimensional mean diameters were measured by Bland-Altman Plot method. Two-dimensional diameter and three-dimensional virtual sphere diameter were evaluated respectively. Results in the consistency analysis of the measurement of single follicle diameters by two measuring methods of two dimensional diameters and three dimensional mean diameters, the mean value of the difference was -1.06 mm / 95 Lo A = -4.82 卤2.70 mm / 95 Lo A and 95%CI was -5.21 卤3.08 mm, and the clinical acceptable consistency interval d 卤10 was -3.561.44 mm ~ -5.21 mm ~ (-3.56) mm ~ (-1.44) mm, and the consistency was not good. In the conformance analysis of the measurement of single follicle diameter in two dimensional and three dimensional virtual spherical diameters, the mean value of the difference was dn- 0.07 mm / 95 Lo A = -3.11 卤2.98 mm and 95Lo A, the 95%CI was -3.43 卤3.29 mm, and the clinical acceptable consistency interval was -2.577 mm ~ (-3.43) mm ~ (-2.57) mm ~ (-1). Conclusion Three-dimensional and two-dimensional ultrasound methods are not consistent in the measurement of single follicle diameter, but they still have advantages over two-dimensional ultrasound in terms of objectivity and accuracy of the results. It can provide more precise help for assisted fertility technology.
