Цель исследования: сопоставить результаты измерения тела матки и эндометрия в 2D- и 3D-режимах.

Материал и методы

Материал и методы. Проведено обсервационное ретроспективное когортное исследование 154 женщин репродуктивного возраста без патологии миометрия и эндометрия. Для обследования органов малого таза использовали ультразвуковую систему Affiniti70 (Philips, Нидерланды) с мультичастотным 3D-полостным датчиком. Измеряли объем тела матки и объем эндометрия как в 2D-, так в 3D-режиме с последующим расчетом процентного отношения объема эндометрия к объему тела матки (скорректированный объем эндометрия).

Результаты

Результаты. Волюметрия тела матки в 3D-режиме имеет большие цифровые значения, чем при 2D-измерении, а относительная погрешность измерения составила 7,2%. Сила корреляционной связи оказалась весьма высокой: r = 0,91, р = 0,458. Согласно диаграмме Блэнда–Альтмана, почти все значения разницы показателей при парных измерениях попали в интервал ±1,96 SD 95%, низкий показатель средней разности свидетельствует о незначительном систематическом расхождения измерений, степень разброса показателей вполне допустимая. Объем эндометрия в 3D-режиме меньше, чем при 2D-режиме, относительная погрешность в 2D-режиме вне зависимости от фазы цикла составила -35,3%. Корреляция между двумя методами измерений высокая (r = 0,81), однако существенность различий между распределениями оказалась значимой (p < 0,05).

Заключение

Заключение. В практической работе допустимо применять значения объема тела матки, полученные в 2D-режиме, как аналогию волюметрии при 3D-реконструкции, в то время как объем эндометрия и скорректированный объем не могут использоваться как взаимно заменяемые методы измерения и расчета.

Objective

Objective: to compare the uterine corpus and endometrium volumes measured in 2D and 3D modes.

Material and methods

Material and methods. The observational retrospective cohort study included 154 women of reproductive age with no myometrial or endometrial pathology. Pelvic ultrasound was performed with the use of the Affiniti70 (Philips, Netherlands) with a multifrequency 3D intracavitary probe. The uterine corpus volume and endometrial volume were measured both in 2D and 3D modes, followed by a calculation of the percentage ratio of endometrial volume to uterine corpus volume (endometrial/uterine corporeal volume ratio (EV/UCV)).

Results

Results. The values of uterine corpus volume measured in 3D mode were higher than in 2D mode, with a relative measurement error of 7.2%. The strength of the correlation turned out to be very high (r = 0.91, p = 0.458). According to the Bland-Altman plot, almost all values of the volume difference in pairwise measurements fell within the interval ±1.96 SD 95%; a low average difference indicates a low systematic discrepancy in measurements, and the degree of value scatter is quite acceptable. The values of endometrium volume in 3D mode were lower than in 2D mode; the relative error in 2D mode, regardless of the cycle phase, was -35.3%. There was a strong correlation between the two measurement methods (r = 0.81), but the differences in allocations were significant (p<0.05).

Conclusion

Conclusion. It is permissible to use the values of the uterine corpus volume obtained in 2D mode as an analogue of 3D mode volume in routine practice, while it is not acceptable in the assessment of endometrium volume and EV/UCV.
