简要总结
In this prospective cohort study, the patients who were diagnosed with either uterine fibroid (control group) or adenomyosis (study group), were examined with transvaginal ultrasound and shear wave elastography. Definitive diagnosis was established by pelvic MRI. Shear wave elastography data of both groups were compared. Features of adenomyosis on transvaginal ultrasound were also recorded for study group.
详细描述
In this prospective cohort study, the patients who applied to the Gynecology and Infertility Outpatient Clinic in Istanbul University Faculty of Medicine between October 2018 and October 2021 due to abnormal uterine bleeding, pelvic pain, infertility were evaluated. The patients who were diagnosed with adenomyosis and uterine myoma according to clinical evaluation were included and grouped. Clinical diagnosis were confirmed with contrast enhanced pelvic magnetic resonance imaging. No histopathological confirmation were included in this study. 34 patients were included in adenomyosis group and 31 patients were included in myoma group. All patients were evaluated with shear wave elastography; 3 regions of interest were selected for each elastographic evaluation. Average shear values were determined automatically; then, minimum and maximum mean shear values were recorded accordingly. Elastography values of both groups were compared in order to detect any statistically significant difference between 2 groups. In addition to elastography evaluation, the compatibility of transvaginal ultrasound and magnetic resonance were evaluated.

研究组 & 干预措施
Adenomyosis
Patients who were diagnosed with adenomyosis according to pelvic MRI were examined with transvaginal ultrasound. Certain ultrasonographic features of adenomyosis ( asymmetrical uterine wall thickening, myometrial cysts, fan shaped lines and shadows, presence of irregular junctional zone, presence of clue sign, global enlargement) were recorded. Then the patients were examined with shear wave elastography. Maximum and minimum median shear wave values were recorded through the selected regions of interest.

Uterine Fibroid
Patients who were diagnosed with myoma uteri according to pelvic MRI were examined with transvaginal ultrasound. Then the patients were examined with shear wave elastography. Maximum and minimum median shear wave values were recorded through the selected regions of interest.

结局指标
主要结局
Elastography data of adenomyotic lesions and fibroids
时间窗: First we visualize the lesion in B-Mode ultrasound, then with the help of shear wave elastography, a color map is formed over the pathological lesion. We select 3 regions of interest to measure tissue stiffness. This takes about 15 minutes.
By using shear wave elastography, we can calculate the stiffness of selected region of uterine pathology. We use transvaginal ultrasound probe while performing shear wave elastography. The selected region of interest is defined as 10 mm circular area which is selected by the ultrasonographer. Stiffness of the tissue is calculated by elastography program which works by emitting acoustic radiofrequency impulses. These impulses creates transversely oriented shear waves which propagates through the tissue. The velocity of the shear waves is measured by the device and by using Young's modulus, shear wave elastography provides us a numerical value in kiloPascal. This value gives us important information regarding the stiffness of the tissue. For adenomyotic lesions and fibroids, shear wave elastography is performed and for each selected region of interest, a numerical value in kilopascal is given by the ultrasound and we aim to compare these data for adenomyosis and fibroid groups
次要结局
