研究目的:

探讨一种基于MRI结合三维建模技术下建立的子宫内膜3D模型,量化残留功能性子宫内膜面积并对IUA准确分级的新方法,并探讨该模型形态学参数与妊娠的关系。  

Objectives of Study:

To explore a new method for quantifying residual functional endometrial area and accurately grading IUA based on MRI combined with three-dimensional modeling technology, and to explore the relationship between morphological parameters of the model and pregnancy.

Inclusion criteria

Women aged 18-35 who have fertility requirements, need hysteroscopy with complete data, and have follow-up conditions; Or combined with one or more of the following (1) History of uterine cavity operation, such as curettage, abortion, polyp removal, etc. (2) The intraday membrane of the trigger is less than 7mm

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

宫腔镜可直接观察子宫内膜形态、厚度、血管分布及损伤特征(如纤维化、瘢痕、粘连),并能在直视下进行靶向活检,获取病理学证据

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Hysteroscopy can directly observe endometrial morphology, thickness, vascular distribution and injury characteristics (such as fibrosis, scar, adhesion), and can perform targeted biopsy under direct vision to obtain pathological evidence

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

超声测量内膜厚度、血流参数;MRI对软组织分辨率高,可清晰显示内膜信号异常(如T2加权像低信号提示纤维化),评估深层肌层受累情况,并有多层图像数据

Index test:

Ultrasound measurement of intimal thickness and blood flow parameters; MRI has high resolution for soft tissue, can clearly show intimal signal abnormalities (such as T2-weighted images with low signal signal suggestive of fibrosis), evaluate deep muscle layer involvement and have multi-layer image data

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

有宫腔操作或手术史的女性;反复胚胎植入失败(RIF)或复发性流产(RPL)的18-35岁女性

例数:

Sample size:

23

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Women with a history of uterine cavity manipulation or surgery; Women aged 18-35 years with recurrent embryo implantation failure (RIF) or recurrent abortion (RPL)

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

慢性盆腔炎症或感染史女性;疑似内分泌或结构异常导致不孕的女性;

例数:

Sample size:

23

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Women with a history of chronic pelvic inflammation or infection; Women with suspected endocrine or structural abnormalities leading to infertility;
