背景情况:
- 术前诊断子宫介质瘤 (UMTs) 对于适当的手术管理至关重要.
- 在手术前区分恶性UMT与良性瘤仍然是一个挑战.
研究的目的:
- 为了外部验证以往基于MRI的专家共识算法,用于UMT诊断.
- 评估对UMT修改的基于MR的评分系统的准确性改进.
主要方法:
- 一个双中心的回顾性观察队列研究包括455名患有病理诊断的UMT的妇女,在盆腔后的MRI.

Histology of the Uterus
661
The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.

Magnetic Resonance Imaging
4.8K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
