Abstract

The purpose of this study was to demonstrate feasibility of intraurethral magnetic resonance imaging (MRI) for in vivo assessment of the female urethra and to determine the anatomy of the urethra and periurethral attachments as depicted using an endourethral MR coil. Twenty-three continent volunteers were studied with a 14F endourethral MR coil. Intraurethral MRI allowed detailed visualization and measurements of the muscular layers of the urethral sphincter and permitted the evaluation of supporting ligaments. This technique may become useful in the evaluation of anatomical defects associated with female urethral sphincter deficiency.

摘要

本研究的目的是证明尿道内磁共振成像（MRI）用于女性尿道活体评估的可行性，并确定使用尿道内MR线圈所显示的尿道及尿道周围附着结构的解剖情况。对23名控尿志愿者使用14F尿道内MR线圈进行了研究。尿道内MRI能够详细显示尿道括约肌的肌层并进行测量，还能对支撑韧带进行评估。这项技术在评估与女性尿道括约肌缺陷相关的解剖学缺陷方面可能会很有用。
