Functional MR imaging of the uterus

Area of Science:

• Radiology
• Gynecologic Imaging
• Functional MRI

Background:

• Recent advancements in Magnetic Resonance (MR) imaging facilitate functional uterine assessment.
• Uterine kinematic functions, assessed via myometrial contractility, are crucial in diagnosing gynecologic disorders.

Purpose of the Study:

• To review state-of-the-art functional MR imaging techniques for uterine assessment.
• To highlight the utility of cine, diffusion-weighted, and dynamic contrast-enhanced MR imaging in evaluating uterine conditions.

Main Methods:

• Cine MR imaging for evaluating uterine kinematic functions and myometrial contractility.
• Diffusion-weighted imaging (DWI) for detecting abnormal signal in pathologic foci based on molecular diffusion.
• Dynamic contrast-enhanced (DCE) MR imaging for tumor detection, staging, and monitoring therapeutic effects.

Main Results:

• Cine MR imaging assesses uterine contractility alterations in various gynecologic conditions.
• DWI provides information for evaluating malignant uterine conditions.
• DCE-MR imaging enhances tumor detection, local staging, and offers quantitative data for treatment monitoring and outcome prediction.

Conclusions:

• Functional MR imaging techniques are beneficial for elucidating various uterine conditions.
• Appropriate application of these advanced MR imaging methods provides a basis for future investigations in gynecologic imaging.
