Functional imaging of the pelvic floor.

Area of Science:

• Radiology
• Pelvic Floor Imaging
• Women's Health

Background:

• Pelvic floor dysfunction and pelvic organ prolapse are significant health issues, particularly affecting parous women.
• Magnetic resonance imaging (MRI) plays a crucial role in assessing the extent of these conditions.
• Functional cine MRI is a key radiological method for dynamic pelvic floor evaluation.

Purpose of the Study:

• To review the utility of functional cine MRI in evaluating pelvic floor dysfunction and prolapse.
• To outline the standard methodology for functional cine MRI.
• To discuss the diagnostic capabilities and limitations of this imaging technique.

Main Methods:

• Utilizes high-field MRI systems.
• Employs fast gradient echo sequences in midsagittal planes.
• Involves patient positioning (supine or sitting) with rest and straining maneuvers.
• Analyzes images using the pubococcygeal reference line.

Main Results:

• Functional cine MRI is highly useful for evaluating organ descent and prolapse, with most studies confirming its efficacy.
• The method allows visualization of anterior, middle, and posterior pelvic compartments, aiding in enteroceles detection.
• It serves as a reliable tool for postoperative follow-up but is not indicated for isolated incontinence or equivocal clinical findings.

Conclusions:

• Functional cine MRI offers a promising approach for detecting organ descent and prolapse, especially in cases with unclear clinical findings.
• The integration of functional and morphological data provides novel insights into pelvic floor dynamics and structural interactions.
• This technique enhances the understanding of the complex interplay of pelvic floor structures.
