Radiographic imaging techniques for the diagnosis of abnormal uterine bleeding

Area of Science:

• Gynecologic imaging
• Diagnostic ultrasound
• Minimally invasive procedures

Background:

• Transvaginal ultrasound (TVUS) is limited in visualizing the endometrial cavity.
• Saline infusion sonohysterography (SIS) was developed to improve TVUS evaluation.
• Gynecologists face challenges in providing cost-effective, minimally invasive diagnostics for menstrual dysfunction.

Observation:

• SIS provides a clear, enhanced view of the endomyometrial complex, differentiating focal and global endometrial pathology.
• Saline infusion improves the sensitivity of ultrasound for detecting endometrial abnormalities.
• SIS is a safe, efficient, convenient, and well-tolerated office procedure, superior to D&C or hysteroscopy for many endometrial evaluations.

Findings:

• SIS is the most important imaging modality for endometrial pathology, offering benefits like minimal patient discomfort and better understanding of intrauterine pathology.
• In cases where TVUS or SIS is indeterminate for fibroid location or adenomyosis, MR imaging is a valuable tool.
• MR imaging reliably localizes pelvic pathology, differentiates uterine anatomy, and aids in surgical planning, potentially obviating hysterectomy for submucosal fibroids.

Implications:

• SIS offers a cost-effective, minimally invasive approach for evaluating endometrial abnormalities and guiding therapy.
• MR imaging serves as a crucial triage tool when ultrasound findings are inconclusive, influencing surgical route and planning.
• Integrating SIS and MR imaging into clinical algorithms optimizes patient care for abnormal uterine bleeding and related conditions.
