Evaluating ultrasound methods for diagnosing uterine lesions

Ultrasound Evaluation of the Myometrium Using the MUSA Terminology, Comparison With Histology.

Universitaire Ziekenhuizen KU Leuven · NCT04990076

This study is testing if a new way of using ultrasound can help doctors tell the difference between benign and malignant uterine lesions in patients who are having surgery.

What this trial studies

This observational study aims to assess the diagnostic accuracy of the MUSA terminology in differentiating between various myometrial lesions greater than 1 cm, including benign and malignant conditions. Patients scheduled for hysterectomy due to myometrial pathology will undergo a systematic preoperative ultrasound scan, where around 50 ultrasound characteristics will be evaluated. The study also seeks to develop a predictive model to distinguish between benign and malignant lesions based on selected ultrasound features. The findings could enhance preoperative diagnostic capabilities for uterine conditions.

Who should consider this trial

Good fit: Ideal candidates are women scheduled for hysterectomy due to myometrial lesions larger than 1 cm.

Not a fit: Patients with myometrial lesions smaller than 10 mm or those with other concurrent gynecological pathologies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of diagnosing myometrial lesions, leading to better treatment decisions for patients.

How similar studies have performed: While the approach is based on established terminology, the specific application of MUSA terms in this context is novel and has not been extensively tested in prior studies.
