Summary
Magnetic resonance imaging (MRI) effectively differentiates uterine malformations in infertile patients. While highly sensitive, its specificity is lower for partial septate uteri compared to surgical methods.
Area of Science:
- Reproductive Medicine
- Diagnostic Imaging
- Gynecologic Surgery
Background:
- Uterine malformations are associated with infertility.
- Accurate classification is crucial for appropriate management.
- Hysterosalpingography (HSG) can suggest bifid uterus but lacks detailed classification.
Purpose of the Study:
- To evaluate the capability of magnetic resonance imaging (MRI) in differentiating various classes of uterine malformations.
- To compare MRI accuracy with surgical findings in infertile patients diagnosed with bifid uterus via HSG.
Main Methods:
- Retrospective analysis of 18 infertile patients with HSG-diagnosed bifid uterus.
- All patients underwent MRI followed by laparoscopy or laparotomy.
- MRI findings were compared with surgical diagnoses for accuracy assessment.
Main Results:
- MRI correctly identified all bicornuate and didelphic uteri.
- MRI identified 9 out of 12 partial septate uteri and both complete septate uteri.
- Sensitivity for cervical prolongation of the spur was 100% with 78.6% specificity.
Conclusions:
- MRI is a valuable, non-invasive tool for classifying uterine malformations.
- MRI offers advantages over surgery in terms of cost and invasiveness.
- MRI limitations include lack of information on tubal conditions and minimal endometriosis.
