A Study of the Sensitivity and Specificity of the Magnetic Resonance Imaging (MRI) Technique used in the Diagnosis of Endometriosis versus the Intraoperative Appearance Considered the Reference Standard in the Diagnosis of Endometriosis

Endometriosis is a gynecological pathology with chronic symptoms, which negatively affects the patient’s quality of life1. The prevalence of endometriosis in asymptomatic women is between 2% and 50%, depending on the populations studied and the method of diagnosis. The severity of the symptoms as well as the probability of diagnosing endometriosis increases with age9. Because endometriosis is a gynecological condition with a non-specific clinical picture, sometimes even asymptomatic, imaging technology can be considered the first line of diagnosis for this pathology. The main objective of this study is to evaluate the sensitivity and specificity of nuclear magnetic resonance imaging (MRI) used in the diagnosis of endometriotic lesions depending on their location, and compare the results obtained with the intraoperative appearance considered a reference standard in the diagnosis of endometriosis. Our study revealed the highest specificity for MRI in the case of endometriotic bladder invasion, respectively the highest sensitivity for endometriotic rectal nodules.
