Diffusion-Weighted Images and its Application in the Clinical Diagnostic Testing of Endometrial Focal Lesions
Background: Numerous endometrial disorders can create several difficulties for the radiologist due to the overlapping of imaging characteristics and diverse endometrial pathologies. The most frequently utilized imaging tool for diagnosing and characterizing endometrial focal lesions is magnetic resonance imaging (MRI) with diffusion weighted images (DWI). Objective: We conducted this study to determine the efficacy of MRI with DWI in improving the diagnostic accuracy of endometrial focal lesions, especially in the differential diagnosis of benign and malignant focal endometrial masses. Patients and Methods: This study recruited 36 women (21 postmenopausal and 15 premenopausal) who experienced vaginal bleeding and had endometrial thickness and focal endometrial lesions with a distinct echo pattern on ultrasound (US) examination. The age of patients was between 27 to 85 years, with an average of 45.2 years. Ethics Committee approval was obtained in addition to written informed consent from all included patients. Results: The 36 patients included in this study, were classified according to their lesions histopathological results; Benign group (15 lesions; 41.67%) and malignant group (21 lesions; 58.33%). The most common benign lesion was endometrial polyp (9/15) while the most common malignant lesion was endometrial carcinoma (21/21). In the current study MRI with diffusion could correctly diagnose 33 lesions out of 36 lesions, achieving (91.6%) sensitivity, (100%) specificity, (100%) positive predictive value (PPV), (95.6%) negative predictive value (NPV) and accuracy (97.05 %). Conclusion: Integrating DWI and ADC mapping at a high b value in pelvic MRI examination improves the sensitivity, specificity, and precision of diagnosing endometrial focal lesions.
