Evaluation and characterization of pelvic masses of gynecological origin b ultrasonongraphy and MRI reproductive age group.

Objective: To diagnostic accuracy of ultrasonongraphy and MRI for characterization of pelvic masses of gynecological origin in reproductive age group, with histopathology acting as the gold standard. Study Design: Cross-sectional. Setting: Department of Radiology, PAF Hospital Islamabad. Period: April 25th, 2021, to October 25th, 2021. Methods: In this investigation, non-probability consecutive sampling was utilized to collect data. A total of 220 women with pelvic mass were included in the study. Data regarding characterization of pelvic masses (malignant/benign) form ultrasound/MRI and histopathology was noted as per operational definition. Results: The study included participants aged 18-50, with a mean age of 31.6135.70 years, a mean parity of 3.130+1.37, and a mean duration of complaints of 7.186 +2.10 weeks. Ultrasound has shown sensitivity of 75.5%, specificity 88.8% and diagnostic accuracy by 83.2%, PPV 69% and NPV 88.3%. MRI has shown sensitivity of 83%, specificity 93.7% and diagnostic accuracy by 91%, PPV 83% and NPV 93.7% in characterization of pelvic masses. Conclusion: When sonographic characteristics of a pelvic tumor are inconclusive, MRI should be investigated for pathology investigation.
