Background&Method: This study is conducted with an aim to Diagnostic Accuracy of Uterine Adenomyosis through TransvaginalSonography and MRI in Department of Radiology, Index Medical College Hospital and Research Centre, Indore.All the patients were explained about the study in detail including risks/benefits, outcome, procedure, etc. in their own language. A voluntary written informed consent was obtained from them for participation in the study. Result: Conclusion:The diagnosis of adenomyosis prior to treatment planning is very important. And efficient treatment planning is based on the accurate diagnosis and characterization of the lesion. Magnetic resonance imaging modality has a very high diagnostic accuracy in adenomyosis diagnosis along with its accurate characterization. But the cost is very high, reducing the accessibility by many patients. Another diagnostic modality is the transvaginalsonography for diagnosing and characterization of adenomyosis. Studies have supported that transvaginalsonography has comparable diagnostic accuracy to that of magnetic resonance. In our study we found that the sensitivity, positive predictive value and diagnostic accuracy of transvaginalsonography are high in comparison to magnetic resonance imaging, but has poor specificity and negative predictive value. We recommend the use of transvaginalsonography in diagnosis and characterization of adenomyosis, but in cases with inconclusive diagnosis, use of magnetic resonance imaging is highly recommended.
