Introduction: Endometriosis is an important cause for abdominal and pelvic pain in young women. It occurs due to the presence of functional endometrial tissue outside the uterine cavity. Ultrasonography and magnetic resonance imaging (MRI) are noninvasive and accurate diagnostic modalities for evaluation of ovarian and deep endometriosis.
Aim: To compare and assess the diagnostic accuracy of ultrasonography and MRI for evaluation of endometriosis.
Materials and methods: A prospective study was done on 40 patients sent to the radiology department in our tertiary-care hospital over a period of 2 years with clinical suspicion of endometriosis. These patients were evaluated on ultrasonography, followed by MRI scan for the location and extent of disease. The sensitivity and specificity of diagnostic modalities were calculated.
Results: The sensitivity and specificity of ultrasound for diagnosing ovarian endometriosis (endometriomas) were 90.62 and 75.00%, respectively, and that of MRI were 93.94 and 85.71%, respectively. The sensitivity and specificity of ultrasound for diagnosing deep endometriosis (involving uterosacral ligament) were 25 and 97.30%, respectively, and that of MRI were 75.0 and 100%, respectively. The sensitivity and specificity of ultrasound for diagnosing scar endometriosis were 66.67 and 97.30%, respectively, and that of MRI were each 100%, respectively. The sensitivity and specificity of ultrasound for diagnosing tubal endometriosis were 50.00 and 97.37%, respectively, and that of MRI were each 100%, respectively. The findings of ultrasonography and MRI for evaluation of endometriosis were also correlated with histopathology.
Conclusion: Both ultrasonography and MRI are comparable modalities for evaluation of ovarian, scar site, and tubal endometriosis; however, MRI is the most useful and better imaging modality for evaluation of indeterminate cases and deep endometriosis.
