Abstract:
Objective To investigate the MR features of adenomyosis and its diagnostic value.Methods Forty-six patients with suspicious adenomyosis underwent preoperative ultrasound and MR exam.Inversion recovery sequence(IR)T 1-weighted images and turbo spin echo sequence(TSE)including T 1-weighted and T 2-weighted images were adopted.All patients were performed with contrast enhancement.Comparative analysis between MRI findings and pathology results was done. Results The diagnostic specificity,sensitivity and accuracy of MRI was 100%,94.74% and 97.14% respectively.The effect of MRI for diagnosis of adenomyosis was better than that of US significantly.All cases showed enlargement of uterus with regular contour.Diffuse and local thickening of junctional zone or low signal intensity lesion in outer myometrial layer was found on T 2-weighted images,sometimes bright foci observed in lesion on T 2-weighted images or on T 1-weighted images.Conclusion MRI has high value in gualitative diagnosis and localization of adenomyosis.It can be used as an important complementary method to ultrasound.
