Magnetic resonance imaging in the evaluation of female pelvis

Abstract

Background: Magnetic resonance imaging (MRI) is an excellent noninvasive technique to evaluate the female pelvis due to its high spatial resolution, excellent tissue contrast, and multiplanar imaging capability. Radiologists often evaluate a wide range of pelvic masses during routine clinical practice. Objective: Aim and objective of the study is to evaluate the importance of MRI in the pelvic masses and to characterize the MRI findings in female pelvic masses. Materials and Methods: We prospectively performed MRI in our institute in 58 patients which detected pelvic pathologies or pelvic masses on clinical examination and/or ultrasonography. These lesions were examined for size, shape, signal intensity, character, and postcontrast enhancement. Secondary signs such as ascites, lymphadenopathy, and invasion of the adjacent organs were observed. Results: MRI was significantly superior to ultrasound in the evaluation of the tumor extension, myometrium invasion, detection of lymph nodes, and parametrical involvement anorectal carcinoma. Overall accuracy for detection of lesion by MRI was 97%, and sensitivity for the diagnosis of malignancy was 94%. Conclusion: MRI is an excellent investigation to evaluate the female pelvic masses due to its high spatial resolution, excellent tissue contrast, and multiplanar imaging capability. It is a very good modality for the tumor staging and follow-up of the cases. Certain key imaging features of uterine or adnexal pathologies on MRI are helpful in the specific diagnosis or narrow down the differential diagnosis. Characterization of uterine and ovarian tumors helps in the surgical planning.
