MR Imaging of Ovarian Masses

Abstract Objectives The use of magnetic resonance (MR) imaging in differentiation between benign and malignant adnexal masses in children and adolescents might be of great value in the diagnostic workup of sonographically indeterminate masses, since preserving fertility is of particular importance in this population. This systematic review evaluates the diagnostic value of MR imaging in children with an ovarian mass. Methods The review was made according to the PRISMA Statement. PubMed and EMBASE were systematically searched for studies on the use of MR imaging in differential diagnosis of ovarian masses in both adult women and children from 2008 to 2018. Results Sixteen paediatric and 18 adult studies were included. In the included studies, MR imaging has shown good diagnostic performance in differentiating between benign and malignant ovarian masses. MR imaging techniques including diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) imaging seem to further improve the diagnostic performance. Conclusion The addition of DWI with apparent diffusion coefficient (ADC) values measured in enhancing components of solid lesions and DCE imaging may further increase the good diagnostic performance of MR imaging in the pre-operative differentiation between benign and malignant ovarian masses by increasing specificity. Prospective age-specific studies are needed to confirm the high diagnostic performance of MR imaging in children and adolescents with a sonographically indeterminate ovarian mass. Key Points • MR imaging, based on several morphological features, is of good diagnostic performance in differentiating between benign and malignant ovarian masses. Sensitivity and specificity varied between 84.8 to 100% and 20.0 to 98.4%, respectively. • MR imaging techniques like diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) imaging seem to improve the diagnostic performance. • Specific studies in children and adolescents with ovarian masses are required to confirm the suggested increased diagnostic performance of DWI and DCE in this population.

Ovarian Masses

Objectives: Aim of my study is to determine the diagnostic accuracy of MRI in characterization of indeterminate ovarian masses on Doppler ultrasound (US) of pelvis while keeping histopathology as gold standard. Study Design: Cross sectional (validation) study. Setting: Radiology Department of Allied Hospital Faisalabad. Period: From January 2015 to December 2016. Material and Methods: Approval was taken from institutional ethical committee, a total of 91 patients were enrolled in this study. All the patients found to have indeterminate ovarian mass on sonography and Doppler US were examined with MR imaging performed on a 1.5-T Philips MR imaging unit in the radiology department Allied Hospital Faisalabad. The interval between Doppler US and MRI pelvis was about 7 to 10 days. Histopathology was taken as gold standard for final diagnosis and in determining the diagnostic accuracy of MRI. Results: All women having a mean age of 42 years (range, 15–85 years) who found to have indeterminate ovarian masses on Doppler US were included in the study. There were 71.4% benign and 28.6% malignant cases found on MRI while on histopathology 77% masses were benign and 23% malignant. The sensitivity and specificity of MRI in determining adnexal masses in our study is 100% & 93.86% Conclusion: MRI is ideal imaging modality for characterization of indeterminate ovarian masses. Magnetic resonance imaging is found to be quiet helpful in characterization of ovarian masses where sonography and Doppler US are not helpful.
