This prospective study aims to evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) in characterizing adnexal cystic lesions and differentiating benign from malignant lesions. MRI findings will be correlated with histopathology, surgical data, laboratory results, or follow-up imaging when surgery is not performed, to improve diagnostic confidence and guide appropriate patient management.
Adnexal cystic lesions are commonly encountered in gynecologic imaging and may represent a spectrum of benign and malignant conditions. While ultrasound is the first-line imaging modality due to its accessibility and safety, many adnexal masses remain indeterminate. Magnetic resonance imaging (MRI) provides superior soft-tissue contrast and multiparametric imaging, including T1-, T2-weighted sequences, diffusion-weighted imaging (DWI), and dynamic contrast-enhanced imaging (DCE), allowing better characterization of adnexal lesions. Features such as solid tissue, papillary projections, thick septa, and restricted diffusion help differentiate malignant from benign lesions. This prospective study at Sohag University Hospital will include 50 female patients with adnexal cystic lesions detected on ultrasound. MRI findings will be correlated with histopathology, surgical data, laboratory results (CA-125), or follow-up imaging when surgery is not performed. The study aims to assess the diagnostic accuracy of MRI in differentiating benign from malignant adnexal lesions and to improve clinical decision-making regarding patient management.
Study Type
OBSERVATIONAL
Enrollment
50
Magnetic resonance imaging (MRI) of the pelvis will be performed using 1.5T or 3T scanners with a phased-array pelvic coil. The protocol will include axial, sagittal, and coronal T2-weighted images, axial T1-weighted and fat-suppressed T1-weighted images, diffusion-weighted imaging with ADC maps, and dynamic contrast-enhanced sequences when clinically indicated and not contraindicated.

Diagnostic accuracy of MRI in characterization of adnexal cystic lesions
Assessment of the diagnostic performance of magnetic resonance imaging (MRI) in differentiating benign from malignant adnexal cystic lesions, using histopathology, intraoperative findings, or follow-up imaging as the reference standard. Diagnostic accuracy will be expressed in terms of sensitivity, specificity, and predictive values.
Time frame: From MRI examination until final diagnosis (surgery, histopathology, or follow-up imaging), up to 6 months
