Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

adnexal cystic lesions cohort

This group consists of female patients of all ages presenting to the Radiology Department at Sohag University Hospital with adnexal cystic lesions detected on ultrasound. Eligible participants have indeterminate or suspicious ultrasound findings and will undergo MRI for further characterization. MRI findings will be correlated with histopathology, surgical data, laboratory results, or follow-up imaging when surgery is not performed.

Magnetic Resonance Imaging

Intervention Type DIAGNOSTIC_TEST

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.
