![]() ![]() ![]() The main advantages of MRI are the high contrast resolution and lack of ionizing radiation exposure. MRI is an essential problem-solving tool to determine the site of origin of a pelvic mass, to characterize an adnexal mass, and to detect local invasion. We describe MR signal intensity features and enhancement behaviour of ovarian lesions using pathologically proven examples from our institution. Using an imaging-guided approach based on morphological appearance, we classified adnexal masses into four main groups: unilocular cyst, multilocular cyst, cystic and solid, predominantly solid. Ovarian neoplasms may be benign, borderline or malignant. Primary ovarian tumours can be classified into three main categories according to tumour origin: epithelial, germ cell and sex cord-stromal tumours. Optimal assessment of adnexal masses requires a multidisciplinary approach, based on physical examination, laboratory tests and imaging techniques. BackgroundĬharacterization of ovarian lesions is of great importance in order to plan adequate therapeutic procedures, and may influence patient’s management. We propose a Magnetic Resonance Imaging (MRI) guided approach to differential diagnosis of ovarian tumours based on morphological appearance. ![]()
