Magnetic resonance – a key imaging method for the characterization of ovarian cysts
Cystic formations of the ovaries are of particular clinical interest, as they occur very often in both reproductive and postmenopausal age. The basic imaging methods that are used in this type of pathology are ultrasound (US) and magnetic resonance (MR). Their role is related to the establishment of ovarian masses, their characterization and their differentiation from one another. From an image point of view, the cystic formations are divided into simple and complex ones and those with benign and malignant appearance. Тhe benign ones are significantly more common. Although US is the most commonly used imaging method in gynecology, there are some drawbacks, as many of the images of benign and malignant formations overlap. In addition, the field covering the US study is limited and does not provide information on the state of adjacent structures and organs. MR is highly informative and accurate (up to 91%), due to excellent spatial and tissue contrast imaging. It can provide additional diagnostic information about the presence of structures with different intensity characteristics such as fat and blood in the investigated formations, as well as definitively distinguishing benign from malignant. The application of the MR technique as a key diagnostic method for evaluating complex ovarian cysts aims to achieve a significant reduction in unnecessary surgical interventions.
