This study analyzes the contribution of Computed Tomography (CT) in the detection and characterization of ovarian tumors, particularly malignant ones, to enhance the accuracy of preoperative diagnosis and postoperative follow-up, thereby optimizing therapeutic planning. This paper presents a retrospective study conducted on a group of 63 patients with ovarian tumors who were operated on at the Department of Gynecology of the Central University Emergency Military Hospital "Dr. Carol Davila" in Bucharest. The patients were investigated preoperatively using Computed Tomography to characterize the ovarian tumors and assess the sensitivity and specificity of the imaging diagnosis. Computed Tomography utilizing new multidetector technologies (MDCT) provides superior characterization of adnexal masses, with a sensitivity of at least 90% and a specificity of 80%. This imaging modality is recommended for the preoperative staging of ovarian cancer.
