Patients with gynecologic problem are evaluated with a combination of clinical findings and diagnostic imaging including ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI). This imaging information plays an important role in the detection and characterization of gynecologic disease. US is commonly used as the first-line imaging modality. Although CT is often used for staging gynecologic malignancies and detecting recurrences, it can also be used for evaluating patients with acute pelvic pain, diagnosing conditions such as pelvic inflammatory disease, adnexal torsion and rupture of ovarian cysts, and differentiating from nongynecologic conditions such as appendicitis and colonic diverticulitis. Given its multiplanar capability and excellent soft tissue contrast, MRI has significant advantage in assessing the detailed anatomy of the female genital tract and can be served as a problem-solving tool when the findings at CT or US are equivocal or indeterminate. Common MRI indications include staging gynecologic malignancy, assessing benign uterine lesions, differentiating uterine versus ovarian masses, and characterizing adnexal masses and congenital anomalies of the female genital tract.
