Common imaging techniques in gynecology include ultrasound, MRI, and CT scans. Ultrasound is the first-line imaging tool due to its safety, accessibility, and ability to provide detailed images of the uterus, ovaries, and adnexa. MRI is used for more detailed imaging, especially in complex cases like deep infiltrating endometriosis or when malignancy is suspected. CT scans are less common but may be used in staging cancers or evaluating complex pelvic masses.
