Reformatted computed tomography of the female pelvis: normal anatomy.

Axial computed tomography (CT) of the pelvis provides useful information in patients with gynaecological malignancies, both for initial staging, to follow disease progression and to assess response to treatment. Additional useful information may be available from reformatted coronal and sagittal images. Knowledge of normal anatomy is essential for correct interpretation of pathology. The anatomy and technique used to acquire the images are described in this paper.
