Added value of multiplanar reformation in the multidetector CT evaluation of the female pelvis: a pictorial review.

Although computed tomography (CT) is generally not the first-line imaging test of choice for the evaluation of female pelvic disorders, it is often the initial diagnostic examination performed in the emergency setting in patients who present with abdominal pain and nonspecific clinical symptoms. Multidetector CT coupled with reconstruction software permits isotropic voxel acquisition that can be used to generate two-dimensional multiplanar reformatted (MPR) images for evaluation of the female pelvis with no additional radiation exposure. Multidetector CT with MPR allows improved visualization of the normal anatomy and anatomic variants as well as greater diagnostic accuracy in the evaluation of the female pelvis. Although ultrasonography and magnetic resonance imaging remain the primary imaging modalities for the assessment of most female pelvic disorders, more accurate diagnosis of these disorders at multidetector CT may obviate additional imaging tests and allow more appropriate management.
