    Pelvimetry can be performed on a computed tomographic (CT) scanner using anteroposterior and lateral scanned projection radiographs (Scout View) plus a single CT slice through the low pelvis. This technique yields accurate measurements of the maternal pelvis that do not need compensation for magnification. The fetal lie and presentation can be easily assessed, along with the fetal neck for hyperextension. In addition, the total radiation dose to both mother and fetus is significantly lower than with routine plain film pelvimetry. Since the procedure is quick, easy to perform and competitive in cost, CT pelvimetry should be the procedure of choice in those rare instances in which pelvimetry is indicated.

    Computed Tomography

    Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
    The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
