[Helical CT pelvimetry: advantages of a low dose volume acquisition technique]

The authors evaluate the accuracy of a new CT pelvimetry technique that allows faster and low dose acquisition, and provides an axial view of the true conjugate as well as a 3D view of the maternal pelvis. Made possible by the availability of MDCT, this new technique may be a good alternative to standard CT pelvimetry even if MR pelvimetry still appears as the gold standard.
