Pseudo 3D DWI of the Female Pelvis: A Potential Means of Increasing Staging Accuracy

Martin D. Pickles¹, Lindsay W. Turnbull¹

DWI is increasingly used to stage gynaecological malignancies. Traditionally to acquire DWI a 2D approach has been implemented. To fully assess the uterus and cervix DWI acquired in the sagittal plane and perpendicular to the long axis of the uterus/cervix would be advantageous. Obviously, these additional sequences would lead to an increased total scan time. In this work we describe the acquisition of a 3D DWI sequence that not only provide a means of reformatting DWI in any desired plane but also facilitate registration/fusion with other imaging while maintaining an acceptable imaging time.
