Rybicki said. ‘Our research demonstrated that if you use this model and contain the skull in your hands, there is no better way to plan the procedure.’ Each of the transplant recipients underwent preoperative CT with 3-D visualization.

The new equations represent an progress over currently available equations across the range of GFR and in relevant subgroups.
