Bone subtraction 3D CT venography for the evaluation of cerebral veins and venous sinuses: imaging techniques, normal variations, and pathologic findings.
OBJECTIVE
Varying anatomic characteristics and clinical and radiologic manifestations are diagnostic challenges in the evaluation of the cerebral vein and of venous sinus diseases. The purpose of this article is to introduce bone subtraction CT venography and review normal variations and diseases involving the cerebral veins and venous sinuses.


CONCLUSIONS
Knowledge of the normal variations and pathologic findings will be helpful for the accurate diagnosis of diseases involving the cerebral venous system. Bone subtraction CT venography offers complete 3D visualization of the cerebral venous system and can be useful for the evaluation of the cerebral vein and venous sinus diseases.
