Abstract:
:An increase in the effective atomic number of blood is among the factors allowing or influencing the visualization of the major cerebral vessels on noncontrast CT. Bromine (atomic number, 50) attenuates 70 keV X-rays significantly and was responsible for a striking enhancement of the major cerebral vessels on the noncontrast CT in a child being treated for epilepsy. Although oral bromides are only occasionally used in the treatment of epilepsy, their use causes an increase in blood density and thus bromides need to be considered along with other etiologies (reviewed) that allow visualization of the major cerebral vessels on noncontrast CT.
