FIG 1. Surgically induced intracranial contrast enhancement. Thirty minutes after a superficial cortical electrocoagulation has been performed, T1-weighted images (500/20/4) obtained after the IV administration of a paramagnetic contrast agent show intense enhancement at the edge of the electrocoagulation. The differentiation of this surgically induced intracranial contrast enhancement from tumor enhancement can be difficult.
A, Obtained 5 min after the IV administration of a paramagnetic contrast agent.
B, Obtained 15 min after the IV administration of a paramagnetic contrast agent.
