Abstract:
In a case of cerebral infarction the lesions were isointense to slightly hyperintense in the T2-weighted MR images obtained approximately 2 weeks after the onset. Earlier (1 week after onset), they had been markedly hyperintense. The probably mechanisms behind this phenomenon, referred to as "MR fogging" are discussed.
