11. Subarachnoid space
Comment: The T2-weighted magnetic resonance image shows the
ventricular system and cerebrospinal fluid in the subarachnoid space
(cisterns) as white. These images are useful for revealing pathology
such as infarcts, tumors, edema, and demyelination. A contrast agent
such as gadolinium can be used to delineate a tumor because of its
ability to leak across a disrupted blood-brain barrier.
