Relief map of the upper cortical subarachnoid space ?

Hydrocephalus is a neurological disorder that usually results from obstruction of the cerebrospinal fluid outflow in the ventricles or in the subarachnoid space. Magnetic resonance imaging offers a great deal of information to specialists in the clinical diagnosis and treatment processes of hydrocephalus. Recently we have proposed a new magnetic resonance imaging sequence that significantly highlights the cerebrospinal fluid and a segmentation method for its space volumes assessment [3]. Those studies indicate us that the fluid distribution in the cortical subarachnoid space varies significantly, according to whether or not there is a pathology. However, visualization and analysis of the fluid distribution, particularly that of cortical sulci, remain difficult in three dimensions.
