Held in conjuction with the American Society of Neuroradiology.
The IHIWG (International Hydrocephalus Imaging Working Group) consists of neuroradiologists, neurologists, neurosurgeons, engineers and basic scientists who meet twice a year in conjunction with ASNR and the ISHCSF (InternationalSociety for Hydrocephalus and CSF Disorders). The meeting will address all forms of hydrocephalus with emphasis on imaging NPH, including phase contrast techniques to measure aqueductal CSF flow, DESH (Disproportionately Enlarged Subarachnoid Space Hydrocephalus), and TimeSLIP to predict response to shunting. Additionally, the Study Group compares these noninvasive MR-based techniques to the more invasive intracranial pressure monitoring, saline infusion, high-volume tap test and external lumbar drainage. CSF production and resorption, role of aquaporins, and CSF flow measurements to study Chiari I malformations as well as potential sources of error in measurements are reviewed. Recent meetings have had focused sessions on MRI measurement of connectivity, tractography, elastography and evolving concepts such as the “glymphatic system” and the VIIP (Visual Impairment and Intracranial Pressure) syndrome experienced by astronauts spending time on the space station.
Infantile hydrocephalus and benign external hydrocephalus and the role of the latter as a potential cause of NPH later in life are discussed, in addition to examining changes in DTI and MR elastography in NPH and discuss related topics such as aqueductal stenosis and pseudotumor cerebri.
