Mamourian T.J. Vaccaro A.-C. Duhaime SUMMARY: The programmable CSF shunt valve has become an important tool in hydrocephalus treat- The 2010 AJNR article by Lollis et al. 1 provides radiographic features (with reference images) of the settings of five common valves (Codman Hakim Programmable Valve, Medtronic Strata, Sophysa Sophy SM8, Sophysa Polaris SPV, and Aesculap Miethke proGAV). It is important to acquire zoomed in radiographs of the valve en face, to best assess the The shunt series is a set of radiographic images performed to assess the location and integrity of a ventriculoperitoneal shunt. Indications Departmental protocols will vary but the overall goal is to image the shunt in its entirety to assess However, programmable shunt valves are adjusted with an external magnet. Changes in the valve-pressure setting have occurred after exposure of programmable valves to an MRI magnetic field [ 21 ]. Before performing MRI on a patient with a programmable shunt, the radiologist must confirm that the shunt is resistant to reprogramming at the The setting of the valve can be determined by comparing the position of the radiopaque marker on the valve cam to the fixed position of the radiopaque right-hand side indicator on the base plate of the valve.

Background A new adjustable valve, the Codman CertasTM valve for treatment of hydrocephalus was introduced into clinical practice in January 2011. It has 8 different settings with an opening pressure varying from 36 to over 400 mm H2O at a flow rate of 20 mL/h. The 8th setting is designed to provide a "virtual off" function. The objective of this report is to describe the initial clinical
