Magnetic resonance imaging artifacts caused by aneurysm clips and shunt valves: dependence on field strength (1.5 and 3 T) and imaging parameters. J Olsrud

Newer valves such as the Polaris (Sophysa) and Pro-GAV (Aesculap) are resistant to reprogramming even at a 3-T magnetic field. If an unfamiliar valve is encountered, the radiologist should contact the manufacturer for specific … This video covers the 3 types of Medtronic valves used for the treatment of hydrocephalus: the Contoured Valve, part of the CSF Flow Control valve family; th The last half-century has seen significant advancement in the management of hydrocephalus. In 1955, John Holter, an American engineer, invented the first cerebrospinal fluid (CSF) shunt valve for implantation into his son who had been born with hydrocephalus. Initially, all shunt valves had fixed opening pressures. According to the 2010 AJNR article by Lollis et al, the shunt is in keeping with a Sophysa Polaris SPV shunt with the valve set to position 3 which corresponds to an opening pressure of 110 mm H20. Case Discussion. This is an example of a Sophysa Polaris SPV programmable VP shunt valve.

Usually, a simple lateral skull X-ray helps to identify the type of valve and it’s adjustment. A programmable CSF shunt valve was assessed for magnetic field interactions, heating (transmit-receive body radio-frequency coil; whole-body averaged specific absorption rate, 2.1 W/kg SUMMARY: The programmable CSF shunt valve has become an important tool in hydrocephalus treat-ment, particularly in the NPH population and in pediatric patients with complex hydrocephalus. The purpose of this study is to provide a single reference for the identification of programmable shunt valves and the interpretation of programmable shunt valve settings.
