Adjustable valve–induced artifacts can conceal brain pathology on MR images. This should influence the choice of valve implantation site and the type of valve used. The effect of artifacts on DW images should be highlighted pending the development of less MR imaging artifact–inducing adjustable shunt valves. 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), functional alterations, and artifacts at 3T. The programmable valve showed minor magnetic field interactions and heating was not excessive (+0.8 degrees C). The function of the programmable valve was not the shunt valve had migrated into diploe of parietal bone. Further, shunt series X-rays (Fig.

A magnetically programmable CSF shunt valve (Codman Certas Programmable Valve, Codman, a Johnson & Johnson Company), which is in regulatory review, was evaluated in a 3-T MRI environment ().This device is used to regulate intraventricular pressure by means of a ball-and-cone mechanism under the control of a calibrated flat spring and can be noninvasively … According to the AJNR 2010 article by Lollis et al, the Codman Hakim valve is set at 60 mm water (which is the same as the pre MRI setting). Case Discussion This is an example of a Codman Hakim valve. The CODMAN HAKIM Programmable Valve (CSF shunt valve, Codman, a Johnson & Johnson Company, Raynham, MA) includes a valve mechanism that incorporates a flat 316L stainless steel spring in which the calibration is accomplished by a combination between a pillar and a … 2010-07-01 The programmable CSF shunt valve has become an important tool in hydrocephalus treatment, particularly in the NPH population and in pediatric patients with complex hydrocephalus. The Codman Hakim valve is a ventricular shunt valve which can be programmed to open at various CSF fluid pressure. As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter.

As the name suggests, a catheter is placed with its tip in the ventricle. The external portion of the catheter is connected to a valve that regulates the flow of CSF based on a preset pressure. In consideration of the test results, this new programmable CSF shunt valve is not adversely affected by the 3-T MRI environment and is acceptable for a patient undergoing MRI at 3 T or less when specific guidelines are followed, including verifying the valve setting according to manufacturer recommendations immediately after the MRI procedure. 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.
