RESULTS: Almost all shunt valves were immune to reprogramming by the iPad 3 at varying distances (including direct contact) except for the Strata II small valve, where rotating the peak flux location 4 mm above the valve changed the valve pressure settings every time.

The pressure setting can be read on the radiograph, but not on the axial CT image (b).
For further informa Medtronic (PS Medical) Strata Valve Strata valves and their flow-regulation adjustment can be identified in plain skull X-rays. MRI scanners up to 3 Tesla are quoted to be safe, but a post-MRI radiologic check of adjustment is recommended in literature. Almost all shunt valves were immune to reprogramming by the iPad 3 at varying distances (including direct contact) except for the Strata II small valve, where rotating the peak flux location 4 mm above the valve changed the valve pressure settings every time. The Strata NSC LP shunt is designed to provide continued cerebrospinal fluid flow from the lumbar subarachnoid space into the peritoneal cavity. The Strata NSC lumboperitoneal valve allows the physician to noninvasively adjust the pressure/flow performance level settings pre- and post-implantation to address changing patient needs. The CERTAS Plus Programmable Valve allows a surgeon to non-invasively change the opening pressure to one of eight performance settings, which range from 1 (low pressure) to 7 (high pressure), plus performance setting 8, which is a "Virtual Off." This programmability may negate the need for revision surgery to alter the valve pressure.
Changes the valve’s performance setting. It provides an audible click and tactile response as you turn to each setting. It also features a safety stop between settings 1 and 8. Please refer to the instructions for use (in pocket of carrying case) for step-by-step instructions of pre- and post-implantation procedures for indicating

shunt.
The Strata valve has 5 settings or P/L, ranging from 0.5 to 2.5 . Each performance level corresponds to a range of opening pressures and flow rates; generally, a lower performance level corresponds to a lower opening pressure. In summary, the optimal setting for the treatment of a patient with iNPH is a VP shunt with an opening pressure of 5 cm H 2 O and a gravitational unit (shunt assistant, proSA), which will prevent overdrainage, at 20 cm H 2 O. Adjustability is beneficial for the patient, and the first adjustments should be performed at about 3 months after surgery.

The valve applied in the study was the Strata® (Medtronic), which is an externally adjustable magnet-ic radiopaque with anti-siphoning valve programmed to one of five performance level settings, from 0.5 to 2.5, with The following valves were evaluated: Codman Hakim programmable valve, Medtronic Strata II valve, and Aesculap proGAV. Each valve was tested at distances of 0 to 50 mm (in 5-mm increments) from each headphone. The exposure time at each distance was 1 minute, and 3 trials were performed to confirm results at each valve setting and distance. 2020-06-24 Each performance level setting on the STRATA valve corresponds to a final pressure reading as shown in the legend. Flow rate depends on shunt valve pressure setting.
The setting levels range from 0.5 to 2.5 • You will be provided a card noting your child’s valve setting, please keep this card available at all times. • The strata valve is “MRI safe.”

Medtronic strata II programmable valve in situ. Pre-MRI setting is P/L 2.5. It is essential that when reporting these valves the manufactures guide to confirming that model of the valve and assessing the setting of the valve are consulted. The following valves were evaluated: Codman Hakim programmable valve, Medtronic Strata II valve, and Aesculap proGAV. Each valve was tested at distances of 0 to 50 mm (in 5-mm increments) from each headphone. The exposure time at each distance was 1 minute, and 3 trials were performed to confirm results at each valve setting and distance.
