We compared the artifact induced by the Certas Plus at 3.0T vs 1.5T in 9 patients with idiopathic normal pressure hydrocephalus (iNPH) on six sequences (3D MPRAGE, Sagittal T1, axial DWI, axial GRE, axial T2 FLAIR, axial T2 FSE) at three levels (atria of the lateral ventricles, cerebral aqueduct, and cerebellum hemispheres). The 1.5T scans had a significantly greater area of artifact on DWI (all levels) and GRE (cerebellar level) sequences, and a smaller area of artifact on T2 FLAIR (cerebellar level). Post-shunt imaging at 3T with the Certas plus valve is feasible and with lesser artifact than on 1.5T.
