Abstract

Highlights: PC cine MRI can measure the CSF flow dynamics in the tube of VP shunt. The method by using PC cine MRI is non-invasive and convenient to evaluate shunt malfunction. The method to measure CSF velocity by PC cine MRI is feasible to improve the diagnosis VP shunt malfunction. Abstract: The ventriculoperitoneal (VP) shunt is a gold standard procedure to treat hydrocephalus. However, shunt malfunction is the common complications after surgery. In this study, we utilize phase-contrast cine magnetic resonance imaging (PC cine MRI) to improve the diagnosis of VP shunt malfunction. In in vitro and in vivo experiment results demonstrate the cerebrospinal fluid (CSF) flow velocities in the shunt tube are significantly decreased in the shunt malfunction group, which indicated PC cine MRI could evaluate the CSF flow dynamics of VP shunt effectively. This method is noninvasive and simple, also can improve the diagnosis of shunt malfunction.
