Recent studies have shown that cerebrospinal fluid (CSF) flow is strongly affected by respiration, which may potentially be used for future diagnosis and treatment follow-up in diseases such as normal pressure hydrocephalus and congenital malformations. However, quantitative measurements of respiratory effects on CSF flow in small diameters are not currently available. Therefore, this abstract shows a phantom validation of flow measurement using a radial golden-angle real-time flow sequence, reconstructed using compressed sensing. Results show that mean velocities can be quantified with a small underestimation, suggesting that the protocol is promising for future study of respiratory effects on CSF flow.
