Intraspinal compliance is related to neurological diseases and can be measured by pulse wave velocity (PWV). A multiband CINE phase-contrast MRI sequence was developed to measure the intraspinal PWV between two simultaneously acquired slices along spine. The method was evaluated in-vitro, in healthy-subjects and in a normal pressure hydrocephalus patient. In-vitro results show good reproducibility and dependency on transmural pressure in agreement with theory. A higher PWV compared to healthy subjects is observed in the patient. A decline in PWV after shunt surgery is detected, making it a promising tool for investigation and treatment follow-up of neurological diseases.
