Does non-invasive computational fluid dynamics accurately estimate fractional pressure ratio compared to invasive measurement in patients with severe intracranial stenosis?
A non-invasive computational fluid dynamics method based on CT angiography can accurately estimate the fractional pressure ratio in severe intracranial stenosis, comparable to invasive measurements.
Liu et al. (2016) conducted an observational in Severe intracranial stenosis (n=11). Computational fluid dynamics-based method (FPR CFD) vs. Invasive fractional pressure ratio measurement was evaluated on Fractional pressure ratio. A non-invasive computational fluid dynamics method achieved comparable results to invasive measurements for assessing fractional pressure ratio in 11 patients with severe intracranial stenosis.
