Summary
Our research aims to reveal whether the low b-values distribution and the number of NEX for each b value will influence the accuracy of pseudodiffusion parameter derived from IVIM in brain.
Detailed description
As an improved MRI technique, diffusion-weighted imaging (DWI) is considered the most sensitive for early pathological changes. Perfusion measurement has been shown to improve sensitivity and predictive value for tumor grading and prognosis, also as a predicator of recovery with reperfusion in patients of acute ischemic stroke.Our research aims to reveal whether the low b-values distribution and the number of NEX for each b value will influence the accuracy of pseudodiffusion parameter derived from IVIM in brain.
