Astrocytic tumour grading: a comparative study of three-dimensional pseudocontinuous arterial spin labelling dynamic susceptibility contrast-enhanced perfusion-weighted imaging and diffusion-weighted imaging

摘要

ObjectivesWe hypothesized that three-dimensional pseudocontinuous arterial spin labelling (pCASL) may have similar efficacy in astrocytic tumour grading as dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC-PWI), and the grading accuracy may be further improved when combined with apparent diffusion coefficient (ADC) values.
