When compared with conventional TOF, the sparse TOF which applied compressed sensing to accelerate the acquisition time has been proved to be well-performed in evaluation of UIAs. However, the image quality and the agreement between sparse TOF and DSA need to be studied further. We therefore assessed the clinical validation of sparse TOF compared with conventional TOF in qualitative and quantitative image qualities and explored the correlation among two MRAs and DSA in evaluation of size parameters.
