Theoretical derivation of blood velocity from TOF-MRA based artery centerline
Abrar Faiyaz
Time-of-flight magnetic resonance angiography (TOF-MRA) is widely used for nonin-vasive visualization of arterial anatomy, but extracting hemodynamics like blood velocity typically…
ArteryX: A Reliable End-to-End Toolbox for Standardized Intracranial Artery Feature Extraction from 3D TOF-MRA
Abrar Faiyaz, Nhat Hoang, Giovanni Schifitto +1
Cerebrovascular research heavily relies on quantitative analysis of intracranial arteries from time-of-flight magnetic resonance angiography, yet existing processing pipelines rema…
Angular upsampling in diffusion MRI using contextual HemiHex sub-sampling in q-space
Abrar Faiyaz, Md Nasir Uddin, Giovanni Schifitto
Artificial Intelligence (Deep Learning(DL)/ Machine Learning(ML)) techniques are widely being used to address and overcome all kinds of ill-posed problems in medical imaging which…
Single-Shell NODDI Using Dictionary Learner Estimated Isotropic Volume Fraction
Abrar Faiyaz, Marvin Doyley, Giovanni Schifitto +2
Neurite orientation dispersion and density imaging (NODDI) enables the assessment of intracellular, extracellular and free water signals from multi-shell diffusion MRI data. It is…
