Purpose To investigate the variation in the quantification of the carotid degree of stenosis (DoS) with a dual energy computed tomography (CT), using different energy levels during the image reconstruction. Methods In this retrospective study, 53 subjects (37 males; mean age 67 ± 11 years; age range 47–83 years) studied with a multi-energy CT scanner were included. Datasets were reconstructed on...
Purpose In patients with ICA stenosis, increased peak systolic velocity is a marker of stenosis at risk of ischemic stroke. 4DFlow MRI is a reproducible technique to evaluate velocities in ICA stenosis, although it seems to underestimate velocities as compared with Doppler ultrasonography. The purpose of our study was to confirm that velocities were underestimated on a new set of data acquired with...
