Neurological PET/CT examinations are often performed with electroencephalogram (EEG) monitoring for epilepsy patients. However, the EEG electrodes cause metal artifacts in the reconstructed CT images which might propagate through the attenuation map into the PET reconstructions. In this study, the impact of the electrodes on the visual quality and quantification of brain PET images was investigated...
To demonstrate the discrepancy of cerebral blood flow volume (BFV) estimation with 2D phase-contrast (2D PC) MRA guided with 3D time-of-flight (3D TOF) MR localization by using an "internal" standard. 20 groups of the common (CCA), internal (ICA), and external (ECA) carotid arteries in 10 healthy subjects were examined with 2D PC MRA guided by 3D TOF MR angiograms. The sum BFV of the internal...
