First, analyses of signal changes in occluded venous sinuses segments (defined by and unblinded to CEMRV) on native 3D-TOF images and morphological MRI sequences were performed. Second, a blinded (to CEMRV and other morphological MRI sequences) analysis was performed on 3D-TOF imaging ...
Conclusions: In addition to the degree of stenosis, the vulnerability and morphology of plaques on HR-MRI may influence signals on 3D-TOF-MRA. The presence of signal loss on 3D-TOF-MRA is associated with recent ischemic stroke.Quantitative Imaging in Medicine and SurgeryTianwei WangCaixia Li...

The paper describes a universal program MRIA for the full profile analysis of powder neutron-diffraction time-of-flight direct and Fourier spectra. The minimum configuration of MRIA, analysing up to four spectra, four phases, 500 Miller indices for every phase and 100 independent atoms, can run...
Fig. 2: Correction of sample motion enables field-based diffuse optics. a Geometry for human forearm measurement, where αSD (source–detector angle) is ~10°. For a 2 ms segment at the peak time-of-flight (solid black vertical line in b), the autocorrelation (c) rotates with lag time...
Imaging follow-up at 3T of intracranial aneurysms treated with the WEB Device has not been evaluated yet. Our aim was to assess the diagnostic accuracy of 3D-time-of-flight MRA and contrast-enhanced MRA at 3T against DSA, as the criterion standard, for the follow-up of aneurysms treated wi...
The different companies in the domain of medical imaging have now all introduced time-of-flight technology in their whole body PET/CT and some in their PET/magnetic resonance imaging (MRI) systems. The Philips Gemini TF scanner [11] was the first clinical TOF-PET/CT scanner and has been in...
