The signal intensity in MRI depends on the proton density, T1, T2 and T2 relaxation processes of any ensemble of the spins within each imaging elements (voxel). Another important contrast mechanism in MRI is signal loss caused by proton dephasing in the presence of coherent and incoherent flow...
The body composition of all subjects was measured by using whole-body MRI. Protocols were described in more detail elsewhere (31, 32). Organs and tissues were obtained by using a 1.5-T Magnetom Avanto Vision Scanner (Siemens Medical Systems) with a T1-weighted-gradient echo sequence (repetition...

(DWI) lesion, cerebellar ICH, cerebellar microbleed, and cerebellar superficial siderosis (SS) (Fig.1). We also highlight the MRI techniques including susceptibility-weighted image (SWI) and 3D double-inversion recovery (DIR) which may improve the diagnostic performance and contribute to a better...

However, the mean pallidal index (PI) in anemic patients was similar to that of controls, and neither group had high signal intensity of the globus pallidus in T1-weighted MRI. This finding is in contrast to those of my previous study of males with liver cirrhosis. In this cirrhosis study...
Magnetization of static tissue, although slightly T2-weighted, is restored by a final tip-up pulse. Subsequently, a 3D TFE/TSE readout can be applied Full size image 3D black-blood MRI Increasing interest in isotropic 3D imaging protocols has led to the development of 3D black-blood imaging ...
