MRI contrast from relaxation along a fictitious field (RAFF).
A new method to measure rotating frame relaxation and to create contrast for MRI is introduced. The technique exploits relaxation along a fictitious field (RAFF) generated by amplitude- and frequency-modulated irradiation in a subadiabatic condition. Here, RAFF is demonstrated using a radiofrequency pulse based on sine and cosine amplitude and frequency modulations of equal amplitudes, which gi...
متن کاملRelaxation Along a Fictitious Field (RAFF) and Z-spectroscopy using Alternating-Phase Irradiation (ZAPI) in Permanent Focal Cerebral Ischemia in Rat
Cerebral ischemia alters the molecular dynamics and content of water in brain tissue, which is reflected in NMR relaxation, diffusion and magnetization transfer (MT) parameters. In this study, the behavior of two new MRI contrasts, Relaxation Along a Fictitious Field (RAFF) and Z-spectroscopy using Alternating-Phase Irradiation (ZAPI), were quantified together with conventional relaxation param...
متن کاملMesenchymal stem cells can survive on the extracellular matrix-derived decellularized bovine articular cartilage scaffold
Objective (s): The scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. The objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (...
متن کاملInvestigating Parkinson’s disease using rotating frame MRI
Introduction In our previous study performed at 4T on individuals with Parkinson’s Disease (PD) and age-matched controls we have demonstrated that rotating frame relaxation methods employing so-called adiabatic HS1 pulses are capable to separate PD from control subjects based on the values of adiabatic relaxation times in the substantia nigra (SN) [1]. With the goal of investigating the physiol...
متن کاملContrast Enhanced Imaging of Cartilage Reflects Changes in Both Water and GAG Content
INTRODUCTION: Contrast enhanced imaging of articular cartilage is predicated on the use of anionic contrast agents that function as mobile ionic probes that partition themselves in inverse proportion to the glycosaminoglycan (GAG) content of the cartilage matrix. GdDTPA (charge -2, 548 g/mol) has been used for delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) and Iox...
