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...

Imaging tumour cell proliferation, death and necrosis Diffusion weighted-MRI exploits intrinsic contrast arising from the thermal displacement of water molecules over a given time. In biologic tissues, the movement of water molecules is hindered because their motion is limited by interactions with cell ...
MRI measurements of the knee were acquired in the sagittal, coronal, and axial planes. The sagittal plane included the T1-weighted and T2-weighted phases. All images were reviewed by 2 senior orthopedic surgery residents. All measurement collections were performed by two trained orthopedic surgeons ...
