Sensitive for blood and calcium, by a fully flow compensated, long echo, gradient recalled echo GRE pulse sequence to ficatilui magnetic susceptibility differences between tissues.
Bone Urine CSF Air More water content, as in edema, tumor, infarction, inflammation, infection, hyperacute or chronic hemorrhage Low proton density as in calcification.

Low signal for paramagnetic substances. Standard foundation and comparison for other sequences.
Gadolinium contrast is injected, and rapid repeated imaging generally gradient-echo echo-planar T2 weighted quantifies susceptibility-induced signal loss. Measuring shortening of the spin—lattice relaxation T1 induced by a gadolinium contrast bolus.
Low signal for fat. High signal in lacunar infarction, multiple sclerosis MS plaques, subarachnoid haemorrhage and meningitis pictured.

Mainly tractography pictured by an overall greater Brownian motion of water molecules in the directions of nerve fibers. Magnetic labeling of arterial blood below the imaging slab, which subsequently enters the region of interest.
Evaluating white matter deformation by tumors Reduced fractional anisotropy may indicate dementia. Two gradients with equal magnitude but opposite direction are used to encode a phase shift, which is proportional to the velocity of spins.
More water content, as in edema, tumor, infarction, inflammation and infection Extracellularly located methemoglobin in subacute hemorrhage. Cu toate acestea, orice nucleu cu spin net nuclear ar putea fi imaginat cu RMN. Au avut loc decese.
Higher signal for more water content. Adus de ficatylui https: Lower signal for more water content, as in edema, tumor, infarction, inflammation, infection, hyperacute or chronic hemorrhage High signal for fat High signal for paramagnetic substances, such as MRI contrast agents Standard foundation and comparison for other sequences.
It does not need gadolinium contrast.
Fat Subacute hemorrhage Melanin Protein-rich fluid Slowly flowing blood Paramagnetic substances, such as gadolinium, manganese, copper Cortical pseudolaminar necrosis. Fjcatului Air Fat Low proton density, as in calcification and fibrosis Paramagnetic material, such as deoxyhemoglobin, intracelullar methemoglobin, iron, ferritin, hemosiderin, melanin Protein-rich fluid.
In cerebral fixatului, the infarcted core and the penumbra have decreased perfusion pictured. Blood entering the imaged area is not yet magnetically saturated, giving it a much higher signal when using short echo time and flow compensation.
