Cu toate acestea, orice nucleu cu spin net nuclear ar putea fi imaginat cu RMN. Au avut loc decese. Adus de la https: Fat Subacute hemorrhage Melanin Protein-rich fluid Slowly flowing blood Paramagnetic substances, such as gadolinium, manganese, copper Cortical pseudolaminar necrosis. More water content, as in edema, tumor, infarction, inflammation and infection Ticatului located methemoglobin in subacute hemorrhage.

Bone Urine CSF Air More water content, as in edema, tumor, infarction, inflammation, infection, hyperacute or chronic hemorrhage Low proton density as in calcification.

Bone Air Fat Low proton density, as in calcification and fibrosis Paramagnetic material, such as ifcatului, intracelullar methemoglobin, iron, ferritin, hemosiderin, melanin Protein-rich fluid.

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. Higher signal for more water content.

Low signal for fat. Low signal for paramagnetic substances.

Standard foundation and comparison for other sequences. 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.

Evaluating white matter deformation by tumors Reduced fractional anisotropy may indicate dementia. Gadolinium contrast is injected, and rapid repeated imaging generally gradient-echo echo-planar T2 weighted quantifies susceptibility-induced signal loss.

Imagistică prin rezonanță magnetică

In cerebral infarction, the infarcted core and the penumbra have decreased perfusion pictured. Measuring shortening of the spin—lattice relaxation T1 induced by a gadolinium contrast bolus.

Magnetic labeling of arterial blood below the imaging slab, which subsequently enters the region of interest. It does not need gadolinium contrast. Blood entering the imaged area is not yet magnetically saturated, giving it a much higher signal when using short echo time and flow compensation.

Two gradients with equal magnitude but opposite direction are used to encode a phase shift, which is proportional to the velocity of spins. Sensitive for blood and calcium, by a fully flow compensated, long echo, gradient recalled echo GRE pulse sequence to exploit magnetic susceptibility differences between tissues.
