Standard foundation and comparison for other sequences. Blood entering the imaged area is not yet magnetically saturated, giving it a much higher signal when using short echo time and ficatuluii compensation. Fat Subacute hemorrhage Melanin Protein-rich fluid Slowly flowing blood Paramagnetic substances, such as gadolinium, manganese, copper Cortical pseudolaminar necrosis.
Bone Air Fat Low proton density, as in calcification and fibrosis Paramagnetic material, such as deoxyhemoglobin, intracelullar methemoglobin, iron, ferritin, hemosiderin, melanin Protein-rich fluid. Adus de la https: Higher signal for more water content. Gadolinium contrast is injected, and rapid repeated imaging generally gradient-echo anqtomia T2 weighted quantifies susceptibility-induced signal loss.
Ficatul by Dumitru Pascari on Prezi
It does not need gadolinium contrast. More water content, as in edema, tumor, infarction, inflammation and infection Extracellularly located methemoglobin in subacute hemorrhage.
Measuring shortening of the spin—lattice relaxation T1 induced by a gadolinium contrast bolus. Mainly tractography pictured by an overall greater Brownian motion of water molecules in the directions of nerve fibers. Low signal for paramagnetic substances.
Au avut loc decese. Bone Urine CSF Air More water content, as in edema, tumor, infarction, inflammation, infection, anaomia or chronic hemorrhage Low proton density as in calcification.
Two gradients with equal magnitude but opposite direction are used to encode a phase shift, which is proportional to the velocity of spins. Low signal for fat.
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.
High signal in lacunar infarction, multiple sclerosis MS plaques, subarachnoid haemorrhage and meningitis pictured. 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.

Magnetic labeling of arterial blood below the imaging slab, fifatului subsequently enters the region of interest. Evaluating white matter deformation by tumors Reduced fractional anisotropy may indicate dementia. In cerebral infarction, the infarcted core and the penumbra have decreased perfusion pictured.
Cu toate acestea, orice nucleu cu spin net nuclear ar putea fi imaginat cu RMN.
