He aha ka ke kiʻi o ka MRI? I MRI diagnoses?

ʻike, a maʻi nui nunui huikau ma ka mea ana i mea e pololei hooholo i ka pilikia, e nānā i nā hiʻona o mawaho'aʻaʻa loli, loli i loko o kona 'ole. Ma na hihia a pau, me ka maikai ano no kaʻike, meaʻume mākenēki resonance kiʻi (MRI).

He aha kaʻume mākenēki resonance kiʻi

Visualization ma MRI keia ka loa, he pono ole, no ka mea, e leie aku oe e visualize kokoke a pau na na nā loko, a huai ae mall loli i nā'aʻaʻa a me nā loko; Ma kekahi, pona kiʻi o ka lolo MRI ka loa informative a loa kōkua maikaʻi i loko o kaʻike, o intracranial hikoko o Ka maʻi 'aʻai, hahauʻana (manawa pakahi aku la ia waiwai, e ike i ke kikowaena ma ka hemorrhagic mapuna hoe) a me ka vascular maʻi (aneurysms paha malformations); MRI mea pono, a me ka loa traumatic lolo eha.

pono o ka iaoiaeii

MRI hiehie i kaʻike pono a me ka exhibition, akā, i ka mea ia manawa a me ka maluhia no ka hoʻomanawanui.

Na C. Brewer a lanakila o MRI mea i ka mea, ua ike i hiki ke loaa ia piha piha nā kiʻi o na nā loko a me nā'aʻaʻa me ka hoʻohana 'ana o ka Akä naÿe no nä konohiki.

Naʻe, i loko o kekahi mau hoopii, no ka oi piha visualization o ka Akä holomua mea hoʻohana; i ka nui, ka mea, Ua pili ka wā o nā ao o ka cerebral vascular pathology. Pictures o ka lolo MRI me ka Akä ka loa informative ma huʻi cerebral circulatory kāna hana, no ka mea, e ka mea hiki ke kumumea i ke kiʻekiʻe o ka moku ino, a me ka kiko'ī Ana o ka pathological pulakaumaka.

Pehea e holo ai ka mīkiniʻimi

Ma lalo o ka aoao o ka meaʻume mākenēki oscillations hoʻololi hana o ka hydrogen nā'ātoma, mai ua loli ke noi ano ikaika kauoha (particles) i loko o ka nucleus o ka hydrogen'Ātoma. Ma ka hoopau ana o ka neʻeʻana ikehu ua kinoea, paa lima kūlana kiʻekiʻe.

MRI PalekanaEND_LINKʻano hana i na hana e ka nānā 'ana ma luna o ʻume mākenēkiʻike manaʻo o ka resonance. I ka rula o ka hana ana o PalekanaEND_LINK lako a pan a me ka mea i loko o ka loli o ka Radio lepa i loko o ke kiʻi. A Radio neaiae i loaa mai transformsʻume mākenēki resonance spectrometer.

Aie i ka waiwai o ka hydrogen nā'ātoma, ka maʻiʻo o ka i loko o ke kanaka kino kīnā umi pakeneka o kaʻike, Ua hiki ole i ka iki pōʻino ke ola.

Kela manawa, hoomakaukau kiʻi, kauka hoʻomalu o ka like holoʻokoʻa o ka kūpono kiʻi ua ua kālailai, like me ka kūmau, a huai ae pathological loli.

kiʻina hana a ka Mōʻaukala

Ke kŰia o nukeleaʻume mākenēki resonance i ike a i ho'ākāka 'ia aku i loko o ka waena o ka iwakalua kenekulia - i ka 1946. A no ka manawa mua loa i loaa i ke kiʻi me ka kōkua o kēia 'enehana mea, pomaikai ae la lakou i ka 1973.

Pehea o ke anamanaʻo

Externally, i ka nakeke no kaʻume mākenēki resonance kiʻi nana e like loa me ka lōʻihi ololi Tube.

I ka waiho i loko o ka hoʻomanawanui study hale mai ka hoʻohana 'ana i ka kūikawā wahi moe.

Mai ka lōʻihi like 'ole o ka noho ana o ka hoʻomanawanui i loko o ka mokuna mea nō kiʻekiʻe - mai i hookahi kanaha minuke, a ma kekahi mau loa hihia - e oi aku ana no ka noho ana o ka hoʻomanawanui i loko o ka "Tube" E e like' oluʻolu me hiki. Loko o ka mea ua kākoʻo 'ia e blurred malamalama a me ka hoʻokomo ea, lawa e hōʻoia i ka noho malie hanu. He OAXA i loko o ka mokuna pono e kamaʻilio me ke pihi Aʻole e mālama nei i ka manaʻo.

ʻike, o ka lolo pathology

I ka wa e hele mai i ka PalekanaEND_LINK ninaninau ana i ka loloʻume mākenēki resonance kiʻi (MRI) o ka loa informative ninaninau o ka nānaina.

I ka mea, MRI scan NineManga.com o ka lolo - he Hawaii photo o kona papa.

No laila, mahalo i kēia PalekanaEND_LINK iaoia i hiki, loa piha study o ka lolo waiwai, a me ka 'ike o abnormalities ma ka wā kahua o ka hoʻonaʻauao.

MRI lolo scan NineManga.com e e hanaʻia i loko o ka kēia hihia.

1. Huʻi ischemic hahau ana.
2. Loa traumatic lolo eha. I ka wā o ka traumatic lolo 'eha i mea e pale fracture o ka puniu wale iwi ua maliuia mai e hana i ka X-Ray o ke poo. MRI, aka, e leie aku e visualize ole wale o ka puniu wale no, aka, i ka moku'āina o intracranial hale.
3. Na hoailona o intracranial hypertension. Ma keia kulana, i ka 'ike o ka koe a intracranial ka leo nunui kōkua i ke kahua o kekahi papa kiʻi. MRI o ka lolo ma hypertensive maʻi pale hookohu e hōʻoia diagnoses e like me intracranial hematoma, intracranial ʻeho, lolo abscess.
4. Anomalies o cerebral moku.

6. MRI kōkua piha kiʻi, a hoonoho iho la i ka wahi, a (ma ka hou hookolokolo) i nāʻano o nā neuromas a me cystic me ka ho okumu.

ʻike, o spinal pathology

ʻume mākenēki resonance kiʻi o ke alanui nui e diagnose pathological rula o ka spine.

I ka hopena, e ia i ka piha PalekanaEND_LINK hana stratified kiʻi.

MRI o ka thoracic spine ua häʻawi mai ai iä ia kēia nāʻikepili:

• Pain maʻi pale o ka ike etiology i loko o ka pahu āpana - e pale ho okumu ana o iniiaiie Ka maʻi 'aʻai a metastatic lesion.
• Neurological symptoms, hiki i ke alo o intervertebral hernia.
• Ke kaʻina hana i pili pu laua imua oʻoki kino, a ma hope o ka mea - i ka pāʻana i nāʻano o ke ola keʻano o ka hanaʻana.
• Eha me ka manao fracture o ka pahu - i mea e pale aku iwi pōʻino. No ka mea, tomography hoʻolako i ka piha layering i ke kiʻi, ka mea i oi kōkua maikaʻi i loko o kēia mau wahi, i hiki ma mua o ka X-Ray.

MRI o ka lumbar mai PalekanaEND_LINK cia ma ka kēia hihia.

• Hoopii o kaʻeha i loko o ka lumbosacral'āina, i ka nele o ka laulā o ka X-Ray haʻawina.
• Ma hope o nā palapū i kēia wahi - i mea e pale aku iwi a me ka traumatic nā palapū.
• Ka wā diagnosed fractures o ka spine, huikau ma pohupani hale o ka iwi mamala - e möakäka hou i ka nui o ka pohupani hale, pale poino o intervertebral cartilage, meninges a me spinal kaula.
• No ka palena pauʻike, o degenerative loli o ka spine a me ka vertebrae like me ka hopena o ka make ana o metastatic lesions.
• Neurological symptoms e hoike ana ae hookaawale ole mīkini'opihia o ke aʻalolo kumu mīkini'opihia ke kumu no ia e hoakaka ia; ma keia hihia, no kaʻike, o vertebral pohupani hale, a me ka mea nui e e ka X-Ray. MRI o ka spine pono, e lawe mai i ka hōʻike pathology o nerentgenokontrastnyh'aʻaʻa (ka pohupani hale o ka intervertebral iwi kuamoʻo, herniated iwi kuamoʻo, hoʻoʻino edema, compressing ka mīkini'opihia nā aʻalolo kumuʻeho ma o na la).
