Waa maxay sawirka MRI ah? In cudurka MRI?

Garashada cuduro badan oo la taaban karo adag by xaqiiqada ah in si si sax ah loo ogaado dhibaatada, arki sifooyinka of isbedel unug dibadda, isbeddel ah ee qaab-dhismeedkooda. Xaaladaha noocaas ah, habka ugu fiican ee cudurka waa resonance magnetic imaging (MRI).

Waa maxay magnetic resonance imaging

Muuqaalaynta by MRI maanta waa mid caadi ah maxaa yeelay waxa ay kuu ogolaanaya in aad arki dhowaad dhammaan xubnaha gudaha iyo ogaado isbedel dhismaha ee unugyada iyo xubnaha; Gaar ahaan, sawirada israac ee MRI maskaxda waa mid aad wargelin ah iyo mid wax tar leh in cudurka of burooyinka intracranial kansarka, stroke (fursad gaar ahaan qiimo leh in la arko xarunta in stroke dhiigbaxa) iyo cudurka dhuumaha (aneurysms ama curyaanimo); MRI waa lagama maarmaan, iyo in dhaawac daran maskaxda.

Faa'iidooyinka habka

MRI isku daraa ee aragti iyo bandhig, laakiin waqti isku mid ah iyo badbaadada bukaanka.

Faa'iidada la dafiri karin ee MRI waa in ay iska caddahay in sawiro faahfaahsan oo sida faahfaahsan ee xubnaha gudaha iyo unugyada waxaa laga heli karaa iyada oo aan isticmaalka wakiilada duwan.

Si kastaba ha ahaatee, mararka qaar, waayo, muuqaalaynta a faahfaahsan oo dheeraad ah ee horumarinta ka duwan yahay loo isticmaalo; gaar ahaan, waa lagu dabaqi karo marka daraasadda of cudurada vascular cerebral. Pictures of MRI maskaxda la barbardhigo uu yahay mid aad wargelin ah in xanuunada wareegga cerebral ba'an, tan iyo markii ay ka dhigi suurto gal si loo raad raaco heerka dhaawaca markabka iyo dhinacyada saxda ah ee diiradda bahal ah.

Sidee scanner ah

Under saameynta ay ku oscillations magnetic dhaqanka atamka hydrogen ku beddelo, tan iyo hab mooshin la bedelo si togan eedeeyay Qurub in xuduntii eb hydrogen ah. Ugu joojiyo oo tamarta dhaqdhaqaaqa la timaada, qalab go'an.

shuqullada farsamo ogaanshaha MRI ku salaysan ifafaale magnetic of resonance. Mabda'a hawlgalka qalabka ogaanshaha iyo waa in loo badalo mid ah calaamadaha radio sawirka. signal A radio ka helay badalaa spectrometer resonance magnetic.

Maadaama uu sifooyinka atamka hydrogen, content ee taas oo jidhka bini'aadamka gaadho toban boqolkiiba ogaanshaha sida suurto gal ah oo aan waxyeelo ugu yar caafimaadka.

Hore u qaadanaysay image diyaar, dhakhaatiir takhasus ah profile ee u dhiganta of image keentay waa la falanqeeyay, la iska caadi ah oo lagu ogaado isbedel bahal ah marka la barbar dhigo.

habka Taariikhda

Arrin ku resonance magnetic nuclear la helay iyo ku tilmaamay more dhexe ee qarnigii labaatanaad - 1946. Oo markii ugu horeysay si aad u hesho image ah iyadoo la kaashanayo of technology this waxaa ku guulaysteen in ay 1973.

Sidee waa sahanka

Dibadda, qalab loogu magnetic resonance imaging u eg ilaa xad tube dheer cidhiidhi ah.

Marka kaalinta gudaha xarun waxbarasho bukaanka isticmaalaya Gogol gaar ah.

Tan iyo muddada joogista ee bukaan-socodka ah ee unit uu yahay mid qaali ah - ilaa iyo afartan daqiiqo, iyo xaaladaha daran qaar ka mid ah - xataa xaaladaha dheeraad ah oo ku joogista ee bukaan-socodka ah ee "tube" waa in sida ugu raaxo badan ee suurtogalka ah. Inside qalabka waxaa lagu taageeray by iftiinka cawlan iyo hawo, oo ku filan si loo hubiyo neefta xasilloon. Waxaa waajib ah in unit waa in ay kula xidhiidhaan button operator waxaa waraysi daraasad ah.

tababarka

• nidaamka MRI waa in aan lagu sameeyo caloosha buuxda.
• Baaritaanka ka hor, sahanka bukaanka waa in meesha laga saaro waxyaabaha biraha oo dhan (soo jeedo, dahabka, biinka timaha, la gashado).

Inta nidaamka, bukaanku leeyahay inuu la jiifsado sida weli intii suurto gal ah sida image sahanka lagu sameeyey, iyo sida ay noqon doonto cad, ogaanshaha badan oo sax ah iyo doonista wanaagsan. Sidaa darteed, in kiisaska waxaa loo baahan yahay si ay u fuliyaan daraasad tomographic ilmaha yar isaga oo leh ee scanner ah iyo khabiiro lagu qasbay in ay meel hooyadiis.

natiijooyinka sahankani

scan MRI - taxane ah oo images, kuwaas oo images israac ee xubnaha gudaha.

Natiijada daraasaddan tomographic waa diyaar, caadi ahaan dhowr saacadood ka dib hawl ogaanshaha gudahood.

bukaanka uu helo ka soo gaartay sawir daabacan oo ah MRI ah, taas oo ka tarjumaysa aasaasiga ah, images muhiimka ah, iyo foomka ra'yi xirfadeed.

Wixii sahlanaato, xaalado badan, bukaanka waxaa la siiyaa gacanta sida la drive oo dhan, iyada oo aan marka laga reebo, images ka helay inta lagu guda jiro nidaamka. midka Tani waa mid aad u muhiim ah in kiisaska bukaanka waa mustaqbalka codsan doonaa kelmadaha xogta helay cudurka of xirfadlayaasha kale.

Tilmaamayaasha for imaging

Farsamada Tani waxay ka caawisaa si Heer sare ah ee sax loo arki xaaladda iyo qaab-dhismeedka:

• maskaxda iyo xangulada;
• dhabarta iyo kala-goysyada,
• cajaladood intervertebral;
• xabadka iyo caloosha,
• nidaamka wadnaha.

Waxa loo isticmaalaa cudurka isbedel bahal ah ee ka mid ah xubnaha iyo nidaamka.

muujinaya waxa kale oo jira xaalado marka cudurka of dhaawacyo ma aha macluumaad ku filan oo la siiyo by ee X-ray.

MRI waa lagama maarmaan xaaladaha marka uu jiro shaki ah cudurada dhismaha of unugyo ama xubno jidh.

peculiarity ee habkan uu ka kooban yahay in farsamadaan si weyn wax ku ool ah in daraasad unug jilicsan.

Aan baaray iyadoo la isticmaalayo imaging:

• nudaha lafaha.
• unugyada sambabada.
• Caloosha iyo dhammaan qaybaha xiidmaha.

Sababo iyo xadeynta

Habka of magnetic resonance imaging waa ammaan iyo da'da uu leeyahay sababo lahayn. Si kastaba ha ahaatee, tiro ka mid ah sababo weli ka jiraan:

• Marka la eego cayimayo ee nidaamka this lagu ogaanayo, waxaa waa u dadka bukaanka ah isagoo jidh kasta inclusions macdan ah, tusaale ahaan, implants (tus in saabka cranial) iyo m. P.
• Waxaa sidoo kale ahaan uu for MRI waa joogitaanka bukaan pacemaker ah.
• Iyada oo daryeel weyn waa in la qiimeeyo bukaannada qaba lugood, sida lugood oo wadajir ah

• stage wadnaha oo shaqadiisa gaba decompensated.
• Joogitaanka lugood vascular ama khaanadaha wadnaha.
• Joogitaanka tattoos la pigments biraha.

Garashada cudurada maskaxda

Marka ay timaado in baaritaan lagu ogaanayo ee imaging maskaxda resonance magnetic ah (MRI) waa baaritaan ugu wargelin of view.

Dhab ahaantii, baaritaano MRI ee maskaxda - sawirka layers ay.

Sidaa darteed, si ay u mahad habkan ogaanshaha noqdo suurto gal ah, daraasad ugu faahfaahsan oo ah walaxda maskaxda iyo aqoonsiga ee aan caadi ahayn ee marxaladaha ugu horreeya.

maskaxda MRI baaritaanku in la sameeyo arrimaha soo socda:

1. stroke ischaemic Ba'an.
2. dhaawac maskaxda ah oo daran. Marka dhaawac maskaxda si looga fogaado jabka lafaha qalfoofka la aqbalo in la sameeyo X-ray ee madaxa. MRI, si kastaba ha ahaatee, u ogolaanaya in ay arki ma aha oo kaliya dhaladii, laakiin sidoo kale gobolka ee dhismayaasha intracranial.
3. Calaamadaha hypertension intracranial. Xaaladdan oo kale, aqoonsiga ah marka laga reebo ama mugga intracranial la taaban karo loo fududeeyo formation of sawirada oo israac raacsan. MRI ee maskaxda ee hypertensive syndrome magacaabi si loo xaqiijiyo cudurka sida hematoma intracranial, intracranial buro, malax maskaxda.
4. Cillado marinnada cerebral.
5. la socodka xaaladda ka dib markii qaliin neurosurgical.
6. MRI caawisaa sawirka faahfaahsan oo dhigay meesha iyo (in tijaabooyin lagu celiyo), dhaq-neuromas iyo qaababka fibrosis.

Garashada cudurada spinal

Magnetic resonance imaging waa hab fiican oo in la ogaado xaaladaha cudur-dhabarta.

Natiijadan ayaa waxa ay noqon doontaa hab lagu ogaanayo sawir faahfaahsan heerarka.

MRI dhabarta thoracic waxa lagu qoray ka muujinaya soo socda:

• Xanuun syndrome ee etiology la aqoon goobta xabadka - si looga fogaado in formation of kansarka hoose ama nabar xadka-.
• calaamadaha dareemayaasha, jidaynayey joogitaanka Sheelada intervertebral.
• Nidaamka waa dabaqi karo labada qalliinka ka hor iyo ka dib waxay - si loo xakameeyo dhaq-geedi socodka dib u soo kabashada.
• Dhaawaca la jab tuhunsan yahay xabadka - si looga fogaado dhaawac lafta. Tan iyo raajito loogu bixisaa faahfaahsan oo ah marsiiyey image ah, waa taageero dheeraad ah ee ka mid ah xaaladaha badan ee X-ray.

MRI ee lumbar uu leeyahay qiimo lagu ogaanayo in arrimaha soo socda:

• Cabashooyinka xanuun gobolka lumbosacral, la'aanta ah ee waxtarka waxbarashada X-ray.
• Ka dib markii dhaawac aagga this - si looga fogaado laftayda iyo dhaawacyo.
• Marka cudurka jab-dhabarta, qasan by barakac jajabkii lafta - si loo caddeeyo inta uu la egyahay barakaca, fogaado dhaawac carjawda intervertebral, xuubka iyo xangulada.
• Waayo, cudurka kala duwan ee isbedel side ah dhabarta iyo araxda sabab u ah burburinta lesions xadka- ah.
• calaamadaha dareemayaasha muujinaysa cuncun ama riixo xididka dareemayaasha riixo sababa in la cayimay, oo kiiskan, waayo cudurka barakaca vertebral, iyo waa ku filan si ay u sameeyaan ah X-ray. MRI dhabarta lagama maarmaanka ah si ay u fuliyaan si ay u aqoonsadaan cudurada unugyada nerentgenokontrastnyh (barakaca ee disc ah intervertebral, disc herniated, barar bararka, compressing riixo xididkii dareemayaasha buro keenaya).
