Raajito loogu xisaabiyaa ama magnetic resonance imaging - taas oo ka wanaagsan iyo waxa faraqa u?

Tiro weyn ee cudurrada iyo dhaawacyada lagu ogaan karaa oo kaliya on calaamadaha soo bandhigay. Inta badan dadka jiran in ay raadsadaan daryeel caafimaad, khubarada u yeelaan computer (CT) iyo resonance magnetic (MR) imaging. Waa maxay waxa loo yaqaan daraasadda? raajito loogu xisaabiyaa ama magnetic resonance imaging - taas oo ka wanaagsan? In arrimahan, waxay ka caawisaa si ay u fahmaan.

KOOBAN lagu xisaabiyaa si raajito

CT - hab lagu ogaanayo jeediyay sanadkii 1972. Qubarada ayaa waxaa la horumariyo sabab u tahay xaqiiqda ah in raajada caadiga ah Wax La Isbamariyay. Waxa ay u ogolaataa xirfadlayaasha ee sahanka bukaanka shaqsi si ay u helaan oo keliya hal shot. In si raajito loogu xisaabiyaa isku miisaan faa'iidooyinka. Waa midda koowaade, in habkan lagu ogaanayo mahad heli kartaa tiro ka mid ah images. Second, sanamyadii ma jiraan qasayso hooska. Saddexaad, at dareen CT uu ka sareeyo marka la barbardhigo raajada caadiga ah.

raajito loogu xisaabiyaa ku salaysan yahay isticmaalka X-rays. Marka aad isticmaasho habkan ogaanshaha isticmaalaa scanner gaar ah. nidaamka software-hardware adag Tani, oo ka kooban:

• u eegis (qayb guurtada ah qalab ka kooban qalabka iskaanka);
• matoor danab sare;
• Console operator;
• nidaamka kombiyuutarka.

Tilmaamayaasha for lagu xisaabiyaa si raajito

CT ka fiican tahay farsamooyinka kale visualizes lafaha. Taasi waa sababta habkan lagu ogaanayo waxa loo isticmaalaa aqoonsanayo bukaan aadanaha dhaawacyo kala duwan, jab. Tusaale ahaan, nin dhakhtar ah su'aasha ah: "? Waa kuwee waa ka wanaagsan - MRI ama raajada CT-dhabarta" Haddii uu jiro takhasus dhaawac magacaabay CT. Daraasad Tani waxay noo oggolaaneysaa in ay bartaan gobolka ee geedi socodka araxda, saxanno intervertebral.

raajito loogu xisaabiyaa waxaa sidoo kale loo xilsaaray in arrimaha soo socda:

• waayo, stroke looga shakisan yahay;
• dad ku sugan xaalad halis ah,
• sababo si ay u qabtaan MRI.

CT la sameyn karaa oo wakiilka ka duwan ah. Waxaa la soo bandhigay galay jidhka ee bukaan-socodka mawduuca si loo wanaajiyo kaladuwan oo ka mid ah xubnaha gudaha marka laga reebo. Wakiilka duwan ayaa sidoo kale waxay ka caawisaa si ay u caddeeyaan nooca dhismeedka bahal la ogaado oo la garto isbeddel ah in aan la arki karin ee waxbarashada caadiga ah.

Sababo in lagu xisaabiyaa si raajito

Sayidka, xisaabiyaa si raajito ama resonance imaging magnetic - taas oo ka wanaagsan? At CT, iyo sidoo kale hab kale oo wax lagu ogaanayo, waxaa jira contraindication ah. Daraasadda, fuliyay iyada oo aan la barbardhigo iyo duwan, lagu qorin,

• haweenka uurka leh, sababtoo ah shucaac X-ray waxay leedahay saameyn xun ku uurjiifka,
• sidoo kale dadku ka buuxay, maxaa yeelay sifooyinka farsamo ee scanners ah, waxaa jira calaamado muujinaya in mass ugu badan ee kaas oo qalabka waa in ay hor istaagi karo.

In si raajito loogu xisaabiyaa, fuliyay kula hordhaca ah ee wakiilka ka duwan ah, waxaa jira sababo dheeraad ah. xasaasiyadda iyo kilyaha, iyo noocyo kala duwan oo cudurka thyroid iyo diabetes daran, iyo myeloma, iyo xaaladda qabriga bukaanka hoos baaritaanka.

Waa maxay MRI?

Hab kale oo ka mid ah cudurka - MRI. Habka Sahankan wuxuu la asaasay 1973. raajito loogu xisaabiyaa ama magnetic resonance imaging - taas oo ka wanaagsan? In ka jawaabin su'aashan, waxaa jira dhowr Faa'iidooyinka imaging resonance magnetic in CT:

• fiican xallinta ;
• joogitaanka suurtagalnimada helo qaybaha kala duwan ee diyaaradaha,
• Marka la barbardhigo image weyn.

oo lagu daray ugu weyn ee magnetic resonance imaging waa in gaadhista gamma-ray in mawduuca aadanaha ma aha. Sababtuna waxay tahay, in MRI wuxuu ku salaysan yahay arrin of resonance magnetic nuclear, halkii shucaaca X-ray ah. Waayo, fulinta scanners imaging resonance magnetic isticmaali aad u kala duwan. qalabka MRI ka kooban yahay magnet, Wehliyaha, shimmiruyuschih iyo gariiradda inta jeer ee radio, nidaamka qaboojinta, helo nidaamyada, xogta isugu gudbiyo iyo processing, baarista nidaamka.

Tilmaamayaasha for magnetic resonance imaging

MRI waxaa loo xilsaaray in ay dadka marka lagu tilmaamay. Kuwaas waxaa ka mid ah:

• inflammations;
• cudurada lagu dhasho, aan caadi ahayn horumarineed;
• dhaawacyada,
• xanuunada vascular,
• neoplasms.

raajito loogu xisaabiyaa ama magnetic resonance imaging - taas oo ku fiican yahay go'aaminta burada? Tani waxay dad badan oo ka codsanaynaa. Magnetic resonance imaging waa visualizes fiican unug jilicsan. dhismayaasha Bony ma saameyn tayada sanamyadii. Taasi waa sababta dhakhtarrada looga shakiyay neoplasm qori MRI.

Sababo in magnetic resonance imaging

Marka jawaabay su'aasha ah: "si raajito loogu xisaabiyaa ama magnetic resonance imaging - taas oo ka wanaagsan" - waa in la ogaadaa in resonance imaging magnetic ayaa sidoo kale waxaa lagu qori karaa in aan dadka oo dhan. sababo Absolute ee habkan of diagnosis ka mid ah:

• joogitaanka qalabka elektarooniga ah non-saari karo;
• joogitaanka ee jirka ka mid ah meydadka ajnabiga ah macdan ah,
• joogitaanka of aneurysms intracranial, wax ferromagnetic klipirovannyh;
• joogitaanka tattoos on jidhka la content ee xeryahooda macdan ah.

sababo Qaraabo yihiin:

• hore ee uurka,
• cagajugleynta,
• xanuun aad u daran oo aan u ogolaan in weli lagu jiro daraasada;
• anshax xumada sabab u ah daroogada ama khamriga;
• baahida loo qabo in lala socdo calaamadaha muhiimka ah.

Magacaabidda CT iyo MRI: tusaalooyin

Taas oo ka mid ah hababka of diagnosis waa ugu wargelin ah? In ka jawaabin su'aashan, ma aan samayn karo iyada oo aan tusaalayaal. Waxaan ka fiirsan karaa imtixaanka ka mid ah kelyaha. Lagu xisaabiyaa si raajito ama MRI? Waa maxay roon kelyaha? Marka dhibaatooyinka caabuq ba'an, dhakhaatiirta qori ultrasound. Qaabkan ogaanshaha aasaasiga ah si ay u qiimeeyaan dhinacyada parenchyma kelyaha baruurta perirenal gobolka dhismeedka. Si loo qiimeeyo heerka of iyo isbedel bararka ee si faahfaahsan loo xilsaaray si raajito loogu xisaabiyaa.

Haddii inta lagu guda jiro ultrasound shaaca ka qaaday formation cyst adag ama adag, sharaxaad ka waxaa la fuliyaa iyadoo CT duwan si loo caddeeyo cudurka (wakiilka duwan si weyn u kordhiyaa content macluumaadka). Marka natiijada maqlana tusi magnetic resonance imaging.

Tusaalaha soo socda - kormeerka aadanaha iyadoo looga shakisan yahay stroke ischaemic. Lagu xisaabiyaa si raajito ama MRI? Waa maxay roon maskaxda, qiimeeyaan ay yaqaannaa cudurka xaaladda? raajito loogu xisaabiyaa waxaa la sameeyaa maalinteedii kowaad. Waxay kuu ogolaanaysaa inaad ka horjoogsanaya in haemorrhage. Laakiin iyadoo la kaashanayo MRI this waxaa la samayn karaa. Magnetic resonance imaging waa in subacute (3-14 maalmood) oo chronic (in ka badan 14 maalmood) marxaladaha sare oo keliya.

Sayidka, cidna ma dhihi karto oo ka mid ah hababka of diagnosis waa ugu wargelin ah. raajito loogu xisaabiyaa ama magnetic resonance imaging - taas oo ah roon dhabarta, kelyaha, maskaxda iyo xubnaha kale ee gudaha? Jawaabta su'aashan waa dhakhtar for kiis kasta oo gaar ah. Oo si raajito loogu xisaabiyaa, oo imaging resonance magnetic - laba hab wargelin ah. Doorashada u dhaxeeya iyaga waxaa had iyo samaynta takhasuska, la siiyaa sawir caafimaad oo ah, gobolka qofka buka, jiritaanka cudur.
