Yintoni obahlukileyo ukusukela MRI CT? Kwezinye iimeko, MRI CT ingcono?

inqanaba yeza okwangoku kakhulu eliphezulu. Zininzi izifundo eziya kubavumela ukuba basibone ngokuchanekileyo. Xa yokugcina kumagqirha - ubuchwepheshe yakutshanje. Ngoncedo lwabo kube lula ukuba sijonge ngaphakathi emzimbeni iwabonakalalise ngezifo kuphuhliso okanye ukusebenza izibilini.

Ezi iindlela ezintsha diagnostic ziquka livakale Imagnethi yomhlaba kunye Itomography ngekhompyutha. Ezi zifundo sele zisetyenziswa ukuqinisekisa uxilongo. Uninzi lwezi nkqubo ngaphandle bathunyelwe kagqirha. Kulo mzekelo, kubalulekile ukwazi umahluko phakathi MRI ku CT.

isimiso ukusebenza

Nangona isibakala sokuba ngenxa zombini izifundo ezifunyenwe umfanekiso-onamacala amathathu enyama yangaphakathi, kukho umahluko ebalulekileyo phakathi kwabo:

• Ngokutsho neqondo uvakalelo.
• Xa umgaqo amanyathelo.

CT isikeni isebenza ngokusebenzisa -X-reyi. Kuyinto lonke ufakelo, yokubolekisana ngeenxa emzimbeni wakhe, ithatha imifanekiso. Yonke mifanekiso ke adityaniswe, kunye nonyango kwabo inxaxheba kule khompyutha.

Ngokungafaniyo MRI CT ngokusisiseko esebenza kukuba apha akukho X-ray, kwaye wokunceda umntu kuba amasimi ngemagnethi. Phantsi yempembelelo athom hydrogen ezikhoyo omzimba wesigulane, elungelelaniswe ngaxeshanye magnetic ulwalathiso endle.

Le fowuni uthumela ubume RF, leyo nkqo endle main ngemagnethi. Esikule emzimbeni womntu angene intlokoma livakale zaze ke ezi seli vuavanyisi ezinokubona, ukususa kubo nokwakha nemifanekiso sekhombuya.

Iimpawu ze-MRI ne- CT iinkqubo

Kukho izifo apho akukho mahluko ebonakalayo, yintoni baphande uza kudlula. Njengoko omnye, kwaye iyunithi yesibini iya kuba nako ukunika umphumo echanileyo.

Noko ke, kukho izinto ezimbi apho kubalulekile ukuqwalasela ukuba ngcono - MRI okanye CT?

MRIs evame ukunikezwa xa kukho imfuneko yokuba uviwo eneenkcukacha inyama ithambile emzimbeni, luvo, izihlunu kunye namalungu. On le mifanekiso zonke ezimbi ziphawulwe kakuhle.

Kodwa inkqubo skeletal ngenxa isiqulatho encinane protons hydrogen kakubi Ilandela kwimitha Imagnethi, kwaye umphumo kuba zichanile ngokupheleleyo. Kule meko ke kungcono ukuba aqhube CT scan.

CT ubuye abe nakho ukunika umfanekiso wenene sifundo amalungu ezibuhlazarha ezifana esiswini, amathumbu kunye nemiphunga.

Ukuba uthethe izifo, i-MRI iboniswa ukuba:

• Stroke.
• Uxilongo izifo amalungu zangasese.
• Isifundo uqhoqhoqho, emphinjeni kunye imithambo yegazi.

CT scan kungcono ukuba kuqhuba isaveyi:

• isixokelelwano sokuphefumla.
• Kidney.
• Amalungu kwisisu.
• Skeletal system.
• Xa ekuxilongweni indawo ngqo iingozi.

Ngoko ke, kuyacaca ukuba MRI kunye CT umahluko siyifumana amanqaku ezahlukeneyo isicelo.

Izimo iinkqubo

Nangona impumelelo yayo, zombini izixhobo kufuneka Izimo. Kaninzi izigulane inkunkuma ayinakubalwa Itomography ngenxa yokoyika-X-reyi. Ekuphenduleni lo mbuzo oko kukuthi ekhuselekileyo, MRI okanye CT scan, banokuthi babe nomdla kukhetho lo isifundo sokuqala.

A Uqwalaselo olubukhali nga kuqatshelwe ukuba zombini iintlobo uye Izimo yayo.

Yintoni obahlukileyo ukusukela MRI CT, ukuba imbonakaliso yabo. Itomography ngekhompyutha ayiboniswanga:

1. abafazi abakhulelweyo (ngenxa ukusuleleka kwemitha ukuya kwimveku).
2. abantwana abaselula.
3. Ngokuba rhoqo.
4. Xa ubukho gypsum kwinkalo yophando.
5. In insufficiency kwezintso.
6. Ngexesha lokuncancisa.

Magnetic intlokoma umfanekiso une Izimo yayo:

1. Bephelelwa, xa umntu kuba esoyika spaces ezivaliweyo.
2. Ukubakho kumzimba ka-ntliziyo.
3. Le ezintathu zokuqala zokukhulelwa.
4. ubunzima Large emzimbeni (110 kg).
5. Ukubakho efakwe iintsimbi, umzekelo, kwamalunga.

Zonke ezi zinto Izimo ngokupheleleyo, kodwa phambi kokuba inkqubo, kufuneka udibane nogqirha wakho, mhlawumbi xa ityala lakho nazo iingcebiso ezithile.

Izinto eziluncedo magnetic ekuvakaleni kwelizwi umfanekiso

Ukuze uqonde ukuba yintoni na ngcono - MRI okanye CT scan, kufuneka ucinge inzuzo uhlobo ngalunye lwe sifundo.

Magnetic intlokoma umfanekiso has a lot of iinkalo ezintle:

• Yonke ingcaciso ichanekile kakhulu.
• Le ndlela yeyona okucacileyo ukufunda izigulane izitshanguba inkqubo luvo.
• Ukubamba nokuxilonga Ithemba vertebral.
• It is a uviwo ekhuselekileyo abasetyhini abakhulelweyo kunye nabantwana.
• Ingasetyenziswa nge nezihlandlo into oyifunayo.
• Ngokuqinisekileyo elula.
• Wafumana imifanekiso-ntathu.
• Kuyenzeka ukugcina ulwazi kwinkumbulo yekhompyutha.
• Amathuba okufumana ulwazi engalunganga phantse zero.
• Akukho exposure X-ray.

Xa sijonga iimpawu isixhobo nangemigaqo yayo yokusebenza, ngexesha lesifundo inokuba inkqonkqoze elikhulu, nto leyo akuyomfuneko ukuba woyike, ungasebenzisa headphones.

Izinto eziluncedo ngekhompyutha Itomography

Ngembonakalo, zombini tomograph ziyafana kakhulu. Isiphumo yomsebenzi wabo nalo kuphela imveliso amacandelo ezingcakacileyo kwimimandla bafunda ngomfanekiso. Ngaphandle isifundo iinkcukacha kunzima kakhulu ukuba umahluko phakathi MR ukuba CT.

Izinto eziluncedo ze CT ziquka ezi zibakala zilandelayo:

1. Kubonakala umfanekiso-ntathu balo mmandla uphononongwayo.
2. imifanekiso ecacileyo skeletal system.
3. Akukho iintlungu ngexesha nkqubo.
4. yonke Uphononongo kuthatha imizuzu embalwa.
5. Ekunyaniseni nokuthembeka kolwazi.
6. MRI inika yedosi esezantsi radiation ngaphezu umatshini X-ray.
7. Ngaba kujongisiswa phambi ngesinyithi okanye zombane izixhobo emzimbeni.
8. Inika ulwazi lokwenyaniso oluchanileyo ukopha ngaphakathi, Ubhaqo ithumba.
9. iindleko Lower kuthelekiswa MRI.

Njengoko ubona, ngeskena CT akukho ndlela ngaphantsi ngani ekuvakaleni kwelizwi magnetic, kangangokuba kungcono - MRI okanye CT, kufuneka iqwalaselwe xa kwimeko nganye.

Ezingeloncedo uhlobo ngalunye yophando

Ngelo xesha langoku phantse zonke iintlobo ngophengululo bobabini iinkalo ezintle kunye nobubi. Yabavavanyi kulo mba kungekho ngaphandle.

Bobubi MRI Diagnostics ezi zibakala zilandelayo:

• Kunzima ukufunda amalungu ezibuhlazarha ezifana wokuchama nenyongo isinyi, imiphunga.
• izahlulo metal emzimbeni womntu uya kuba yimiqobo le nkqubo.
• Kufuneka ixesha elininzi ukulungiselela isifundo.
• Ukuze ufumane iziphumo lokwenyaniso nezichanekileyo kangangexesha elide isigulane kufuneka ibe kwindawo elimisiweyo.

Kwikhompyutha Itomography Okungancediyo:

• Uphononongo ayiboneleli ngolwazi malunga sokusebenza ngamalungu kunye namalaphu, kodwa kuphela kwisakhiwo sabo.
• Imiphumo eyingozi -X-reyi.
• Contraindicated abafazi abakhulelweyo kunye nabantwana.
• Le nkqubo ayikwazi wenziwe rhoqo.

Ukuba wena Kunconywa ukuba zombini iindlela zophando, kulo mzekelo, akukhathaliseki kakhulu obahlukileyo ukusukela MRI CT.

iindlela ezifundisayo

Emva kokutyelela ugqirha, uya kucwangciselwa uhlolo, leyo, ngokoluvo ugqirha, ukunika isiphumo lokwenyaniso echanekileyo.

Ukuba ugqiba ukuba silinde iingcebiso, kuyimfuneko ukwazi apho iimeko apho icebo ukukhetha.

Ukuba awuyazi into ngqo - MRI okanye CT scan, khumbula ukuba MRI uza kubonelela iziphumo ezichanekileyo kwaye ulwazi phantsi ezimbi zilandelayo:

1. ithumba ebuchotsheni, stroke kunye multiple.
2. Zonke izifo umnqonqo.
3. ngezifo Intracranial le luvo kunye ingqondo.
4. Umonakalo izihlunu kunye nemisipha.
5. inyama ithumba Soft.

Ukuba yanyhashwa imisebenzi ebalulekileyo, kuyimfuneko ukuba siqhube uthethwano kunye nogqirha wakho.

Ezichanisekileyo ulwazi CT intando, ukuba ikhona:

• Eko yokopha intracranial, ukuphatheka.
• Umonakalo kunye nesifo ithambo.
• Pathology ye isixokelelwano sokuphefumla.
• izilonda Atherosclerotic yegazi.
• Izitshanguba ngamathambo yobuso, lengqula.
• Otitis kunye sinusitis.

isifundo ipreoperative ziya kunika umfanekiso echanekileyo kwi utyando ezayo.

Ukuba okholelwayo uxilongo kukrokrelwa, kwaye ungakhetha indlela yakho uphando.

Umahluko omkhulu iindlela

Nangona ukufana ezininzi kangaka, umahluko phakathi CT kunye MRI isekhona. Ukuba kukho iingongoma ezimbalwa, ngoko ke sithi oku kulandelayo:

1. Umahluko ebaluleke kakhulu phakathi kwezi ndlela zimbini yophando ilele umgaqo zabo zokusebenza. MRI isebenzisa Imagnethi yomhlaba, kunye CT --x reyi.
2. ingasetyenziswa zombini iindlela ukuxilonga inani kakhulu ezimbi.
3. Ngenxa yoko okufanayo kulinga kukhetho MRI, njengoko olu phando luba ngakumbi, kodwa ibiza kakhulu.
4. inkqubo ngamnye Izimo zalo, ngoko ke kufuneka ukuba ziqwalaselwe phambi kokuba enze isigqibo sokugqibela.

Khumbula, impilo yakho ezandleni zakho, kwaye ngamanye amaxesha akunamsebenzi uhlobo ndlela diagnostic esetyenzisiweyo ntoni, eyona nto ibalulekileyo - ukufumana ixesha elungileyo echanileyo unenyaniso yaye ukuze uqale unyango.
