Itomography ngekhompyutha okanye ngemagnethi livakale umfanekiso - nto leyo ngcono kwaye yintoni umahluko?

Inani elikhulu kwezifo kunye nokwenzakala ukuba unesifo kuphela ezi mpawu ukubonwa. Kakhulu wayegula abantu bafuna ukunyangwa, iingcali ayabele icomputer (CT) kunye nemagnethi ekuvakaleni kwelizwi (MR) ufaniso. Yintoni zibizwa isifundo? Itomography ngekhompyutha okanye ngemagnethi livakale umfanekiso - kokona kulungileyo? Kwezi zinto, kuyanceda ukuqonda.

ISISHWANKATHELO ngekhompyutha Itomography

CT - indlela diagnostic ecetywayo ngo-1972. Izazinzulu ziye zaphuhliswa ngayo ngenxa yokuba ray eqhelekileyo bayasilela. It ivumela Iingcali kwisaveyi yomguli ngamnye lokufumana sadubula omnye kuphela. In ngekhompyutha Itomography iingenelo efanayo ubunzima. Okokuqala, ngenxa kule ndlela diagnostic Ungayifumana iqela imifanekiso. Okwesibini, imifanekiso akukho thunzi lwe alpha. Okwesithathu, xa uvakalelo CT iphezulu xa kuthelekiswa ray yesiqhelo.

Itomography ngekhompyutha isekelwe phezu ukusetyenziswa kwe-X-reyi. Xa usebenzisa le ndlela diagnostic isebenzisa isithwebuli okhethekileyo. Le nkqubo software-hardware enzima, eziquka:

• gantry (inxalenye eshukumayo ye izixhobo eliquka izixhobo ukuskena);
• umvelisi ombane aphezulu;
• console umqhubi lowo;
• computer system.

Ubungqina obubonakalayo buxela ukuba Itomography ngekhompyutha

CT engcono kunezinye iindlela obonisa ithambo. Kungenxa yoko le nto kusifikeleyo oku ndlela diagnostic lisetyenziswa ekuchongeni abantu abagulayo yokwenzakala ezahlukeneyo, waphuka. Ngokomzekelo, enye indoda waya kwagqirha kunye umbuzo: "? Kukuphi na okulunge ngakumbi - MRI okanye CT scan yomqolo" Ukuba kukho liyincutshe kukwenzakala umisa CT. Olu phando kusivumela ukuba phando imeko omqolo lweenkqubo, intervertebral akwazi.

Itomography ngekhompyutha nayo wabelwa kwezi meko zilandelayo:

• nezeStrowuku okusolwayo;
• komuntu embi imeko;
• Izimo ukuqhuba MRI.

CT unako kubhalwa nge-arhente umahluko. Kokuba usiwe kwi umzimba zesifundo umguli ukwenzela ukuphucula iyantlukwano zangaphakathi izitho bebodwa. Iarhente umahluko kwakhona kunceda ukucacisa ngobume bezakhelo zophendlo lwezifo esifunyenweyo uchonge utshintsho abangakwaziyo kungabonwa kwizifundo eziqhelekileyo.

Izimo ku ngekhompyutha Itomography

Ngenxa yoko, ngekhompyutha Itomography okanye livakale magnetic umfanekiso - kokona kulungileyo? E CT, kwakunye nayiphi na enye indlela edla umzi, kukho contraindication. Esi sifundo, yenziwe ngaphandle uthelekiso kunye koko, akukho wabelwa:

• kumabhinqa, ngokuba le X-reyi imitha has a elibi nefuthe ekukhuleni kosana olungekazalwa;
• kakhulu ngokupheleleyo abantu, kuba iimpawu zobugcisa yabavavanyi, kukho iimpawu ezibonisa ukuba ubunzima ubuninzi apho izixhobo ziyakwazi ukumelana.

Xa Itomography ngekhompyutha, salwenza kunye ukusungulwa arhente koko, kukho Izimo ezongezelelweyo. Lo mngundo kunye ukusilela kwezintso, kunye neentlobo ngeentlobo isifo lengqula, kunye seswekile, yaye ezigula ezininzi, kunye nemeko engcwabeni yesigulana phantsi uviwo.

Yintoni MRI?

Enye indlela loxilongo - MRI. Olu phando ndlela yasungulwa ngo-1973. Itomography ngekhompyutha okanye ngemagnethi livakale umfanekiso - kokona kulungileyo? Xa uphendula lo mbuzo, kukho iingenelo eliqela otsalayo livakale bemifanekiso CT:

• esihle resolution ;
• Phambi Ukuphandwa ngokufumaneka amacandelo ahlukeneyo iindiza;
• umahluko umfanekiso omkhulu.

Eyona plus ezingundoqo otsalayo livakale umfanekiso kukuba sesichengeni gamma-ray kumxholo womntu. Isizathu kukuba MRI isekelwe phezu mba ekuvakaleni kwelizwi magnetic enyukliya, kunokuba radiation X-ray. Zokuyenza loo livakale magnetic umfanekiso yabavavanyi ukusebenzisa eyahlukileyo kakhulu. Izixhobo MRI luqulathe iimagnethi, ithambeka, shimmiruyuschih kunye imibhijelo sokuquqa kwerediyo, iinkqubo zokupholisa, sisamkela iinkqubo, zodluliselo lwedata kunye nokulungiswa, ukuhlolwa iinkqubo.

Ubungqina obubonakalayo buxela ukuba magnetic ekuvakaleni kwelizwi umfanekiso

MRI wabelwe abantu xa kuboniswe. Ezi ziquka:

• inflammations;
• izifo bekhubazekile, ukungaqheleki zophuhliso;
• ukuphatheka;
• izifo yegazi;
• neoplasms.

Itomography ngekhompyutha okanye ngemagnethi livakale umfanekiso - nto ingcono kwi ukulinganisa ithumba? Aba bantu abaninzi abayicelayo. Magnetic intlokoma umfanekiso na obonisa ezigqwesileyo inyama ithambile. izakhiwo nokudleka akazange kuchaphazela umgangatho imifanekiso. Kungenxa yoko le nto oogqirha bethengisa neoplasm kwenkcazo MRI.

Izimo ukuba magnetic ekuvakaleni kwelizwi umfanekiso

Xa uphendula lo mbuzo: "Itomography ngekhompyutha okanye ngemagnethi livakale umfanekiso - kokona kulungileyo" - kufuneka kuqatshelwe ukuba livakale magnetic umfanekiso nazo zabelwe ukuba abantu bonke. Izimo Absolute yale ndlela loxilongo ziquka:

• ubukho izixhobo non-abasusekayo electronic;
• ubukho kumzimba imizimba zalo kwamanye amazwe;
• ubukho aneurysms intracranial, izinto klipirovannyh ferromagnetic;
• phambi iithathu emzimbeni ikhontenti zalo zakhi.

Izimo isihlobo:

• ekuseni nokukhulelwa;
• bephelelwa umoya;
• ubuhlungu obukhulu awuvumeli ukuba ukubamba cwaka ngethuba lophando;
• ukuziphatha engafanelekanga ngenxa yotywala okanye iziyobisi;
• imfuneko yokuba kubekwe iliso iimpawu ezibalulekileyo.

Ukuqeshwa CT kunye MRI: imizekelo

Yeyiphi kwezi ndlela loxilongo kukuthi kakhulu efundisayo? Xa uphendula lo mbuzo, Asinakuyenza ngaphandle imizekelo. Sinako ingqalelo iimviwo ze nezintso. Ngekhompyutha Itomography okanye MRI? Yintoni ezingcono izintso? Xa iingxaki ukudumba ludlule, oogqirha ukumisela ultrasound. Le ndlela iphambili kokuxilongwa ivumela ukuba ukuqikelela ubungakanani kidney, isakhiwo parenchyma, perirenal imeko ngamanqatha. Ukuvavanya ukuxhaphaka kunye notshintsho yokukrala iinkcukacha abayabelwe Itomography ngekhompyutha.

Ukuba ngexesha ultrasound lubonise ukuyilwa cyst eqinileyo okanye inzima, inkcazelo lwenziwa ne nshita CT ukucacisa uxilongo (arhente umahluko kwandisa kakhulu isiqulatho ulwazi). Xa edidayo iziphumo zibonisa ngemagnethi ekuvakaleni kwelizwi ufaniso.

Lo mzekelo ulandelayo - uhlolo lomntu kuyakrokreleka stroke kobuchopho. Ngekhompyutha Itomography okanye MRI? Yintoni na okulunge ngakumbi ingqondo, ukuhlola imeko ngokuba sisifo wayo? Itomography ngekhompyutha lwenziwa ngosuku lokuqala. It likuvumela ukwahlula Ukopha ebuchotsheni. Kodwa ngoncedo MRI oku kunokwenziwa. Magnetic intlokoma umfanekiso yeyona kakhulu kuphela subacute (3-14 imini) kunye ezigulo ezondeleyo (iintsuku ezingaphezu kwama-14) izigaba.

Ngaloo ndlela, umntu athi zeziphi na iindlela loxilongo yeyona ulwazi. Itomography ngekhompyutha okanye ngemagnethi livakale umfanekiso - nto leyo ilungileyo yomqolo, izintso, ingqondo kunye nezinye izigqeba zangaphakathi? Impendulo yalo mbuzo ngugqirha nganye kwimeko ethile. Kwaye Itomography ngekhompyutha, yaye livakale magnetic umfanekiso - ezimbini indlela ngokufundisayo. Ukukhetha phakathi kwabo kusoloko kusenziwa ziingcali, banikwe unyango mfanekiso, imeko zabagulayo mntu, phambi sifo.
