Tomography ngekhompyutha noma-magnetic resonance imaging - okuyinto engcono futhi uyini umehluko?

Inani elikhulu of izifo futhi ukulimala kungenza ihlonzwe kuphela izimpawu embukisweni. Esikhathini esiningi abantu abagulayo usizo, ochwepheshe nika ikhompyutha (CT) kanye resonance kazibuthe (MR) imaging. Yini abizwa ngokuthi ucwaningo? tomography ngekhompyutha noma-magnetic resonance imaging - okuyinto engcono? Kulezi izindaba, kuyasiza ukuqonda.

SUMMARY ngekhompyutha tomography

CT - indlela zokuxilonga ehlongozwayo 1972. Ososayensi baye basungula ke ngenxa yokuthi esimweni ezivamile zazinamaphutha. It ivumela ochwepheshe inhlolovo isiguli ngamunye ukuthola shot eyodwa kuphela. Ngo ngekhompyutha tomography efanayo isisindo izinzuzo. Okokuqala, sibonga le ndlela zokuxilonga bengathola eziningi izithombe. Okwesibili, izithombe Awekho kwendingilizi isithunzi. Okwesithathu, ukuzwela CT lingaphezulu uma ziqhathaniswa esimweni ezivamile.

computed tomography kusekelwe ukusetshenziswa kuma-X ray. Uma usebenzisa le ndlela zokuxilonga isebenzisa isithwebuli ekhethekile. Lokhu kuyinkimbinkimbi uhlelo software-hardware, ehlanganisa:

• gantry (ingxenye ezithathekayo we-apharathasi ehlanganisa imishini ukuskena);
• generator high voltage;
• console opharetha;
• ikhompyutha ohlelweni.

Izimpawu ze-ngekhompyutha tomography

CT kangcono kunamanye amasu Ziveza ithambo. Yingakho le ndlela zokuxilonga isetshenziswa sizibone iziguli womuntu yokulimala ehlukahlukene, waphuka. Ngokwesibonelo, Indoda yaya kudokotela ngombuzo: "? Yikuphi okungcono - MRI noma-CT scan umgogodla" Uma kukhona uchwepheshe ukulimala uqoka CT. Lolu cwaningo kusivumela ukufunda isimo izinqubo amathambo, akwazi ukugcina intervertebral.

computed tomography bunikezwe kulezi zimo ezilandelayo:

• I-stroke esolwa;
• isidalwa esingumuntu usesimweni esibucayi;
• Izimo ukuqhuba i-MRI.

CT ingasatshenziswa nge ejenti ukuze kuvele umehluko. It is busuka umzimba wesiguli kuncike ukuze uthuthukise kwamangqamuzana kwezitho zangaphakathi ngaphandle. I-ejenti Ngokuphambene nakho kuyasiza ukucacisa ubunjalo Kutholwe izakhiwo sokugembula futhi ukukhomba izinguquko ingabonakali ezifundweni ezivamile.

Izimo ngekhompyutha tomography

Ngakho, ngekhompyutha tomography noma resonance kazibuthe imaging - okuyinto engcono? Ngezinye CT, kanye nanoma yimuphi omunye indlela zokuxilonga, kukhona contraindication. Lolu cwaningo, eyenziwa ngaphandle ukwahlukana Ngokuphambene, is alinikeziwe:

• abesifazane abakhulelwe, ngoba emisebeni-X-ray kunomthelela ongemuhle embungwini;
• kakhulu egcwele abantu, ngoba izici lobuchwepheshe lwemishini, kunezinkomba zokuthi mass esiphezulu yimaphi amadivayisi akwazi ukumelana.

Ngo computed tomography, eyenziwa nge ukwethulwa ejenti Ngokuphambene, kukhona Izimo ezengeziwe. Lokhu yokungezwani komzimba futhi ukwehluleka kwezinso, futhi ezihlukahlukene abanale nkinga futhi esibi sikashukela, futhi myeloma amaningi, futhi isimo ithuna isiguli ngaphansi luhlolo.

Kuyini MRI?

Enye indlela uphethwe - MRI. Le ndlela inhlolovo yasungulwa ngo-1973. tomography ngekhompyutha noma-magnetic resonance imaging - okuyinto engcono? Ekuphenduleni lo mbuzo, zikhona izinzuzo eziningana-magnetic resonance imaging ukuba CT:

• kakhulu isinqumo ;
• khona ukuthi kungenzeka ukuthola izingxenye e izindiza ezahlukene;
• elikhulu isithombe umehluko.

I plus eyinhloko-magnetic resonance imaging ukuthi gamma-ray ukuchayeka isihloko womuntu awuwona. Isizathu siwukuthi MRI kusekelwe lo mkhuba zenuzi resonance kazibuthe, kunokuba emisebeni-X-ray. Sokufeza-magnetic resonance imaging scanner zisebenzisa ezahlukene kakhulu. amadivaysi MRI aqukethe odonsa, umyela, shimmiruyuschih futhi omsakazo ohlobo, Ukupholisa izinhlelo, ethola izinhlelo, idatha ukuwudlulisa ukucutshungulwa, ukuhlolwa izinhlelo.

Izimpawu I-magnetic resonance imaging

MRI inikezwa abantu lapho kuboniswe. Lezi zihlanganisa:

• inflammations;
• izifo azalwa naso, kwezinso entuthuko;
• ukuhlukumezeka;
• iziyaluyalu semithambo;
• neoplasms.

tomography ngekhompyutha noma-magnetic resonance imaging - okuyinto kangcono ekutholeni isimila? Lokhu abantu abaningi babuze. Magnetic resonance imaging kuyinto Ziveza kakhulu izicubu zomzimba ezithambile. izakhiwo Bony akazange kuthinte izinga izithombe. Yingakho odokotela neoplasm esolwa linqume MRI.

Izimo-magnetic resonance imaging

Lapho umbuzo: "computed tomography noma-magnetic resonance imaging - okuyinto engcono" - ke, kufanele kuqashelwe ukuthi magnetic resonance imaging kungabuye wabelwe ukuba bonke abantu. Izimo ngokuphelele le ndlela ukuxilongwa zihlanganisa:

• khona kumadivayisi angewona esikhiphekayo ngogesi;
• khona emzimbeni zemizimba metallic angaphandle;
• khona aneurysms intracranial, klipirovannyh impahla ferromagnetic;
• khona Tattoos on umzimba ngokuqukethwe metallic compounds.

Izimo Isihlobo yilezi:

• sokukhulelwa ekuseni;
• claustrophobia;
• ubuhlungu obukhulu ukuthi ayikuvumeli ukubamba namanje phakathi nesifundo;
• Ukuziphatha ngendlela engafanelanga ngenxa yezidakamizwa noma utshwala;
• isidingo ukuqapha izimpawu ezibalulekile.

Ukuqokwa CT nama-MRI: izibonelo

Kulezi zindlela ukuxilongwa iyona ulwazi kakhulu? Ekuphenduleni lo mbuzo, ngeke akwenze ngaphandle izibonelo. Singacabanga luhlolo nezinso. Ngekhompyutha tomography noma i-MRI? Kuyini kangcono izinso? Lapho kuvela izinkinga ukuvuvukala acute, odokotela linqume ultrasound. Le ndlela eyinhloko zokuxilonga ukuhlola Ubukhulu izinso parenchyma isimo isakhiwo amafutha perirenal. Ukuze ukuhlola nokudlanga nezinguquko sokuvuvukala ngokuningiliziwe babelwe tomography ngekhompyutha.

Uma ngesikhathi ultrasound wembula okuqinile simila kumiswa noma eziyinkimbinkimbi, incazelo siqhutshwa Ngokuphambene CT ukucacisa uphethwe (umehluko ejenti kakhulu kwandisa ulwazi okuqukethwe). Lapho imiphumela ecacile ukukhombisa-magnetic resonance imaging.

Isibonelo esilandelayo - Ukuhlolwa womuntu esolwa unhlangothi ischemic. Ngekhompyutha tomography noma i-MRI? Yini kungcono ubuchopho, ukuhlola isimo yayo ngokuthi isifo? computed tomography wenziwa ngosuku lokuqala. It ikuvumela ukuba ngakususi haemorrhage. Kodwa ngosizo MRI lokhu kungenziwa. Magnetic resonance imaging kuyinto kakhulu kuphela subacute (3-14 ngosuku) futhi ezingalapheki (izinsuku ezingaphezu kwezingu-14) izigaba.

Ngakho, umuntu angekhe atjho bonyana ngiziphi izindlela ukuxilongwa iyona ulwazi kakhulu. tomography ngekhompyutha noma-magnetic resonance imaging - ikuphi okungcono yomgogodla, izinso, ubuchopho nezinye izitho zangaphakathi? Impendulo yalo mbuzo nodokotela njalo endabeni ethile. Futhi computed tomography, futhi-magnetic resonance imaging - indlela ezimbili ulwazi. Kumelwe ukhethe phakathi kwabo njalo ekwenzeni onguchwepheshe, unikezwa isithombe yomtholampilo, isimo umuntu ogulayo, khona isifo.
