I-Tomography yomgogodla - ukuxilongwa kwezifo zesimanje zesimanje

I-tomography yekhompyutheni iphumelela kakhulu kune-radiography evamile. Ikuvumela ukuba ungaboni nje izinguquko zangaphandle emgodini, kodwa futhi uthole isithombe esiphezulu (uma kunesidingo ngokusungulwa kokuhlukana) izingxenye zekholomu ye-vertebral ngobukhulu obungaphezulu kuka-4-5 mm.

Idatha efanayo ifinyelelwa ngokugcoba umzimba womuntu (indawo edingekayo) ngezinhlayiyana ezivuthayo ezithinta izicubu futhi zithumele izinzwa ezikhona ngokulandelana komunye nomunye wento efundwayo. Uhlelo lwekhompiyutha luqoqa yonke idatha kusuka ezinjenini futhi luwaxhuma ngokucubungula okuyinkimbinkimbi, ekuphumeni okuhlinzeka isithombe esiphelele somonakalo noma isifo ngesimo sezithombe ezizenzekelayo. Ingahle ibonwe ngesilinganiso sesithathu, futhi uma kunesidingo, ochwepheshe bazokwazi ukulinganisa nokwandisa izingxenye ezithile zesitho.

Lolu hlobo lokuhlolwa lukuvumela ukuba ubone ngokucacile okuthe xaxa ezindaweni ezithintekile zamathambo noma i-cartilage, kanye nomonakalo ongase uwenze emgodini womgogodla odlula emgodini ongasemgogodini.

I-Tomography yomgogodla ingenzeka ngokusungulwa kokuhlukile futhi ngaphandle kwayo. Esikhathini sokuqala, isiguli satshelwa ngemibandela eyengeziwe kanye nemiphumela engenzeka yokuletha into emzimbeni (ukuhlanza, ukukhanda ikhanda, ukunganaki emlonyeni). Ngokuvamile, i-tomography, eqinisweni, kanye ne-MRI, yenziwa ngokuphathwa okwengeziwe kwe-anesthetics. Lokhu kwenziwa uma kwenzeka ubuhlungu obukhulu esigulini, ngoba ukungahambi kahle kokuhlolwa yisimo esiyinhloko. Kulokhu, kufanele wanezelwa ukuthi isiguli akufanele sibe nezinto zensimbi, njengokunyakaza, ezingaphambukisa imiphumela yocwaningo.

Inzuzo ye-CT yindlela yokuqokwa kwayo kubantu abanesisindo esiningi, okubandakanya ukuhlolwa okuningiliziwe nokunikeza ukutholakala kwezinkinga ngesikhathi esifanele.

Ngemuva kokuhlolwa, ulwazi lufinyelela kudokotela oya khona, oqaphela ukuthi lesi sifo sinzima kangakanani futhi ebeka ukwelashwa okufanele ngokusho kokuxilongwa. Lapha kufanele kuqaphele ukuthi ngesisekelo se-tomography, umuntu angenza isiphetho mayelana nokusebenza kokungenela okuhlinzekwayo kanye nezinga lokuphuthuma kwalo.

I-tomography ye-spinned computed inikezwa ukucacisa ukuxilongwa ngemva kokujwayela i-radiography esimweni se-hernia ye-intervertebral noma i-tumor esicatshangelwayo kanye ne-metastase yayo, kanye nokuthola ukuxubha kwezimpande zesisindo noma ukuphulwa komzimba. Ucwaningo lungabelwa ukukhomba isigaba sokungenelela okuhlinzekwa ngezifo ezifanayo, futhi ngemuva kokungenelela kokusebenza ukuze uhlole izinga lomsebenzi okwenziwe kanye nezinga lokuphulukisa (kungakhathaliseki ukuthi zonke izidakamizwa nezidumbu ziyasuswa nokuningi).

I-MRI kanye nomehluko wayo kusuka ku-CT

Kunenye indlela efana ne- tomography ehlanganisiwe . Lokhu kuboniswa kwe-resonance magnetic yomgogodla. Emva kwalolu hlelo lwaqala ukusetshenziswa emtholampilo, ukuhlolwa kwe-CT kwakungavamile ukusetshenziselwa ukunciphisa umthamo we-radiation. Idivaysi ye-MRI isekelwe ekuthunjweni kwesignali, esabela ensimini yamagnetic eyenziwe yidivayisi. Zonke izingxenye zomzimba, kuhlanganise namathambo, imisipha, izicubu kanye ne-liquid, zine-athile ehlukile yama-athomu e-hydrogen, wona abe nezici ezihlukile. Zingahlukaniswa ngedivayisi ye-MRI. Ikhompiyutha, lapho ithola idatha efana nayo, iyayichaza futhi idale isithombe esisodwa sesifo.

Inkomba yocwaningo

I-Tomography yomgogodla eyenziwa ukutholakala kwama-intervertebral hernias, ukutholakala kwe-scoliosis noma i-osteoporosis. Lapha ungathola imiphumela mayelana nokukhula kwezicubu zomzimba noma mayelana nokulimala komgogodla (ukuhlukumeza ukucindezeleka, iziphazamiso noma izimo eziphuthumayo kuma-discs ama-vertebral noma ama-cartilages). Ngaphezu kwalokho, i-MRI isetshenziselwa ukutadisha imisipha nemigqa, kanye ne-cartilage nobuchopho. Ukuze ubone izitsha nesibindi ngokuningiliziwe, basebenzisa ukungafani, okufakwa emzimbeni ngekathetha.

I-MRI isetshenziselwa kabanzi kwi-neurology kanye neurosurgery. Imishini enjalo isindisa izimpilo zabantu abaningi, ngoba izinkinga ezibonakala ngesikhathi esifanele, izinyathelo zokuqala zokuphulwa, ukulimala okudala okwaqala ukuzizwa, kungelashwa noma kususwe, futhi lokhu kukhulisa kakhulu ukuphila komuntu.

Izifundo ezinjenge-tomography yomgogodla ne-MRI, khetha udokotela. Nguye owenza isiphetho mayelana nokuphumelela kokufeza lezi zinhlolovo, futhi anqume ukuthi yiziphi ezimbili ezifanele kakhulu isiguli.
