Lub taub hau CT scan
Ib lub taub hau xam tomography (CT) scan siv ntau xoo hluav taws xob los tsim duab ntawm lub taub hau, suav nrog txha taub hau, lub hlwb, lub qhov muag thiab lub qhov ntswg.
Lub taub hau CT tiav hauv tsev kho mob lossis chaw ntsuas hluav taws xob.
Koj pw ntawm qhov rooj nqaim uas nkag mus rau hauv nruab nrab ntawm lub CT scanner.
Thaum nyob sab hauv lub scanner, lub tshuab xoo hluav taws xob tau tig ib ncig ntawm koj.
Lub koos pis tawj tsim cov duab cais ntawm thaj tsam ntawm lub cev, hu ua cov hlais. Cov duab no tuaj yeem yog:
- Khaws cia
- Saib ntawm ib saib
- Rua rau ib disc
Cov peb-seem qauv ntawm cov cheeb tsam lub taub hau tuaj yeem tsim los ntawm kev txiav cov nqov ua ke.
Koj yuav tsum tseem nyob rau qhov kev kuaj mob, vim tias kev txav ua rau cov duab tsis meej. Tej zaum yuav hais kom koj tuav koj cov pa kom txog lub sijhawm luv.
Kev kuaj mob tiav tas feem ntau tsuas siv sijhawm 30 feeb mus rau ob peb feeb xwb.
Qee qhov ntsuas CT yuav tsum tau zas xim tshwj xeeb, hu ua cov khoom sib thooj. Nws yog xa mus rau hauv lub cev ua ntej pib ntsuas pib. Lub ntsej muag pab tau qee qhov chaw qhia tau zoo dua ntawm xoo hluav taws xob.
- Qhov zoo sib txawv tuaj yeem muab los ntawm txoj hlab ntshav (IV) hauv koj txhais tes lossis sab caj npab. Yog tias siv tshuaj sib txawv, koj yuav raug hais kom tsis txhob noj lossis haus dab tsi rau 4 rau 6 teev ua ntej ntsuas.
- Qhia rau koj tus kws kho mob paub yog tias koj muaj qhov tsis haum tshuaj dua. Koj yuav tsum tau noj tshuaj ua ntej kev kuaj mob txhawm rau txhawm rau txais kev nyab xeeb nws.
- Ua ntej tau txais qhov tsis sib xws, qhia rau koj tus kws khomob yog tias koj noj tshuaj ntshav qab zib metformin (Glucophage). Koj yuav tsum tau txais kev ceev faj ntxiv. Thiab qhia rau koj tus kws kho mob paub yog tias koj muaj raum lub raum tsis ua haujlwm vim qhov IV sib txawv tuaj yeem ua kom muaj teebmeem no.
Yog tias koj hnyav dua 300 phaus (135 kg), nrhiav seb lub tshuab CT ua puas muaj qhov hnyav. Qee lub tshuab ua.
Koj yuav raug hais kom tshem cov hniav nyiaj hniav kub thiab tej zaum yuav xav hnav ib lub tsho tiv no lub tsev kho mob thaum qhov kev kawm.
Qhov xoo hluav taws xob uas ua los ntawm CT scan yog tsis muaj mob. Qee tus neeg yuav muaj qhov tsis xis nyob ntawm dag ntawm lub rooj noj mov nyuaj.
Qhov zoo sib xws cov khoom muab los ntawm txoj hlab ntsha tuaj yeem ua rau:
- Txoj kev xav yaim me ntsis
- Nws yog xim hlau saj hauv lub qhov ncauj
- Sov lub cev tawm ntawm lub cev
Qhov no ib txwm ua thiab feem ntau yuav ploj mus li ntawm ob peb feeb.
Lub taub hau CT scan tau raug pom zoo los pab kuaj mob lossis saib xyuas cov xwm txheej hauv qab no:
- Kev yug los ntawm lub hlwb lossis lub hlwb
- Kab mob hlwb
- Mob hlav
- Ua kua hauv cov pob txha taub hau (hydrocephalus)
- Raug mob (raug mob) rau lub hlwb, lub taub hau lossis ntsej muag
- Mob stroke lossis ntshav tawm hauv lub hlwb
Nws tseem yuav raug ua qhov tshawb xyuas qhov ua rau:
- Txawv lub taub hau loj dua hauv cov menyuam yaus
- Kev hloov pauv ntawm kev xav lossis tus cwj pwm
- Tsaus muag
- Mob taub hau, thaum koj muaj qee yam cim los yog tsos mob
- Hnov tsis hnov lus (hauv qee cov tib neeg)
- Cov tsos mob ntawm kev puas tsuaj rau qee qhov ntawm lub hlwb, xws li teeb meem tsis pom kev, leeg tsis muaj zog, pob thiab txhaws, hnov lus tsis zoo, hais lus nyuaj, lossis teeb meem nqos
Qhov ntsuas tsis zoo yuav yog vim:
- Mob ntshav tsis txaus (arteriovenous malformation)
- Bulging cov hlab ntsha hauv lub hlwb (aneurysm)
- Los ntshav (piv txwv, hematoma los yog los ntshav hauv lub hlwb)
- Mob pob txha
- Hlwb hauv neeg lub hlwb los yog muaj tus kab mob
- Lub hlwb puas vim kev raug mob
- Hlwb daim ntaub o lossis raug mob
- Mob qog lossis lwm qhov kev loj hlob (loj)
- Poob rau lub hlwb cov ntaub so ntswg (cerebral atrophy)
- Hydrocephalus
- Teeb meem nrog lub pob ntseg hnov
- Mob stroke lossis cov ischemic nres (TIA)
Kev phom sij ntawm CT scans suav nrog:
- Raug rau hluav taws xob
- Kev fab tshuaj rau qhov sib txawv zas
- Lub raum puas tsuaj los ntawm qhov xim sib txawv
Cov duab xoo fais fab siv hluav taws xob ntau dua xoo hluav taws xob. Muaj ntau xoo duab hluav taws xob lossis CT scan ntau dhau sijhawm yuav ua rau koj muaj feem mob qog nqaij hlav cancer. Txawm li cas los xij, kev pheej hmoo los ntawm kev tshuaj ntsuam ib qho me me. Koj thiab koj tus kws kho mob yuav tsum luj qhov kev pheej hmoo no tawm tsam cov txiaj ntsig ntawm kev tau txais kev txheeb xyuas tus mob rau qhov teeb meem kev kho mob.
Qee tus neeg siv ua xua rau kev zas xim txawv. Qhia rau koj tus kws kho mob paub yog tias koj tau muaj kev fab tshuaj rau kev zas xim txawv.
- Feem ntau ntawm kev sib xyaw uas tau muab rau hauv txoj hlab ntsha muaj iodine. Yog hais tias ib tus neeg uas muaj kev fab tshuaj iodine tau txais hom tshuaj no txawv, xeev siab lossis ntuav, txham, ua pob khaus, lossis khaus.
- Yog tias koj yuav tsum tau muab cov kev sib thooj no, koj tus kws kho mob yuav muab tshuaj antihistamines rau koj (xws li Benadryl) lossis tshuaj steroids ua ntej kev kuaj mob kom tiv thaiv kev fab tshuaj.
- Lub raum pab tshem tawm iodine tawm ntawm lub cev. Cov neeg muaj kab mob hauv lub raum lossis ntshav qab zib yuav tsum tau haus dej ntxiv tom qab kuaj xyuas los pab yaug iodine tawm ntawm lub cev.
Qee qhov tsis tshua muaj, cov xim zas tuaj yeem ua rau kom muaj kev phom sij txog txoj sia hu ua anaphylaxis. Yog tias koj muaj teeb meem ua pa thaum sim, qhia tus neeg teb xov tooj scanner tam sim ntawd. Cov cav thaij tuaj nrog lub intercom thiab hais lus, yog li qee tus tuaj yeem hnov koj txhua lub sijhawm.
Qhov ntsuas duab CT tuaj yeem txo lossis zam rau qhov kev xav tau ntawm tus txheej txheem ntxeem tau los kuaj xyuas teeb meem hauv pob txha taub hau. Qhov no yog ib qho kev nyab xeeb tshaj plaws los kawm lub taub hau thiab caj dab.
Lwm cov kev kuaj uas yuav ua los siv taub hau CT scan xam yog:
- MRI ntawm lub taub hau
- Positron emission tomography (PET) scan ntawm lub taub hau
Lub Hlwb CT; Cranial CT; CT scan - pob txha taub hau; CT scan - taub hau; Iav scan - orbits; CT scan - kev ua txhaum; Tham tomography - cranial; CAT scan - lub hlwb
- Lub taub hau CT
