CT (computed tomography) scan yog ib qho kev kuaj pom uas pab cov kws kho mob kuaj pom tus kab mob thiab raug mob. Nws siv cov X-rays thiab khoos phis tawj los tsim cov duab ntxaws ntxaws ntawm cov pob txha thiab cov nqaij mos. CT scans tsis mob thiab tsis cuam tshuam. Koj tuaj yeem mus rau hauv tsev kho mob lossis chaw kuaj duab rau CT scan vim qee yam mob. Kab lus no yuav qhia koj txog CT scanning kom meej.
CT scan yog dab tsi?
Ib qho CT (computed tomography) scan yog ib qho kev kuaj pom. Ib yam li X-ray, nws tuaj yeem qhia cov qauv hauv koj lub cev. Tab sis es tsis txhob tsim cov duab 2D tiaj tus, CT scans coj ntau ntau rau ntau pua cov duab ntawm lub cev. Yuav kom tau txais cov duab no, CT yuav coj X-rays thaum nws tig mus ncig koj.
Cov kws kho mob siv CT scans kom pom qhov X-rays tsis tuaj yeem pom. Piv txwv li, lub cev qauv sib tshooj ntawm cov qauv X-rays, thiab ntau yam tsis pom. CT qhia cov ncauj lus kom ntxaws txog txhua lub cev kom pom tseeb dua, pom meej dua.
Lwm lub sij hawm rau CT scan yog CAT scan. CT stands rau "computed Tomography," thaum CAT stands rau "computed axial tomography." Tab sis ob nqe lus piav qhia tib yam kev sim duab.
CT scan qhia dab tsi?
CT scan coj cov duab ntawm koj:
Cov pob txha.
Cov leeg.
Lub cev.
Cov hlab ntsha.
CT scans pom dab tsi?
CT scans pab cov kws kho mob tshawb xyuas ntau yam kev raug mob thiab kab mob, suav nrog:
Qee hom mob qog noj ntshav thiab benign (noncancerous) qog.
Fractures (pob txha tawg).
Mob plawv.
Ntshav txhaws.
Cov kab mob hauv plab (appendicitis, diverticulitis, blockages, Crohn's disease).
Lub raum pob zeb.
Mob hlwb.
Kev raug mob txha caj qaum.
Internal los ntshav.
Kev npaj rau ct scan
Nov yog qee cov lus qhia dav dav:
l Npaj kom txog thaum ntxov. Koj tus kws kho mob yuav qhia rau koj thaum twg koj yuav tsum teem sijhawm teem sijhawm.
l Tsis txhob noj plaub teev ua ntej koj CT scan.
l Haus dej ntshiab (xws li dej, kua txiv, lossis tshuaj yej) hauv ob teev ua ntej koj teem caij.
l Hnav khaub ncaws zoo thiab tshem tawm cov hniav nyiaj hniav kub lossis khaub ncaws (nco ntsoov tias txhua yam uas muaj hlau tsis raug tso cai!). Tus nais maum yuav muab ib lub tsho hauv tsev kho mob.
Koj tus kws kho mob tuaj yeem siv cov khoom sib txawv los qhia txog qee qhov chaw ntawm koj lub cev ntawm qhov scan. Rau qhov sib piv CT scan, tus neeg teb xov tooj yuav tso ib qho IV (txiav catheter) thiab txhaj qhov sib piv nruab nrab (lossis xim) rau hauv koj cov leeg. Lawv kuj tseem tuaj yeem muab cov khoom haus rau koj (xws li barium nqos) los ua rau koj cov hnyuv. Ob leeg tuaj yeem txhim kho kev pom ntawm cov ntaub so ntswg, kab mob lossis cov hlab ntsha thiab pab cov kws kho mob kuaj pom ntau yam mob. Thaum koj tso zis, cov khoom sib txawv hauv cov hlab ntsha feem ntau yog ntws tawm ntawm koj lub cev hauv 24 teev.
Dab tsi hauv qab no yog qee cov lus qhia ntxiv txog kev npaj rau CT sib piv scan:
Kev kuaj ntshav: Tej zaum koj yuav xav tau kev kuaj ntshav ua ntej koj teem sijhawm CT scan. Qhov no yuav pab koj tus kws kho mob kom ntseeg tau tias qhov sib piv nruab nrab muaj kev nyab xeeb siv.
Kev txwv kev noj haus: Koj yuav tsum tau saib xyuas koj cov zaub mov plaub teev ua ntej koj CT scan. Kev haus cov kua ntshiab nkaus xwb tuaj yeem pab tiv thaiv xeev siab thaum tau txais cov xov xwm sib txawv. Koj tuaj yeem muaj kua zaub, tshuaj yej lossis kas fes dub, kua txiv lim dej, gelatin, thiab cov dej qab zib ntshiab.
Cov tshuaj ua xua: Yog tias koj ua xua rau qhov sib piv nruab nrab siv rau CT (uas muaj iodine), koj yuav tsum tau noj cov tshuaj steroids thiab tshuaj tiv thaiv kab mob hmo ntuj ua ntej thiab sawv ntxov ntawm kev phais. Nco ntsoov xyuas nrog koj tus kws kho mob thiab nug lawv kom xaj cov tshuaj no rau koj yog tias xav tau. (Cov tshuaj sib piv rau MRI thiab CT yog qhov sib txawv. Kev ua xua rau ib tus neeg sawv cev sib txawv tsis txhais tau tias koj tsis haum rau lwm tus.)
Kev Npaj Tshuaj: Qhov ncauj qhov sib piv cov xov xwm daws teeb meem yuav tsum tau noj raws nraim li qhia.
Cov haujlwm tshwj xeeb hauv CT scan
Thaum kuaj, tus neeg mob feem ntau yuav pw ntawm lawv nraub qaum ntawm lub rooj (xws li lub txaj). Yog hais tias tus neeg mob qhov kev kuaj yuav tsum tau, tus kws kho mob yuav txhaj tshuaj sib txawv ntawm cov tshuaj intravenously (rau hauv tus neeg mob cov leeg). Cov xim tuaj yeem ua rau cov neeg mob hnov ntxhiab lossis muaj xim hlau saj hauv lawv lub qhov ncauj.
Thaum lub scan pib:
Lub txaj maj mam txav mus rau hauv lub scanner. Nyob rau ntawm lub sijhawm no, cov duab donut yuav tsum nyob twj ywm li qhov ua tau, vim tias kev txav yuav plam daim duab.
Cov txiv hmab txiv ntoo zoo li no kuj yuav raug nug kom tuav lawv cov pa ib ntus, feem ntau tsawg dua 15 mus rau 20 vib nas this.
Lub scanner siv daim duab donut-shaped ntawm thaj chaw uas cov kws kho mob xav pom. Tsis zoo li MRI scans (magnetic resonance imaging scans), CT scans nyob twj ywm.
Tom qab kev soj ntsuam tiav lawm, lub workbench txav rov qab rau sab nraum lub scanner.
CT scan lub sijhawm
Ib qho CT scan feem ntau yuav siv li ib teev. Feem ntau lub sij hawm yog kev npaj. Lub scan nws tus kheej siv sijhawm tsawg dua 10 lossis 15 feeb. Koj tuaj yeem rov ua haujlwm li qub tom qab koj tus kws kho mob pom zoo - feem ntau tom qab lawv tau ua tiav qhov scan thiab ua kom cov duab zoo.
CT scan tshwm sim
CT scan nws tus kheej feem ntau tsis ua rau muaj kev phiv. Tab sis qee tus neeg muaj kev phiv me me los ntawm tus neeg sawv cev sib txawv. Cov kev mob tshwm sim no tuaj yeem suav nrog xeev siab thiab ntuav, mob taub hau, thiab kiv taub hau.

Hais txog LnkMed:
Txij li thaum nws tsim,LnkMedtau tsom mus rau thaj chaw ntawmhigh-pressure contrast tus neeg sawv cev injectors. LnkMed pawg engineering yog coj los ntawm Ph.D. nrog ntau tshaj kaum xyoo ntawm kev paub thiab tau koom nrog kev tshawb fawb thiab kev loj hlob. Nyob rau hauv nws cov kev taw qhia, lubCT ib lub taub hau injector, CT ob lub taub hau injector, MRI contrast tus neeg sawv cev injector, thiabAngiography high-pressure contrast agent injectoryog tsim los nrog cov yam ntxwv no: lub cev muaj zog thiab compact, yooj yim thiab ntse ua haujlwm interface, ua tiav kev ua haujlwm, muaj kev nyab xeeb siab, thiab tsim qauv ruaj khov. Peb kuj tseem tuaj yeem muab cov koob txhaj tshuaj thiab cov raj uas sib haum nrog cov npe nrov ntawm CT, MRI, DSA txhaj tshuaj Nrog lawv tus cwj pwm ncaj ncees thiab lub zog ua haujlwm, txhua tus neeg ua haujlwm ntawm LnkMed thov caw koj tuaj thiab tshawb nrhiav ntau lub lag luam ua ke.
