Kev thaij duab CT (computed tomography) yog kev kuaj duab uas pab cov kws kho mob nrhiav pom kab mob thiab raug mob. Nws siv ntau yam duab X-rays thiab khoos phis tawj los tsim cov duab ntxaws ntxaws ntawm pob txha thiab cov nqaij mos. Kev thaij duab CT tsis mob thiab tsis ua rau mob. Koj tuaj yeem mus rau tsev kho mob lossis chaw thaij duab rau kev thaij duab CT vim muaj qee yam kab mob. Tsab xov xwm no yuav qhia koj txog kev thaij duab CT kom ntxaws.
Kev luam theej duab CT yog dab tsi?
Kev thaij duab CT (computed tomography) yog kev kuaj duab. 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 siv kaum ob mus rau pua pua daim duab ntawm lub cev. Txhawm rau kom tau txais cov duab no, CT yuav thaij duab X-rays thaum nws tig ib puag ncig koj.
Cov kws kho mob siv CT scans los saib seb cov duab X-ray ib txwm muaj tsis tuaj yeem pom dab tsi. Piv txwv li, cov qauv ntawm lub cev sib tshooj ntawm cov duab X-ray ib txwm muaj, thiab ntau yam tsis pom. CT qhia cov ntaub ntawv qhia txog txhua lub cev kom pom tseeb dua thiab meej dua.
Lwm lo lus rau CT scan yog CAT scan. CT sawv cev rau "computed Tomography," thaum CAT sawv cev rau "computed axial tomography." Tab sis ob lo lus no piav qhia txog tib qho kev kuaj duab.
Kev luam theej duab CT qhia dab tsi?
Ib daim CT scan yuav thaij duab koj cov:
Cov pob txha.
Cov leeg nqaij.
Cov kabmob.
Cov hlab ntsha.
Cov duab CT scans tuaj yeem pom dab tsi?
Cov kev luam theej CT pab cov kws kho mob nrhiav tau ntau yam kev raug mob thiab kab mob, suav nrog:
Qee hom mob qog noj ntshav thiab cov qog nqaij hlav benign (tsis yog mob qog noj ntshav).
Pob txha tawg (pob txha tawg).
Kab mob plawv.
Cov ntshav txhaws.
Cov kab mob ntawm txoj hnyuv (mob appendicitis, diverticulitis, blockages, Crohn's disease).
Pob zeb hauv lub raum.
Kev raug mob hlwb.
Kev raug mob ntawm cov hlab ntsha qaum.
Kev los ntshav sab hauv.
Kev npaj rau kev kuaj CT
Nov yog qee cov lus qhia dav dav:
Npaj tuaj txog ntxov. Koj tus kws kho mob yuav qhia koj thaum twg koj yuav tsum mus raws li koj lub sijhawm teem tseg.
Tsis txhob noj mov plaub teev ua ntej koj kuaj CT.
Haus tsuas yog cov dej ntshiab (xws li dej, kua txiv hmab txiv ntoo, lossis tshuaj yej) ob teev ua ntej koj lub sijhawm teem tseg.
Hnav khaub ncaws xis nyob thiab tshem tawm cov hniav nyiaj hniav kub lossis khaub ncaws uas ua los ntawm hlau (nco ntsoov tias tsis pub siv txhua yam uas muaj hlau!). Tus kws tu mob yuav muab ib lub tsho hauv tsev kho mob rau koj.
Koj tus kws kho mob yuav siv cov khoom siv sib piv los qhia txog qee qhov chaw ntawm koj lub cev ntawm daim duab luam theej. Rau kev luam theej duab CT sib piv, tus neeg ua haujlwm yuav muab ib txoj hlab ntshav (catheter) thiab txhaj ib qho khoom siv sib piv (lossis xim zas) rau hauv koj cov leeg ntshav. Lawv kuj tseem yuav muab ib yam khoom haus tau rau koj (xws li barium nqos) los nthuav koj cov hnyuv. Ob qho tib si tuaj yeem txhim kho qhov pom ntawm cov nqaij tshwj xeeb, cov kabmob lossis cov hlab ntsha thiab pab cov kws kho mob kuaj mob ntau yam mob. Thaum koj tso zis, cov khoom siv sib piv hauv cov hlab ntshav feem ntau yuav raug ntxuav tawm ntawm koj lub cev hauv 24 teev.
Nov yog qee cov lus qhia ntxiv rau kev npaj rau CT scan contrast:
Kuaj ntshav: Tej zaum koj yuav tsum tau kuaj ntshav ua ntej koj teem sijhawm CT scan. Qhov no yuav pab koj tus kws kho mob xyuas kom meej tias cov tshuaj contrast siv tau zoo.
Kev Txwv Kev Noj Haus: Koj yuav tsum tau saib xyuas koj cov zaub mov plaub teev ua ntej koj thaij CT scan. Haus dej ntshiab xwb tuaj yeem pab tiv thaiv kev xeev siab thaum noj cov tshuaj contrast media. Koj tuaj yeem haus kua zaub, tshuaj yej lossis kas fes dub, kua txiv lim, gelatin dawb, thiab dej qab zib ntshiab.
Cov Tshuaj Kho Mob Ua Xua: Yog tias koj ua xua rau cov tshuaj sib piv uas siv rau CT (uas muaj iodine), koj yuav tsum tau noj cov tshuaj steroids thiab cov tshuaj antihistamines hmo ua ntej thiab thaum sawv ntxov ntawm kev phais. Nco ntsoov nrog koj tus kws kho mob tham thiab hais kom lawv xaj cov tshuaj no rau koj yog tias xav tau. (Cov tshuaj sib piv rau MRI thiab CT txawv. Kev ua xua rau ib qho tshuaj sib piv tsis tau txhais hais tias koj ua xua rau lwm qhov.)
Npaj Cov Tshuaj: Cov tshuaj sib xyaw ua ke yuav tsum noj raws li cov lus qhia.
Cov haujlwm tshwj xeeb hauv CT scan
Thaum lub sijhawm kuaj mob, tus neeg mob feem ntau yuav pw ntxeev tiaj rau ntawm lub rooj (xws li lub txaj). Yog tias qhov kev kuaj mob ntawm tus neeg mob xav tau, tus kws kho mob yuav txhaj tshuaj xim sib txawv rau hauv cov hlab ntsha (rau hauv tus neeg mob cov hlab ntsha). Cov xim no tuaj yeem ua rau cov neeg mob hnov mob liab lossis muaj saj hlau hauv lawv lub qhov ncauj.
Thaum lub scan pib:
Lub txaj maj mam txav mus rau hauv lub tshuab ntsuas. Thaum lub sijhawm no, lub duab donut yuav tsum nyob twj ywm li sai tau, vim tias kev txav mus los yuav ua rau daim duab tsis meej.
Cov uas zoo li lub ncuav mog kuj yuav raug hais kom tuav lawv txoj pa rau lub sijhawm luv luv, feem ntau tsawg dua 15 txog 20 vib nas this.
Lub tshuab ntsuas duab thaij ib daim duab zoo li lub ncuav mog qab zib ntawm thaj chaw uas cov kws kho mob xav pom. Tsis zoo li MRI scans (magnetic resonance imaging scans), CT scans tsis muaj suab nrov.
Tom qab kev tshuaj xyuas tiav lawm, lub rooj ua haujlwm yuav txav rov qab mus rau sab nraud ntawm lub scanner.
Lub sijhawm ntawm kev luam theej duab CT
Feem ntau, kev thaij duab CT yuav siv sijhawm li ib teev. Feem ntau yog kev npaj. Kev thaij duab nws tus kheej siv sijhawm tsawg dua 10 lossis 15 feeb. Koj tuaj yeem rov ua cov haujlwm ib txwm tom qab koj tus kws kho mob pom zoo - feem ntau yog tom qab lawv ua tiav kev thaij duab thiab xyuas kom meej tias daim duab zoo.
Cov kev mob tshwm sim ntawm CT scan
Feem ntau, daim duab CT scan nws tus kheej tsis ua rau muaj kev phiv. Tab sis qee tus neeg muaj kev phiv me me los ntawm cov tshuaj sib piv. Cov kev phiv no yuav suav nrog xeev siab thiab ntuav, mob taub hau, thiab kiv taub hau.
