Lub plawv CT scan

Kev suav tomography (CT) thaij duab ntawm lub plawv yog ib txoj hauv kev uas siv xoo hluav taws xob los tsim cov duab ntxaws ntawm lub plawv thiab cov hlab ntsha.

• Qhov kev sim no hu ua kev ntsuas ntshav ntawm cov ntshav calcium thaum nws ua los saib seb koj puas muaj cov calcium nyob hauv koj cov hlab ntsha cov ntshav.
• Nws hu ua CT angiography yog tias nws ua rau saib cov hlab ntsha uas nqa ntshav tuaj rau koj lub plawv. Qhov ntsuas no ntsuas tau yog tias muaj qhov nqaim lossis txhaws hauv cov hlab ntsha.
• Qee qhov kev sim ua rau kev soj ntsuam nrog kev soj ntsuam ntawm cov aorta lossis pulmonary cov hlab ntsha mus nrhiav teeb meem nrog cov qauv ntawd.

Koj yuav raug hais kom pw ntawm lub rooj nqaim uas txav mus rau hauv nruab nrab ntawm CT scanner.

• Koj yuav pw rau koj sab nraub qaum nrog koj lub taub hau thiab taw sab nraum lub scanner ntawm ob sab.
• Cov kab xaim me me, hu ua cov electrodes tau muab tso rau hauv koj lub hauv siab thiab txuas nrog lub tshuab uas sau koj lub plawv ua haujlwm hluav taws xob. Koj yuav muab tshuaj rau kom koj lub plawv dhia qeeb.
• Thaum koj 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 khaws cia, saib hauv lub ntsuas, lossis luam tawm ntawm zaj duab xis.
• 3D (peb-seem) qauv ntawm lub siab tuaj yeem tsim.

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.

Cov kev kuaj mob tag nrho yuav tsum tsuas yog siv sijhawm 10 feeb.

Qee qhov kev xeem yuav tsum muaj xim zas tshwj xeeb, hu ua sib piv, kom xa mus rau hauv lub cev ua ntej pib xeem. Lub ntsej muag pab tau qee qhov chaw kom pom zoo dua ntawm kev 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.

Ua ntej tau txais qhov sib piv:

• Qhia koj tus kws kho mob paub yog tias koj tau muaj qhov kev tawm tsam tsis zoo lossis ib yam tshuaj twg. Koj yuav tsum tau noj tshuaj ua ntej kev kuaj mob txhawm rau txhawm rau txais cov tshuaj no yam nyab xeeb.
• Qhia rau koj tus kws kho mob txog tag nrho koj cov tshuaj, vim hais tias koj yuav raug hais kom tuav qee yam, xws li tshuaj noj ntshav qab zib metformin (Glucophage), ua ntej sim.
• Qhia rau koj tus kws kho mob paub yog tias koj muaj teeb meem raum. Cov khoom sib txuam yuav ua rau lub raum ua haujlwm tuaj yeem tsis zoo.

Yog tias koj hnyav dua 300 phaus (135 phaus), nrhiav seb lub tshuab CT puas muaj qhov nyhav tshaj. Lub cev nyhav dhau lawm yuav ua rau lub scanner qhov ua haujlwm puas ntsoog.

Koj yuav raug hais kom tshem cov hniav nyiaj hniav kub thiab hnav lub tsho tshaj sab hauv tsev kho mob thaum qhov kev kawm.

Qee tus neeg yuav muaj qhov tsis xis nyob ntawm dag ntawm lub rooj noj mov nyuaj.

Qhov zoo sib cuam muab los ntawm ib qho IV yuav ua rau:

• Zoo me ntsis hlawv
• Nws yog xim hlau saj hauv lub qhov ncauj
• Sov lub cev tawm ntawm lub cev

Cov kev xav zoo li qub thiab feem ntau yuav ploj mus li ntawm ob peb feeb.

CT sai tsim cov ncauj lus kom ntxaws ntawm lub plawv thiab cov hlab ntsha. Qhov ntsuas yuav kuaj pom lossis kuaj:

• Cov quav hniav buildup nyob rau ntawm cov hlab ntshav txhaws txhawm rau txiav txim siab koj qhov kev pheej hmoo ntawm kab mob plawv
• Congenital plawv (mob plawv uas tam sim no thaum yug)
• Teeb meem nrog lub plawv dhia
• Kev txhaws ntawm cov hlab ntsha uas muab lub plawv
• Cov nqaij hlav lossis cov tawv nqaij hauv lub plawv
• Tso lub luag haujlwm rau lub siab

Cov txiaj ntsig tau txiav txim siab ib txwm muaj yog tias lub siab thiab cov hlab ntsha tau raug tshuaj xyuas yog qhov qub hauv lub cev.

Koj qhov "qhab nias calcium" yog ua raws li cov calcium uas nyob hauv cov hlab ntsha hauv koj lub plawv.

• Qhov ntsuam xyuas yog qhov ib txwm yog (tsis zoo) yog tias koj cov qhab nia calcium yog 0. Qhov no txhais tau tias kev muaj lub siab mob plawv ntau xyoo tom ntej yog qhov tsawg heev.
• Yog tias cov qhab nia calcium ua muaj qis heev, koj yuav tsis zoo siab muaj kab mob txhaws txhaws.

Qhov ntsuas tsis zoo yuav yog vim:

• Aneurysm
• Congenital mob plawv
• Kab mob rau cov hlab ntshav
• Teeb meem lub plawv dhia
• Cov mob o tuaj ncig ntawm lub plawv (mob pericarditis)
• Qhov nqaim ntawm ib lossis ntau cov hlab ntsha hlab ntsha (hlab ntsha o hlab ntsha)
• Cov nqaij hlav los yog lwm qhov hnyav ntawm lub siab lossis thaj chaw ib puag ncig

Yog tias koj cov qhab nia calcium siab heev:

• Nws txhais tau tias koj muaj calcium buildup rau ntawm cov phab ntsa ntawm koj cov hlab ntshav cov ntshav. Qhov no feem ntau yog tus tsos mob atherosclerosis, lossis ua kom tawv nqaij ntawm cov hlab ntsha.
• Koj qhov qhab nia siab dua, qhov teeb meem loj no yuav yog.
• Tham nrog koj tus kws kho mob txog kev hloov pauv hauv koj lub neej koj tuaj yeem ua kom txo qis kev pheej hmoo mob plawv.

Kev phom sij rau CT scans suav nrog:

• Raug rau hluav taws xob
• Kev fab tshuaj rau qhov sib txawv zas

Cov xoo nos xaim yuav ua rau koj raug hluav taws xob ntau dua li 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 yuav tsum tau noj tshuaj steroids (xws li prednisone) lossis antihistamines (xws li diphenhydramine) ua ntej sim. Koj kuj yuav tsum tau noj cov tshuaj histamine blocker (xws li ranitidine).
• Lub raum pab tshem tawm iodine tawm hauv 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.

Tsis tshua muaj, qhov zas xim tuaj yeem ua rau lub neej puas tsuaj uas tsis haum tshuaj hu ua anaphylaxis. Yog tias koj muaj teeb meem ua pa thaum sim, koj yuav tsum ceeb toom rau tus neeg ua haujlwm lub scanner tam sim. Cov tshuaj txig tuaj nrog lub intercom thiab hais lus, yog li tus neeg teb xov tooj tuaj yeem hnov ​​koj txhua lub sijhawm.
