Ceg ceg scan

Kev suav tomography (CT) thaij duab ntawm txhais ceg ua duab sib tshooj ntawm ob txhais ceg. Nws siv xoo hluav taws xob los tsim cov duab.

Koj yuav tau pw ntawm lub rooj nqaim uas nkag mus rau hauv nruab nrab ntawm lub CT scanner.

Thaum koj nyob sab hauv lub scanner, lub tshuab xoo hluav taws xob tau tig ib ncig ntawm koj. (Niaj hnub nimno "muab kauv" scanner tuaj yeem ua qhov kev soj ntsuam yam tsis txwv.)

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. Peb-seem (3D) cov qauv ntawm txhais ceg tuaj yeem tsim los ntawm kev ntxiv cov hlais ua ke.

Koj yuav tau dag thaum lub sijhawm kuaj mob. Zog tuaj yeem ua rau cov duab fim. Tej zaum koj yuav tau tuav koj lub pa kom txog ncua sijhawm luv.

Kev thaij duab yuav tsum siv sijhawm ntev li 10 mus rau 15 feeb xwb.

Qee qhov kev kuaj mob siv cov zas xim tshwj xeeb, hu ua sib piv, uas tau muab tso rau hauv koj 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.
• 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 kom zam dhau cov teeb meem no.
• Ua ntej muaj qhov sib txawv, qhia rau koj tus kws kho mob yog tias koj noj tshuaj ntshav qab zib metformin (Glucophage). Koj yuav tsum tau rhais kauj ruam ntxiv ua ntej kev sim yog tias koj noj cov tshuaj no.

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

Koj yuav hnav ib lub tsho tshaj sab hauv tsev kho mob thaum kawm ntawv. Koj yuav tsum tau hle tag nrho cov hniav nyiaj hniav kub.

Qee tus neeg yuav tsis xis nyob dag ntawm lub rooj nyuaj.

Qhov sib piv tau muab los ntawm ib qho IV tuaj yeem ua rau me ntsis zoo nkaus li hnov ​​qab, lub suab nrov hauv lub qhov ncauj, thiab sov lub cev. Cov kev xav zoo li qub thiab ploj mus hauv ob peb feeb.

CT scan ua cov ncauj lus kom ntxaws ntawm lub cev tau nrawm heev. Qhov ntsuas yuav pab xyuas:

• Qog mob los yog kis
• Ib qhov loj uas tau hnov ​​thaum kuaj lub cev
• Qhov ua kom mob lossis lwm yam teeb meem hauv ko taw, pob taws, lossis pob qij txha (feem ntau yog thaum MRI ua tsis tau)
• Ib tug pob txha tawg
• Tus qauv ntawm cov pob txha tawg
• Masses thiab qog, suav nrog mob cancer
• Kho teeb meem lossis caws pliav tom qab phais tas

Kev thaij duab CT kuj tseem siv tau los coj tus kws phais neeg mus rau thaj chaw raug mob thaum siv lub tshuab kuaj ntshav.

Cov txiaj ntsig tau txiav txim siab ib txwm muaj yog tias txhais ceg tau tshuaj xyuas zoo nkaus li OK.

Qhov ntsuas tsis zoo yuav yog vim:

• Kev hloov pauv hloov vim lub hnub nyoog
• Qog lossis kis tau tus mob
• Cov ntshav txhaws hauv ceg (tob venous thrombosis)
• Cov pob txha tawg lossis pob txha tawg
• Mob Cancer
• Puas tsuaj rau hauv caug, txhais taw, lossis pob taws pob qij txha
• Cov pob txha tsis muaj pob txha mos
• Kho cov teeb meem lossis kev loj hlob ntawm caws pliav tom qab kev phais mob

Kev phom sij rau CT scans suav nrog:

• Raug rau hluav taws xob
• Kev fab tshuaj rau qhov sib txawv zas
• Kev xeeb menyuam yog tias ua thaum cev xeeb tub

Kev ntsuas duab CT qhia kom koj raug hluav taws xob ntau dua li xoo hluav taws xob. Muaj ntau xoo hluav taws xob lossis xoo fais fab ntev dhau ntawm lub sijhawm yuav ua rau koj muaj feem mob qog nqaij hlav cancer, tab sis kev pheej hmoo los ntawm kev kuaj ib qho me me. Tham nrog koj tus kws kho mob txog qhov kev pheej hmoo no tawm tsam cov txiaj ntsig ntawm kev sim.

Qee tus neeg siv ua xua rau kev zas xim txawv. Qhia rau koj tus kws kho mob paub yog tias koj tau muaj hom mob tshwm sim no dua.

• Feem ntau ntawm kev sib xyaw uas tau muab rau hauv txoj hlab ntsha muaj iodine. Tus neeg uas muaj kev fab tshuaj iodine yuav xeev ntuav lossis ntuav, txham, ua pob khaus, lossis khaus los ntawm hom sib txawv no.
• Yog tias koj yuav tsum muaj qhov sib piv ntawm no, koj yuav tau txais tshuaj antihistamines (xws li Benadryl) lossis steroids ua ntej sim.
• 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 ntau ntxiv tom qab kuaj xyuas los pab yaug iodine tawm ntawm lub cev.

Qhov zas xim yuav ua rau lub neej puas tsuaj uas hu ua anaphylaxis. Qhov no tsis tshua muaj. Qhia tus neeg teb xov tooj scanner tam sim ntawd yog tias koj muaj teeb meem ua pa ntawm qhov kev 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.
