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

Qhov sib piv tau muab los ntawm ib qho IV yuav ua rau muaj kev hnov ​​mob me ntsis, nws yog xim hlau hauv lub qhov ncauj, thiab sov lub cev. Cov kev xav no yeej ib txwm muaj. Lawv yuav ploj mus li ntawm ob peb feeb.

CT sai tsim cov ncauj lus kom ntxaws ntawm lub cev, suav nrog caj npab. Qhov ntsuas yuav tuaj yeem pab kuaj lossis kuaj:

• Qog mob los yog kis
• Qhov ua kom mob mob lossis lwm yam teeb meem hauv lub dab teg, ntawm lub xub pwg lossis lub luj tshib (feem ntau yog thaum MRI ua tsis tau)
• Ib tug 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 tsis muaj teeb meem pom hauv cov duab.

Qhov ntsuas tsis zoo yuav yog vim:

• Kev hloov pauv hloov vim lub hnub nyoog
• Qaug (sau ntawm pus)
• Cov ntshav txhaws ntawm caj npab (tob venous thrombosis)
• Cov pob txha hlav
• Mob Cancer
• Cov pob txha tawg lossis pob txha tawg
• Puas rau tes, dab teg, lossis lauj tshib pob qij txha
• Cuag
• Kho cov teeb meem lossis kev loj hlob ntawm caws pliav tom qab kev phais mob

Kev phom sij ntawm 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 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.
