Chifuwa CT

Kujambula pachifuwa cha CT (computed tomography) ndi njira yojambulira yomwe imagwiritsa ntchito ma x-ray kupanga zithunzi zamagulu ophatikizira pachifuwa ndi m'mimba.

Kuyesaku kwachitika motere:

• Muyenera kuti mudzapemphedwa kuti musinthe chovala chaku chipatala.
• Mumagona pa tebulo laling'ono lomwe limalowa pakati pa sikani. Mukakhala mkati mwa sikani, makina a x-ray azungulira mozungulira.
• Muyenera kukhala bata pakamayesa, chifukwa mayendedwe amayambitsa zithunzi zolakwika. Mutha kuuzidwa kuti musunge mpweya wanu kwakanthawi kochepa.

Kujambula kwathunthu kumatenga masekondi 30 mpaka mphindi zochepa.

Zithunzi zina za CT zimafuna utoto wapadera, wotchedwa kusiyana, kuti uperekedwe m'thupi mayeso asanayambe. Kusiyanitsa kumawunikira madera ena mkati mwa thupi ndikupanga chithunzi chowonekera. Ngati wothandizira wanu apempha CT scan ndi kusiyanitsa kwamitsempha, mudzakupatsani kudzera mu mtsempha (IV) m'manja mwanu kapena m'manja. Kuyezetsa magazi kuyeza ntchito yanu ya impso kumatha kuchitika musanayezedwe. Kuyesaku ndikuwonetsetsa kuti impso zanu zili ndi thanzi lokwanira kusiyanitsa.

Mutha kupatsidwa mankhwala okuthandizani kupumula poyesa.

Anthu ena ali ndi vuto losagwirizana ndi IV ndipo angafunike kumwa mankhwala asanayesedwe kuti alandire mankhwalawa.

Ngati kusiyanitsa kumagwiritsidwa ntchito, mungapemphedwenso kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 musanayesedwe.

Ngati mukulemera makilogalamu opitilira 300 (135 kilograms), uzani wothandizira zaumoyo wanu kuti alumikizane ndi woyeserera asanayese. Makina a CT ali ndi malire olemera kwambiri a mapaundi 300 mpaka 400 (100 mpaka 200 kilogalamu). Makina atsopano amatha kukhala ndi mapaundi 600 (makilogalamu 270). Chifukwa ndizovuta kuti ma x-ray adutse pazitsulo, mudzafunsidwa kuti muchotse zodzikongoletsera.

Anthu ena atha kukhala osasangalala pogona patebulo lolimba.

Kusiyanitsa komwe kumachitika kudzera mu IV kumatha kuyambitsa kutentha pang'ono, kulawa kwazitsulo mkamwa, ndi kutentha thupi. Zomverera izi ndi zachilendo ndipo nthawi zambiri zimatha patangopita masekondi ochepa.

Palibe nthawi yochira, pokhapokha mutapatsidwa mankhwala oti mupumule. Mukatha kujambulidwa ndi CT, mutha kubwereranso ku zomwe mumadya, zochita zanu, komanso mankhwala anu.

CT imapanga zithunzi mwatsatanetsatane za thupi. Mayesowa atha kugwiritsidwa ntchito kuti muwone bwino zomwe zili mkati mwa chifuwa. CT scan ndi imodzi mwanjira zabwino kwambiri zowonera minofu yofewa monga mtima ndi mapapo.

Chifuwa cha CT chitha kuchitika:

• Pambuyo povulala pachifuwa
• Mukakayikira chotupa kapena misa (kuchuluka kwa maselo), kuphatikiza phokoso lokhalokha la m'mapapo lomwe limapezeka pachifuwa x-ray
• Kuti mudziwe kukula, mawonekedwe, ndi momwe ziwalo zilili pachifuwa ndi pamimba chapamwamba
• Kuyang'ana magulu otulutsa magazi kapena am'mapapo kapena madera ena
• Kuyang'ana matenda kapena kutupa pachifuwa
• Kuti muyang'ane magazi aundana m'mapapu
• Kuyang'ana zipsera m'mapapu
  

Thoracic CT imatha kuwonetsa zovuta zambiri pamtima, m'mapapo, mediastinum, kapena pachifuwa, kuphatikiza:

• Kugwetsa pakhoma, kukulira kapena kubaluni kosazolowereka, kapena kuchepa kwa mtsempha waukulu womwe umatulutsa magazi kuchokera mumtima (aorta)
• Zosintha zina zachilendo m'mitsempha yayikulu m'mapapu kapena pachifuwa
• Kupanga magazi kapena madzimadzi mozungulira mtima
• Khansa ya m'mapapo kapena khansa yomwe yafalikira m'mapapu kuchokera kwina kulikonse mthupi
• Kutolera kwamadzimadzi mozungulira mapapo (pleural effusion)
• Kuwonongeka kwa, ndikukulitsa njira yayikulu yamapapu (bronchiectasis)
• Mafupa okulirapo
• Matenda am'mapapo momwe m'mapapo mwanga mumatupa kenako nkuwonongeka.
• Chibayo
• Khansa ya Esophageal
• Lymphoma pachifuwa
• Zotupa, zopindika, kapena zotupa pachifuwa

Kujambula kwa CT ndi ma x-ray ena amayang'aniridwa mosamala ndikuwongolera kuti awonetsetse kuti agwiritsa ntchito radiation yochepa. Makina a CT amagwiritsa ntchito ma radiation ochepa, omwe amatha kuyambitsa khansa ndi zolakwika zina. Komabe, chiwopsezo chojambulidwa kamodzi ndichaching'ono. Chiwopsezo chikuwonjezeka pomwe maphunziro ena ambiri amachitika.

Mtundu wofala kwambiri womwe umaperekedwa mumtsinje uli ndi ayodini. Ngati munthu yemwe ali ndi vuto la ayodini wapatsidwa kusiyana kotere, nseru, kuyetsemula, kusanza, kuyabwa, kapena ming'oma kumatha kuchitika. Nthawi zambiri, utoto umatha kuyambitsa matenda omwe amatchedwa anaphylaxis. Ngati mukuvutika kupuma panthawi yoyesayo, muyenera kudziwitsa operekera makinawo nthawi yomweyo. Zitsulo zofufuzira zidazo zimabwera ndi intakomu ndiponso masipika, kuti munthu azimvanso nthawi zonse.

Kwa anthu omwe ali ndi vuto la impso, utoto ungakhale ndi zotsatirapo zoipa pa impso. Muzochitika izi, pakhoza kuchitapo kanthu kuti utoto wosiyanitsa uzikhala wotetezeka kugwiritsa ntchito.

Nthawi zina, CT scan ikhoza kuchitikabe ngati maubwino apitilira zoopsa zake. Mwachitsanzo, zitha kukhala zowopsa kusayesedwa ngati omwe amakupatsani akuganiza kuti mwina muli ndi khansa.
