Kujambula kwa CT

Makina owerengera a tomography (CT) ndi njira yojambulira yomwe imagwiritsa ntchito ma x-ray kupanga zithunzi zamagawo amthupi.

Mayeso ofanana ndi awa:

• M'mimba ndi m'chiuno CT scan
• Cranial kapena mutu CT scan
• Cervical, thoracic, ndi lumbosacral msana CT scan
• Kujambula kwa CT
• Chifuwa cha CT

Mudzafunsidwa kuti mugone patebulo lochepetsetsa lomwe limalowa pakati pa chojambulira cha CT.

Mukakhala mkati mwa sikani, makina a x-ray azungulira mozungulira. Makina azithunzi amakono amatha kuchita mayeso osayima.

Kakompyuta imapanga zithunzi zosiyana za thupi, zotchedwa magawo. Zithunzi izi zimatha kusungidwa, kuwonedwa pa polojekiti, kapena kukopera ku disk. Mitundu yazithunzi zitatu za thupi imatha kupangidwa ndikulumikiza magawo palimodzi.

Muyenera kukhala chete pakuyesa, chifukwa mayendedwe amabweretsa zithunzi zosawoneka bwino. Mutha kuuzidwa kuti musunge mpweya wanu kwakanthawi kochepa.

Kusintha kwathunthu kumangotenga mphindi zochepa. Makina atsopanowa atha kujambulitsa thupi lanu lonse m'masekondi 30.

Mayeso ena amafunika utoto wapadera, wotchedwa kusiyanasiyana, kuti uperekedwe m'thupi lanu mayeso asanayambe. Kusiyanitsa kumathandizira madera ena kuwonekera bwino pama x-ray.

Lolani wothandizira zaumoyo wanu adziwe ngati mudachitapo kanthu posiyanitsa. Mungafunike kumwa mankhwala musanayezedwe kuti mupewe kuchitapo kanthu.

Kusiyanitsa kungaperekedwe m'njira zingapo, kutengera mtundu wa CT yomwe ikuchitidwa.

• Itha kuperekedwa kudzera mumitsempha (IV) m'manja mwanu kapena m'manja.
• Mutha kumwa kusiyanasiyana musanajambulire. Mukamwa kusiyana kumatengera mtundu wa mayeso omwe akuchitika. Madzi amtunduwu amatha kulawa, ngakhale ena amakomedwa. Kusiyanako kumachoka mthupi lanu kupyola m'mipando yanu.
• Nthawi zambiri, kusiyanako kungaperekedwe mu rectum yanu pogwiritsa ntchito enema.

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

Musanalandire kusiyana kwa IV, uzani omwe akukuthandizani ngati mumamwa mankhwala a shuga metformin (Glucophage). Anthu omwe amamwa mankhwalawa angafunike kuima kwakanthawi. Komanso dziwitsani omwe akukuthandizani ngati muli ndi vuto ndi impso zanu. Kusiyanitsa kwa IV kumatha kukulitsa ntchito ya impso.

Fufuzani ngati makina a CT ali ndi malire ochepa ngati mulemera makilogalamu oposa 135 (135 kilograms). Kulemera kwambiri kumatha kuwononga sikani.

Muyenera kuchotsa zodzikongoletsera ndikuvala chovala mkati mwa phunziroli.

Anthu ena atha kukhala osasangalala pogona patebulo lolimba.

Kusiyanitsa komwe kumaperekedwa 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.

Kujambula kwa CT kumapanga zithunzi za thupi, kuphatikizapo ubongo, chifuwa, msana, ndi mimba. Mayeso atha kugwiritsidwa ntchito:

• Dziwani za matenda
• Atsogolereni dokotala kumalo oyenera panthawi yolemba
• Dziwani misala ndi zotupa, kuphatikiza khansa
• Phunzirani mitsempha ya magazi

Zotsatira zimawonedwa ngati zabwinobwino ngati ziwalo ndi mawonekedwe omwe akuyesedwa ndiwowoneka bwino.

Zotsatira zachilendo zimadalira gawo la thupi lomwe likuwerengedwa. Lankhulani ndi omwe amakupatsani za mafunso ndi nkhawa.

Zowopsa zokhala ndi ma CT scan ndi awa:

• Thupi lawo siligwirizana ndi utoto wosiyanitsa
• Kuwonongeka kwa impso kumagwiritsa ntchito utoto wosiyanitsa
• Chiwonetsero cha radiation

Kujambula kwa CT kumakuwonetsani ku radiation yambiri kuposa ma x-ray wamba. Kukhala ndi ma x-ray ambiri kapena ma CT scan pakapita nthawi kumatha kuwonjezera chiopsezo cha khansa. Komabe, chiwopsezo chojambulidwa kamodzi ndichaching'ono. Inu ndi dokotala muyenera kuyeza zoopsazi motsutsana ndi phindu lazidziwitso zomwe zingabwere kuchokera ku CT scan. Makina ambiri atsopano a CT amatha kuchepetsa kuchuluka kwa radiation.

Anthu ena ali ndi chifuwa chosiyanitsa utoto. Lolani wothandizira wanu adziwe ngati munayamba mwadwalapo utoto wosiyanitsa ndi jakisoni.

• Mtundu wofala kwambiri womwe umaperekedwa mumtsinje uli ndi ayodini. Ngati muli ndi vuto la ayodini, kusiyanasiyana kumatha kuyambitsa nseru kapena kusanza, kuyetsemula, kuyabwa, kapena ming'oma.
• Ngati mukuyenera kusiyanitsidwa motere, adokotala angakupatseni antihistamines (monga Benadryl) kapena steroids musanayesedwe.
• Impso zanu zimathandiza kuchotsa ayodini m'thupi. Mungafunike kulandira madzi owonjezera pambuyo pa mayeso kuti muthandize kutulutsa ayodini m'thupi lanu ngati muli ndi matenda ashuga kapena matenda a impso.

Kawirikawiri, utoto ungayambitse matenda omwe amachititsa kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda. Ngati mukuvutika kupuma panthawi yoyezetsa magazi, uzani operekera sikani nthawi yomweyo. Zitsulo zofufuzira zidazo zimabwera ndi intakomu ndiponso masipika, kuti munthu azimvanso nthawi zonse.
