Kujambula kwa CT

Makina owerengera a tomography (CT) a njira yozungulira ndi njira yoyerekeza. Imagwiritsa ntchito ma x-ray kupanga zithunzi mwatsatanetsatane zazitsulo zamaso (zozungulira), maso ndi mafupa ozungulira.

Mudzafunsidwa kuti mugone patebulo lochepetsetsa lomwe limalowa pakati pa chojambulira cha CT. Mutu wanu wokha umayikidwa mkati mwa makina a CT.

Mutha kuloledwa kupumula mutu wanu pamtsamiro.

Mukakhala mkati mwa sikani, x-ray ya makina imazungulira mozungulira koma simudzawona x-ray.

Kakompyuta imapanga zithunzi zosiyana za thupi, zotchedwa magawo. Zithunzi izi zitha kusungidwa, kuwonedwa pa polojekiti, kapena kusindikizidwa pafilimu. Kompyutayo imatha kupanga magawo azithunzi zazithunzi zitatu zakuthupi polumikiza magawo palimodzi.

Muyenera kugona pakadali mayeso, chifukwa mayendedwe amabweretsa zithunzi zosawoneka bwino. Mutha kupemphedwa kuti musunge mpweya wanu kwakanthawi kochepa.

Kujambula kwenikweni kumatenga pafupifupi masekondi 30. Ntchito yonseyi imatenga pafupifupi mphindi 15.

Asanayesedwe:

• Mudzafunsidwa kuti muchotse zodzikongoletsera ndikuvala chovala chachipatala munthawi ya kafukufukuyu.
• Ngati mukulemera makilogalamu opitilira 300 (135 kilograms), fufuzani ngati makina a CT ali ndi malire. Kulemera kwambiri kumatha kuwononga ziwalo zogwirira ntchito za sikani.

Mayeso ena amafuna utoto wapadera, wotchedwa kusiyanasiyana, kuti uperekedwe mthupi mayeso asanayambe. Kusiyanitsa kumathandizira madera ena kuwonekera bwino pama x-ray. Kusiyanitsa kumatha kuperekedwa kudzera mumitsempha (intravenous- IV) yomwe ili mdzanja lanu kapena patsogolo.

Musanagwiritse ntchito sikani, ndikofunikira kudziwa izi:

• Mutha kupemphedwa kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 mayeso asanayesedwe.
• Lolani wothandizira zaumoyo wanu adziwe ngati mudachitapo kanthu posiyanitsa. Mungafunike kumwa mankhwala musanayezedwe kuti mulandire mankhwalawa mosavutikira.
• Uzani wothandizira wanu ngati mutamwa mankhwala a shuga metformin (Glucophage). Mungafunike kusamala kwambiri.
• Lolani wothandizira wanu ngati ali ndi vuto la impso. Izi ndichifukwa choti kusiyanako kumatha kukulitsa ntchito ya impso.

Anthu ena atha kukhala osasangalala pogona patebulo lolimba.

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

Kuyesaku ndikothandiza kupeza matenda omwe amakhudza madera otsatirawa:

• Mitsempha yamagazi
• Minofu yamaso
• Mitsempha yotulutsa maso (mitsempha yamawonedwe)
• Zojambula

Njira yozungulira ya CT itha kugwiritsidwanso ntchito kuzindikira:

• Abscess (matenda) am'deralo
• Fupa losweka lamaso
• Chinthu chachilendo pamalowo

Zotsatira zachilendo zingatanthauze:

• Magazi
• Fupa losweka lamaso
• Matenda amanda
• Matenda
• Chotupa

Kujambula kwa CT ndi ma x-ray ena amayang'aniridwa mosamala ndikuwongolera kuti awonetsetse kuti agwiritsa ntchito radiation yochepa. Chiwopsezo chokhudzana ndi kusanthula kulikonse ndichotsika kwambiri. Chiwopsezo chikuwonjezeka pomwe maphunziro ambiri amachitika.

Kuyeza kwa CT kumachitika pomwe maubwino ake amaposanso zoopsa zake. Mwachitsanzo, zitha kukhala zowopsa kusayesedwa, makamaka ngati omwe amakupatsani akuganiza kuti mwina muli ndi khansa.

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.
• Ngati muli ndi ziwengo zosiyana koma mukuzifuna kuti muyesedwe bwino, mutha kulandira antihistamines (monga Benadryl) kapena steroids musanayesedwe.

Impso zimathandiza kusefa ayodini kunja kwa thupi. Ngati muli ndi matenda a impso kapena matenda ashuga, muyenera kuyang'anitsitsa mavuto a impso pambuyo poti kusiyanasiyana kwaperekedwa. Ngati muli ndi matenda ashuga kapena matenda a impso, lankhulani ndi omwe amakupatsani chithandizo isanayezedwe kuti mudziwe zoopsa zanu.

Musanalandire kusiyana, auzeni omwe akukuthandizani ngati mutamwa mankhwala a shuga metformin (Glucophage) chifukwa mungafunike kusamala kwambiri. Muyenera kuyimitsa mankhwalawo kwa maola 48 mutayesedwa.

Nthawi zambiri, utoto umatha kuyambitsa matenda omwe amatchedwa anaphylaxis. Ngati mukuvutika kupuma panthawi yoyezetsa magazi, uzani opareshoni nthawi yomweyo. Zitsulo zofufuzira zidazo zimabwera ndi intakomu ndiponso masipika, kuti munthu azimvanso nthawi zonse.
