Mutu wa CT
Kujambula kwa mutu wa computed tomography (CT) kumagwiritsa ntchito ma x-ray ambiri popanga zithunzi za mutu, kuphatikiza chigaza, ubongo, mabowo amaso, ndi sinus.
Mutu CT umachitika mchipatala kapena malo opangira ma radiology.
Mumagona pa tebulo laling'ono lomwe limalowa pakati pa makina a CT.
Mukakhala mkati mwa sikani, X-ray ya makina imayenda mozungulira inu.
Kakompyuta imapanga zithunzi zosiyana za thupi, zotchedwa magawo. Zithunzi izi zitha kukhala:
- Zosungidwa
- Inawonekera pa polojekiti
- Tasungidwa ku disc
Mitundu itatu yazithunzi zam'mutu imatha kupangidwa ndikulumikiza magawowo palimodzi.
Muyenera kukhala bata pakamayesa, chifukwa mayendedwe amayambitsa zithunzi zolakwika. Mutha kuuzidwa kuti musunge mpweya wanu kwakanthawi kochepa.
Kujambula kwathunthu kumatenga masekondi 30 okha mpaka mphindi zochepa.
Mayeso ena a CT amafunika utoto wapadera, wotchedwa zinthu zosiyana. Amaperekedwa m'thupi mayeso asanayambe. Kusiyanitsa kumathandizira madera ena kuwonekera bwino pa x-ray.
- Kusiyanitsa kumatha kuperekedwa kudzera mumitsempha (IV) m'manja mwanu kapena m'manja. Ngati kusiyanitsa kumagwiritsidwa ntchito, mungapemphedwenso kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 musanayesedwe.
- Lolani wothandizira zaumoyo wanu adziwe ngati mudachitapo kanthu posiyanitsa. Mungafunike kumwa mankhwala musanayezedwe kuti mulandire bwino.
- Musanalandire kusiyana, uzani omwe akukuthandizani ngati mumamwa mankhwala a shuga metformin (Glucophage). Mungafunike kusamala kwambiri. Komanso muuzeni omwe akukuthandizani ngati muli ndi vuto lililonse la ntchito ya impso popeza kusiyanitsa kwa IV kumatha kukulitsa vuto ili.
Ngati mukulemera makilogalamu oposa 135, fufuzani ngati makina a CT ali ndi polemera. Makina ena amachita.
Mudzafunsidwa kuti muchotse zodzikongoletsera ndipo mungafunike kuvala chovala chachipatala munthawi ya kafukufukuyu.
Ma x-ray opangidwa ndi CT scan sakhala opweteka. Anthu ena atha kukhala osasangalala pogona patebulo lolimba.
Kusiyanitsa zinthu zoperekedwa kudzera mu mtsempha kumatha kuyambitsa:
- Kumverera pang'ono
- Kukoma kwachitsulo mkamwa
- Kutentha kwa thupi
Izi si zachilendo ndipo nthawi zambiri zimatha pakangopita masekondi ochepa.
Mutu wa CT scan umalimbikitsidwa kuti uthandizire kuzindikira kapena kuwunika izi:
- Kubadwa (kobadwa nako) chilema cha mutu kapena ubongo
- Matenda aubongo
- Chotupa chaubongo
- Kupanga kwamadzimadzi mkati mwa chigaza (hydrocephalus)
- Kuvulala (kuvulala) kuubongo, kumutu, kapena kumaso
- Stroke kapena kutuluka magazi muubongo
Zingathenso kuchitidwa kufunafuna chifukwa cha:
- Kukula kwachilendo pamutu mwa ana
- Zosintha pakuganiza kapena machitidwe
- Kukomoka
- Mutu, mukakhala ndi zizindikilo zina
- Kutaya kwakumva (mwa anthu ena)
- Zizindikiro za kuwonongeka kwa gawo laubongo, monga mavuto amaso, kufooka kwa minofu, kufooka ndi kumva kulira, kusamva, kumva kuyankhula, kapena kumeza mavuto
Zotsatira zachilendo zitha kukhala chifukwa cha:
- Mitsempha yamagazi yosadziwika (malteriovenous malformation)
- Kutulutsa chotengera chamagazi muubongo (aneurysm)
- Kutuluka magazi (mwachitsanzo, subdural hematoma kapena kutuluka m'minyewa yaubongo)
- Matenda a mafupa
- Kutupa kwa ubongo kapena matenda
- Kuwonongeka kwa ubongo chifukwa chovulala
- Minofu ya ubongo kutupa kapena kuvulala
- Chotupa chaubongo kapena kukula kwina (misa)
- Kutaya minofu yaubongo (ubongo atrophy)
- Hydrocephalus
- Mavuto ndi mitsempha yakumva
- Stroke kapena chosakhalitsa ischemic attack (TIA)
Zowopsa pazowunikira za CT ndi izi:
- Kuwonetsedwa ndi radiation
- Thupi lawo siligwirizana ndi utoto wosiyanitsa
- Kuwonongeka kwa impso kuchokera ku utoto wosiyanitsa
Makina a CT amagwiritsa ntchito radiation kwambiri 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 omwe akukuthandizani muyenera kuyeza izi kuti musapindule ndi kupeza matenda oyenera.
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 munthu yemwe ali ndi vuto la ayodini wapatsidwa kusiyana kotere, nseru kapena kusanza, kuyetsemula, kuyabwa, kapena ming'oma kumatha kuchitika.
- Ngati mukuyenera kusiyanitsidwa motere, omwe amakupatsani akhoza kukupatsani ma antihistamines (monga Benadryl) kapena steroids musanayesedwe kuti muchepetse vuto lanu.
- Impso zimathandizira kuchotsa ayodini mthupi. Omwe ali ndi matenda a impso kapena matenda ashuga angafunikire kulandira madzi ena pambuyo poyesedwa kuti athandize ayodini kunja kwa thupi.
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 ndi masipika, kuti wina azimvanso nthawi zonse.
Kujambula kwa CT kumatha kuchepetsa kapena kupewa kufunika kwa njira zowonongera mavuto mumutu. Iyi ndi imodzi mwanjira zotetezeka kwambiri zophunzirira mutu ndi khosi.
Mayesero ena omwe angachitike m'malo mwa mutu wa CT scan ndi awa:
- MRI ya mutu
- Kujambula kwa positron emission tomography (PET) pamutu
Ubongo CT; Cranial CT; Kujambula kwa CT - chigaza; CT scan - mutu; Kujambula kwa CT - njira; CT scan - sinus; Kujambula tomography - cranial; Kujambula kwa CAT - ubongo
- Mutu CT
