CT angiography - mutu ndi khosi

CT angiography (CTA) imaphatikiza CT scan ndi jakisoni wa utoto. CT imayimira computed tomography. Njira imeneyi imatha kupanga zithunzi zamitsempha yamagazi pamutu ndi m'khosi.

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

Mukakhala mkati mwa sikani, X-ray ya makina imayenda mozungulira inu.

Kompyutayi imapanga zithunzi zambiri za thupi, zotchedwa magawo. Zithunzi izi zitha kusungidwa, kuwonedwa pa polojekiti, kapena kusindikizidwa pafilimu. Mitundu yazithunzi zitatu za mutu ndi khosi zitha kupangidwa ndikulunga magawo palimodzi.

Muyenera kukhala bata pakamayesa, chifukwa mayendedwe amayambitsa zithunzi zolakwika. Mutha kuuzidwa kuti musunge mpweya wanu kwakanthawi kochepa.

Kujambula kwathunthu kumangotenga masekondi ochepa. Makina atsopanowa atha kujambulitsa thupi lanu lonse, kumutu mpaka kumapazi, pasanathe masekondi 30.

Mayeso ena amafuna utoto wapadera, wotchedwa kusiyanasiyana, kuti uperekedwe mthupi 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.

Kusiyanaku kumatha kukulitsa mavuto amachitidwe a impso mwa anthu omwe ali ndi impso zosagwira bwino ntchito. Lankhulani ndi omwe amakupatsani ngati muli ndi vuto la impso.

Kulemera kwambiri kumatha kuwononga sikani. Ngati mukulemera makilogalamu opitilira 300 (135 kilograms), lankhulani ndi omwe amakupatsirani za malire anu asanayesedwe.

Mudzafunsidwa kuti muchotse zodzikongoletsera ndikuvala chovala chachipatala munthawi ya kafukufukuyu.

Anthu ena atha kukhala osasangalala pogona patebulo lolimba.

Ngati muli ndi kusiyana pamitsempha, mutha kukhala ndi:

• Kumverera pang'ono
• Kukoma kwachitsulo mkamwa mwako
• Kutentha kwa thupi lanu

Izi si zachilendo ndipo nthawi zambiri zimatha pakangopita masekondi ochepa.

CTA yamutu itha kuchitidwa kuti mufufuze chifukwa cha:

• Zosintha pakuganiza kapena machitidwe
• Zovuta kutchula mawu
• Chizungulire kapena vertigo
• Kuwona kawiri kapena kutayika kwamaso
• Kukomoka
• Mutu, mukakhala ndi zizindikilo zina
• Kutaya kwakumva (mwa anthu ena)
• Dzanzi kapena kumva kulasalasa, nthawi zambiri kumaso kapena kumutu
• Kumeza mavuto
• Sitiroko
• Kuukira kwanthawi yayitali (TIA)
• Kufooka mu gawo limodzi la thupi lanu

CTA ya khosi itha kuchitidwanso:

• Pambuyo povulazidwa m'khosi kuti muwone kuwonongeka kwa mitsempha yamagazi
• Pokonzekera musanachite opaleshoni yamitsempha yama carotid
• Pokonzekera opareshoni ya chotupa muubongo
• Kwa amaganiziridwa vasculitis (kutupa kwa makoma amitsempha yamagazi)
• Kwa amaganiziridwa mitsempha yachilendo muubongo

Zotsatira zimawonedwa ngati zabwinobwino ngati palibe zovuta zowoneka.

Zotsatira zachilendo zitha kukhala chifukwa cha:

• Mitsempha yamagazi yachilendo (arteriovenous malformation).
• Kutuluka magazi muubongo (mwachitsanzo, subdural hematoma kapena dera lamagazi).
• Chotupa chaubongo kapena kukula kwina (misa).
• Sitiroko.
• Mitsempha yochepetsedwa kapena yotsekedwa ya carotid. (Mitsempha ya carotid imapereka magazi ambiri kuubongo wanu. Amakhala mbali zonse za khosi lanu.)
• Mitsempha yochepetsetsa kapena yotsekedwa m'khosi. (Mitsempha yamitsempha yamagazi imapereka magazi kuthamangira kumbuyo kwa ubongo.)
• Misozi kukhoma la mtsempha wamagazi (kutsekeka).
• Malo ofooka pakhoma lamitsempha yamagazi yomwe imapangitsa kuti magazi azituluka kapena buluni (aneurysm).

Zowopsa pazowunikira za CT ndi izi:

• Kuwonetsedwa ndi radiation
• Thupi lawo siligwirizana ndi utoto wosiyanitsa
• Kuwonongeka kwa impso kuchokera ku utoto

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. Makina ambiri amakono amagwiritsa ntchito njira zochepa poyerekeza ndi ma 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, mutha kukhala ndi nseru kapena kusanza, kuyetsemula, kuyabwa, kapena ming'oma mukapeza kusiyana kotere.
• Ngati mukuyenera kusiyanitsidwa motere, omwe amakupatsani akhoza kukupatsani ma antihistamine (monga Benadryl) kapena steroids musanayesedwe.
• Impso zimathandiza kuchotsa ayodini m'thupi. Anthu omwe ali ndi matenda a impso kapena matenda ashuga angafunikire kulandira madzi ena pambuyo poyesedwa kuti athandize ayodini kunja kwa thupi.

Kawirikawiri, utoto ungayambitse matenda omwe amachititsa kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda. Uzani opangayo nthawi yomweyo ngati zikukuvutani kupuma panthawi yoyezetsa. Zitsulo zofufuzira zidazo zimabwera ndi intakomu ndiponso masipika, kuti munthu 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 CT scan pamutu ndi awa:

• MRI ya mutu
• Kujambula kwa positron emission tomography (PET) pamutu

Kujambula tomography angiography - ubongo; CTA - chigaza; CTA - chisokonezo; Mutu wa TIA-CTA; Stroke-CTA mutu; Kujambula tomography angiography - khosi; CTA - khosi; Mitsempha ya Vertebral - CTA; Mtsempha wamagazi wa carotid stenosis - CTA; Vertebrobasilar - CTA; Kuzungulira kwaposachedwa ischemia - CTA; Khosi la TIA - CTA; Stroke - CTA khosi
