Kujambula mtima kwa CT

Kujambula kwa mtima wa computed tomography (CT) ndi njira yojambulira yomwe imagwiritsa ntchito ma x-ray kupanga zithunzi mwatsatanetsatane za mtima ndi mitsempha yake yamagazi.

• Mayesowa amatchedwa coronary calcium scan mukamaliza kuti muwone ngati muli ndi calcium yambiri mumitsempha yamtima wanu.
• Amatchedwa CT angiography ngati atapangidwa kuti ayang'ane mitsempha yomwe imabweretsa magazi pamtima mwanu. Kuyesaku kumawunikira ngati pali kuchepa kapena kutsekeka m'mitsempha ija.
• Kuyesaku nthawi zina kumachitika limodzi ndi mapangidwe a mitsempha ya aorta kapena pulmonary kuti ayang'ane zovuta ndi zomangidwezo.

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

• Mudzagona chagada mutu wanu ndi miyendo kunja kwa sikani mbali iliyonse.
• Magulu ang'onoang'ono, otchedwa maelekitirodi amaikidwa pachifuwa ndi kulumikizidwa ndi makina omwe amalemba zochitika zamagetsi pamtima wanu. Mutha kupatsidwa mankhwala ochepetsa kugunda kwa mtima wanu.
• Mukakhala mkati mwa sikani, makina a x-ray azungulira mozungulira.

Kakompyuta imapanga zithunzi zosiyana za thupi, zotchedwa magawo.

• Zithunzi izi zitha kusungidwa, kuwonedwa pa polojekiti, kapena kusindikizidwa pafilimu.
• Zithunzi za 3D (zitatu-dimensional) zamtima zingapangidwe.

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

Kujambula konse kumangotenga pafupifupi mphindi 10.

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 (IV) m'manja mwanu kapena m'manja. Ngati kusiyanitsa kumagwiritsidwa ntchito, mungapemphedwenso kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 musanayesedwe.

Asanalandire kusiyanasiyana:

• Lolani wothandizira zaumoyo wanu adziwe ngati munakhalapo ndi vuto lotsutsana kapena mankhwala aliwonse. Mungafunike kumwa mankhwala musanayezedwe kuti mulandire mankhwalawa mosavutikira.
• Uzani wothandizira wanu za mankhwala anu onse, chifukwa mutha kufunsidwa kuti mukhale ndi zina, monga mankhwala a shuga metformin (Glucophage), musanayesedwe.
• Adziwitseni omwe akukuthandizani ngati muli ndi vuto la impso. Zinthu zosiyana zimatha kuyambitsa impso.

Ngati mukulemera makilogalamu opitilira 300 (135 kilograms), fufuzani ngati makina a CT ali ndi malire. Kulemera kwambiri kumatha kuwononga ziwalo zogwirira ntchito za sikani.

Mudzafunsidwa kuti muchotse zodzikongoletsera ndikuvala chovala chachipatala munthawi ya kafukufukuyu.

Anthu ena atha kukhala osasangalala pogona patebulo lolimba.

Kusiyanitsa komwe kumaperekedwa kudzera mu IV kumatha kuyambitsa:

• Kutentha pang'ono
• Kukoma kwachitsulo mkamwa
• Kutentha kwa thupi

Zomverera izi ndi zachilendo ndipo nthawi zambiri zimatha patangopita masekondi ochepa.

CT imapanga mwachangu zithunzi za mtima ndi mitsempha yake. Chiyesocho chitha kuzindikira kapena kuzindikira:

• Plaque buildup m'mitsempha yama coronary kuti mudziwe chiopsezo cha matenda amtima
• Matenda amtima obadwa nawo (mavuto amtima omwe amapezeka pakubadwa)
• Mavuto ndi ma valve amtima
• Kutseka kwamitsempha yomwe imapereka mtima
• Zotupa kapena unyinji wamtima
• Kupopera ntchito kwa mtima

Zotsatira zimawonedwa ngati zabwinobwino ngati mtima ndi mitsempha yomwe ikuwunikidwa ndiyabwino.

"Mapiritsi anu a calcium" amatengera kuchuluka kwa calcium yomwe imapezeka mumitsempha yamtima wanu.

• Mayesowa ndi abwinobwino (olakwika) ngati calcium yanu ili ndi 0. Izi zikutanthauza kuti mwayi wokhala ndi vuto la mtima pazaka zingapo zikubwerazi ndiwotsika kwambiri.
• Ngati kuchuluka kwa calcium ndikotsika kwambiri, ndiye kuti simungakhale ndi matenda amitsempha yamagazi.

Zotsatira zachilendo zitha kukhala chifukwa cha:

• Kuzindikira
• Matenda amtima obadwa nawo
• Mitsempha ya Coronary
• Mavuto a valavu yamtima
• Kutupa kwa chophimba kuzungulira mtima (pericarditis)
• Kupondereza mitsempha imodzi kapena iwiri (coronary artery stenosis)
• Zotupa kapena unyinji wina wamtima kapena madera oyandikana nawo

Ngati calcium yanu ili pamwamba:

• Zimatanthawuza kuti mumakhala ndi calcium m'makoma amitsempha yanu. Izi nthawi zambiri zimakhala chizindikiro cha atherosclerosis, kapena kuuma kwa mitsempha.
• Kukwera kwanu, vutoli likhoza kukhala lalikulu kwambiri.
• Lankhulani ndi omwe amakupatsani zomwe mungachite kuti muchepetse matenda amtima.

Zowopsa pazowunikira za CT ndi izi:

• Kuwonetsedwa ndi radiation
• Thupi lawo siligwirizana ndi utoto wosiyanitsa

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 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, mungafunike kumwa ma steroids (monga prednisone) kapena antihistamines (monga diphenhydramine) musanayesedwe. Muyeneranso kutenga histamine blocker (monga ranitidine).
• Impso zimathandiza kuchotsa ayodini m'thupi. 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. Ngati mukuvutika kupuma panthawi yoyesayo, muyenera kudziwitsa operekera makinawo nthawi yomweyo. Zitsulo zofufuzira zidazo zimabwera ndi intakomu ndiponso masipika, kuti munthu azimvanso nthawi zonse.
