Mwoyo CT scan

A computed tomography (CT) scan yemoyo inzira yekufungidzira iyo inoshandisa x-ray kugadzira mifananidzo yakajeka yemoyo nemidziyo yeropa.

• Uyu muedzo unonzi coronary calcium scan kana zvikaitwa kuti uone kana uine buildup yecalcium mumoyo mako arteri.
• Inonzi CT angiography kana ikaitwa kutarisa tsinga dzinounza ropa kumoyo wako. Iyi bvunzo inoongorora kana paine kutetepa kana kuvharika mune iwo arteri.
• Muedzo uyu dzimwe nguva unoitwa pamwe nekuyera kweiyo aorta kana pulmonary arteri kutsvaga matambudziko nezvimiro izvi.

Iwe uchakumbirwa kuti urere patafura yakamanikana iyo inotsvedza ichipinda pakati peiyo CT scanner.

• Iwe unorara nemusana nemusoro nemakumbo kunze kwe scanner kune ese magumo.
• Zvidimbu zvidiki, zvinonzi ma electrode anoiswa pachipfuva chako uye zvakabatana nemuchina unorekodha chiitiko chemagetsi emoyo wako. Unogona kupihwa mushonga wekudzora kurova kwemoyo wako.
• Paunenge iwe uri mukati me scanner, muchina x-ray danda rinotenderera zvakakukomberedza.

Komputa inogadzira mifananidzo yakaparadzana yenzvimbo yemuviri, inonzi zvidimbu.

• Iyi mifananidzo inogona kuchengetwa, kutariswa pane yekutarisa, kana kudhindwa pane firimu.
• 3D (matatu-mativi) mamodheru emoyo anogona kugadzirwa.

Iwe unofanirwa kunge wakanyarara panguva yebvunzo, nekuti kufamba kunokonzeresa mifananidzo. Unogona kuudzwa kuti ubate mweya wako kwenguva pfupi.

Iyo yose scan inofanira kungotora ingangoita maminetsi gumi.

Mimwe bvunzo inoda dhayi yakasarudzika, inonzi musiyano, kuti iendeswe mumuviri bvunzo isati yatanga. Musiyano unobatsira dzimwe nzvimbo kuratidza zvirinani pane ma-ray.

• Musiyano unogona kupihwa kuburikidza netsinga (IV) iri muruoko kana ruoko. Kana mutsauko ukashandiswa, iwe unogona zvakare kubvunzwa kuti usadye kana kunwa chero chinhu kwemaawa mana kusvika matanhatu usati waedzwa.

Usati wagamuchira mutsauko:

• Rega mupi wako wehutano azive kana iwe wakambove nemhinduro yekusiyanisa kana chero mishonga. Ungangoda kutora mishonga usati waedzwa kuitira kuti ugamuchire chinhu ichi zvakachengeteka.
• Udza mupiki wako nezvemishonga yako yese, nekuti unogona kukumbirwa kubata mimwe, senge chirwere cheshuga metformin (Glucophage), usati wayedzwa.
• Rega mupi wako azive kana uine matambudziko eitsvo. Musiyano wezvinhu unogona kukonzera itsvo kushanda kuti iwedzere.

Kana iwe uchirema anodarika mazana mapaundi (135 makirogiramu), tsvaga kana iyo CT muchina uine huremu hwehuremu. Kurema kwakanyanya kunogona kukonzera kukuvara kwenzvimbo dzekushanda dze scanner.

Iwe uchakumbirwa kubvisa zvishongo uye kupfeka jasi rechipatara panguva yekudzidza.

Vamwe vanhu vanogona kusagadzikana kubva pakurara patafura yakaoma.

Musiyano unopihwa kuburikidza neIV unogona kukonzera:

• Zvishoma kupisa kupisa
• Metallic kuravira mumuromo
• Kupisa kunodziya kwemuviri

Aya manzwiro akajairika uye anowanzoenda mukati memasekondi mashoma.

CT inokurumidza kugadzira mifananidzo yakajeka yemoyo uye arteri. Muedzo unogona kuongorora kana kuona:

• Plaque inovaka mumaronary artery kuti uone njodzi yako yechirwere chemwoyo
• Congenital chirwere chemoyo (matambudziko emwoyo aripo pakuzvarwa)
• Matambudziko nemavhavha emoyo
• Kuvharika kwetsinga dzinopa moyo
• Tumota kana masimba emoyo
• Kupomba basa kwemoyo

Mhedzisiro inoonekwa seyakajairika kana moyo uye arteri zviri kuongororwa zvakajairika pakuonekwa.

Yako "calcium score" yakavakirwa pahuwandu hwecalcium inowanikwa mumidziyo yemoyo wako.

• Chiyero chakajairika (chakaipa) kana calcium yako iri 0. Izvi zvinoreva kuti mukana wekurwara nemoyo mukati memakore anoverengeka anotevera wakanyanya kuderera.
• Kana iyo calcium mamaki iri yakaderera kwazvo, iwe haugone kuve necoronary arteri chirwere.

Mhedzisiro isina kujairika inogona kunge iri nekuda kwe:

• Aneurysm
• Congenital chirwere chemoyo
• Coronary tsinga chirwere
• Matambudziko emagetsi emoyo
• Kuzvimba kwekuvhara kwakatenderedza moyo (pericarditis)
• Kuwedzeredza kweimwe kana anopfuura coronary arteri (coronary artery stenosis)
• Mamota kana mamwe mamota emoyo kana nzvimbo dzakatenderedza

Kana yako calcium mamaki iri yakakwira:

• Zvinoreva kuti iwe une calcium buildup mumadziro eako coronary arteri. Izvi kazhinji chiratidzo che atherosclerosis, kana kuomarara kwetsinga.
• Iyo yakakwira mamaki ako, inozonyanya kuoma iri dambudziko.
• Taura nemupi wako nezve shanduko yemararamiro aunogona kuita kudzikisa njodzi yehosha yemoyo.

Ngozi dzeCCT scans dzinosanganisira:

• Kuve pachena kune radiation
• Allergic reaction yekusiyanisa dhayi

CT scans inokuratidzira iwe kune yakawanda radiation kupfuura yakajairwa x-ray. Kuva neakawanda ma-ray-ray kana CT scans nekufamba kwenguva kunogona kuwedzera njodzi yako yekenza. Nekudaro, njodzi kubva kune chero imwe scan iri diki. Iwe nemupi wako munofanira kuyera njodzi iyi kupokana nezvakanakira kuwana chirwere chakaringana pachinetso chekurapa.

Vamwe vanhu vane allergies kusiyanisa dhayi. Rega mupi wako azive kana iwe wakambove neanogadzirisa maitiro kune jekiseni musiyano dhayi.

• Rudzi rwekusiyanisa rwunopihwa mutsinga ine ayodini. Kana munhu ane ayodhini allergy akapiwa iyi mhando yekusiyanisa, kusvotwa kana kurutsa, kuhotsira, kuruma, kana mikoko inogona kuitika.
• Kana iwe zvachose uchifanira kupihwa musiyano wakadai, ungangoda kutora steroid (senge prednisone) kana antihistamines (senge diphenhydramine) usati waedzwa. Ungangodawo kutora histamine blocker (senge ranitidine).
• Itsvo dzinobatsira kubvisa ayodini kubva mumuviri. Vaya vane hosha yeitsvo kana chirwere cheshuga vangangoda kupihwa zvimwe zvinwiwa mushure mekuyedzwa kuti vabatsire kuburitsa ayodini kubva mumuviri.

Kazhinji, iyo dhayi inogona kukonzera hupenyu hunotyisidzira mhinduro yegoriki inonzi anaphylaxis. Kana iwe uine chero dambudziko rekufema mukati mekuyedzwa, iwe unofanirwa kuzivisa iyo scanner oparesheni nekukasira. Scanners inouya neintakcom uye masipika, kuti munhu anokwanisa kukunzwa nguva dzose.
