CT angiography - chipfuva

CT angiography inosanganisa CT scan nejekiseni redhayi. Iyi nzira inokwanisa kugadzira mifananidzo yemidziyo yeropa mubhokisi uye mudumbu repamusoro. CT inomirira computed tomography.

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

Paunenge uri mukati ma scanner, muchina wacho x-ray danda rinotenderera zvakakukomberedza.

Komputa inogadzira mifananidzo yakawanda yakapatsanurwa yenzvimbo yemuviri, inonzi zvidimbu. Iyi mifananidzo inogona kuchengetwa, kutariswa pane yekutarisa, kana kudhindwa pane firimu. Matatu-matatu emhando dzechipfuva anogona kugadzirwa nekukochekera zvidimbu pamwechete.

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

Ma scan akazara anowanzo kutora maminetsi mashoma. Iwo ma scanner matsva anogona kufananidza muviri wako wese, musoro kune chigunwe, mumasekondi asingasviki makumi matatu.

Mimwe bvunzo inoda dhayi yakasarudzika, inonzi musiyano, kuti iendeswe mumuviri bvunzo isati yatanga. Musiyano unobatsira dzimwe nzvimbo kuratidza zvirinani pane x-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.
• Rega mupi wako wekuchengetedza hutano azive kana iwe wakambove nemhinduro yekusiyanisa. Ungangoda kutora mishonga usati waedzwa kuitira kuti ugamuchire zvakachengeteka.
• Usati wagamuchira musiyano, udza mupi wako kana iwe ukatora chirwere cheshuga mishonga metformin (Glucophage). Ungangoda kutora matanho ekuwedzera.

Musiyano unogona kukuvadza itsvo kushanda matambudziko muvanhu vane itsvo dzisingashande. Taura nemupi wako kana uine nhoroondo yeitsvo matambudziko.

Kurema kwakanyanya kunogona kukuvadza iyo scanner. Kana iwe uchirema anodarika mazana mapaundi (135 makirogiramu), taura nemupi wako nezvehuremu hwehuremu usati wayedzwa.

Iwe uchakumbirwa kubvisa zvishongo uye kupfeka jasi rechipatara panguva yekudzidza.

MaX-ray anogadzirwa neCT scan haarwadze. Vamwe vanhu vanogona kusagadzikana kubva pakurara patafura yakaoma.

Kana iwe uine mutsauko kuburikidza netsinga, unogona kuve ne:

• Kunzwa kupisa zvishoma
• Metallic kuravira mumuromo mako
• Kupisa kunodziya kwemuviri wako

Izvi zvakajairika uye zvinowanzoenda mukati memasekondi mashoma.

Chifuva CT angiogram inogona kuitwa:

• Nezviratidzo zvinoratidza kuwanda kweropa mumapapu, sekurwadziwa pachipfuva, kufema nekukurumidza, kana kufema kwekufema
• Mushure mekukuvara kwepfupa kana kushungurudzika
• Asati avhiyiwa mumapapu kana muchipfuva
• Kutsvaga inogona kuwanikwa saiti yekuisa catheter yehemodialysis
• Zvekuzvimba kwechiso kana maoko ekumusoro asingakwanise kutsanangurwa
• Kutsvaga kufungidzirwa kwekuzvarwa kwekuremara kweaorta kana imwe mitsipa yeropa mubhokisi
• Kutsvaga kubhaluni kuwedzera kweteri (aneurysm)
• Kutsvaga misodzi mune arteri (dissection)

Mhedzisiro inoonekwa seyakajairika kana pasina matambudziko anoonekwa.

Chipfuva CT inogona kuratidza kusagadzikana kwakawanda kwemoyo, mapapu, kana nzvimbo yechifuva, kusanganisira:

• Kufungidzirwa kuvhara kweiyo yepamusoro vena cava: Iyi tsinga hombe inofambisa ropa kubva kumusoro kwehafu yemuviri kuenda pamoyo.
• Ropa clot (s) mumapapu.
• Kukanganisika kwemitsipa yeropa mumapapu kana chipfuva, senge aortic arch syndrome.
• Aortic aneurysm (munzvimbo yechipfuva).
• Kudimbudzira kwechikamu chetsinga huru inotungamira kunze kwemoyo (aorta).
• Kubvarura pamadziro etsinga (kupatsanura).
• Kuzvimba kweropa remidziyo masvingo (vasculitis).

Ngozi dzeCCT scans dzinosanganisira:

• Kuve pachena kune radiation
• Allergic reaction yekusiyanisa dhayi
• Kukuvadza kune itsvo kubva kusiyanisa dhayi

CT scan inoshandisa yakawanda radiation kupfuura yakajairwa x-rays. 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. Ma scanner mazhinji emazuva ano anoshandisa nzira dzekushandisa mwaranzi shoma.

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 iwe uine ayodhini allergy, iwe unogona kunge uine kusvotwa kana kurutsa, kunyemwerera, kuruma, kana mikoko kana iwe ukawana iri mhando remusiyano.
• Kana iwe zvachose uchifanira kupihwa musiyano wakadai, mupi wako anogona kukupa antihistamines (senge Benadryl) uye / kana steroids pamberi pekuedzwa.
• 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 nematauri, kuti mumwe munhu akunzwe nguva dzose.
