CT angiography - maoko nemakumbo

CT angiography inosanganisa CT scan nejekiseni redhayi. Iyi nzira inokwanisa kugadzira mifananidzo yemidziyo yeropa mumaoko kana mumakumbo. CT inomirira computed tomography.

Iwe ucharara pamusoro petafura nhete iyo inotsvedza ichipinda pakati peiyo CT scanner.

Paunenge uri mukati ma scanner, muchina wacho x-ray danda rinotenderera zvakakukomberedza. Scanners dzazvino "zononoka" dzinogona kuita bvunzo dzisingamire.

Komputa inogadzira mifananidzo yakawanda yenzvimbo yemuviri, inonzi zvidimbu. Iyi mifananidzo inogona kuchengetwa, kutariswa pane yekutarisa, kana kudhindwa pane firimu. Mienzaniso yenzvimbo yemuviri mumatatu-mativi inogona kugadzirwa nekuwedzera zvidimbu pamwechete.

Iwe unofanirwa kuramba wakadzikama panguva yebvunzo, nekuti kufamba kunokanganisa mifananidzo. Unogona kumbobata mweya wako kwenguva pfupi.

Iyo scan inofanira kutora ingangoita maminetsi mashanu.

Mimwe bvunzo inoda dhayi yakasarudzika, inonzi musiyano, kujekeswa mumuviri wako bvunzo isati yaitwa. Musiyano unobatsira dzimwe nzvimbo kuratidza zvirinani pane ma-ray.

• Musiyano unogona kupihwa kuburikidza netsinga (IV) iri muruoko kana ruoko. Kana mutsauko ukashandiswa, iwe zvakare unogona 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 kuti udzivise dambudziko iri.
• Usati wagamuchira musiyano, udza mupi wako kana iwe ukatora mushonga weshuga metformin (Glucophage). Ungangoda kutora mamwe matanho kana uri kutora mushonga uyu.

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

Kurema kwakanyanya kunogona kukonzera kukuvara kwenzvimbo dzekushanda dze scanner. Kana iwe uchirema anodarika mazana matatu emakirogiramu (135 kilograms), taura nachiremba wako nezvehuremu hwekuyera usati wayedzwa.

Iwe unozofanirwa kubvisa zvishongo uye kupfeka chipfeko chechipatara panguva yeCT bvunzo.

Vamwe vanhu vanogona kunge vasina kugadzikana vakarara patafura yakaoma.

Musiyano unopihwa kuburikidza neIV unogona kukonzera:

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

Aya manzwiro akajairwa uye anowanzoenda mukati memasekondi mashoma.

Iwe ungangoda bvunzo iyi kana iwe uine zviratidzo zvekutetepa kana kuvharirwa ropa tsinga mumaoko, maoko, makumbo, kana tsoka.

Muedzo unogona zvakare kuitwa kuti uongorore:

• Kuwedzera zvisina kujairika kana kubharumu kwechikamu chetsinga (aneurysm)
• Kubuda ropa
• Kuzvimba kana kuzvimba kwemitsipa yeropa (vasculitis)
• Kurwadziwa kwegumbo panguva yekufamba kana kurovedza muviri (claudication)

Mhedzisiro inoonekwa seyakajairika kana pasina matambudziko anoonekwa.

Mhedzisiro isingawanzo kazhinji inowanzoitika nekuda kwekutetepa uye kuomarara kwetsinga dzemaoko kana makumbo kubva kubwe rakavakwa mumadziro etsinga

Iyo x-ray inogona kuratidza kuvhara mukati memidziyo inokonzerwa ne:

• Kuwedzera zvisina kujairika kana kubharumu kwechikamu chetsinga (aneurysm)
• Ropa rinovhara
• Zvimwe zvirwere zvetsinga

Mhedzisiro isina kujairika inogona zvakare kuve nekuda kwe:

• Kuzvimba kwemitsipa yeropa
• Kukuvadza kumidziyo yeropa
• Buerger chirwere (thromboangiitis obliterans), chirwere chisingawanzoitika umo tsinga dzeropa dzemaoko nemakumbo dzinovharika
  

Ngozi dzeCCT scans dzinosanganisira:

• Kujekesa kune radiation
• Allergy kusiyanisa dhayi
• Kukuvadza kune itsvo kubva kune rakasiyana dhayi

CT scan inopa 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 kukurukura nezvengozi iyi muchienzanisa nekukosha kwekuongororwa kwechokwadi kwedambudziko iri. Ma scanner mazhinji emazuva ano anoshandisa nzira dzekushandisa mwaranzi shoma.

Rega mupi wako azive kana iwe wakambove neanogadzirisa maitiro kune jekiseni musiyano dhayi.

• Rudzi rwakanyanya kujairika rwekusiyanisa rine 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 uchida kuve nerudzi urwu rwekusiyanisa, wako mupi anogona kukupa iwe antihistamines (senge Benadryl) kana steroids pamberi pekuyedzwa.
• Itsvo dzinobatsira kubvisa ayodini kubva mumuviri. Unogona kuda mamwe emvura mushure mekuedzwa kuti ubatsire kubvisa muviri wako ayodini kana uine chirwere cheitsvo kana chirwere cheshuga.

Kazhinji, dhayi inogona kukonzeresa kukonzeresa kurwara kunodaidzwa kunzi anaphylaxis. Izvi zvinogona kutyisidzira hupenyu. Zivisa scanner opareta ipapo kana uine dambudziko rekufema panguva yekuedzwa. Scanners ine intercom uye masipika kuitira kuti anoshanda anzwe iwe nguva dzose.

Yakagadzirwa tomography angiography - peripheral; CTA - mhiri; CTA - Runoff; PAD - CT angiography; Peripheral arteri chirwere - CT angiography; PVD - CT angiography
