CT angiography - musoro nemutsipa

CT angiography (CTA) inosanganisa CT scan nejekiseni redhayi. CT inomirira computed tomography. Iyi nzira inokwanisa kugadzira mifananidzo yemidziyo yeropa mumusoro nemutsipa.

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-mativi emhando yemusoro uye mutsipa nzvimbo anogona kugadzirwa nekurongedza zvidimbu pamwechete.

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

Ma scan akazara anowanzotora masekonzi 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 mushonga weshuga 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.

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.

CTA yemusoro inogona kuitwa kutsvaga chikonzero che:

• Shanduko mukufunga kana maitiro
• Zvakaoma kududza mazwi
• Dzungu kana vertigo
• Kuona kaviri kana kurasikirwa kwemaonero
• Kufenda
• Kutemwa nemusoro, kana uine zvimwe zviratidzo kana zviratidzo
• Kunzwa kurasikirwa (mune vamwe vanhu)
• Unhu kana kugwinha, kazhinji pachiso kana mumusoro
• Kumedza matambudziko
• Kurohwa
• Yenguva ischemic kurwisa (TIA)
• Kushaya simba mune chimwe chikamu chemuviri wako

CTA yemutsipa inogona zvakare kuitwa:

• Mushure mekukuvara kumutsipa kutsvaga kukuvara mumidziyo yeropa
• Zvekuronga usati waitwa carotid tsinga yekuvhiya
• Zvekuronga zvehuropi bundu kuvhiyiwa
• Zvekufungidzirwa vasculitis (kuzvimba kweropa remidziyo masvingo)
• Zvekufungidzirwa zvisina kujairika mitsipa yeropa muuropi

Mhedzisiro inoonekwa seyakajairika kana pasina matambudziko anoonekwa.

Mhedzisiro isina kujairika inogona kunge iri nekuda kwe:

• Mitezo yeropa isina kujairika (arteriovenous malformation).
• Kubuda ropa muuropi (semuenzaniso, subdural hematoma kana nzvimbo yekubuda ropa).
• Brain bundu kana kumwe kukura (uremu).
• Kurohwa.
• Akamanikana kana akavharika aroti carotid. (Tsinga dzema carotid dzinopa chikuru kupa ropa kuuropi hwako. Dziri kune rumwe rutivi rwemutsipa wako.)
• Yakaderedzwa kana yakavharika vertebral artery mumutsipa. (Iyo vertebral arteries inopa ropa kuyerera kumashure kweuropi.)
• Musodzi mumadziro etsinga (dissection).
• Nzvimbo isina kusimba mumadziro eropa rinoita kuti tsinga yeropa ibude kana bharuni kunze (aneurysm).

Ngozi dzeCCT scans dzinosanganisira:

• Kuve pachena kune radiation
• Allergic reaction kune iyo kusiyanisa dhayi
• Kukuvadza kune itsvo kubva 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) kana steroids pamberi pekuyedzwa.
• Itsvo dzinobatsira kubvisa ayodini kubva mumuviri. Vanhu vane chirwere cheitsvo kana chirwere cheshuga vangangoda kupihwa zvimwe zvinwiwa mushure mekuyedzwa kuti vabatsire kuburitsa iodini kunze kwemuviri.

Kazhinji, iyo dhayi inogona kukonzera hupenyu hunotyisidzira mhinduro yegoriki inonzi anaphylaxis. Udza openengura ipapo ipapo kana uine dambudziko rekufema panguva yekuyedzwa. Scanners inouya neintakcom uye masipika, kuti munhu anokwanisa kukunzwa nguva dzose.

A CT scan inogona kudzora kana kudzivirira kudiwa kweinokuvadza maitiro ekuongorora matambudziko mudehenya. Iyi ndiyo imwe yenzira dzakachengeteka kwazvo dzekudzidza musoro nemutsipa.

Mimwe bvunzo inogona kuitwa panzvimbo yeCT scan yemusoro inosanganisira:

• MRI yemusoro
• Positron emission tomography (PET) scan yemusoro
