CT angiography - dumbu uye chiuno

CT angiography inosanganisa CT scan nejekiseni redhayi. Iyi nzira inokwanisa kugadzira mifananidzo yemidziyo yeropa mudumbu rako (mudumbu) kana nzvimbo yepelvis. CT inomirira computed tomography.

Iwe ucharara pamusoro petafura nhete iyo inotsvedza ichipinda pakati peiyo CT scanner. Kazhinji kazhinji, iwe unovata nemusana nemawoko ako akasimudzwa pamusoro pemusoro wako.

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

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

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

Iyo scan inofanira kutora isingasviki maminetsi makumi matatu.

Iwe unofanirwa kuve uine yakasarudzika dhayi, inonzi musiyano, isa mumuviri wako pamberi peimwe bvunzo. 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.
• Iwe unogona zvakare kunwa musiyano wakasiyana pamberi pebvunzo. Paunonwa musiyano unoenderana nerudzi rwebvunzo riri kuitwa. Misiyano ine kuravira kwechalky, kunyange hazvo vamwe vane zvinwiwa kuitira kuti vanzwe zvirinani zvishoma. Musiyano uchapfuura uchibva mumuviri wako kuburikidza nezvituru zvako.
• Rega mupi wako wekuchengetedza hutano azive kana iwe wakambove nemhinduro yekusiyanisa. Ungangoda kutora mishonga usati waedzwa kuitira kuti ugamuchire chinhu ichi zvakachengeteka.
• Usati wagamuchira musiyano, udza mupi wako kana iwe ukatora mushonga weshuga metformin (Glucophage). Vanhu vari kutora mushonga uyu vanogona kumbomira kuutora kwenguva yakati bvunzo usati waitwa.

Musiyano unogona kukuvadza itsvo kushanda matambudziko muvarwere 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.

Unofanira kubvisa zvishongo zvako uye kupfeka hanzu yechipatara panguva yechidzidzo.

Kurara patafura yakaoma kunogona kunge kusinganzwisisike.

Kana iwe uine mutsauko kuburikidza netsinga, unogona kuve ne:

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

Aya manzwiro akajairika uye anoenda mukati memasekondi mashoma.

A CT angiography scan inokurumidza kujekesa mifananidzo yemidziyo yeropa mukati medumbu rako kana pelvis.

Bvunzo iyi inogona kushandiswa kutsvaga:

• Kuwedzera zvisina kujairika kana kubharumu kwechikamu chetsinga (aneurysm)
• Kunobva ropa rinotanga mumatumbu kana kumwe kunhu mudumbu kana muchiuno
• Masasi uye mamota mudumbu kana muchiuno, kusanganisira kenza, pazvinodiwa kubatsira kuronga kurapwa
• Chikonzero chekutambudzika mudumbu kunofungidzirwa kuve nekuda kwekudzikira kana kuvhara kweimwe kana yakawanda yetsinga dzinopa diki uye hombe ura
• Marwadzo mumakumbo anofungidzirwa kuve nekuda kwekudzikira kwetsinga dzeropa dzinopa makumbo netsoka
• Yakakwira BP nekuda kwekudzikira kwetsinga dzinoendesa ropa kuitsvo

Muedzo zvakare unogona kushandiswa pamberi:

• Kuvhiya pamitsipa yeropa yechiropa
• Itsvo kuisazve

Mhedzisiro inoonekwa seyakajairika kana pasina matambudziko anoonekwa.

Mhedzisiro isina kujairika inogona kuratidza:

• Kunobva ropa mukati medumbu kana chiuno
• Kuderedza kweiyo arter inopa itsvo
• Kuderedza tsinga dzinopa ura
• Kuderedza tsinga dzinopa makumbo
• Ballooning kana kuzvimba kweteri (aneurysm), kusanganisira iyo aorta
• Musodzi mumadziro eota

Ngozi dzeCCT scans dzinosanganisira:

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

CT inoongorora inokuratidzira iwe kune yakawanda radiation kupfuura yakajairwa x-ray. Mazhinji ma-ray-ray kana CT anoongorora pamusoro penguva anogona kuwedzera njodzi yako yekenza. Nekudaro, njodzi kubva kune chero imwe scan iri diki. Taura nemupi wako wezvehutano nezve njodzi iyi uye kubatsirwa kweye bvunzo yekuwana chaiyo kuongororwa kwedambudziko rako rekurapa. 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 uchifanirwa kupihwa musiyano wakadai, mupi wako anogona kukupa antihistamines (senge Benadryl) kana steroids pamberi pekuyedzwa.

Itsvo dzako dzinobatsira kubvisa ayodini kubva mumuviri. Iwe ungangoda mamwe emvura mushure mekuyedzwa kubatsira kuburitsa iodine kubva mumuviri wako kana uine chirwere cheitsvo kana chirwere cheshuga.

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.
