Orbit CT scan

Iyo computed tomography (CT) scan yeiyo orbit inzira yekufungidzira. Iyo inoshandisa x-mwara kugadzira yakajeka mifananidzo yemeso eziso (mabheji), maziso nemapfupa akapoterera.

Iwe uchakumbirwa kuti urere patafura yakamanikana iyo inotsvedza ichipinda pakati peiyo CT scanner. Musoro wako chete ndiwo unoiswa mukati meCCT scanner.

Iwe unogona kubvumidzwa kuzorora musoro wako pamutsago.

Paunenge iwe uri mukati me scanner, muchina x-ray danda rinotenderera zvakakukomberedza asi hauzoone x-ray.

Komputa inogadzira mifananidzo yakaparadzana yenzvimbo yemuviri, inonzi zvidimbu. Iyi mifananidzo inogona kuchengetwa, kutariswa pane yekutarisa, kana kudhindwa pane firimu. Iyo komputa inogona kugadzira matatu-mativi mamodheru enzvimbo yemuviri nekurongedza zvidimbu pamwechete.

Unofanira kunyepera kunyarara panguva yebvunzo, nekuti kufamba kunokonzeresa mifananidzo. Iwe unogona kukumbirwa kubata mweya wako kwenguva pfupi.

Iyo chaiyo scan inotora anenge masekondi makumi matatu. Maitiro ese anotora maminetsi gumi nemashanu.

Pamberi bvunzo:

• Iwe uchakumbirwa kubvisa zvishongo uye kupfeka jasi rechipatara panguva yekudzidza.
• 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.

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 (intravenous- IV) muruoko kana ruoko.

Pamberi pe scan uchishandisa musiyano, zvakakosha kuti uzive zvinotevera:

• Iwe unogona kukumbirwa 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 chinhu ichi zvakachengeteka.
• Udza mupi wako kana iwe ukatora mushonga weshuga metformin (Glucophage). Ungangoda kutora matanho ekuwedzera.
• Rega mupi wako azive kana uine hurombo hweitsvo. Izvi zvinodaro nekuti mutsauko unogona kukuvadza basa reitsvo.

Vamwe vanhu vanogona kusagadzikana kubva pakurara patafura yakaoma.

Musiyano unopihwa kuburikidza neIV unogona kukonzeresa kupisa. Iwe unogona zvakare kuve nesimbi kuravira mumuromo uye kupisa kwakadziya kwemuviri. Aya manzwiro akajairika uye kazhinji anoenda mukati memasekondi mashoma.

Muedzo uyu unobatsira kuongorora zvirwere zvinokanganisa nzvimbo dzinotevera dzakatenderedza maziso.

• Tsinga
• Tsinga dzemaziso
• Tsinga dzinopa maziso (optic nerves)
• Sinuses

An orbit CT scan inogona zvakare kushandiswa kuona:

• Kuputirwa (hutachiona) kwenzvimbo yeziso
• Yakaputsika ziso soketi pfupa
• Chinhu chekune imwe nyika musoketi yeziso

Mhedzisiro isina kujairika inogona kureva:

• Kubuda ropa
• Yakaputsika ziso soketi pfupa
• Graves chirwere
• Utachiona
• Bundu

CT inoongorora uye mamwe ma-x-ray anotariswa uye kudzorwa kuti ave nechokwadi chekuti vanoshandisa mashoma emwaranzi. Ngozi inosanganisirwa nechero munhu scan yakaderera kwazvo. Iyo njodzi inowedzera sezvo zvimwe zvidzidzo zvaitwa.

CT scans inoitwa kana mabhenefiti akanyanya kukunda njodzi. Semuenzaniso, zvinogona kuve nenjodzi yekusave nemubvunzo, kunyanya kana mupi wako achifunga kuti ungave uine kenza.

Rudzi rwekusiyanisa rwunopihwa mutsinga ine ayodini.

• Kana munhu ane ayodhini allergy akapiwa iyi mhando yekusiyanisa, kusvotwa, kuhotsira, kurutsa, kuruma, kana mikoko inogona kuitika.
• Kana iwe uine allergies inozivikanwa yekusiyanisa asi uchida iyo kuti ubudirire bvunzo, unogona kugamuchira antihistamines (senge Benadryl) kana steroids pamberi pekuyedzwa.

Itsvo dzinobatsira kusefa iodini kubva mumuviri. Kana iwe uine chirwere cheitsvo kana chirwere cheshuga, unofanirwa kutariswa zvakanyanya kumatambudziko eitsvo mushure mekupatsanurwa. Kana iwe uine chirwere cheshuga kana uine chirwere cheitsvo, taura nemupi wako usati waedzwa kuti uzive njodzi dzako.

Usati wagamuchira musiyano, udza mupi wako kana iwe ukatora mushonga weshuga metformin (Glucophage) nekuti ungangoda kutora matanho ekuwedzera. Ungangoda kumisa mushonga kwemaawa makumi mana nemasere mushure mekuedzwa.

Muzviitiko zvisingawanzoitiki, dhayi rinogona kukonzera kutyisidzira kwehupenyu mhinduro inonzi anaphylaxis. Kana iwe uine chero chinetso chekufema panguva yekuyedzwa, udza iyo scanner opareta ipapo ipapo. Scanners inouya neintakcom uye masipika, kuti munhu anokwanisa kukunzwa nguva dzose.
