Kujambula kwa CT (computed tomography) ndi njira yojambulira zithunzi yomwe imathandiza ogwira ntchito zachipatala kuzindikira matenda ndi kuvulala. Imagwiritsa ntchito X-ray ndi makompyuta angapo kuti apange zithunzi zatsatanetsatane za mafupa ndi minofu yofewa. Kujambula kwa CT sikupweteka komanso sikuvulaza. Mutha kupita kuchipatala kapena ku malo ojambulira zithunzi kuti mukachite CT scan chifukwa cha matenda enaake. Nkhaniyi ikudziwitsani mwatsatanetsatane za CT scanning.
Kodi CT scan ndi chiyani?
Kujambula kwa CT (computed tomography) ndi kuyesa kujambula. Monga momwe X-ray imachitira, imatha kuwonetsa kapangidwe ka thupi lanu. Koma m'malo mopanga zithunzi za 2D, CT scan imatenga zithunzi zambirimbiri za thupi. Kuti mupeze zithunzi izi, CT imatenga X-ray pamene ikuzungulirani.
Ogwira ntchito zachipatala amagwiritsa ntchito ma CT scan kuti aone zomwe ma X-ray achizolowezi sangawonetse. Mwachitsanzo, kapangidwe ka thupi kamafanana pa ma X-ray achizolowezi, ndipo zinthu zambiri sizimawoneka. CT imawonetsa zambiri zokhudza chiwalo chilichonse kuti chiwoneke bwino komanso molondola.
Mawu ena a CT scan ndi CAT scan. CT imayimira “computed Tomography,” pomwe CAT imayimira “computed axial tomography.” Koma mawu awiriwa amafotokoza mayeso ofanana a kujambula zithunzi.
Kodi CT scan imasonyeza chiyani?
Kujambula kwa CT kumatenga zithunzi za matenda anu:
Mafupa.
Minofu.
Ziwalo.
Mitsempha ya magazi.
Kodi ma CT scans angazindikire chiyani?
Kujambula kwa CT kumathandiza ogwira ntchito zachipatala kuzindikira kuvulala ndi matenda osiyanasiyana, kuphatikizapo:
Mitundu ina ya khansa ndi zotupa zosaopsa (zosakhala khansa).
Kusweka kwa mafupa (mafupa osweka).
Matenda a mtima.
Magazi amaundana.
Matenda am'mimba (appendicitis, diverticulitis, blockages, matenda a Crohn).
Miyala ya impso.
Kuvulala muubongo.
Kuvulala kwa msana.
Kutuluka magazi mkati.
Kukonzekera kujambulidwa ndi ct scan
Nazi malangizo ena ambiri:
Konzani kufika msanga. Dokotala wanu adzakuuzani nthawi yoti mukwaniritse nthawi yanu yokumana ndi dokotala.
Musadye kwa maola anayi musanayese CT scan.
Imwani zakumwa zoyera zokha (monga madzi, madzi a zipatso, kapena tiyi) maola awiri musanayambe ulendo wanu.
Valani zovala zabwino ndipo vulani zodzikongoletsera kapena zovala zachitsulo (dziwani kuti chilichonse chokhala ndi chitsulo sichiloledwa!). Namwino angapereke chovala cha kuchipatala.
Dokotala wanu angagwiritse ntchito zinthu zosiyanitsa kuti awonetse madera ena a thupi lanu pa scan. Pa contrast CT scan, dokotalayo adzayika IV (intravenous catheter) ndikubaya contrast medium (kapena utoto) mumtsempha wanu. Angakupatseninso chinthu chomwe mungamwe (monga barium swallow) kuti chituluke m'matumbo mwanu. Zonsezi zingathandize kuti minofu, ziwalo kapena mitsempha yamagazi ziwoneke bwino komanso kuthandiza opereka chithandizo chamankhwala kuzindikira matenda osiyanasiyana. Mukakodza, contrast measurement nthawi zambiri imachotsedwa m'thupi lanu mkati mwa maola 24.
Nazi malingaliro ena okonzekera CT contrast scan:
Kuyezetsa magazi: Mungafunike kuyezetsa magazi musanachite CT scan. Izi zithandiza dokotala wanu kuonetsetsa kuti contrast medium ndi yotetezeka kugwiritsa ntchito.
Zoletsa zakudya: Muyenera kusamala ndi zakudya zanu maola anayi musanagwiritse ntchito CT scan. Kumwa zakumwa zoyera zokha kungathandize kupewa nseru pamene mukulandira mankhwala otsutsana ndi khungu. Mutha kumwa msuzi, tiyi kapena khofi wakuda, madzi osefedwa, gelatin wamba, ndi zakumwa zoziziritsa kukhosi zoyera.
Mankhwala a ziwengo: Ngati muli ndi ziwengo ndi mankhwala oyeretsera khungu omwe amagwiritsidwa ntchito pa CT (omwe ali ndi ayodini), mungafunike kumwa mankhwala a steroid ndi antihistamines usiku watha komanso m'mawa wa opaleshoni. Onetsetsani kuti mwafunsana ndi dokotala wanu kuti akuyitanitsani mankhwala awa ngati pakufunika kutero. (Ma mankhwala oyeretsera khungu a MRI ndi CT ndi osiyana. Kukhala ndi ziwengo ndi mankhwala oyeretsera khungu limodzi sikutanthauza kuti muli ndi ziwengo ndi ena.)
Kukonzekera Yankho: Mankhwala oletsa kusiyanitsa ayenera kumwedwa monga momwe zalembedwera.
Ntchito zapadera mu CT scan
Pa nthawi yoyezetsa, wodwalayo nthawi zambiri amagona chagada patebulo (monga pabedi). Ngati mayeso a wodwalayo akufunika, dokotala akhoza kubaya utoto wosiyana m'mitsempha ya wodwalayo. Utotowo ukhoza kupangitsa odwala kumva ngati atuluka madzi kapena kukhala ndi kukoma kwachitsulo mkamwa mwawo.
Pamene scan ikuyamba:
Bedi linalowa pang'onopang'ono mu sikirini. Pa nthawiyi, mawonekedwe a donati ayenera kukhala chete momwe angathere, chifukwa kuyenda kudzasokoneza chithunzicho.
Zooneka ngati donati zingapemphedwenso kuti zigwire mpweya wawo kwa kanthawi kochepa, nthawi zambiri zosakwana masekondi 15 mpaka 20.
Chojambuliracho chimatenga chithunzi chooneka ngati donati cha malo omwe ogwira ntchito zachipatala ayenera kuwona. Mosiyana ndi ma MRI scan (magnetic resonance imaging scans), ma CT scan sachita phokoso.
Pambuyo poyesa, benchi logwirira ntchito limabwerera kunja kwa sikirini.
Kutalika kwa CT scan
Kujambula kwa CT scan nthawi zambiri kumatenga pafupifupi ola limodzi. Nthawi zambiri kumakhala kukonzekera. Kujambula kokha kumatenga mphindi zosakwana 10 kapena 15. Mutha kuyambiranso ntchito zanu zachizolowezi pambuyo poti dokotala wanu wavomereza - nthawi zambiri akamaliza kujambula ndikutsimikiza kuti chithunzi chili bwino.
Zotsatira zoyipa za CT scan
Kujambula kwa CT kokha nthawi zambiri sikubweretsa zotsatirapo zoyipa. Koma anthu ena amakumana ndi zotsatirapo zochepa kuchokera ku mankhwala osiyanitsa. Zotsatirapo izi zingaphatikizepo nseru ndi kusanza, mutu, ndi chizungulire.
