I-CT (i-computed tomography) i-scan luvavanyo lokucinga olunceda ababoneleli bezempilo babone izifo kunye nokulimala. Isebenzisa uthotho lwee-X-reyi kunye neekhompyuter ukwenza imifanekiso eneenkcukacha yamathambo kunye nezicubu ezithambileyo. I-CT scans ayinabuhlungu kwaye ayinayo invasive. Ungaya esibhedlele okanye kwiziko lokucinga nge-CT scan ngenxa yohlobo oluthile lwesigulo. Eli nqaku liza kukwazisa kwi-CT scanning ngokweenkcukacha.
Yintoni i-CT scan?
I-CT (i-computed tomography) iskena luvavanyo lomfanekiso. Kanye njengeX-reyi, inokubonisa ubume bomzimba wakho. Kodwa endaweni yokwenza imifanekiso ecaba ye-2D, i-CT scan ithatha amashumi ukuya kumakhulu emifanekiso yomzimba. Ukufumana le mifanekiso, i-CT iya kuthatha ii-X-reyi njengoko ijikeleza kuwe.
Ababoneleli ngezempilo basebenzisa ii-CT scans ukubona ukuba zeziphi ii-X-reyi eziqhelekileyo ezingenakubonisa. Umzekelo, izakhiwo zomzimba ziyadibana kwiiX-reyi eziqhelekileyo, kwaye izinto ezininzi azibonakali. I-CT ibonisa ulwazi oluneenkcukacha malunga nelungu ngalinye ukwenzela ukujonga okucacileyo, okuchanekileyo.
Elinye igama le-CT scan yi-CAT scan. I-CT imele “icomputed Tomography,” ngoxa i-CAT imele “icomputed axial tomography.” Kodwa la magama mabini achaza uvavanyo olufanayo lokucinga.
I-CT scan ibonisa ntoni?
I-CT scan ithatha imifanekiso yakho:
Amathambo.
Izihlunu.
Amalungu.
Ivazi yegazi.
Yintoni enokubonwa yi-CT scans?
I-CT scans inceda ababoneleli bezempilo ukuba babone ukwenzakala kunye nezifo ezahlukeneyo, kubandakanya:
Iintlobo ezithile zomhlaza kunye ne-benign (ezingenawo umhlaza) ithumba.
Ukuqhekeka (amathambo aphukileyo).
Isifo sentliziyo.
Amahlwili egazi.
Ukuphazamiseka kwamathumbu (appendicitis, diverticulitis, blockages, isifo sikaCrohn).
Amatye ezintso.
Ukulimala kwengqondo.
Ukulimala komqolo.
Ukopha kwangaphakathi.
Ukulungiselela i-ct scan
Nazi izikhokelo ngokubanzi:
l Cwangcisa ukufika kwangethuba. Ugqirha wakho uya kukuxelela ukuba uyigcine nini idinga lakho.
l Ungatyi iiyure ezine phambi kwe-CT scan yakho.
l Sela kuphela ulwelo olucacileyo (njengamanzi, ijusi, okanye iti) kwiiyure ezimbini phambi kwedinga lakho.
l Nxiba iimpahla ezikhululekile kwaye ususe nayiphi na intsimbi yentsimbi okanye impahla (qaphela ukuba nantoni na equkethe isinyithi ayivumelekanga!). Umongikazi unokubonelela ngengubo yasesibhedlele.
Ugqirha wakho unokusebenzisa izinto ezichaseneyo ukugqamisa iindawo ezithile zomzimba wakho kwiskeni. Kwi-CT scan, umqhubi uya kubeka i-IV (i-catheter ye-intravenous) kwaye atofe umahluko (okanye idayi) kumthambo wakho. Basenokukunika into eselwayo (efana ne-barium swallow) ukukhupha amathumbu akho. Bobabini banokuphucula ukubonakala kwezicubu ezithile, izitho okanye imithambo yegazi kunye nokunceda ababoneleli bezempilo baxilonge iimeko ezahlukeneyo zonyango. Xa uchama, imathiriyeli yokuchasana emithanjeni ihlala igungxulwa kwisixokelelwano sakho kwiiyure ezingama-24.
Okulandelayo zezinye iingcebiso ezongezelelweyo zolungiselelo lwe-CT scan scan:
Uvavanyo lwegazi: Unokufuna uvavanyo lwegazi phambi kwe-CT scan yakho ecwangcisiweyo. Oku kuya kunceda umboneleli wakho wezempilo aqinisekise ukuba indlela yokuchasana ikhuselekile ukuyisebenzisa.
Izithintelo zokutya: Kuya kufuneka ukuba ubukele ukutya kwakho kwiiyure ezine phambi kwe-CT scan yakho. Ukusela ulwelo olucacileyo kuphela kunokuthintela isicaphucaphu ngelixa ufumana imidiya eyahlukileyo. Unokuba nomhluzi, itiye okanye ikhofi emnyama, ijusi ehluziweyo, i-gelatin ecacileyo, kunye neziphuzo ezithambileyo ezicacileyo.
Amayeza okungezwani komzimba: Ukuba awuhambisani nesixhobo sokuchasana esisetyenziselwa i-CT (equlethe i-iodine), unokufuna ukuthatha i-steroids kunye ne-antihistamines ngobusuku bangaphambili kunye nentsasa yotyando. Qinisekisa ukuba ujongana nomboneleli wakho wezempilo kwaye ubacele ukuba baku-odole la mayeza ukuba ayafuneka. (Ii-agent ezichaseneyo ze-MRI kunye ne-CT zahlukile. Ukungadibani ne-agent enye ayithethi ukuba uyala kwenye.)
Ukulungiselela Isisombululo: Isisombululo semidiya yokuchasana ngomlomo kufuneka sisetyenziswe ngokuchanekileyo njengoko kuyalelwe.
Imisebenzi ethile kwi-CT scan
Ngexesha lovavanyo, isigulane ngokuqhelekileyo silala ngomqolo phezu kwetafile (efana nebhedi). Ukuba ngaba uvavanyo lwesigulana luyayifuna, umboneleli wezempilo unokutofa idayi yokuchasana ngemithambo (kwimithambo yesigulana). Idayi inokubangela ukuba izigulana zizive zigungxulwe okanye zibe nencasa yesinyithi emlonyeni.
Xa iskena siqala:
Ibhedi ithe chu ukuya kwi scanner. Ngeli xesha, ukumila kwe-donut kufuneka kuhlale kuthe cwaka njengoko kunokwenzeka, njengoko intshukumo iya kuphazamisa umfanekiso.
Abo bamile okwedonathi basenokucelwa ukuba babambe umphefumlo ixeshana elifutshane, ngokuqhelekileyo ngaphantsi kwemizuzwana eli-15 ukuya kwengama-20.
Iskena sithatha umfanekiso omile okwedonathi wendawo ekufuneka ababoneleli bezempilo bayibone. Ngokungafaniyo ne-MRI scans (i-magnetic resonance imaging scans), i-CT scan ayithethi.
Emva kokuba uhlolo lugqityiwe, indawo yokusebenza ibuyela umva ngaphandle kweskena.
CT scan ubude
I-CT scan idla ngokuthatha malunga neyure. Ixesha elininzi kukulungiselela. Ukuskena ngokwayo kuthatha ngaphantsi kwe-10 okanye imizuzu eyi-15. Unokuphinda uqalise imisebenzi eqhelekileyo emva kokuba umboneleli wakho wezempilo evumile - ngokuqhelekileyo emva kokuba begqibile ukuskena kwaye baqinisekise ukuba umgangatho womfanekiso ulungile.
CT scan iziphumo ebezingalindelekanga
I-CT scan ngokwayo ayibangeli iziphumo ebezingalindelekanga. Kodwa abanye abantu bafumana iziphumo ebezingalindelekanga ezingephi ukusuka kwiarhente yokuchasana. Ezi ziphumo bezingalindelekanga zinokubandakanya isicaphucaphu kunye nokugabha, intloko ebuhlungu, kunye nesiyezi.

Malunga ne-LnkMed:
Ukususela ekusekweni kwayo,LnkMedibigxile kwibala leii-ejenti zokuchasa ngoxinzelelo oluphezulu. Iqela lobunjineli be-LnkMed likhokelwa yi-Ph.D. uneminyaka engaphezu kweshumi yamava kwaye uzibandakanye nzulu kuphando nophuhliso. Phantsi kokhokelo lwakhe, iCT isitofu sentloko enye, CT isitofu sentloko kabini, Isitofu se-agent ye-MRI yokuchasana, kwayeI-Angiography yoxinzelelo oluphezulu lwe-ejenti yokuchasaziyilwe ngezi mpawu: umzimba owomeleleyo noxineneyo, ujongano olufanelekileyo nolukrelekrele lokusebenza, imisebenzi epheleleyo, ukhuseleko oluphezulu, kunye noyilo oluhlala ixesha elide. Sinokubonelela ngeesirinji kunye netyhubhu ehambelana nezo mpawu zidumileyo ze-CT, iMRI, ii-injection ze-DSA Ngesimo sabo sengqondo esinyanisekileyo kunye namandla obuchwephesha, bonke abasebenzi be-LnkMed bayakumema ngokunyanisekileyo ukuba uze uhlolisise iimarike ezininzi kunye.
