I-CT scan (computed tomography) luvavanyo lokujonga imifanekiso olunceda ababoneleli bezempilo ukuba babone izifo kunye nokwenzakala. Isebenzisa uthotho lwee-X-ray kunye neekhompyutha ukwenza imifanekiso eneenkcukacha zamathambo kunye nezicubu ezithambileyo. I-CT scans ayinabuhlungu kwaye ayingenisi ntlungu. Ungaya esibhedlele okanye kwiziko lokujonga imifanekiso ukuze ufumane i-CT scan ngenxa yohlobo oluthile lokugula. Eli nqaku liza kukwazisa nge-CT scan ngokweenkcukacha.
Yintoni i-CT scan?
I-CT (computed tomography) iskeni luvavanyo lokuthatha imifanekiso. Njenge-X-ray, inokubonisa izakhiwo emzimbeni wakho. Kodwa endaweni yokwenza imifanekiso ethe tyaba ye-2D, ii-CT scans zithatha amashumi ukuya kumakhulu emifanekiso yomzimba. Ukuze ufumane le mifanekiso, i-CT iya kuthatha ii-X-ray njengoko ijikeleza kuwe.
Ababoneleli bezempilo basebenzisa ii-CT scans ukuze babone ukuba zeziphi ii-X-ray eziqhelekileyo ezingenakuboniswa. Umzekelo, izakhiwo zomzimba ziyadibana kwii-X-ray eziqhelekileyo, kwaye izinto ezininzi azibonakali. I-CT ibonisa ulwazi oluneenkcukacha malunga nelungu ngalinye ukuze kubonakale ngokucacileyo nangokuchaneke ngakumbi.
Elinye igama le-CT scan yi-CAT scan. I-CT imele “i-computed Tomography,” ngelixa i-CAT imele “i-computed axial tomography.” Kodwa la magama mabini achaza uvavanyo olufanayo lomfanekiso.
I-CT scan ibonisa ntoni?
I-CT scan ithatha imifanekiso yakho:
Amathambo.
Izihlunu.
Amalungu omzimba.
Ivazi yegazi.
Yintoni enokufunyanwa zii-CT scans?
Ii-CT scans zinceda ababoneleli beenkonzo zonyango ukuba babone ukwenzakala nezifo ezahlukeneyo, kuquka:
Iintlobo ezithile zomhlaza kunye neethumba ezingengomhlaza (ezingengomhlaza).
Amathambo aphukileyo (aphukileyo).
Isifo sentliziyo.
Amahlwili egazi.
Iingxaki zamathumbu (i-appendicitis, i-diverticulitis, ukuvaleka kwamathumbu, isifo sikaCrohn).
Amatye ezintso.
Ukulimala kwengqondo.
Ukulimala komqolo.
Ukopha ngaphakathi.
Ukulungiselela i-CT scan
Nazi ezinye izikhokelo ngokubanzi:
Cwangcisa ukufika kwangethuba. Ugqirha wakho uza kukuxelela ukuba uza kuqhubeka nini ne-aphoyintimenti yakho.
l Musa ukutya iiyure ezine ngaphambi kokuba uhlolwe nge-CT.
Sela kuphela izinto ezicacileyo (ezifana namanzi, ijusi, okanye iti) kwiiyure ezimbini ngaphambi kokuba udibane nogqirha.
Nxiba impahla ekhululekileyo kwaye ukhulule naziphi na izacholo zesinyithi okanye impahla (qaphela ukuba nantoni na enesinyithi ayivumelekanga!). Umongikazi angakunika ilokhwe yesibhedlele.
Ugqirha wakho angasebenzisa izinto ezibonisa umahluko ukuze abonise iindawo ezithile zomzimba wakho kwiskena. Kwiskena se-CT esibonisa umahluko, umqhubi uza kufaka i-IV (i-catheter efakwa kwi-intravenous) aze afake i-contrast medium (okanye idayi) emthanjeni wakho. Banokukunika into enokuselwa (njenge-barium swallow) ukuze iphume emathunjini akho. Zombini zinokuphucula ukubonakala kwezicubu ezithile, amalungu omzimba okanye imithambo yegazi kwaye zincede ababoneleli bezempilo ukuba bafumanise iimeko ezahlukeneyo zonyango. Xa uchama, izinto ezibonisa umahluko emithanjeni zihlala zikhutshwa emzimbeni wakho kwiiyure ezingama-24.
Nazi ezinye iingcebiso zokulungiselela i-CT contrast scan:
Uvavanyo lwegazi: Usenokufuna uvavanyo lwegazi ngaphambi kokuba ucwangcise i-CT scan. Oku kuya kunceda umboneleli wakho wezempilo aqinisekise ukuba i-contrast medium ikhuselekile ukuyisebenzisa.
Imiqathango yokutya: Kuya kufuneka uqaphele ukutya kwakho kwiiyure ezine ngaphambi kokuba uskene i-CT. Ukusela ulwelo olucacileyo kuphela kunokunceda ukuthintela isicaphucaphu ngelixa ufumana i-contrast media. Ungasela umhluzi, iti okanye ikofu emnyama, ijusi ehluziweyo, i-gelatin ecacileyo, kunye neziselo ezibandayo ezicacileyo.
Amayeza e-Allergy: Ukuba une-allergy kwi-contrast medium esetyenziselwa i-CT (equlethe i-iodine), kunokufuneka uthathe ii-steroids kunye nee-antihistamines ngobusuku bangaphambi nangentsasa yotyando. Qiniseka ukuba ujongana nomboneleli wakho wezempilo kwaye umcele ukuba aku-odolele la mayeza ukuba kuyimfuneko. (Ii-contrast agents ze-MRI kunye ne-CT zahlukile. Ukuba ne-allergy kwi-contrast agent enye akuthethi ukuba une-allergy kwenye.)
Ukulungiselela Isisombululo: Isisombululo se-contrast media somlomo kufuneka sisetyenziswe kanye njengoko kuyalelwe.
Imisebenzi ethile kwi-CT scan
Ngexesha lovavanyo, isigulane sidla ngokulala ngomqolo etafileni (njengebhedi). Ukuba uvavanyo lwesigulane lufuna oko, umboneleli wezempilo unokufaka idayi yokwahlulahlula ngemithambo yegazi (emthanjeni wesigulane). Idayi inokubangela ukuba izigulane zizive zimanzi okanye zibe nencasa yesinyithi emlonyeni wazo.
Xa iskena siqala:
Ibhedi yangena kancinci kancinci kwiskena. Ngeli xesha, imilo yedonathi kufuneka ihlale ithule kangangoko, njengoko intshukumo iya kuwenza umfanekiso ube mfiliba.
Ezifana nedonati zinokucelwa ukuba zibambe umphefumlo wazo okwethutyana, ngesiqhelo zingaphantsi kwemizuzwana eli-15 ukuya kwengama-20.
Iskena sithatha umfanekiso omile okwedonathi wendawo ekufuneka ibonwe ngababoneleli bezempilo. Ngokungafaniyo neskena ze-MRI (i-magnetic resonance imaging scans), ii-CT scans azithethi.
Emva kokuba uhlolo lugqityiwe, ibhentshi yokusebenzela ibuyela umva ngaphandle kwesikena.
Ubude be-CT scan
I-CT scan idla ngokuthatha malunga neyure. Uninzi lwexesha lukulungiselela. I-scan ngokwayo ithatha ngaphantsi kwemizuzu eli-10 okanye eli-15. Ungaqhubeka nemisebenzi eqhelekileyo emva kokuba umboneleli wakho wezempilo evumile - ngesiqhelo emva kokuba begqibile ukuskena kwaye baqinisekise ukuba umgangatho womfanekiso ulungile.
Iziphumo ebezingalindelekanga ze-CT scan
I-CT scan ngokwayo ayidli ngokubangela iziphumo ebezingalindelekanga. Kodwa abanye abantu bafumana iziphumo ebezingalindelekanga ezingephi ezivela kwi-contrast agent. Ezi ziphumo bezingalindelekanga zinokubandakanya isicaphucaphu nokuhlanza, intloko ebuhlungu, kunye nesiyezi.
