Ngaba uceliwe ukuba wenze i-CT scan (i-Computed Tomography)? Ungakhathazeki, siza kuthetha ngale nto ngokweenkcukacha!

Xa ugqirha ekuxelela ukuba wenze i-CT scan (i-Computed Tomography), usenokuba noloyiko kwaye unomdla, akunjalo? Kuqhelekile ukuba kuvele imibuzo efana nokuthi "Yintoni? Ingaba iza kuba buhlungu? Kutheni isenziwa?" engqondweni. Ke namhlanje, siza kuthetha ngokuba yintoni i-CT scan, kwenzeka ntoni ngayo, kunye nendlela esifanele siyilungiselele ngayo ngendlela elula neqondakalayo.

Yintoni kanye kanye i-CT scan?

Ngamafutshane, i-CT scan ifana ne-X-reyi, kwaye isetyenziselwa ukujonga ngaphakathi emzimbeni wakho. Nangona kunjalo, i-X-reyi eqhelekileyo ikunika umfanekiso othe tyaba othathwe kwicala elinye. Kwi-CT scan, umatshini okhethekileyo ujikeleza ujikeleze wena kwaye uthatha amakhulu eemifanekiso ze-X-reyi kwiikona ezahlukeneyo. Emva koko ikhompyutha idibanisa yonke le mifanekiso ukwenza umbono oneemilinganiselo ezintathu (3D) womzimba wakho, kuquka amalungu omzimba kunye namathambo.

Khawucinge nje, ukuba ujonga isifuba nge-X-ray eqhelekileyo, izinto ezifana nemiphunga nentliziyo zibonakala ngathi zigqunyiwe zonke. Kodwa nge-CT scan, ungabona ngalinye lala malungu ngokwahlukeneyo nangokucacileyo. Abanye abantu bakubiza oku ngokuba yi-CAT scan. I-CT imele i-`(Computed Tomography)`, kwaye i-CAT imele i-`(Computed Axial Tomography)`. Nokuba yeyiphi na indlela, ezi zivavanyo ezifanayo.

Yintoni esinokuyibona nge-CT scan?

I-CT scan ingabona ngokucacileyo la malungu omzimba wakho alandelayo:

• Amathambo (amathambo)
• Izihlunu
• Izitho zangaphakathi (ezifana nemiphunga, intliziyo, isibindi, izintso)
• Imithambo yegazi (imithambo yegazi)

Zeziphi izifo ezinokuthi i-CT scan incede ekuxilongweni kwazo?

Ii-CT scan ziluncedo kakhulu koogqirha ekuxilongeni izifo ezahlukeneyo kunye nokwenzakala. Nazi imizekelo embalwa:

• Ezinye iintlobo zomhlaza kunye nezimila ezingezizo zomhlaza (ii-Benign tumors)
• Ukuqhekeka kwamathambo (amathambo aphukileyo, ukukruneka)
• Isifo sentliziyo
• Amahlwili egazi
• Izifo zamathumbu (umz., `(Appendicitis)`, `(Diverticulitis)`, ukuvaleka kwamathumbu, `(isifo sikaCrohn)`)
• Amatye ezintso
• Ukwenzakala engqondweni (njengokwenzakala entloko)
• Ukulimala komqolo (ukulimala komqolo)
• Ukopha ngaphakathi

Khawuthelekelele ukuba ngequbuliso uyawa uze ubetheke entloko ngamandla. Emva koko ugqirha usenokufuna ukwazi ukuba kukho na ukopha okanye ukudumba entlokweni. Kulapho ke i-CT scan iba yinto ebaluleke kakhulu.

Sifanele sizilungiselele njani ngaphambi kokuba sihlolwe nge-CT?

Ugqirha wakho uza kukuchazela yonke into ekufuneka uyazi ngaphambi kokuba wenze i-CT scan, kodwa nantsi into edla ngokwenzeka:

• Cwangcisa ukufika kwangethuba kunexesha olicwangcisiweyo. Ugqirha uza kukuxelela ukuba uza kufika ngaliphi ixesha.
• Kwi-CT scanMusa ukutya nantoni na iiyure ezine ngaphambi kokuba utye.
• Sela kuphela ulwelo olucacileyo olufana namanzi, iti, kunye nejusi yeziqhamo (ehluziweyo) kangangeeyure ezimbini ngaphambi kokuba uhlolwe.
• Nxiba impahla ekhululekileyo. Susa ubucwebe besinyithi (ezifana namacici, imigexo, imisesane) kunye nempahla enesinyithi. Isibhedlele singakunika impahla ekhethekileyo yokunxiba.

Yintoni i-CT scan ene-contrast? (I-CT Scan ene-Contrast)

Ngamanye amaxesha, ulwelo olukhethekileyo (njengonyango) lusetyenziswa ukwenza iindawo ezithile zomzimba, amalungu omzimba, okanye imithambo yegazi zibonakale ngokucacileyo kwi-CT scan. Oku kubizwa ngokuba yi -`(Contrast material)` . Lunokunikwa ngeendlela ezimbini:

1. I-Intravenous (IV): Olu lwelo lufakwa emthanjeni nge-cannula, njenge-saline.

2. Umahluko womlomo: Ngamanye amaxesha, ingakumbi xa uhlola iindawo zomzimba ezifana namathumbu, unikwa ulwelo ukuba ulusele (umzekelo, i-barium swallow).

Le `(Izinto ezibonisa umahluko)` ivumela oogqirha ukuba babone izicwili ezithile, amalungu omzimba, kunye nemithambo yegazi ngokucacileyo. Kwenza kube lula ukufumanisa izifo. `(I-IV contrast)`, enikwa ngemithambo yegazi, idla ngokukhutshwa emzimbeni xa uchama kwiiyure ezingama-24.

Amalungiselelo ongezelelweyo e-CT kunye nomahluko:

Ukuba wenza i-CT scan usebenzisa izinto ezibonisa umahluko, kuya kufuneka uqaphele ezinye izinto ezimbalwa ezongezelelweyo:

• Uvavanyo lwegazi: Usenokucelwa ukuba wenze uvavanyo lwegazi ngaphambi kokuba uskene nge-CT. Qinisekisa ukuba ugqirha wakho uyazi ukuba kukhuselekile na ukuba nezinto zokulinganisa umbala.
• Imiqathango yokutya neziselo: Ukuze uthintele isicaphucaphu nokuhlanza ngelixa kunikwa izinto ezichaseneyo, uya kucelwa ukuba usele ulwelo olucacileyo kuphela iiyure ezine ngaphambi kokuba uskeniwe. Imizekelo: umhluzi wesuphu (ongenawo amafutha), iti (eluhlaza kuphela), ikofu (engenalo ubisi neswekile), ijusi yeziqhamo ehluziweyo kakuhle, igelatin, kunye nezinye iziselo ezicacileyo nezineswekile (ezifana ne-ginger ale).
• Amayeza e-Allergy: Ukuba une-allergy kwizinto ezisetyenziswa kwi-CT scan (equlethe i-iodine), oko kukuthi, ukuba ukhe waba ne-allergy kwinto efanayo ngaphambili, ugqirha wakho unokukunika amayeza akhethekileyo (afana nee-steroids kunye nee-antihistamines) oza kuwathatha ngobusuku bangaphambi kwe-scan kunye nentsasa ye-scan. Kufuneka uthethe nogqirha wakho ngale nto kwaye ufumane i-prescription yabo. (Kukho iintlobo ezimbini zee-contrast agents ezisetyenziswa kwi-MRI scans kunye nenye esetyenziswa kwi-CT scans. Ukuba ne-allergy kwenye akuthethi ukuba une-allergy kwenye.)
• Ulwelo lokwahlulahlula: Ukuba unikwa ulwelo lokwahlulahlula , kufuneka ulusele kanye njengoko ugqirha ekuxelela, nangexesha oxelelwe ngalo.

Kwenzeka ntoni ngexesha le-CT scan?

Ngexesha lovavanyo, uhlala ulala phantsi kwindawo efana nebhedi (`(Itafile)`). Ukuba uvavanyo lwakho lufuna `(Izinto ezibonisa umahluko)`, umsebenzi wezempilo uza kuyifaka emthanjeni wakho. Xa olu `(umahluko)` lunikwa, abanye abantuUsenokuziva ubushushu obuncinci okanye incasa yesinyithi emlonyeni wakho. Oku kuqhelekile, ungakhathazeki.

Xa iskena siqala, nantsi into eyenzekayo:

• Umatshini omkhulu omile okwedonathi (`(isikena esimile okwedonathi)`) ungena ebhedini okuyo.
• Ngeli xesha, kufuneka uhlale uzolile kangangoko unako, njengoko ukuhambahamba kunokubangela ukuba imifanekiso ingacaci.
• Ngamanye amaxesha uya kucelwa ukuba ubambe umphefumlo wakho okwethutyana, ngesiqhelo okwethutyana elifutshane, njengemizuzwana eli-15-20.
• Umatshini uthatha imifanekiso yelungu lomzimba ugqirha afuna ukulibona. Ngokungafaniyo ne-MRI scan (Magnetic Resonance Imaging scan), i-CT scan ayikhiphi ngxolo ingako, ithule.
• Xa uvavanyo lugqityiwe, ibhedi iyabuya iphuma ematshinini.

Ithatha ixesha elingakanani i-CT scan?

I-CT scan idla ngokuthatha malunga neyure. Kodwa uninzi lwelo xesha luchithwa lulungiselela. I-scan ngokwayo ithatha ngaphantsi kwemizuzu eli-10 okanye eli-15. Nje ukuba ugqirha akunike imvume - oko kuthetha ukuba emva kokuba i-scan igqityiwe kwaye imifanekiso ikwimeko entle - ungaqhubeka nomsebenzi wakho wesiqhelo.

Ngaba kukho naziphi na iziphumo ebezingalindelekanga ezivela kwi-CT scan?

I-CT scan ngokwayo ayidli ngokubangela iziphumo ebezingalindelekanga ezinkulu. Nangona kunjalo, abanye abantu banokufumana iziphumo ebezingalindelekanga ezincinci kwizinto ezibonisa umahluko. Umzekelo:

• Isicaphucaphu nokuhlanza
• Intloko ebuhlungu
• Isiyezi

Ezi zinto zihlala zisiba ngcono emva kwexesha elithile.

Siza kuzazi nini iziphumo ze-CT scan?

Kudla ngokuthatha phakathi kweeyure ezingama-24 ukuya kwezingama-48 ukufumana iziphumo ze-CT scan yakho. Ingcali ye-radiology (ugqirha ogxile kwi-CT scans kunye nezinye ii-X-rays) uya kujonga imifanekiso yakho ye-scan aze abhale ingxelo malunga noko bakufumanisileyo. Nangona kunjalo, kwimeko kaxakeka, njengasesibhedlele okanye kwigumbi likaxakeka, oogqirha banokuzifumana iziphumo kwiyure nje enye.

Emva kokuba ingcali ye-radiology kunye nogqirha wakho behlole iziphumo, baya kukunika elinye idinga okanye bakubize ukuze baxoxe ngeenkcukacha.

Ngaba i-CT scan ikhuselekile?

Oogqirha bathi ii-CT scans zikhuselekile kakhulu . Ii-CT scans zikhuselekile nakubantwana abancinci. Xa zenziwe ebantwaneni, oogqirha bayayinciphisa idosi ukuze banciphise ubungakanani bemitha abachatshazelwa kuyo.

Njengee-X-reyi, ii-CT scans zisebenzisa ubungakanani obuncinci bemitha ye-ionizing ukuthatha imifanekiso. Nazi ezinye zeengozi ezinxulumene nale mitha:

• Umngcipheko womhlaza:Uvavanyo olusebenzisa imitha, njengee-X-ray kunye nee-CT scans, ngokwethiyori lunokunyusa umngcipheko wokuba nomhlaza ngenani elincinci kakhulu. Kodwa umahluko mncinane kakhulu kangangokuba kunzima ukuwulinganisa ngokuchanekileyo.
• Iimpendulo ze-Allergic: Ngamanye amaxesha, unokuba ne-allergic reaction kwizinto ezichaseneyo. Oku kunokuba yinto encinci okanye kube yinto enzulu. Yiyo loo nto sibuza ukuba ngaba ukhe waba ne-allergy ngaphambili.

Ukuba unemibuzo okanye iinkxalabo malunga neengozi zempilo zokwenziwa kwe-CT scan, thetha nogqirha wakho ngayo ngokukhululekileyo. Banokukuchazela ngayo baze bakuncede wenze isigqibo esinolwazi.

Ndingayifumana i-CT scan ukuba ndikhulelwe?

Ukuba ukhulelwe, okanye ucinga ukuba ukhulelwe, ngokuqinisekileyo kufuneka uxelele ugqirha wakho. Ii-CT scans ze-pelvis yakho kunye nesisu sakho zinokubeka umntwana wakho ongekazalwa kwi-radiation ethile. Nangona kunjalo, ubungakanani abuhlali bukhulu ngokwaneleyo ukuba bungalimaza umntwana. Kwakhona, ii-CT scans zezinye iindawo zomzimba wakho (umz., intloko, isifuba) azibeki mngcipheko kumntwana ongekazalwa. Nangona kunjalo, kungcono ukuthetha nogqirha wakho ngale nto kwaye ufumane ingcebiso.

Okokugqibela, izinto ezimbalwa ekufuneka uzikhumbule (Umyalezo Wokuya Ekhaya)

Kuqhelekile ukuba novalo kwaye uxhalabe kancinci xa ugqirha wakho ekuxelela ukuba wenze i-CT scan (i-Computed Tomography). Kodwa khumbula, i-CT scan yile:

• Uvavanyo olungenabuhlungu.
• Umngcipheko uphantsi kakhulu.
• Iluncedo kakhulu koogqirha ekuxilongeni izifo ezahlukeneyo.
