Uke wacelwa ukuthi wenze i-CT scan (i-Computed Tomography)? Ungakhathazeki, sizoxoxa ngalokhu ngokuningiliziwe!

Uma udokotela ekutshela ukuthi wenze i-CT scan (i-Computed Tomography), ungase wesabe kancane futhi ube nelukuluku, akunjalo? Kuvamile ukuthi kuvele imibuzo efana nokuthi "Kuyini? Ingabe kuzobuhlungu? Kungani kwenziwa?" engqondweni. Ngakho-ke namuhla, sizoxoxa ngokuthi kuyini i-CT scan, kwenzekani ngayo, nokuthi kufanele siyilungiselele kanjani ngendlela elula neqondakalayo.

Kuyini ngempela i-CT scan?

Kalula nje, i-CT scan ifana ne-X-ray, futhi isetshenziselwa ukubuka ingaphakathi lomzimba wakho. Kodwa-ke, i-X-ray evamile ikunikeza isithombe esisicaba esithathwe ohlangothini olulodwa. Ku-CT scan, umshini okhethekile ujikeleza nxazonke zakho bese uthatha amakhulu ezithombe ze-X-ray ezivela ezinhlangothini ezahlukene. Ikhompyutha bese ihlanganisa zonke lezi zithombe ukudala umbono womzimba wakho onezinhlangothi ezintathu (3D), okuhlanganisa izitho zomzimba namathambo.

Cabanga nje, uma ubheka i-X-ray yesifuba evamile, izinto ezifana namaphaphu nenhliziyo zibonakala zihambisana. Kodwa nge-CT scan, ungabona ngayinye yalezi zitho ngokwehlukana nangokucacile. Abanye abantu babiza lokhu ngokuthi i-CAT scan. I-CT imele i-`(Computed Tomography)`, kanti i-CAT imele i-`(Computed Axial Tomography)`. Noma ngabe yikuphi, lokhu kuyivivinyo elifanayo.

Yini esingayibona nge-CT scan?

I-CT scan ingabona ngokucacile izingxenye zomzimba wakho ezilandelayo:

• Amathambo (amathambo)
• Imisipha
• Izitho zangaphakathi (njengamaphaphu, inhliziyo, isibindi, izinso)
• Imithambo yegazi (imithambo yegazi)

Yiziphi izinhlobo zezifo ezingasiza ekuxilongweni yi-CT scan?

Ama-CT scan awusizo kakhulu kodokotela ekuxilongeni izifo ezahlukahlukene kanye nokulimala. Nazi izibonelo ezimbalwa:

• Ezinye izinhlobo zomdlavuza kanye nezimila ezingezona umdlavuza (izimila ezingenobungozi)
• Ukuphuka kwamathambo (amathambo aphukile, ukuklwebheka)
• Isifo senhliziyo
• Amahlule egazi
• Izifo zamathumbu (isb., `(Appendicitis)`, `(Diverticulitis)`, ukuvinjelwa kwamathumbu, `(isifo sikaCrohn)`)
• Amatshe ezinso
• Ukulimala ebuchosheni (njengokulimala ekhanda)
• Ukulimala komgogodla (ukulimala komgogodla)
• Ukopha kwangaphakathi

Cabanga ukuthi uvele uwele phansi bese ushaya ikhanda lakho kanzima. Khona-ke udokotela angase afune ukwazi kahle ukuthi kukhona yini ukopha noma ukuvuvukala ekhanda. Yilapho-ke ukuhlolwa kwe-CT kuba yinto ebaluleke kakhulu.

Kufanele sizilungiselele kanjani ngaphambi kokuhlolwa kwe-CT?

Udokotela wakho uzochaza konke okudingeka ukwazi ngaphambi kokuba wenze i-CT scan, kodwa nakhu okuvame ukwenzeka:

• Hlela ukufika kusenesikhathi kunesikhathi osibekiwe. Udokotela uzokutshela ukuthi uzofika nini.
• Ukuze kwenziwe i-CT scanUngadli lutho amahora amane ngaphambi kosuku.
• Phuza kuphela uketshezi olucwengekile njengamanzi, itiye, kanye nejusi yezithelo (ehlungiwe) amahora amabili ngaphambi kokuskena.
• Gqoka izingubo ezikhululekile. Susa ubucwebe bensimbi (njengezindandatho, imigexo, amasongo) kanye nezingubo ezinensimbi. Isibhedlela singase sikunike ingubo ekhethekile ongayigqoka.

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

Ngezinye izikhathi, kusetshenziswa uketshezi olukhethekile (njengomuthi) ukwenza izingxenye ezithile zomzimba, izitho zomzimba, noma imithambo yegazi zibonakale ngokucacile ku-CT scan. Lokhu kubizwa ngokuthi `(Izinto ezihlukile)` . Kunganikezwa ngezindlela ezimbili:

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

2. Ukwehluka komlomo: Ngezinye izikhathi, ikakhulukazi uma uhlola izingxenye zomzimba njengamathumbu, unikezwa uketshezi lokuphuza (isibonelo, i-barium swallow).

Lokhu `(Izinto ezibonisa umehluko)` kuvumela odokotela ukuthi babone izicubu ezithile, izitho zomzimba, kanye nemithambo yegazi ngokucacile. Kwenza kube lula ukuthola izifo. `(I-IV contrast)`, enikezwa ngemithambo yegazi, ivame ukukhishwa emzimbeni uma uchama zingakapheli amahora angama-24.

Amalungiselelo engeziwe e-CT ngokuqhathanisa:

Uma wenza i-CT scan usebenzisa izinto ezibonisa ukuqhathanisa, kuzodingeka wazi izinto ezimbalwa ezengeziwe:

• Ukuhlolwa kwegazi: Ungase ucelwe ukuba uhlolwe igazi ngaphambi kokuskena kwe-CT. Qiniseka ukuthi udokotela wakho uyazi ukuthi kuphephile yini ngawe ukuba nezinto zokuhlukanisa.
• Imikhawulo yokudla neziphuzo: Ukuze uvimbele isicanucanu nokuhlanza ngenkathi kunikezwa izinto zokuhlukanisa, uzocelwa ukuthi uphuze uketshezi olucacile kuphela amahora amane ngaphambi kokuskena. Izibonelo: umhluzi wesobho (ngaphandle kwamafutha), itiye (oluhlaza kuphela), ikhofi (ngaphandle kobisi noshukela), ijusi yezithelo ehlungiwe kahle, i-gelatin, kanye neziphuzo ezithile ezicacile nezinoshukela (njenge-ginger ale).
• Imithi yokungezwani komzimba: Uma une-allergy ezintweni ezisetshenziswa ku-CT scan (equkethe i-iodine), okungukuthi, uma uke waba ne-allergy entweni efanayo esikhathini esidlule, udokotela wakho angakunika imithi ekhethekile (njenge-steroids kanye nama-antihistamine) ongayithatha ngobusuku bangaphambi kokuhlolwa kanye nasekuseni kokuhlolwa. Kufanele ukhulume nodokotela wakho ngalokhu bese uthola incwadi kadokotela. (Kunezinhlobo ezimbili zama-contrast agents asetshenziswa ku-MRI scans kanye nenye esetshenziswa ku-CT scans. Ukuba ne-allergy kwenye akusho ukuthi une-allergy kwenye.)
• Uketshezi oluhlukanisayo: Uma unikezwa uketshezi oluhlukanisayo ukuthi uluphuze , kufanele uluphuze njengoba nje udokotela ekutshelile, nangesikhathi otshelwe ngaso.

Kwenzekani ngesikhathi sokuhlolwa kwe-CT?

Ngesikhathi sokuhlolwa, ngokuvamile uzolala phansi endaweni efana nombhede (`(Ithebula)`). Uma ukuhlolwa kwakho kudinga `(Izinto ezibonisa umehluko)`, isisebenzi sezempilo sizokufaka emthanjeni wakho. Uma lokhu `(Izinto ezibonisa umehluko)` kunikezwa, abanye abantuUngase uzwe umuzwa wokushisa okuncane noma ukunambitheka kwensimbi emlonyeni wakho. Lokhu kuvamile, ungakhathazeki.

Uma ukuskena kuqala, nakhu okwenzekayo:

• Umshini omkhulu omise okwedonathi (`(isikeni esimise okwedonathi)`) ungena embhedeni okuwo.
• Phakathi nalesi sikhathi, kufanele uhlale uthule ngangokunokwenzeka, njengoba ukuhamba kungabangela ukuthi izithombe zingacaci.
• Ngezinye izikhathi uzocelwa ukuba ubambe umoya wakho isikhashana esifushane, ngokuvamile isikhashana esifushane, njengemizuzwana eyi-15-20.
• Umshini uthatha izithombe zengxenye yomzimba udokotela afuna ukuyibona. Ngokungafani ne-MRI scan (Magnetic Resonance Imaging scan), i-CT scan ayibangi umsindo omkhulu, ithule.
• Uma isivivinyo sesiphelile, umbhede uyabuya emshinini.

Kuthatha isikhathi esingakanani ukuhlolwa kwe-CT?

I-CT scan ivame ukuthatha cishe ihora. Kodwa isikhathi esiningi sichithwa silungiselela. I-scan uqobo ithatha imizuzu engaphansi kweyi-10 noma eyi-15. Uma udokotela esekunike imvume - okusho ukuthi ngemva kokuba i-scan isiqediwe futhi izithombe zisezingeni elihle - ungaqala umsebenzi wakho ojwayelekile.

Ingabe kukhona imiphumela emibi evela ku-CT scan?

I-CT scan ngokwayo ayivamisile ukubangela imiphumela emibi emikhulu. Kodwa-ke, abanye abantu bangase babe nemiphumela emibi emincane evela ezintweni ezibonisa ukuqhathanisa. Isibonelo:

• Isicanucanu nokuhlanza
• Ikhanda elibuhlungu
• Isiyezi

Lokhu kuvame ukuba ngcono ngemva kwesikhathi esithile.

Sizoyazi nini imiphumela ye-CT scan?

Ngokuvamile kuthatha amahora angama-24 kuya kwangu-48 ukuthola imiphumela ye-CT scan yakho. Udokotela we-radiologist (udokotela ochwepheshe be-CT scans kanye neminye i-X-ray) uzobheka izithombe zakho ze-scan bese ebhala umbiko ngalokho akutholile. Kodwa-ke, esimweni esiphuthumayo, njengasesibhedlela noma egumbini lezimo eziphuthumayo, odokotela bangathola imiphumela ngesikhathi esingangehora.

Ngemva kokuba udokotela we-radiology kanye nodokotela wakho bebukeze imiphumela, bazokunikeza elinye i-aphoyintimenti noma bakushayele ucingo ukuze baxoxe ngemininingwane.

Ingabe i-CT scan iphephile?

Odokotela bathi ukuskena kwe-CT kuphephile kakhulu . Ukuskena kwe-CT kuphephile nasezinganeni ezincane. Uma kwenziwa ezinganeni, odokotela banciphisa umthamo ukuze banciphise inani lemisebe abachayeka kuyo.

Njenge-X-ray, ama-CT scan asebenzisa inani elincane lemisebe e-ionizing ukuthatha izithombe. Nazi ezinye zezingozi ezihlobene nale misebe:

• Ingozi yomdlavuza:Ukuhlolwa okusebenzisa imisebe, njenge-X-ray kanye ne-CT scans, kungandisa ingozi yokuba nomdlavuza ngenani elincane kakhulu. Kodwa umehluko mncane kakhulu kangangokuthi kunzima ukuwulinganisa ngokunembile.
• Ukusabela kokungezwani komzimba: Ngezinye izikhathi, ungaba nokusabela kokungezwani komzimba nezinto ezihlukile. Lokhu kungaba kuncane noma kungaba kubi kakhulu. Yingakho sibuza ukuthi ngabe uke waba nokusabela kokungezwani komzimba ngaphambili.

Uma unemibuzo noma ukukhathazeka mayelana nezingozi zempilo zokuhlolwa kwe-CT, khuluma nodokotela wakho ngakho ngokukhululekile. Bangakuchazela futhi bakusize wenze isinqumo esinolwazi.

Ngingakwazi yini ukwenza i-CT scan uma ngikhulelwe?

Uma ukhulelwe, noma ucabanga ukuthi ukhulelwe, kufanele nakanjani utshele udokotela wakho. Ukuskena kwe-CT kwe-pelvis yakho nesisu sakho kungaveza ingane yakho engakazalwa emisebeni ethile. Kodwa-ke, inani ngokuvamile aliphakeme ngokwanele ukulimaza ingane. Futhi, ukuskena kwe-CT kwezinye izingxenye zomzimba wakho (isb. ikhanda, isifuba) akubeki bungozi enganeni engakazalwa. Kodwa-ke, kungcono ukukhuluma nodokotela wakho ngalokhu bese uthola iseluleko.

Okokugcina, izinto ezimbalwa okufanele uzikhumbule (Umyalezo Wokuya Ekhaya)

Kuvamile ukuzizwa ukhathazekile kancane lapho udokotela wakho ekutshela ukuthi wenze i-CT scan (i-Computed Tomography). Kodwa khumbula, i-CT scan yile:

• Ukuhlolwa okungenabuhlungu.
• Ingozi iphansi kakhulu.
• Kuwusizo olukhulu kodokotela ekuxilongeni izimo eziningi ezahlukene zezokwelapha.

Ukuthola ukuxilongwa okunembile kuzosiza udokotela wakho ukuthi anqume ukwelashwa okungcono kakhulu kuwe. Ngakho-ke, ungesabi ukukhuluma nodokotela wakho nganoma yimiphi imibuzo noma ukukhathazeka ongase ube nakho. Futhi, buza ngezinye izivivinyo ezingaba khona. Khona-ke ungaba nokuqonda okucacile ngalokhu.
