Xa ugqirha ekuxelela ukuba wenze i-ultrasound scan, yinto eqhelekileyo kuthi ngoku. Kodwa ngamanye amaxesha xa esithi "Ndifuna ukwenza i-ultrasound scan ene-contrast," uyoyika kancinci kwaye ube nomdla, akunjalo? Yintoni "i-contrast"? Ngaba iya kubangela ingozi? Kutheni i-scan eqhelekileyo inganelanga? Namhlanje, siza kuthetha ngeempendulo zayo yonke le mibuzo engqondweni yakho ngendlela elula kakhulu kweli nqaku.
Ngamafutshane, yintoni iContrast-Enhanced Ultrasound (CEUS)?
Ukuze siqonde oku, masiqale sikhumbule ukuba yintoni i-ultrasound scan. I-ultrasound scan ibandakanya ukuthumela amaza esandi avakala kakhulu esingawavayo emzimbeni, aze amaza aphume kwizitho ezingaphakathi aze enze umfanekiso kwiscreen sekhompyutha.
I-Contrast-Enhanced Ultrasound (CEUS) yinguqulelo ephucuke kancinci yale nkqubo. Apha, ulwelo olukhethekileyo lufakwa emthanjeni wakho nge-cannula encinci (umgca we-IV). Oku sikubiza ngokuba yi-"contrast." Olu lwelo luqulethe izigidi zamaqamza omoya, amancinci kuneeseli zakho zegazi. Ezi zibizwa ngokuba yi-"microbubbles" ukuba zichanekile.
Njengoko la maqamza ehamba ngemithambo yegazi yakho ukuya kwizitho ezahlukeneyo zomzimba, xa amaza esandi avela kumatshini we-ultrasound ebetha la maqamza, ayangcangcazela kakhulu, ebuyisela amaza esandi ngamandla amakhulu. Ngenxa yoko, iindawo ezinalo mahluko zibonakala zikhanya ngakumbi nangakumbi kumfanekiso owubonayo kwiscreen sekhompyutha.
Ngamafutshane, olu mahluko lusebenza njengokukhanyisa 'ithotshi' encinci kwizitho zomzimba ezingaphakathi emzimbeni. Oku kuvumela ugqirha ukuba abone ukuhamba kwegazi ukuya kwizitho ngokucacileyo.
Yintoni eyona nto iphambili kuvavanyo lwe-CEUS?
Oogqirha basebenzisa olu vavanyo rhoqo ukuxilonga iimeko ezithile kwisibindi kunye nezintso, kodwa lukwasetyenziselwa ukuhlola amanye amalungu omzimba aliqela.
| Ilungu lokuhlola | Iimeko ezibonakalayo |
|---|---|
| Isibindi | Ukuchongwa kwezilonda ezinomhlaza nezingengomhlaza. |
| Izintso | Ukuchonga umhlaza wezintso, amaqhuqhuva, kunye nosulelo. |
| Ezinye izitho zomzimba | Ukujonga ukusebenza kunye nokuhanjiswa kwegazi kwamalungu afana nemithambo yegazi, intliziyo, inyongo, ipancreas, ipleyini, kunye nesinye. |
| Unyango lomhlaza | Ukubeka esweni indlela umhlaza osabela ngayo kunyango. |
Ziziphi iingenelo ze-CEUS kunezinye iintlobo ze-scan?
Ngamanye amaxesha oogqirha basebenzisa i-CEUS kunye okanye njengendlela eyahlukileyo yokuvavanya okufana ne-CT scans kunye ne-MRI scans kuba ineenzuzo ezininzi ezikhethekileyo.
- Ikhuselekile kwizintso: Umahluko osetyenziswa kwi-CT scan ngamanye amaxesha unokuba nefuthe kwizintso. Ke ngoko, i-CEUS lukhetho olukhuselekileyo kakhulu kumntu onesifo sezintso okanye onesifo se-CT contrast.
- Ingcono kubantwana abancinci: I-CT scan isebenzisa ii-X-ray. I-Ultrasound ayisebenzisi ii-X-ray. Ke ngoko, i-CEUS ikhuselekile kubantwana abancinci, ithintela ukuvezwa kwimitha engeyomfuneko.
Luhamba njani olu vavanyo? Uziva njani?
Le nkqubo ilula kakhulu. Yenzeka ngamacandelo amabini.
Inyathelo 1: Ukuskena rhoqo kwe-Ultrasound
Okokuqala, ingcali iza kusebenzisa ijeli ecacileyo eluswini lwakho ize ibeke isixhobo esiphathwayo esibizwa ngokuba yi-transducer phezu kwaso. Ngeli xesha, baza kufumana indawo echanekileyo yesitho esichaphazelekayo baze bathathe imifanekiso embalwa. Awuyi kuva ntlungu ngeli xesha, ngaphandle kokuba uzive urhawuzelelwa kancinci.
Inyathelo lesi-2: Ukuskena nge-ultrasound ngomahluko
Emva koko, ugqirha okanye umongikazi uza kufaka i-cannula encinci (IV) emthanjeni osengalweni okanye esandleni sakho aze afake ulwelo oluchaseneyo emzimbeni wakho. Usenokuziva urhawuzelelwa kancinci xa inaliti ifakwa kwaye isandla sakho sinokuziva sibanda njengoko ulwelo lungena.
Xa umahluko ungenile emzimbeni, ingcali iza kuphinda ihlole ize ithathe imifanekiso. Kulapho ke banokubona ngokucacileyo indlela igazi elihamba ngayo liye kwizitho zomzimba.
Musa ukukhathazeka! La maqamza omoya (`ii-microbubbles`) ngokwahlukileyo awahlali emzimbeni ixesha elide. Ayaqhuma emva kwexesha elithile, emva koko igesi engenabungozi iyanyibilika egazini ize iphume emzimbeni xa uphefumla.
Xa uvavanyo luphelile, ijeli iya kusulwa kwaye i-cannula engalweni yakho iya kususwa. Emva koko, ungagoduka ngaphandle kweengxaki.
Ndingazilungiselela njani ngaphambi kovavanyo?
Ngokwesiqhelo, oku akudingi kulungiselela okuninzi. Okufuneka ukwenze kukunxiba impahla ekhululekileyo nekhululekileyo. Nangona kunjalo, ngokuxhomekeke kwisitho esihlolwayo, ngamanye amaxesha unokufumana imiyalelo ekhethekileyo.
- Ukuzila ukutya: Ukuba luvavanyo lwesisu, uya kucetyiswa ukuba ungatyi okanye usele iiyure ezimbalwa ngaphambi kovavanyo.
- Isinyi esipheleleyo: Ukuba uvavanywa isinyi, ungacelwa ukuba usele amanzi uze kuvavanyo xa isinyi sakho sigcwele ngokupheleleyo.
Eyona nto ibalulekileyo kukulandela imiyalelo enikwe ngugqirha wakho okanye isibhedlele ngokuchanekileyo.
Ngaba kukho naziphi na iingozi okanye iziphumo ebezingalindelekanga koku?
Okokuqala, iteknoloji ye-ultrasound yindlela ekhuselekileyo kakhulu engenazo iziphumo ebezingalindelekanga eziyingozi.
Nangona kunjalo, abanye abantu banokufumana iziphumo ebezingalindelekanga ezivela kwi-contrast fluid. Nangona kunjalo, oku kunqabile kakhulu . Ezi ziphumo bezingalindelekanga zihlala zincinci. Makhe sibone ukuba ziyintoni na.
| Inqanaba lesiphumo esingesihle | Iimpawu ezinokwenzeka |
|---|---|
| Iziphumo ebezingalindelekanga ezincinci (idla ngokuziphilisa) | Intloko ebuhlungu, isicaphucaphu, ukurhawuzelelwa okanye ukurhawuzelelwa eluswini, intlungu okanye ubushushu kwindawo efakwe kuyo inaliti, ukuziva ubushushu emzimbeni, ukungakhululeki esifubeni, isiyezi, incasa engaqhelekanga emlonyeni. |
| Iziphumo ebezingalindelekanga eziphakathi (Unyango lwezonyango lunokufuneka) | Ukucaphuka okanye ukuhlanza okukhulu, ukucutheka kweendlela zomoya (i-bronchospasm), ukudumba kobuso, ukuquleka, uxinzelelo lwegazi oluphantsi. |
| Iziphumo ebezingalindelekanga eziqatha (Ayiqhelekanga kakhulu) | I-Anaphylaxis - Le yimpendulo enzima kakhulu ye-allergy enokuba yingozi kubomi. Nangona kunjalo, oku kunqabile kakhulu. Abasebenzi bezonyango bahlala bekulungele ukujongana neengxamiseko ezinjalo. |
Ngokwezibalo, iziphumo ebezingalindelekanga ezincinci zenzeka kubantu aba-5 kwabayi-100 (5%). Iimpendulo eziqatha zenzeka kubantu abangaphantsi komnye kwabayi-10,000 (ngaphantsi kwe-0.01%). Ngoko ke musa ukoyika kakhulu oku.
Ndiza kuyifumana nini ingxelo?
Imifanekiso efunyenwe kuvavanyo ifundwa ngononophelo yingcali ye-radiology kwaye kulungiswa ingxelo. Emva koko, loo ngxelo inikwa ugqirha wakho onyangayo. Ekugqibeleni, ugqirha wakho uya kukuchazela iziphumo zaloo ngxelo.
Umyalezo Wokuya Ekhaya
- I-Contrast-Enhanced Ultrasound (CEUS) yi-ultrasound scan ephucukileyo esebenzisa ulwelo olukhethekileyo oluneziqamza zomoya ezincinci ukuze kubonakale ngokucacileyo indlela igazi elihamba ngayo kwizitho zomzimba.
- Oku kuluncedo kakhulu ekuxilongeni izifo zesibindi nezintso. Lukhetho olukhuselekileyo kune-CT scan kwizigulana zezintso kunye nabantwana abancinci.
- Olu vavanyo lulula kakhulu. Akukho ntlungu ngaphandle kokufakwa kwe-cannula encinci engalweni kunye nokufakwa kolwelo oluchaseneyo.
- Iziphumo ebezingalindelekanga ezivela kwi-contrast fluid azifumaneki rhoqo. Musa ukoyika. Ukuba une-allergies, yazisa ugqirha wakho ngaphambi kovavanyo.
- Kubaluleke kakhulu ukulandela imiyalelo enikwe sisibhedlele okanye ngugqirha wakho (umz. ukuzila ukutya) ngokuchanekileyo ukuze ufumane iziphumo ezichanekileyo.
