Uma udokotela ekutshela ukuthi wenze i-ultrasound scan, kuyinto esijwayele kakhulu manje. Kodwa ngezinye izikhathi uma ethi "Ngidinga ukwenza i-ultrasound scan ene-contrast," uyasaba kancane futhi ube nelukuluku, akunjalo? Kuyini "i-contrast"? Ingabe izodala umonakalo? Kungani i-ultrasound scan evamile inganele? Namuhla, sizoxoxa ngezimpendulo zayo yonke le mibuzo engqondweni yakho ngendlela elula kakhulu kulesi sihloko.
Kalula nje, iyini i-Contrast-Enhanced Ultrasound (CEUS)?
Ukuze siqonde lokhu, ake siqale sikhumbule ukuthi kuyini ukuskena kwe-ultrasound. Ukuskena kwe-ultrasound kuhilela ukuthumela amaza omsindo avame kakhulu esingakwazi ukuwazwa emzimbeni, bese amaza egxuma ezithweni ezingaphakathi bese edala isithombe esikrinini sekhompyutha.
I-Contrast-Enhanced Ultrasound (CEUS) inguqulo ethuthuke kancane yale nqubo. Lapha, uketshezi olukhethekile lufakwa emthanjeni wakho nge-cannula encane (umugqa we-IV). Yilokhu esikubiza ngokuthi "umehluko." Lolu ketshezi luqukethe izigidi zamabhamuza omoya, amancane kunamaseli akho egazi. Lawa abizwa ngokuthi "amabhamuza amancane" uma kukhulunywa ngawo.
Njengoba la mabhamuza edlula emithanjeni yakho yegazi eya ezithweni ezahlukahlukene, lapho amaza omsindo avela emshinini we-ultrasound eshaya la mabhamuza, ayavevezela kakhulu, ebuyisela amaza omsindo emuva ngamandla amakhulu. Ngenxa yalokho, izindawo ezinalokhu kuhluka zibonakala zikhanya kakhulu futhi zicacile esithombeni osibona esikrinini sekhompyutha.
Kalula nje, lokhu kungafani kusebenza njengokukhanyisa 'ithoshi' elincane ezithweni zomzimba. Lokhu kuvumela udokotela ukubona ukugeleza kwegazi ezithweni zomzimba ngokucacile.
Iyini inhloso eyinhloko yokuhlolwa kwe-CEUS?
Odokotela basebenzisa lolu vivinyo kaningi ukuthola izimo ezithile esibindini nasezinso, kodwa futhi lusetshenziselwa ukuhlola ezinye izitho eziningana.
| Isitho esihlolayo | Izimo ezibonakalayo |
|---|---|
| Isibindi | Ukuhlonza izilonda ezinomdlavuza kanye nezingezona umdlavuza. |
| Izinso | Ukuhlola umdlavuza wezinso, ama-cyst, kanye nezifo. |
| Ezinye izitho zomzimba | Ukuhlola ukusebenza kanye nokutholakala kwegazi kwezitho ezifana nemithambo yegazi, inhliziyo, inyongo, i-pancreas, i-spleen, kanye nesinye. |
| Ukwelashwa komdlavuza | Ukuqapha indlela isimila somdlavuza esisabela ngayo ekwelashweni. |
Yiziphi izinzuzo ze-CEUS kunezinye izinhlobo zokuskena?
Ngezinye izikhathi odokotela basebenzisa i-CEUS kanye noma njengenye indlela yokuhlolwa okufana nokuskena kwe-CT kanye nokuskena kwe-MRI ngoba kunezinzuzo eziningana ezihlukile.
- Kuphephile ezinso: Umehluko osetshenziswa ku-CT scan ngezinye izikhathi ungaba nomthelela ezinso. Ngakho-ke, i-CEUS iyindlela ephephile kakhulu kumuntu onesifo sezinso noma onesifo sokungezwani komzimba ne-CT contrast.
- Kungcono ezinganeni ezincane: I-CT scan isebenzisa i-X-ray. I-Ultrasound ayisebenzisi i-X-ray. Ngakho-ke, i-CEUS iphephile ezinganeni ezincane, igwema ukuchayeka emisebeni engadingekile.
Kuhamba kanjani lokhu kuhlolwa? Uzizwa kanjani?
Lonke lolu hlelo lulula kakhulu. Lwenzeka ngezigaba ezimbili.
Isinyathelo 1: Ukuskena Okuvamile Kwe-Ultrasound
Okokuqala, uchwepheshe uzofaka ijeli ecacile esikhumbeni sakho bese ebeka idivayisi ephathwayo ebizwa ngokuthi i-transducer phezu kwayo. Phakathi nalesi sikhathi, bazobona indawo eqondile yesitho okukhulunywa ngaso bese bethatha izithombe eziyisisekelo. Ngeke uzwe ubuhlungu phakathi nalesi sikhathi, ngaphandle komuzwa omncane wokucasuka.
Isinyathelo 2: Ukuskena kwe-Ultrasound ngokuqhathanisa
Ngemuva kwalokho, udokotela noma umhlengikazi uzofaka i-cannula encane (IV) emthanjeni ongalweni noma esandleni sakho bese efaka uketshezi oluhlukile emzimbeni wakho. Ungase uzizwe umuzwa omncane wokuhlaba lapho inaliti ifakwa futhi isandla sakho singase sizizwe sibanda njengoba uketshezi lungena.
Uma umehluko usungene emzimbeni, uchwepheshe uzophinde askene futhi athathe izithombe. Yilapho bebona khona ngokucacile ukuthi igazi ligeleza kanjani liye ezithweni zomzimba.
Ungakhathazeki! Lawa ma-bubble omoya (`ama-microbubble`) ngokuphambene awahlali isikhathi eside emzimbeni. Ayaqhuma ngemva kwesikhashana, bese igesi engenangozi incibilika egazini bese iphuma emzimbeni uma uphefumula.
Uma ukuhlolwa sekuphelile, ijeli izosulwa bese kususwa i-cannula engalweni yakho. Ngemva kwalokho, ungaya ekhaya ngaphandle kwezinkinga.
Kufanele ngilungiselele kanjani ngaphambi kokuhlolwa?
Ngokuvamile, lokhu akudingi ukulungiselela okuningi. Okudingeka ukwenze nje ukugqoka izingubo ezikhululekile nezikhululekile. Kodwa-ke, kuye ngokuthi isitho sihlolwa kanjani, ngezinye izikhathi ungathola imiyalelo ekhethekile.
- Ukuzila Ukudla: Uma kuwukuhlolwa kwesisu, uzokwaziswa ukuthi ugweme ukudla noma ukuphuza amahora ambalwa ngaphambi kokuhlolwa.
- Isinyi esiphelele: Uma uhlolwa isinyi, ungase ucelwe ukuthi uphuze amanzi bese uza kohlolwa uma isinyi sakho sesigcwele ngokuphelele.
Into ebaluleke kakhulu ukulandela imiyalelo enikezwe udokotela wakho noma isibhedlela ngqo.
Ingabe kukhona izingozi noma imiphumela emibi kulokhu?
Okokuqala, ubuchwepheshe be-ultrasound buyindlela ephephile kakhulu engenazo imiphumela emibi eyingozi.
Kodwa-ke, abanye abantu bangase babe nemiphumela emibi evela ku-contrast fluid. Kodwa-ke, lokhu akuvamile kakhulu . Le miphumela emibi ivame ukuba mincane. Ake sibone ukuthi iyini.
| Izinga lomphumela ongemuhle | Izimpawu ezingaba khona |
|---|---|
| Imiphumela emibi emincane (ngokuvamile ukuzelapha) | Ikhanda elibuhlungu, isicanucanu, ukulunywa noma ukuqubuka esikhumbeni, ubuhlungu noma ukufudumala endaweni yomjovo, umuzwa wokushisa emzimbeni, ukungakhululeki esifubeni, isiyezi, ukunambitheka okungajwayelekile emlonyeni. |
| Imiphumela emibi emaphakathi (Kungadingeka ukwelashwa kwezokwelapha) | Ukucanuzela noma ukuhlanza okukhulu, ukuncipha kwemigudu yomoya (i-bronchospasm), ukuvuvukala kobuso, ukuquleka, umfutho wegazi ophansi. |
| Imiphumela emibi kakhulu (Akuvamile kakhulu) | I-Anaphylaxis - Lokhu kuyisimo esibi kakhulu sokungezwani komzimba esingasongela impilo. Kodwa-ke, lokhu akuvamile kakhulu. Abasebenzi bezokwelapha bahlala bekulungele ukubhekana nezimo eziphuthumayo ezinjalo. |
Ngokwezibalo, imiphumela emibi emincane ivela kubantu abambalwa abangafika kwabayi-5 kwabayi-100 (5%). Ukusabela okukhulu kwenzeka kubantu abangaphansi koyedwa kwabayi-10,000 (ngaphansi kuka-0.01%). Ngakho-ke ungakhathazeki kakhulu ngalokhu.
Ngizowuthola nini umbiko?
Izithombe ezitholwe ekuhlolweni zifundwa ngokucophelela ngudokotela we-radiologist bese kulungiswa umbiko. Ngemuva kwalokho, lowo mbiko unikezwa udokotela wakho okwelaphayo. Ekugcineni, udokotela wakho uzokuchazela imiphumela yalowo mbiko.
Umlayezo Wokuya Nawe Ekhaya
- I-Contrast-Enhanced Ultrasound (CEUS) iyi-ultrasound scan ethuthukisiwe esebenzisa uketshezi olukhethekile oluqukethe amabhamuza amancane omoya ukuze kubonakale ngokucacile ukuthi igazi ligeleza kanjani ezithweni zomzimba.
- Lokhu kuwusizo kakhulu ekuxilongeni izifo zesibindi nezinso. Kuyindlela ephephile yokwelapha iziguli zezinso nezingane ezincane esikhundleni se-CT scan.
- Lolu vivinyo lulula kakhulu. Akukho ukungakhululeki ngaphandle kokufakwa kwe-cannula encane engalweni bese kunikezwa uketshezi lokuhlukanisa.
- Imiphumela emibi evela ku-contrast fluid ayivamile kakhulu. Ungakhathazeki. Uma une-allergies, yazisa udokotela wakho ngaphambi kokuhlolwa.
- Kubaluleke kakhulu ukulandela imiyalelo enikezwe yisibhedlela noma udokotela wakho (isib. ukuzila ukudla) ngqo ukuze uthole imiphumela enembile.
