Uma udokotela wakho ekutshela ukuthi wenze i-MRA scan, ungase uzizwe wesaba kancane. Kuvamile ukuba nemibuzo eminingi efana nokuthi, "Luhlobo luni lokuhlolwa lolu? Ingabe bazofaka umshini omkhulu? Ingabe kuzobuhlungu?" Kodwa ungakhathazeki, i-MRA empeleni iyindlela yokuhlola ephephile kakhulu futhi engenabuhlungu. Namuhla, sizoxoxa ngayo ngendlela elula ongayiqonda.
Iyini i-MRA?
Kalula nje, i-MRA isifinyezo se -Magnetic Resonance Angiography . Lolu futhi uhlobo lwe-MRI scan, kodwa lolu lugxile ngqo emithanjeni yegazi emzimbeni wakho. Okusho ukuthi, luhlola isimo semithambo yegazi nemithambo yegazi, imithambo yegazi ethwala igazi emzimbeni wakho wonke.
Enye yezinzuzo ezinkulu zalokhu ukuthi ukuhlolwa okungangenisi ukutheleleka okungenziwa ngaphandle komzimba. Kungenzeka ukuthi uke wezwa ngokuhlolwa okuvamile kwe-angiography, lapho kufakwa khona ithubhu elincane (i-catheter) emthanjeni wegazi ukuze lihlolwe. Kodwa nge-MRA, akukho lutho olufana nalolo olwenziwayo. Ngakho-ke kulula kakhulu.
Udokotela usebenzisa i-MRA ukuthola ukuthi ngabe kukhona yini inkinga ngemithambo yegazi yakho, njengomthambo ovalekile. Ulwazi oluvela kulolu vivinyo lubaluleke kakhulu ekuqapheni izinguquko emithanjeni yegazi yakho ngemva kokwelashwa nokuhlela ukuhlinzwa.
Yini engabonakala nge-MRA scan?
Lokhu kuhlolwa kungahlola imithambo yegazi ezingxenyeni ezahlukene zomzimba.
| Ingxenye yomzimba | Incazelo elula |
|---|---|
| I-Aorta | Umthambo omkhulu, omkhulu kunayo yonke othwala igazi lisuka enhliziyweni liye emzimbeni. |
| Imithambo yegazi yobuchopho | Inethiwekhi ethambile yemithambo yegazi enikeza igazi ebuchosheni bakho. |
| Imithambo ye-carotid | Imithambo emibili eyinhloko ethwala igazi liye ebuchosheni isuka ezinhlangothini zombili zentamo. |
| Imithambo yenhliziyo | Umthambo wegazi obaluleke kakhulu ohlinzeka ngegazi emisipheni yenhliziyo. |
| Imithambo yegazi engaphandle kwezingalo nemilenze | Imithambo yegazi ethwala igazi iye ezingalweni, emilenzeni, kanye naseminweni. |
| Imithambo yephaphu | Imithambo yegazi ethwala igazi lisuka enhliziyweni liye emaphashini. |
| Imithambo yezinso | Imithambo yegazi ehambisa igazi ezinso. |
Yiziphi izifo ezingatholakala nge-MRA?
Lokhu kuhlolwa kungathola izifo ezahlukahlukene ezihlobene nemithambo yegazi.
| Isimo sezokwelapha | Igama lesayensi yezokwelapha (Igama lesiNgisi) |
|---|---|
| Umthambo wegazi uyaqhuma noma udabuke odongeni lwawo | Ukuvuvukala kwemithambo yegazi / ukuqhekeka kwe-aorta |
| Ukuvaleka komthambo wegazi | I-stenosis yemithambo yegazi |
| Ukuvaleka okungavamile kwemithambo yegazi nemithambo yegazi | Ukukhubazeka kwemithambo yegazi |
| Ukuqongelela kwamafutha emithanjeni | I-atherosclerosis |
| Amahlule egazi emithanjeni yemilenze | I-Deep Vein Thrombosis (DVT) |
| Ihlule legazi eliya emaphashini | I-Pulmonary embolism (PE) |
| Isifo senhliziyo esizalwa naso | Isifo senhliziyo esizalwa naso |
| Yini ebonakala ngokukhethekile nge-MRA yobuchopho? | |
| Ingozi yokuqhuma kwe-aneurysm yobuchopho | Ama-aneurysms obuchopho |
| Izimpawu zesifo sohlangothi | Ubufakazi bokushaywa yisifo sohlangothi |
| Ukungahambi kahle emithanjeni yegazi | Ukukhubazeka kwemithambo yegazi |
Ngezinye izikhathi, odokotela batusa ukuhlolwa kobuchopho kwe-MRA ukuze kutholakale imbangela yekhanda elibuhlungu eliqhubekayo.
Lo mshini we-MRA usebenza kanjani?
Lena inqubo ethakazelisayo kakhulu. I-MRA scan isebenzisa insimu enamandla yamagnetic kanye namagagasi omsakazo . Lokhu kusetshenziselwa ukudala izithombe ezinemininingwane zemithambo yegazi emzimbeni wakho. Udokotela angabuka lezi zithombe esikrinini sekhompyutha.
Into ebaluleke kakhulu lapha ukuthi i-MRA ayisebenzisi noma yimiphi imisebe efana ne-X-ray , ngakho-ke iphephile kakhulu kune-X-ray noma i-CT scan.
Ingabe zikhona izinhlobo zokuhlolwa kwe-MRA?
Yebo, kunezinhlobo eziningana zama-MRA kuye ngezidingo zakho.
- I-MRA ethuthukisiwe: Kulokhu, inani elincane lomuthi (idayi yokungafani) lifakwa emthanjeni wakho. Lo muthi wenza imithambo yegazi ibonakale ngokucacile, okwenza kube lula ukuthola isifo.
- I-MRA Engathuthukisiwe: Lolu hlobo alusebenzisi idayi yokuhlukanisa. Uma unesifo sezinso, le dayi ingaba yingozi emzimbeni wakho. Lolu hlobo lusetshenziswa ezimweni ezinjalo.
- I-MRA ye-2D neye-3D: Ngezinye izikhathi izithombe ezinezinhlangothi ezimbili (2D) zithathwa ukuze kubonwe ingxenye ende yomthambo wegazi. Izithombe ezinezinhlangothi ezintathu (3D) zithathwa ukuze kubonwe inethiwekhi encane neyinkimbinkimbi yemithambo ezindaweni ezifana nobuchopho.
Kufanele uzilungiselele kanjani ukuskena kwe-MRA?
Ngaphambi kokuskena, udokotela noma abasebenzi basesibhedlela bazokubuza imibuzo embalwa. Kubalulekile ukuze uphephe ukuphendula le mibuzo ngokwethembeka .
- Ingabe unezingxenye zensimbi emzimbeni wakho? Lona umbuzo obaluleke kakhulu. Ngenxa yokuthi umshini we-MRA unemagnethi enamandla kakhulu, kungaba yingozi uma unezingxenye zensimbi emzimbeni wakho. Isibonelo: ama-pacemaker, ama-clip athile ngemva kokuhlinzwa, izinduku zensimbi, amalunga okwenziwa, noma izingcezu zensimbi ezingene emzimbeni ngengozi ethile.
- Uyasaba yini ukuba sezindaweni ezivalekile? Abanye abantu bazizwa besaba kancane futhi bengakhululekile uma bengena ngaphakathi kulo mshini. Lokhu kubizwa ngokuthi "i-claustrophobia." Uma unenkinga enjalo, sitshele kusenesikhathi. Khona-ke udokotela angakunika umuthi omncane wokukuphumuza. Ezinye izibhedlela nazo zinemishini ye-MRI "evulekile".
- Ingabe ukhulelwe noma uyancelisa? Kufanele futhi wazise udokotela wakho ngalokhu.
- Ezinye izifo, ukungezwani komzimba, noma ukuhlinzwa oke wakwenza , ikakhulukazi uma unesifo sezinso noma sesibindi, kungakuvimbela ekutholeni idayi yokuhlukanisa okukhulunywe ngayo ekuqaleni.
Udokotela wakho uzokunikeza imiyalelo yokuthi ungadla kanjani, uphuze kanjani, futhi uthathe imithi yakho ngaphambi kokuskena. Landela leyo miyalelo ngqo. Uma unikezwa umuthi wokudambisa, ungakhohlwa ukuletha othile ozokuthatha akuyise ekhaya ngemva kokuskena .
Kwenzekani ngesikhathi sokuskena?
Kulungile, manje ake sibone ukuthi kwenzekani ngesikhathi sokuskena. Uma usukwazi lokhu isinyathelo ngesinyathelo, ukwesaba kwakho kuzophela.
1. Okokuqala, uzolaliswa embhedeni oxhunywe kuskena.
2. Umshini unomsindo omncane, ngakho uzonikezwa ama-headphone noma ama-earplug ukuze unciphise umsindo.
3. Uzoyalwa ukuba uhlale uthule ngangokunokwenzeka ngesikhathi sokuskena, njengoba ukunyakaza kungathinta ukucaca kwezithombe. Ngezinye izikhathi ungase ucelwe ukubamba umoya wakho isikhashana.
4. Uzonikezwa into encane efana nebhola esandleni sakho. Uma uzizwa ungakhululekile, ungayicindezela bese utshela abasebenzi. Bazobe bekubuka besegumbini eliseduze futhi bangakhuluma nawe.
5. Bese umbhede okuwo ungena emshinini. Lona umshini oyindilinga onembobo enkulu phakathi.
6. Ukuskena kuzoqala manje. Uma udinga ukunikezwa idayi yokuhlukanisa, izofakwa nge-cannula engalweni yakho ngaleso sikhathi. Ungase uzizwe ukunambitheka okuncane kwensimbi emlonyeni wakho, okuzophela ngemva kwesikhashana.
7. Ngemva kokunikezwa umuthi, ngizothatha ezinye izithombe.
8. Uma ukuhlolwa sekuqediwe, umbhede uzophuma futhi. Ngemuva kwalokho i-cannula engalweni yakho izosuswa.
Ukuskena kwe-MRA kuvame ukuthatha imizuzu ephakathi kuka-20 no-60 ukuqeda.
Ingabe kukhona ingozi kulokhu?
Sekukonke, i-MRA iyisivivinyo esiphephile kakhulu .
- Lokhu akusebenzisi imisebe.
- Akukho okufakwa emzimbeni (ngaphandle kodayi wokungafani).
- Uma unenkinga yezinso futhi usengozini yokuthola umbala ohlukile, ukuskena kungenziwa ngaphandle kwayo.
Akuvamile kakhulu, abanye abantu bangase babe nekhanda elibuhlungu, isisu esibuhlungu, noma ukusabela kokungezwani komzimba nodayi wokungafani. Kodwa lokhu akuvamile kakhulu.
Ngemva kokuskena kanye nombiko
Ngaphandle kokuthi unikezwe umuthi wokudambisa, ungazishayela imoto bese wenza imisebenzi yakho evamile ngemva kokuskena. Uma unikezwe umuthi, kuzodingeka nakanjani uphelezelwe ngomunye umuntu ukuya ekhaya.
Kungathatha izinsuku ezimbalwa ukuthi izithombe zakho ze-MRA scan zibuyekezwe ngudokotela we-radiologist, kulungiswe umbiko, bese uthunyelwa kudokotela wakho. Uma ungaphenduli ngemva kwesonto noma ngaphezulu, buza udokotela wakho ngakho.
Ngokusekelwe emiphumeleni yombiko wakho, udokotela wakho uzokuchazela ukuthi ngabe kukhona yini izinkinga ngemithambo yegazi yakho. Ungase ubone igama elithi "okungaphawuleki" embikweni wakho. Ungakhathazeki ngalokho. Ngokwezokwelapha, lisho ukuthi "akukho nkinga, konke kujwayelekile."
Yebo, umshini we-MRA ungethusa kancane ukuwubona. Kodwa ungagqoka ama-headphone ukuze uvale umsindo, futhi ungaphuza imithi uma ungakhululekile ukuba sendawo evalekile. Lokhu kuhlolwa kunikeza udokotela wakho ulwazi oluningi olubalulekile ngomzimba wakho. Lolo lwazi yilona oluzomsiza ukuthi anqume ukuthi yikuphi ukwelashwa okudingayo.
Umlayezo Wokuya Nawe Ekhaya
- I-MRA uhlobo olukhethekile lwe-MRI scan olubheka kakhulu imithambo yegazi (izinzwa) emzimbeni wakho.
- Lokhu kuphephile kakhulu . Akusebenzisi imisebe eyingozi njenge-X-ray noma i-CT scans.
- Ngaphambi kokuskena, qiniseka ukuthi utshela udokotela nganoma yiziphi izingxenye zensimbi emzimbeni wakho (ama-pacemaker, ama-clip), ukungezwani komzimba, ukukhulelwa, nezinye izifo.
- Akukho buhlungu ngesikhathi sokuhlolwa. Okuwukuphela kokungakhululeki umsindo womshini kanye nokuphoqeleka ukuthi uhlale unganyakazi.
- Ulwazi olutholakale kulolu vivinyo lusiza odokotela ukuthi bahlole ngokunembile isimo sakho futhi banikeze ukwelashwa okungcono kakhulu.
