Ukuskena kwe-MRI emadolweni

Ukuskena kwe-MRI MRI (i-magnetic resonance imaging) isebenzisa amandla avela kumazibuthe aqinile ukudala izithombe zokuhlangana kwamadolo nezicubu nezicubu.

I-MRI ayisebenzisi imisebe (x-ray). Izithombe ezi-Single ze-MRI zibizwa ngokuthi izingcezu. Izithombe zingagcinwa kukhompyutha noma ziphrintwe kwifilimu. Isivivinyo esisodwa sikhiqiza izithombe eziningi.

Uzogqoka ingubo yasesibhedlela noma izingubo ezingenaziphu zensimbi noma izifinyezo (ezinjengezithukuthuku nesikibha). Sicela ususe amawashi akho, izingilazi, ubucwebe, nesikhwama semali. Izinhlobo ezithile zensimbi zingadala izithombe ezifiphele.

Uzolala etafuleni elincane elingena kuskena esikhulu esifana nomhubhe.

Ezinye izivivinyo zisebenzisa udayi okhethekile (umehluko). Isikhathi esiningi, uzoluthola udayi ngomthambo (IV) engalweni noma esandleni sakho ngaphambi kokuhlolwa. Kwesinye isikhathi, udayi ujojelwa emalungeni. Idayi isiza udokotela we-radiologist ukuthi abone izindawo ezithile ngokucace kakhudlwana.

Ngesikhathi seMRI, umuntu osebenzisa umshini uzokubuka ukwelinye igumbi. Ukuhlolwa kuvame ukuthatha imizuzu engama-30 kuye kwangama-60, kepha kungathatha isikhathi eside. Kungaba phezulu. Uchwepheshe angakunika ama-plugs endlebe uma kudingeka.

Ungacelwa ukuthi ungadli noma uphuze noma yini amahora amane kuya kwayisithupha ngaphambi kokuskena.

Tshela umhlinzeki wakho wezokunakekelwa kwezempilo uma wesaba izindawo ezivaliwe (une-claustrophobia). Unganikezwa umuthi ozokusiza uzizwe ulele futhi ungakhathazeki kangako. Umhlinzeki wakho angaphakamisa i-MRI "evulekile", lapho umshini ungasondelene kakhulu nomzimba.

Ngaphambi kokuhlolwa, tshela umhlinzeki wakho uma ngabe:

• Iziqeshana ze-aneurysm zobuchopho
• Izinhlobo ezithile zamavalvu enhliziyo yokufakelwa
• Inhliziyo defibrillator noma i-pacemaker
• Ukufakwa kwendlebe kwangaphakathi (cochlear)
• Isifo sezinso noma i-dialysis (ungahle ungakwazi ukuthola umehluko)
• Amalunga wokufakelwa asanda kufakwa
• Izinhlobo ezithile ze-vascular stents
• Kusetshenziswe ngensimbi yensimbi esikhathini esedlule (ungadinga ukuhlolwa ukuhlola izingcezu zensimbi emehlweni akho)

Ngoba i-MRI iqukethe odonsa abanamandla, izinto zensimbi azivunyelwe ukungena egumbini elinesithwebuli se-MRI:

• Amapeni, okhiye bokuphaka, nezibuko zamehlo zingandiza zinqamule igumbi.
• Izinto ezinjengobucwebe, amawashi, amakhadi esikweletu nezinsiza-kuzwa zingalimala.
• Izikhonkwane, okokufaka izinwele, uziphu wensimbi, nezinto ezifanayo zensimbi kungasonta izithombe.
• Umsebenzi wamazinyo osusekayo kufanele ukhishwe ngaphambi nje kokuskena.

Ukuhlolwa kwe-MRI akubangeli buhlungu. Uzodinga ukuqamba amanga unganyakazi. Ukunyakaza okuningi kungafiphaza izithombe ze-MRI futhi kudale amaphutha.

Itafula lingaba nzima noma libande, kepha ungacela ingubo noma umcamelo. Umshini wenza umsindo omkhulu wokuduma nokuhayiza lapho uvuliwe. Ungafaka ama-plugs endlebe ukusiza ukuvimba umsindo.

I-intercom egumbini ikuvumela ukuba ukhulume nomuntu nganoma yisiphi isikhathi. Amanye ama-MRIs anamathelevishini namahedfoni akhethekile okusiza ukuhamba kwesikhathi.

Asikho isikhathi sokululama, ngaphandle kokuthi unikwe umuthi wokuphumula. Ngemuva kokuskena kwe-MRI, ungabuyela ekudleni kwakho okujwayelekile, emsebenzini, nasemithini.

Umhlinzeki wakho anga-oda lokhu kuhlolwa uma une:

• Umphumela ongajwayelekile ku-x-ray yedolo noma ukuskena kwethambo
• Umuzwa wokuthi idolo lakho linikela ngokuhlanganyela kwamadolo
• Ukwakhiwa koketshezi oluhlangene ngemuva kwedolo (i-Baker cyst)
• Ukuqoqa oketshezi emadolweni
• Ukutheleleka kwamadolo
• Ukulimala kwekepisi
• Ubuhlungu emadolweni ngomkhuhlane
• Ukukhiya amadolo lapho uhamba noma unyakaza
• Izimpawu zokulimala kwemisipha yamadolo, uqwanga, noma imisipha
• Ubuhlungu bamadolo obungeke bube ngcono ngokwelashwa
• Ukuntengantenga kwamadolo

Ungase futhi ube nalolu vivinyo ukuhlola intuthuko yakho ngemuva kokuhlinzwa kwedolo.

Umphumela ojwayelekile usho ukuthi idolo lakho libukeka LILUNGILE.

Imiphumela engajwayelekile kungenzeka ukuthi ibangelwa ukuqhuma noma ukudabuka kwemisipha endaweni yedolo.

Imiphumela engajwayelekile futhi ingabangelwa:

• Ukwehla noma izinguquko ezenzeka ngobudala
• Ukulimala kweMeniscus noma uqwanga
• I-arthritis yamadolo
• I-Avascular necrosis (ebizwa nangokuthi i-osteonecrosis)
• Isimila samathambo noma umdlavuza
• Ithambo eliphukile
• Ukwakhiwa koketshezi oluhlangene ngemuva kwedolo (i-Baker cyst)
• Ukutheleleka ethanjeni (i-osteomyelitis)
• Ukuvuvukala
• Ukulimala kwengubo yamadolo

Khuluma nomhlinzeki wakho uma unemibuzo noma ukukhathazeka.

I-MRI ayiqukethe imisebe. Akubanga khona miphumela emibi ebikiwe evela kumandla kazibuthe namagagasi omsakazo.

Uhlobo oluvame kakhulu lokuqhathanisa (udayi) olusetshenzisiwe yi-gadolinium. Kuphephe kakhulu. Ukungezwani komzimba nezinto ezithile akuvamile. Kodwa-ke, i-gadolinium ingaba yingozi kubantu abanezinkinga zezinso ezidinga i-dialysis. Uma unezinkinga zezinso, sicela utshele umhlinzeki wakho ngaphambi kokuhlolwa.

Amandla kazibuthe aqinile adalwe ngesikhathi seMRI angadala ukuthi izinhliziyo zisebenze futhi nezinye izinto zokufakelwa zingasebenzi. Kungadala izingcezu ezincane zensimbi emzimbeni wakho ukuthi zihambe noma zigudluke. Ngezizathu zokuphepha, ngicela ungalethi noma yini equkethe insimbi egumbini lesithwebuli.

Ukuhlolwa okungenziwa esikhundleni se-MRI yamadolo kufaka:

• Ukuhlolwa kwe-CT kwedolo
• X-ray emadolweni

I-MRI - idolo; Imagnetic resonance imaging - idolo

• Ukwakhiwa kabusha kwe-ACL - ukukhishwa
