Ukuskena kwe-MRI yomlomo wesibeletho

Iskena se-MRI yomlomo wesibeletho (i-magnetic resonance imaging) sisebenzisa amandla avela kumazibuthe aqinile ukwakha izithombe zengxenye yomgogodla egijima endaweni yentamo (umgogodla womlomo wesibeletho).

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). Qiniseka ukuthi ukhumula iwashi lakho, ubucwebe nesikhwama semali. Ezinye izinhlobo zensimbi zingadala ukufiphala kwezithombe.

Uzolala etafuleni elincane elingena kuskena esimise okomhubhe.

Ezinye izivivinyo zisebenzisa udayi okhethekile (umehluko). Isikhathi esiningi, uzothola udayi ngomthambo engalweni noma esandleni sakho ngaphambi kokuhlolwa. Idayi nayo inganikezwa ngomjovo. 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.

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.

Izizathu ezivame kakhulu zalesi sivivinyo yilezi:

• Ubuhlungu obukhulu bentamo, ihlombe, noma ingalo obungabi ngcono emva kokwelashwa
• Ubuhlungu bezintambo kanye nobuthakathaka bomlenze, ukuba ndikindiki, noma ezinye izimpawu

Ukuskena kwe-MRI yomlomo wesibeletho kungenziwa futhi:

• Ukukhubazeka kokuzalwa komgogodla
• Ukutheleleka okubandakanya umgogodla wakho
• Ukulimala noma ukuhlukumezeka umgogodla
• I-Multiple sclerosis
• I-scoliosis enamandla
• Isimila noma umdlavuza emgogodleni
• I-arthritis emgogodleni

I-MRI isebenza kangcono kune-CT scan ekuhloleni lezi zinkinga isikhathi esiningi.

I-MRI yomlomo wesibeletho nayo ingenziwa ngaphambi kokuhlinzwa komgogodla.

Umphumela ojwayelekile usho ukuthi ingxenye yomgogodla ewela entanyeni yakho nezinzwa eziseduze zibonakala zijwayelekile.

Izizathu ezivame kakhulu zomphumela ongajwayelekile yilezi:

• I-disk ye-Herniated noma "eshibhile" (i-radiculopathy yomlomo wesibeletho)
• Ukuncipha komgogodla wesibeletho (i-spinal stenosis)
• Ukugqoka okungavamile kwamathambo kanye noqwanga entanyeni (i-cervical spondylosis)

Imiphumela engajwayelekile futhi ingabangelwa:

• Izinguquko ezizenzakalelayo ngenxa yeminyaka
• Ukutheleleka kwamathambo (i-osteomyelitis)
• Ukuvuvukala kwediski (i-diskitis)
• Ukutheleleka komgogodla
• I-Multiple sclerosis
• Ukulimala komgogodla noma ukucindezela
• Ukuphuka komgogodla
• Isimila somgogodla

Khuluma nomhlinzeki wakho ngemibuzo yakho nokukhathazeka kwakho.

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

Kuphephile futhi ukuthi kwenziwe i-MRI ngesikhathi sokukhulelwa. Ayikho imiphumela emibi noma izinkinga eziye zafakazelwa.

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 nokuthi ucezu lwensimbi ngaphakathi komzimba wakho luhambe noma lushintshe. Ngezizathu zokuphepha, ngicela ungalethi noma yini equkethe insimbi egumbini lesithwebuli.
