Ukuskena kwe-Lumbar MRI

Iskena se-lumbar magnetic resonance imaging (MRI) sisebenzisa amandla avela kumazibuthe aqinile ukudala izithombe zengxenye engezansi yomgogodla (i-lumbar spine).

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.

Izivivinyo ezihlobene zifaka:

• Ukuskena kwe-MRI yomlomo wesibeletho (i-MRI yentamo)
• I-MRI

Uzogqoka ingubo yasesibhedlela noma izingubo ngaphandle kwezinsimbi noma uziphu (njengezikibha zezithukuthuku nesikibha). Qiniseka ukuthi ukhumula iwashi lakho, ubucwebe namawashi. Ezinye izinhlobo zensimbi zingadala ukufiphala kwezithombe.

Uzolala etafuleni elincane elingena kushubhu enkulu efana nomhubhe.

Ezinye izivivinyo zidinga udayi okhethekile (umehluko). Isikhathi esiningi, uzoluthola udayi ngomthambo (IV) osesandleni noma engalweni ngaphambi kokuhlolwa. Ungathola futhi udayi 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 ukulala unganyakazi njengoba 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 ongawasebenzisa ukusiza isikhathi sidlule.

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

Ungadinga i-lumbar MRI uma une:

• Ubuhlungu obuphansi emuva noma okhalo obungehli kangcono ngemuva kokwelashwa
• Ubuthakathaka bomlenze, ukuba ndikindiki, noma ezinye izimpawu ezingathuthuki noma ezimbi kakhulu

Umhlinzeki wakho angaphinde a-ode i-MRI ye-lumbar uma une:

• Ubuhlungu beqolo nomkhuhlane
• Ukukhubazeka kokuzalwa komgogodla ophansi
• Ukulimala noma ukuhlukumezeka emgogodleni ophansi
• Ubuhlungu obuphansi emuva kanye nomlando noma izimpawu zomdlavuza
• I-Multiple sclerosis
• Izinkinga zokulawula noma ukukhipha isinye sakho
• I-Diski herniation

Umphumela ojwayelekile usho ukuthi umgogodla wakho nezinzwa eziseduze zibukeka zilungile.

Isikhathi esiningi, imiphumela engajwayelekile ibangelwa:

• I-disk ye-Herniated noma "eshibhile" (i-lumbar radiculopathy)
• Ukuncipha kwekholomu yomgogodla (i-spinal stenosis)
• Ukugqoka okungavamile emathanjeni nakuqwanga emgogodleni (spondylitis)

Eminye imiphumela engajwayelekile ingabangelwa:

• Izinguquko ezizenzakalelayo ngenxa yeminyaka
• I-Ankylosing spondylitis, uhlobo lwe-arthritis
• Ukutheleleka kwamathambo
• I-Cauda equina syndrome
• Ukwephuka komhlane ongezansi ngenxa ye-osteoporosis
• Ukuvuvukala kwediski (i-diskitis)
• Ithumba lomgogodla
• Ukulimala komgogodla
• Isimila somgogodla
• ISyringomyelia

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. Ukusabela okweqile kulo dayi 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 ezinye izingcezu zensimbi ngaphakathi komzimba wakho zihambe noma zigudluke. Ngezizathu zokuphepha, ngicela ungalethi noma yini equkethe insimbi egumbini lesithwebuli.
