MRI

Sesepa sa "magnetic resonance imaging" (MRI) ke teko ea litšoantšo e sebelisang limakete tse matla le maqhubu a seea-le-moea ho etsa litšoantšo tsa 'mele. Ha e sebelise mahlaseli a kotsi (x-ray).

Litšoantšo tse le 'ngoe tsa MRI li bitsoa lilae. Litšoantšo li ka bolokoa ka har'a komporo kapa tsa hatisoa ka filimi. Teko e le 'ngoe e ka hlahisa litšoantšo tse likete.

Mefuta e fapaneng ea MRI e kenyelletsa:

• MRI ea mpeng
• Cervical MRI
• MRI ea sefuba
• MRI ea Cranial
• MRI ea pelo
• Lumbar MRI
• MRI ea 'mele
• MRA (MR Angiography)
• MRV (MR Boemo ba Litaba)

U ka kopuoa ho apara moaparo oa sepetlele kapa liaparo tse se nang li-zipper kapa li-snaps (joalo ka borikhoe le sekipa). Mefuta e meng ea tšepe e ka baka litšoantšo tse lerootho.

U tla robala tafoleng e moqotetsane, e kenang ka har'a skena se seholo se bōpehileng joaloka kotopo.

Litlhahlobo tse ling li hloka dae e khethehileng (phapang). Boholo ba nako, dae e tla fanoa ka mothapo (IV) letsohong la hao kapa forearm pele ho tlhahlobo. Dae e thusa radiologist ho bona libaka tse ling ka ho hlaka.

Lisebelisoa tse nyane, tse bitsoang li-coil, li ka beoa ho potoloha hlooho, letsoho, kapa leoto, kapa libakeng tse ling tse ithutoang. Tsena li thusa ho romella le ho amohela maqhubu a seea-le-moea, le ho ntlafatsa boleng ba litšoantšo.

Nakong ea MRI, motho ea sebelisang mochini o tla u shebella a le kamoreng e 'ngoe. Teko e nka metsotso e ka bang 30 ho isa ho e 60, empa e ka nka nako e teletsana.

O ka kopuoa ho se je kapa ho noa letho lihora tse 4 ho isa ho tse 6 pele ho scan.

Bolella mofani oa tlhokomelo ea bophelo haeba u tšaba libaka tse haufi (na claustrophobia). U ka fuoa moriana ho u thusa hore u tšoaroe ke boroko le ho se tšoenyehe, kapa mofani oa hau a ka fana ka maikutlo a MRI e bulehileng, moo mochini o seng haufi le 'mele.

Pele ho tlhahlobo, bolella mofani oa hau haeba u na le:

• Li-valve tsa pelo tsa maiketsetso
• Likoto tsa aneurysm tsa boko
• Heart defibrillator kapa pacemaker
• Lisebelisoa tsa tsebe ea ka hare (cochlear)
• Lefu la liphio kapa dialysis (o kanna oa se khone ho fumana phapang)
• Manonyeletso a maiketsetso a sa tsoa beoa
• Masapo a methapo
• O sebelitse ka tšepe nakong e fetileng (o kanna oa hloka liteko ho lekola likotoana tsa tšepe mahlong a hau)

Hobane MRI e na le limakete tse matla, lisebelisoa tsa tšepe ha lia lumelloa ho kena ka phapusing e nang le sekena sa MRI:

• Lintho tse kang mabenyane, lioache, likarete tsa mokitlane le lithuso tsa kutlo li ka senyeha.
• Lipene, mekotla e mekotla le likhalase tsa mahlo li ka fofa ka phapusing.
• Lithakhisa, lithipa tsa moriri, li-zipper tsa tšepe le lintho tse ling tsa tšepe li ka sotha litšoantšo.
• Mosebetsi oa meno o tlosoang o lokela ho ntšoa pele ho scan.

Tlhahlobo ea MRI ha e bake bohloko. Haeba u thatafalloa ke ho bua leshano kapa u tšohile haholo, u ka fuoa moriana oa ho u khatholla. Motsamao o mongata o ka fifatsa litšoantšo tsa MRI mme oa baka liphoso.

Tafole e kanna ea ba thata kapa ea bata, empa u ka kopa kobo kapa mosamo. Mochini o hlahisa lerata le lerata ha o buletsoe. O ka roala lipolaka tsa tsebe ho thusa ho fokotsa lerata.

Intercom ka kamoreng eu lumella ho bua le motho neng kapa neng. Li-MRIs tse ling li na le lithelevishene le li-headphone tse khethehileng tseo u ka li sebelisang ho thusa nako hore e fete.

Ha ho na nako ea ho hlaphoheloa ntle le haeba u filoe moriana oa ho phomola. Kamora ho hlahloba MRI, u ka qalella lijo tsa hau tse tloaelehileng, tšebetso le meriana.

Ho ba le MRI hangata ho ka thusa:

• Hlahloba tšoaetso
• Tsamaisa ngaka sebakeng se nepahetseng nakong ea biopsy
• Khetholla matšoele le lihlahala, ho kenyeletsoa mofetše
• Ithute methapo ea mali

Litšoantšo tsa MRI tse nkuoeng kamora 'dae e khethehileng li fuoe' mele oa hau li ka fana ka leseli le eketsehileng ka methapo ea mali.

Magnetic resonance angiogram (MRA) ke mofuta oa monahano oa matla a khoheli o hlahisang litšoantšo tse mahlakore a mararo tsa methapo ea mali.

Sephetho se tloaelehileng se bolela hore sebaka sa 'mele se ithutoang se shebahala se tloaelehile.

Liphetho li ipapisitse le karolo ea 'mele e hlahlojoang le mofuta oa bothata. Mefuta e fapaneng ea lisele e khutlisa matšoao a fapaneng a MRI. Mohlala, lisele tse phetseng hantle li khutlisa lets'oao le fapaneng hanyane ho feta lisele tsa mofetše. Ikopanye le mofani oa hau ka lipotso le lintho tse u tšoenyang.

MRI ha e sebelise mahlaseli a kotsi. Ha ho litla-morao tse tsoang ho makenete le maqhubu a seea-le-moea a tlalehiloeng.

Mofuta o tloaelehileng oa phapano (dae) o sebelisitsoeng ke gadolinium. Sesebelisoa sena ho nahanoa hore se bolokehile ka kakaretso ho batho ba bangata. Gadolinium e bolokiloe bokong le litho tse ling (ho kenyeletsoa letlalo ho batho ba nang le lefu la liphio) kamora ho sebelisoa. Maemong a sa tloaelehang, tšenyo ea litho le letlalo e etsahetse ho bakuli ba nang le ho hloleha ha liphio pele ho nako Bolella mofani oa hau pele ho tlhahlobo haeba u na le mathata a liphio.

Matla a matla a khoheli a entsoeng nakong ea MRI a ka baka li-pacemaker tsa pelo le lisebelisoa tse ling hore le tsona li se ke tsa sebetsa. Limenete li ka baka sengoathoana sa tšepe kahare ho mmele oa hau ho sutha kapa ho sutha.
