Tiyeni tiphunzire za mayeso a MRI (Magnetic Resonance Imaging). Tiyeni tikambirane za tsatanetsatane popanda mantha!

Kodi munamvapo za MRI scan? Mwina dokotala wanu wakupemphani kuti muyesedwe. Kapena mwina mnzanu kapena wachibale wanu wachitapo kale. Chifukwa chake, mwina muli ndi mafunso ambiri okhudza MRI, chifukwa chake imachitidwa, komanso zomwe zimachitika pambuyo pake. Musadandaule, lero tikambirana za mayeso a MRI (Magnetic Resonance Imaging) m'njira yosavuta yomwe mungamvetse.

Kodi MRI (Magnetic Resonance Imaging) kwenikweni ndi chiyani?

Mwachidule, MRI ndi mayeso osapweteka omwe amatithandiza kuona mkati mwa matupi athu, monga ziwalo ndi minofu, momveka bwino . Imagwiritsa ntchito maginito akuluakulu, mafunde a wailesi, ndi kompyuta kuti ipange zithunzi zatsatanetsatane za mkati mwa matupi athu. Chofunika kwambiri ndichakuti sigwiritsa ntchito X-ray, kapena radiation.

Kawirikawiri, ngati munthu akufunika kuyesedwa pafupipafupi, makamaka m'malo monga ubongo, madokotala amasankha MRI iyi. Chifukwa chake ndi chakuti popeza palibe kuwala kwa dzuwa, sikubweretsa mavuto ambiri ngati kuchitidwa pafupipafupi. Tangoganizirani, pochiza matenda ena, muyenera kupitiliza kuyesedwa kuti muwone ngati matendawa akukulirakulira kapena akuchira. Pazochitika zotere, MRI ndi yothandiza kwambiri.

Kodi 'Open MRI' ndi chiyani?

Tsopano, pali mitundu iwiri ya makina a MRI. Chimodzi ndi mtundu wa 'Open MRI'. Mu izi, mumagona pabedi, ndipo pali maginito awiri athyathyathya pamwamba ndi pansi panu. Izi zimapangitsa malo akulu mbali zonse ziwiri. Anthu ena amamva kutopa akalowa mu makina ena a MRI. Kwa iwo, 'Open MRI' ndi yabwino kwambiri chifukwa siimapanikizana kwambiri.

Koma pali vuto laling'ono. Zithunzi zomwe zajambulidwa ndi makina awa a 'Open MRI' sizikumveka bwino ngati zomwe zajambulidwa ndi makina ena a 'Closed-bore MRI'. Makina a 'Closed-bore MRI' ali ndi bwalo lozungulira ndi maginito. Ali ngati chubu. Mumalowa mkati mwa chubu chimenecho. Kotero ndi chopapatiza pang'ono, ndipo palibe malo ambiri pakati pa mutu wanu ndi gawo la makina pamwambapa. Chifukwa cha izi, anthu ena angamve kusasangalala komanso mantha pang'ono. Komabe, zithunzi zabwino kwambiri zitha kujambulidwa ndi makina awa.

Ngati mukuchitidwa MRI scan ndipo mukuopa kukhala m'malo opapatiza, lankhulani ndi dokotala wanu za izi. Iye adzatha kukupatsani mankhwala ochepetsa ululu kapena ngakhale mankhwala oletsa ululu ngati pakufunika kutero.

Kodi MRI yokhala ndi 'contrast' ndi chiyani?

Pa nthawi zina zowunikira za MRI, mumapatsidwa jakisoni kakang'ono ka zinthu zosiyanitsa. Kali ndi chitsulo chosowa chotchedwa gadolinium. Zinthuzi zikalowetsedwa m'thupi lanu, zimasintha mphamvu zamaginito za mamolekyu a madzi omwe ali pafupi. Izi zimapangitsa kuti zithunzi ziwonekere bwino . Izi zimawonjezera kukhudzidwa ndi kudziwika kwa chithunzicho.

Kugwiritsa ntchito zinthu 'zosiyana' kumeneku kumawonjezera kumveka bwino kwa zinthu izi:

• Zotupa
• Matenda otupa (`Kutupa`)
• Matenda
• Momwe magazi amaperekedwera ku ziwalo zina
• Mitsempha ya magazi

Ngati MRI yanu ikufuna mtundu uwu wa zinthu zosiyanitsa, dokotala adzaika kansalu kakang'ono ('katheta wa m'mitsempha (IV line)') mu mtsempha womwe uli m'dzanja lanu kapena m'dzanja lanu. Apa ndi pomwe mankhwala amabayidwa.

Zinthu 'zosiyana' izi ndi mankhwala otetezeka . Nthawi zina zotsatirapo zazing'ono zimatha kuchitika, koma zotsatirapo zazikulu zimakhala zochepa kwambiri.

Kodi kusiyana pakati pa MRI ndi CT scan ndi kotani?

MRI (Magnetic Resonance Imaging) imagwiritsa ntchito maginito, mafunde a wailesi, ndi kompyuta kuti ipange zithunzi za mkati mwa thupi. Komabe, ma scan a CT (Computed Tomography) amagwiritsa ntchito X-ray ndi makompyuta.

Madokotala nthawi zambiri amasankha MRI m'malo mwa CT scan kuti aone minofu yofewa , yomwe si ziwalo za thupi zomwe zili ndi mafupa. MRI scans ndi yotetezekanso chifukwa ilibe ma radiation a ayoni omwe X-ray ili nawo.

Si zokhazo, koma MRI imatha kuona zinthu monga ubongo wanu, chingwe cha msana, mitsempha, minofu, mitsempha, ndi minyewa bwino kwambiri kuposa ma X-ray ndi ma CT scans wamba.

Komabe, si aliyense amene angayesedwe ndi MRI. Mphamvu yamphamvu ya maginito ya MRI imatha kusuntha zinthu zina zachitsulo m'thupi, kapena kukhudza magwiridwe antchito a zida monga pacemakers ndi mapampu a insulin. Pazochitika zotere, CT scan ndiyo njira ina yabwino kwambiri.

Kujambula kwa MRI nthawi zambiri kumakhala kokwera mtengo pang'ono kuposa X-ray kapena CT scan.

Kodi ndi chiyani chomwe chingayang'anitsidwe ndi MRI?

Tamva kuti MRI (Magnetic Resonance Imaging) imatha kujambula zithunzi zamkati mwa thupi lanu. Chifukwa chake, madokotala amatha "kuona" zinthu zambiri mkati mwa thupi lanu ndi MRI iyi, kuphatikizapo:

• Ubongo wanu ndi minofu ya mitsempha yozungulira .
• Ziwalo zomwe zili pachifuwa ndi m'mimba. Zitsanzo zake ndi mtima, chiwindi, njira ya biliary, impso, ndulu, matumbo, kapamba, ndi ma adrenal glands.
• Minofu ya m'mawere.
