Njira Yoyamba Yoyesera Yosaoneka
MRI, yomwe imadziwikanso kuti magnetic resonance imaging, ndiyeso yachipatala yopanda kupweteka yomwe imagwiritsidwa ntchito popanga zithunzi ziwiri za thupi. Njirayi imagwiritsa ntchito maginito amphamvu kuti apange zithunzi za mkati mwa thupi.
MRIs amagwiritsidwa ntchito kuti azindikire mavuto m'thupi kapena ubongo popanda opaleshoni, ndipo amatha kudziwa zolakwika kunja kwa thupi.
Yemwe Sangathe Kukhala ndi MRI
Odwala omwe ali ndi thupi lokhala ndi zitsulo, monga pacemaker kapena zipangizo za mafupa, sangathe kukhala ndi MRI pamene makina amagwiritsa ntchito magetsi amphamvu kuti apeze zithunzi zofunikira. Choletsa ichi chingagwiritsenso ntchito zinthu zina zitsulo m'thupi, monga zidutswa za zipolopolo, zitsulo zamkuwa ndi zitsulo zofanana. Izi ndi chifukwa chakuti makina amagwiritsa ntchito magetsi amphamvu kuti apange zithunzi zomwe amagwiritsidwa ntchito kuti apeze matenda ndipo maginito akhoza kukopa zitsulo zomwe ziri m'thupi.
Ngati pali funso lililonse limene wodwalayo ali nalo mtundu wa zitsulo m'thupi lawo lomwe lingathe kusokoneza MRI kuyesa wodwalayo akhoza kukhala ndi X-ray, yomwe imakhala yosonyeza zitsulo bwino, kapena akhoza kukhala ndi CT omwe sagwiritsa ntchito magetsi kuti apange zithunzi za mkati mwa thupi. Izi sizinali vuto chifukwa ambiri odwala amadziwa ngati ali ndi mtundu uliwonse wopangira; Komabe, ngati wodwalayo sakudziwa kapena sangathe kupereka mbiri yachipatala chiopsezo chotenga mawonekedwewa chikuwonekera ndithu.
Anthu omwe ali ndi titaniyamu m'thupi lawo amatha kukhala ndi MRI.
Ubwino wa MRI
Mayeso a MRI amalola gulu lachipatala kuti liwone mkati mwa thupi popanda kupanga chowombera. Chiyesochi chimakhalanso mofulumira komanso chokhoza kupanga zithunzi zomwe zatchulidwa mwatsatanetsatane. Mwachitsanzo, ngati wodwalayo ali ndi zizindikiro zolimbana ndi matenda a stroke, MRI ikhoza kuchitidwa kuyang'ana mitsempha ya magazi ya ubongo - ngakhale ziwiya zazing'ono zomwe zingakhale zovuta kuzifufuza.
Zithunzi zowonongeka za MRI zingathandizenso kupeza matenda omwe angakhudze mafupa, minofu kapena mitundu ina ya tizilombo. Ngati dokotala wanu akudandaula kuti muli ndi matenda kapena ndondomeko ya matenda, MRI ikhoza kulamulidwa pofuna kuyesa vuto. Nthaŵi zina, matendawa angapangidwe ndi MRI ndipo akhoza kuteteza kapena kusonyeza kufunikira kwa opaleshoni .
Kuwonjezera pa kusokonezeka kwa kukhalabe pamalo amodzi pamene mayesero atha, MRI siipweteka. Makina akhoza kumveka mokweza pamene akugwira ntchito, koma makutu amapezeka nthawi zambiri kwa omwe akuvutitsidwa ndi phokoso.
Palibe mankhwala opangidwa ndi makina a MRI, kotero kuopsa kwa kukhala ndi MRI sikochepa kwa wodwalayo amene alibe zitsulo m'thupi lake.
Tsegulani MRI ndi MRI Yachikhalidwe
Mu MRI yachikhalidwe, wodwalayo amaikidwa pa bedi lomwe limasuntha mkati mwa chubu, kumene MRI imatha. MRI yotseguka, chisankho kwa odwala omwe akuvutitsidwa ndi malo ang'onoang'ono kapena aakulu kwambiri, safuna kuti odwala akhale mu chubu, koma amachitika poyera.
Odwala omwe amafunikira MRI koma amakhala ndi malo ochepa nthawi zambiri amapatsidwa mankhwala kuti athe kuchepetsa nkhawa yawo isanafike.
Mitundu ya MRI
MRI ikhoza kulamulidwa kapena mosiyana. Kusiyana kwa sing'anga ndi madzi omwe amaperekedwa kudzera mu IV, ndipo akhoza kulola zithunzi zambiri kuti zipeze. Kwa odwala ambiri, MRI yopanda kusiyana imayesedwa, kenaka ndi jekeseni wa zinthu zosiyana ndi MRI yachiwiri, iyi ndi yosiyana. M'mbuyomu, anthu okhala ndi nkhono za shellfish sakanatha kusiyana ngati anali ndi ayodini. Mitundu yatsopano imatanthawuza kuti zovuta zowonongeka siziteteza kugwiritsa ntchito kusiyana.
Mbali zonse za thupi zimatha kuthandizidwa kugwiritsa ntchito zipangizo zamakono za MRI, kuphatikizapo mtima ndi ubongo.

Zitsanzo: MRI inalimbikitsidwa kuti mudziwe ngati wodwalayo akudwala chifukwa cha kupwetekedwa.
