Sakani MRI

Kujambula kwa MRI (magnetic resonance imaging) kumagwiritsa ntchito maginito amphamvu kupanga zithunzi zakumtunda ndi kumunsi. Izi zingaphatikizepo chigongono, dzanja, manja, zala, ndi minofu yozungulira ndi ziwalo zina.

Sigwiritsa ntchito radiation (x-ray).

Zithunzi za MRI zosakwatiwa zimatchedwa magawo. Zithunzizo zimatha kusungidwa pakompyuta kapena kusindikizidwa pafilimu. Kuyesa kumodzi kumatulutsa zithunzi zambiri.

Mudzavala chovala cha kuchipatala kapena zovala zopanda zipi zachitsulo kapena zingwe (monga thukuta ndi t-sheti). Onetsetsani kuti mwavula wotchi yanu, zodzikongoletsera, ndi chikwama. Mitundu ina yachitsulo imatha kubweretsa zithunzi zosalongosoka.

Mudzagona pa tebulo laling'ono lomwe limalowa mu sikani yayikulu yofanana.

Mayeso ena amagwiritsa ntchito utoto wapadera (kusiyanitsa). Nthawi zambiri, mutha kupaka utoto kudzera mumitsempha m'manja mwanu kapena m'manja musanayesedwe. Utoto umathandiza radiologist kuwona madera ena bwino lomwe.

Pa MRI, munthu amene amagwiritsa ntchito makinawo amakuwonerani kuchokera kuchipinda china. Mayeso nthawi zambiri amatenga mphindi 30 mpaka 60, koma amatenga nthawi yayitali.

Mutha kupemphedwa kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 musanajambulitse.

Uzani wothandizira zaumoyo wanu ngati mukuwopa malo otsekedwa (khalani ndi claustrophobia). Mutha kupatsidwa mankhwala okuthandizani kuti mukhale ogona komanso osakhala ndi nkhawa. Wopereka wanu atha kunena za MRI "yotseguka", pomwe makinawo samayandikira thupi.

Asanayesedwe, uzani omwe akukuthandizani ngati muli ndi:

• Zithunzi za ubongo
• Mitundu ina yamavavu amtima wopangira
• Mtetezi wamtima kapena pacemaker
• Zodzala zamakutu zamkati (cochlear)
• Matenda a impso kapena dialysis (mwina simungathe kusiyanitsa)
• Zowayika posachedwa
• Mitundu ina yamatenda am'mimba
• Ankagwira ntchito ndi chitsulo m'mbuyomu (mungafunike kuyesa kuti muwone ngati zidutswa zazitsulo zili m'maso mwanu)

Chifukwa MRI imakhala ndi maginito amphamvu, zinthu zachitsulo siziloledwa kulowa mchipindacho ndi sikani ya MRI:

• Zolembera, zotchinga matumba, ndi magalasi amaso zitha kuwuluka mchipinda chonse.
• Zinthu monga zodzikongoletsera, mawotchi, ma kirediti kadi, ndi zothandizira kumva zimatha kuwonongeka.
• Pini, zikhomo zopangira tsitsi, zipi zachitsulo, ndi zinthu zina zachitsulo zofananira zimatha kupotoza zithunzizi.
• Ntchito yochotsa mano iyenera kutulutsidwa pang'ono isanakwane.

Kuyeza kwa MRI sikumapweteka. Muyenera kunama. Kuyenda kwambiri kumatha kusokoneza zithunzi za MRI ndikupanga zolakwika.

Gome likhoza kukhala lolimba kapena lozizira, koma mutha kufunsa bulangeti kapena pilo. Makinawo amapanga phokoso lalikulu ndikumveketsa akamatsegulidwa. Mutha kuvala mapulagi amakutu kuti muthane ndi phokoso.

Intakomu m'chipindamo imakupatsani mwayi wolankhula ndi munthu nthawi iliyonse. Ma MRIs ena amakhala ndi ma televizioni komanso mahedifoni apadera kuti athandizire kupitako.

Palibe nthawi yochira, pokhapokha mutapatsidwa mankhwala oti musangalale. Mukatha kusanthula MRI, mutha kubwereranso ku zomwe mumadya, zochita zanu, komanso mankhwala anu.

Kuyesaku kumapereka zithunzi zomveka bwino za magawo a mkono omwe ndi ovuta kuwona bwino pazithunzi za CT.

Wothandizira anu atha kuyitanitsa mayeso ngati muli ndi:

• Unyinji womwe ungamveke pakuwunika kwakuthupi
• Kupeza kwachilendo pa x-ray kapena fupa
• Kupweteka kwa mkono ndi mbiri ya khansa
• Kupweteka kwa mkono kapena dzanja komwe sikumakhala bwino ndi chithandizo
• Matenda a mafupa (osteomyelitis)
• Kupweteka kwa mafupa ndi malungo
• Fupa losweka
• Kuchepetsa kuyenda kapena "kutseka" cholumikizira dzanja kapena chigongono
• Kufiira kapena kutupa kwa dzanja kapena zigongono
• Kuvulala kwa karoti ndi mitsempha

Zotsatira zabwinobwino zikutanthauza kuti mkono wanu ukuwoneka bwino.

Zotsatira zachilendo zitha kukhala chifukwa cha:

• Zosintha zosintha chifukwa cha msinkhu
• Chilonda
• Bursitis ya chigongono kapena dzanja
• Wathyoka fupa kapena wovulala
• Ganglion cyst m'manja
• Matenda m'mafupa
• Ligament, tendon, kapena cartilage kuvulala m'manja kapena m'zigongono
• Kuwonongeka kwa minofu
• Osteonecrosis (avascular necrosis)
• Chotupa kapena khansa m'mafupa, minofu, kapena zofewa

Lankhulani ndi omwe amakupatsani ngati muli ndi mafunso komanso nkhawa.

MRI ilibe ma radiation. Sipanakhalepo zotsatira zoyipa kuchokera kumaginito ndi mafunde a wailesi.

Ndizotetezanso kuti MRI izichita nthawi yapakati. Palibe zovuta kapena zovuta zomwe zatsimikiziridwa.

Mtundu wosiyana kwambiri (utoto) womwe umagwiritsidwa ntchito ndi gadolinium. Ndi otetezeka kwambiri. Thupi lawo siligwirizana ndi zinthu ndizochepa. Komabe, gadolinium itha kuvulaza anthu omwe ali ndi mavuto a impso omwe amafunikira dialysis. Ngati muli ndi vuto la impso, chonde uzani omwe amakupatsani chithandizo asanayesedwe.

Mphamvu zamaginito zomwe zimapangidwa mu MRI zimatha kupangitsa kuti mtima uzikhala wolimba komanso zopangira zina kuti zisagwire ntchito. Zitha kupanganso chitsulo mkati mwathupi kusuntha kapena kusintha. Pazifukwa zachitetezo, chonde musabweretse chilichonse chomwe chili ndi chitsulo m'chipinda chojambulira.

Mayeso omwe angachitike m'malo mwa MRI ya mkono ndi awa:

• Kujambula kwa CT kwa mkono
• X-ray yolumikizana

Makina osindikizira a CT atha kusankhidwa mwadzidzidzi. Mayesowa ndi achangu kuposa MRI ndipo nthawi zambiri amapezeka mchipinda chadzidzidzi.
