MRI

Kujambula kwa maginito oyeserera (MRI) ndiyeso yojambula yomwe imagwiritsa ntchito maginito amphamvu ndi mafunde amawailesi kupanga zithunzi za thupi. Sigwiritsa ntchito ma radiation (x-ray) ionizing.

Zithunzi za MRI zosakwatiwa zimatchedwa magawo. Zithunzizo zimatha kusungidwa pakompyuta kapena kusindikizidwa pafilimu. Kuyesa kumodzi kumatha kupanga zithunzi masauzande ambiri.

Mitundu yosiyanasiyana ya MRI ndi iyi:

• M'mimba mwa MRI
• Cervical MRI
• Chifuwa cha MRI
• Cranial MRI
• MRI ya Mtima
• Lumbar MRI
• Pelvic MRI
• MRA (MR Angiography)
• MRV (MR Kujambula)

Mutha kupemphedwa kuvala chovala chaku chipatala kapena zovala zopanda zipi kapena zingwe (monga thukuta ndi t-sheti). Mitundu ina yazitsulo imatha kubweretsa zithunzi zosalongosoka.

Mudzagona pa tebulo laling'ono, lomwe limalowa mu sikani yayikulu yooneka ngati ngalande.

Mayeso ena amafuna utoto wapadera (kusiyanitsa). Nthawi zambiri, utoto umaperekedwa kudzera mu mtsempha (IV) womwe uli m'manja mwanu kapena mkono wanu usanayezedwe. Utoto umathandiza radiologist kuwona madera ena bwino lomwe.

Zipangizo zing'onozing'ono, zotchedwa ma coil, zimatha kuyikidwa mozungulira mutu, mkono, kapena mwendo, kapena madera ena omwe angawerengedwe. Izi zimathandiza kutumiza ndi kulandira mafunde a wailesi, ndikukweza zithunzithunzi.

Pa MRI, munthu amene amagwiritsa ntchito makinawo amakuwonerani kuchokera kuchipinda china. Kuyesaku kumatha pafupifupi mphindi 30 mpaka 60, koma zimatenga nthawi yayitali.

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

Uzani wothandizira zaumoyo wanu ngati mukuwopa malo oyandikira (khalani ndi claustrophobia). Mutha kupatsidwa mankhwala okuthandizani kuti mukhale ogona komanso osakhala ndi nkhawa, kapena omwe akukuthandizani atha kunena za MRI yotseguka, pomwe makinawo sali pafupi ndi thupi.

Asanayesedwe, uzani omwe akukuthandizani ngati muli ndi:

• Mavavu amtima opangira
• Zithunzi za ubongo
• Mtetezi wamtima kapena pacemaker
• Zodzala zamakutu zamkati (cochlear)
• Matenda a impso kapena dialysis (mwina simungathe kusiyanitsa)
• Zowayika posachedwa
• Mitsempha ya mitsempha
• 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:

• Zinthu monga zodzikongoletsera, mawotchi, ma kirediti kadi, ndi zothandizira kumva zimatha kuwonongeka.
• Zolembera, zotchinga matumba, ndi magalasi amaso zitha kuwuluka mchipinda chonse.
• 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. Ngati zikukuvutani kugona kapena mukuchita mantha kwambiri, mutha kupatsidwa mankhwala oti akupumulitseni. Kuyenda kwambiri kumatha kusokoneza zithunzi za MRI ndikupanga zolakwika.

Gome likhoza kukhala lolimba kapena lozizira, koma mutha kupempha bulangeti kapena pilo. Makinawo amapanga phokoso lalikulu ndikumveketsa mukatsegulidwa. Mutha kuvala mapulagi amakutu kuti muchepetse phokoso.

Intakomu m'chipindamo imakupatsani mwayi wolankhula ndi munthu nthawi iliyonse. Ma MRIs ena amakhala ndi ma TV komanso mahedifoni apadera omwe mungagwiritse ntchito kuti muthane ndi nthawi.

Palibe nthawi yochira, pokhapokha mutapatsidwa mankhwala oti musangalale. Pambuyo pakuwunika kwa MRI, mutha kuyambiranso zakudya zanu zachizolowezi, zochita zanu, ndi mankhwala.

Kukhala ndi MRI kumatha kuthandizira:

• Dziwani za matenda
• Atsogolereni dokotala kumalo oyenera panthawi yolemba
• Dziwani misala ndi zotupa, kuphatikiza khansa
• Phunzirani mitsempha ya magazi

Zithunzi za MRI zojambulidwa utoto wapadera (kusiyanitsa) zimaperekedwa mthupi lanu zimatha kukupatsirani zambiri pamitsempha yamagazi.

Maginito a maginito angiogram (MRA) ndi mawonekedwe azithunzi zamaginito omwe amapanga zithunzi zazithunzi zitatu za mitsempha yamagazi.

Zotsatira zabwinobwino zimatanthauza kuti dera lomwe munthu amaphunzira limakhala lachilendo.

Zotsatira zimadalira gawo la thupi lomwe likufufuzidwa komanso mtundu wa vutoli. Mitundu yosiyanasiyana imabweretsanso mitundu yosiyanasiyana ya ma MRI. Mwachitsanzo, minofu yathanzi imatumizanso chizindikiro chosiyana pang'ono ndi minofu ya khansa. Funsani omwe akukuthandizani ndi mafunso aliwonse komanso nkhawa.

MRI sigwiritsa ntchito ma radiation. Palibe zoyipa zomwe zimachitika kuchokera kumaginito ndi mafunde a wailesi omwe adanenedwa.

Mtundu wosiyana kwambiri (utoto) womwe umagwiritsidwa ntchito ndi gadolinium. Izi zimaganiziridwa kuti nthawi zambiri zimakhala zotetezeka kwa anthu ambiri. Gadolinium imasungidwa muubongo ndi ziwalo zina (kuphatikizapo khungu mwa anthu omwe ali ndi matenda a impso) mutagwiritsa ntchito. Nthawi zambiri, kuwonongeka kwa ziwalo ndi khungu kwachitika mwa odwala omwe ali ndi vuto la impso.

Mphamvu yamaginito yomwe imapangidwa mu MRI imatha kupangitsa kuti mtima uzikhala wolimba komanso zopangira zina kuti zisagwire ntchito. Maginito amathanso kupangira chitsulo mkati mwathupi kusuntha kapena kusintha.
