Knee MRI scan

Kujambula kwa bondo la MRI (magnetic resonance imaging) kumagwiritsa ntchito mphamvu kuchokera kumaginito amphamvu kuti apange zithunzi za bondo limodzi ndi minofu ndi minyewa.

MRI 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). Chonde chotsani mawotchi anu, magalasi, zodzikongoletsera, ndi chikwama. Mitundu ina yazitsulo 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 (IV) m'manja mwanu kapena m'manja musanayezeke. Nthawi zina, utoto umalowetsedwa mu cholumikizira. 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. Kungakhale mokweza. Katswiri angakupatseni mapulagi a khutu ngati angafunike.

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.

Wothandizira anu atha kuyitanitsa mayeso ngati muli ndi:

• Zotsatira zosazolowereka pa x-ray kapena fupa
• Kumverera kuti bondo lanu likupereka mu mawondo
• Kupanga kwamadzimadzi olowa kumbuyo kwa bondo (Baker cyst)
• Kutulutsa kwamadzimadzi mu bondo limodzi
• Kutenga kwa bondo
• Kuvulala kwa bondo
• Kupweteka kumapazi ndi malungo
• Kutseka bondo mukamayenda kapena kuyenda
• Zizindikiro za kuwonongeka kwa bondo, cartilage, kapena ligaments
• Kupweteka kwamaondo komwe sikumakhala bwino ndi chithandizo
• Kusakhazikika kwa bondo

Muthanso kukhala ndi mayesowa kuti muwone momwe mukuyendera pambuyo pochitidwa opaleshoni ya mawondo.

Zotsatira zabwinobwino zikutanthauza kuti bondo lanu limawoneka bwino.

Zotsatira zosazolowereka zimatha kukhala chifukwa chakung'ambika kapena kutuluka kwa mitsempha mu bondo.

Zotsatira zachilendo zitha kukhalanso chifukwa cha:

• Kusintha kapena kusintha komwe kumachitika ndi ukalamba
• Meniscus kapena cartilage kuvulala
• Nyamakazi ya bondo
• Avascular necrosis (yotchedwanso osteonecrosis)
• Chotupa cha mafupa kapena khansa
• Fupa losweka
• Kupanga kwamadzimadzi olowa kumbuyo kwa bondo (Baker cyst)
• Matenda m'mafupa (osteomyelitis)
• Kutupa
• Kuvulala kwa bondo

Lankhulani ndi omwe amakupatsani ngati muli ndi mafunso kapena nkhawa.

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

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 zidutswa zazitsulo 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 bondo ndi awa:

• Kujambula kwa CT kwa bondo
• Bondo x-ray

MRI - bondo; Kujambula kwa maginito - bondo

• Kukonzanso kwa ACL - kutulutsa
