Kujambula kwa maginito: ndi chiyani, ndi chiyani komanso momwe amachitira

Zamkati

• Ndi chiyani
• Momwe zimachitikira
• Mitundu ya MRI

Kujambula kwa maginito (MRI), komwe kumatchedwanso kuti magnetic magnetic resonance imaging (NMR), ndimayeso azithunzi omwe amatha kuwonetsa ziwalo zamkati mwa ziwalozo ndikutanthauzira, ndikofunikira kudziwa zovuta zamatenda osiyanasiyana, monga zotupa, zotupa, kusintha kwa malo kapena kuvulala kwina kwa ziwalo zamkati.

Kuti ayesere, makina akulu amagwiritsidwa ntchito, omwe amapanga zithunzi zapamwamba kwambiri za ziwalo zamkati pogwiritsa ntchito maginito, zomwe zimapangitsa kuti ma molekyulu amthupi agwedezeke, agwidwa ndi chipangizocho ndikusamutsidwa pakompyuta. Kuyezetsa kumatenga pafupifupi mphindi 15 mpaka 30 ndipo, nthawi zambiri, palibe kukonzekera kofunikira, ngakhale kungakhale kofunikira kugwiritsa ntchito kusiyanitsa, nthawi zina, kudzera mu jakisoni wa mankhwala kudzera mumitsempha.

Makina a MRI

Chithunzithunzi chamaginito cha chigaza

Ndi chiyani

Kujambula kwa maginito kumawonetsedwa pazochitika zotsatirazi:

• Dziwani matenda amitsempha, monga Alzheimer's, chotupa chaubongo, multiple sclerosis kapena stroke, mwachitsanzo;
• Onetsetsani kutupa kapena matenda muubongo, misempha kapena mafupa;
• Dziwani zovulala zaminyewa, monga tendonitis, kuvulala kwa mitsempha, zotupa, monga chotupa cha Tarlov kapena ma disc a herniated, mwachitsanzo;
• Kupeza misa kapena zotupa m'ziwalo za thupi;
• Onetsetsani kusintha kwa mitsempha ya magazi, monga kutaya magazi kapena kuundana.

Ndikofunika kusamala musanayese mayeso, chifukwa sipangakhale mtundu wina uliwonse wazitsulo pafupi ndi maginito azida, monga zikhomo za tsitsi, magalasi kapena zovala, motero kupewa ngozi. Pachifukwa chomwechi, kuyezetsa kumeneku ndikotsutsana kwa anthu omwe ali ndi mtundu uliwonse wamankhwala, zopangira zida zopangira zida zamagetsi kapena zikhomo zachitsulo zomwe zimayikidwa m'thupi.

Kuphatikiza pa zithunzithunzi zabwino zopangidwa ndi kujambula kwa maginito, mwayi wina ndikosagwiritsa ntchito ma radiation kuti mupeze zotsatira, mosiyana ndi computed tomography. Mvetsetsani kuti ndi chiyani komanso kuti CT scan ikufunika.

Momwe zimachitikira

Kujambula kwamtundu wamaginito nthawi zambiri kumakhala pakati pa 15 mpaka 30 mphindi, ndipo kumatha mpaka maola awiri kutengera dera lomwe liziwunikiridwa. Pachifukwa ichi, ndikofunikira kukhalabe mkati mwa chipangizocho chomwe chimatulutsa mphamvu yamaginito, ndipo sichimapweteka, komabe, ndikofunikira kuti musasunthe panthawiyi, chifukwa mayendedwe aliwonse amatha kusintha mayeso.

Mwa anthu omwe sangathe kuyimirira, monga ana, anthu omwe ali ndi claustrophobia, dementia kapena schizophrenia, mwachitsanzo, kungakhale kofunikira kuyesa mayeso ndi sedation kuti agone, apo ayi mayesowo sangakhale othandiza.

Kuphatikiza apo, nthawi zina, kungakhale kofunikira kuyika zosiyana pamitsempha ya wodwalayo, monga Gallium, chifukwa ndi njira yodziwira kutanthauzira kwakukulu kwa zithunzizo, makamaka kuwonetsa ziwalo kapena mitsempha yamagazi.

Mitundu ya MRI

Mitundu ya MRIs imadalira tsamba lomwe lakhudzidwa, lomwe limafala kwambiri:

• Kujambula kwamaginito kwam'chiuno, pamimba kapena pachifuwa: imagwira ntchito yotenga zotupa kapena unyinji m'ziwalo monga chiberekero, matumbo, thumba losunga mazira, Prostate, chikhodzodzo, kapamba, kapena mtima, mwachitsanzo;
• Kujambula kwamatsenga kwa chigaza: Amathandizira kuwunika kusokonekera kwa ubongo, kutuluka mwazi kwamkati, matenda am'magazi, zotupa zamaubongo ndi kusintha kwina kapena matenda muubongo kapena zotengera zake;
• Nthenda ya MRI: amathandiza kuzindikira mavuto a msana ndi msana, monga zotupa, kuwerengetsa, ma hernias kapena zidutswa za mafupa, zitasweka - Onani momwe mungazindikire arthrosis mumsana, mwachitsanzo;
• MRI yamafundo, monga phewa, bondo kapena bondo: Imathandizira kuwunika ziwalo zofewa mkati mwa olumikizana, monga bursa, tendon ndi ligaments.

Kujambula kwa maginito ndiko, kuyesayesa kwabwino kwambiri kuti tione ziwalo zofewa za thupi, komabe, sizimawonetsedwa kuti zimayang'anira zotupa m'malo olimba, monga mafupa, pokhala, poyeserera ngati mayeso a x-ray kapena computed tomography yowonetsedwa kwambiri., mwachitsanzo.
