Kuvandudzwa kwemishonga yekuongororwa ikozvino kunokubvumira kuti ugadzire chirwere kana chirwere mumatambo ekutanga. Izvi zvinoshanda kunyange kumamiriro ezvinhu akaoma akadaro emuviri wemunhu sehuropi hwemunhu. Pfungwa yekucheka-ne-yakatarisa kuongorora inobva pane nzira dzeCCT uye MRI zvidzidzo zvehuropi. Uku ndiko kufanana kwavo kukuru. Ngatitsvakei musiyano uri pakati pe CT uye MRI yeuropi, uyewo izvo zvinobudirira uye zvakajeka kupfuura MRI kana CT.
Kusiyana pakati peMRI uye CT yeuropi
Kana kutaura kune vose, zvino pakati pekuongororwa kwehuropi neCCT uye MRI kune kusiyana kwakakosha, kunosanganisira:
- teknolojia yekushandisa;
- chiyero chekunzwisisa kwechigadzirwa.
Chiito chekombiyuta tomograph inotarirwa ne-x-ray mihizha, inotungamirirwa pamatumbu, ichipa pfungwa yehuviri hwehupenyu, huwandu hwayo. CT - chigadziri chinotenderera chakakosha-mutumbi wemurwere, zvichibereka chifananidzo chechirwere chiri kubviswa (munyaya ino, uropi) mumagariro akasiyana. Zvikamu zvakawanikwa panguva yekuongororwa zvakapfupikiswa, zvichishandurwa pamakombiyuta, uye chigumisiro chekupedzisira chinopiwa, icho chinoshandurwa nenyanzvi mumunda.
MRI inopesana pakuti basa rechigadzirwa racho raisanganisira simba risina simba remasimba. Nokuita maatomu e-hydrogen, vanofananidza zvikamu izvi zvakaenzana nechinangwa chemagnetic field. Radiyo-frequency pulse inogadzirwa nemutambo inofanirwa kune magnetic field, kudengenyeka kwemasero resonate, uye izvi zvinoita kuti zvikwanise kuronga mifananidzo yakawanda. Mazuva ano MR scanners vane ruvara rwakasununguka, izvo zvinonyanya kukosha kuvarwere vanotambura ne claustrophobia.
Zviratidzo zvekugadzwa kweCCT uye MRI yeuropi
Kune vavarwere vanogoverwa kunzira yekuongororwa kweuropi, mubvunzo unokosha zvikuru: chii chiri nani kupfuura MRI kana CT scan? Funga zvose zvirwere zvekuongororwa kubva panzvimbo yechiremba wezvokurapa.
Kushandisa MRI, zviri nani kudzidza zvinyoro zviduku (misumbu, midzi yeropa, uropi, intervertebral disks), uye CT inonyanya kushandiswa pakudzidza maitiro akaoma (mapfupa).
MRI inofanirwa ku:
- hutachiona hwemu membrane hweuropi;
- soft tissue lesions;
- kunyunyuta kwekudzimba;
- kuputika kwehutano hwehuputi zvichibva pakurova , sclerosis, nezvimwe;
- kuchinja kusina kunaka mumishonga inoputika, pituitary gland.
MRI inotsanangurwawo kuti isasarirwe nezvinhu zvinonzi radiopaque, iyo inobatanidzwa mukombomusi tomography. Chinhu chinonyanya kukosha cheMRI ndechokuti hapana mazairo emunharaunda. Izvi ndizvo zvinoita kuti nzira yacho igare yakachengeteka kuvakadzi vane pamuviri (kunze kwekutanga kwevatatu) uye vakadzi vanokanganisa, pamwe chete nevana vekutanga uye vezera remakore.
Panguva imwecheteyo, MRI inopesana nemunhu ane michina yesimbi, mapiritsi, mhepo yakasvibirira, nezvimwewo.
CT inopa humwe ruzivo rwakakwana pakuongorora:
- atherosclerotic kuchinja mu vascular system;
- aneurysms ;
- zvipembenene zvemapfupa emapfupa, mapapiro eparanasal, maziso ezviso;
- matambudziko emakristani anokonzera zvivako zveuropi.
Kana tikatarisa maitiro maviri kubva pane imwe nguva, CT yekuongorora imwe chikamu chemuviri inotora kwemaminitsi gumi, nepo MRI scan inotora anenge maminitsi makumi matatu.
Pane musiyano mune zvekutsvaga kwekutsvakurudza. Computer tomography yeuropi inodhura zvikuru, uye mari ye magnetic resonance imaging, zvakakosha, yakakwirira. Uyezve, iyo yakanyanya kukwana uye inodhura chidimbu cheMRI, iyo inowedzera kunaka kwezvifananidzo, mari yakawanda iyo inofanirwa kubhadhara iyo nzira yekuongorora.
