MRI (magnetic resonance imaging) inzira yekuongororwa nhengo nemaviri, izvo mumatambudziko akawanda zvakakosha zvikuru pakugadzira kunyatsoongorora uye kurondedzera kurapwa. Iyo nzira inoita kuti zvikwanise kuwana mufananidzo wakajeka, unobvumira kuzarura zviratidzo zviduku zvikuru zvehutano hwehutano.
Kazhinji kacho, MRI inoshandiswa kuongororwa nhengo dzenheyo yenheyo, musculoskeletal system, nhengo dzomukati, musana. Kutaridzika kunokonzerwa nekuyera kwemashoko emagetsi ekugadzirisa maatomu ehydrojeni mushure mekuita kwechiito chavo nemagetsi emagetsi mumhepo yakasimba yakasimba. Idzidziso yemhando yeyo nzira inowedzera nekushandiswa kwevashumiri vanosiyana.
Icho chirongwa cheMRI chinokuvadza here?
Magnetic resonance imaging inonzi haina chakaipa kumitambo yemuviri, iyo inosimbiswa neongororo dzakawanda. Asi pasinei neizvi, pane zvimwe zvinopesana nezvinoitwa, saka zvakakosha kuita MRI chete maererano nezviratidzo zvechiremba uye funga nezvekuchengetedzwa kwehutano.
Inofanira kunzwisiswa kuti zvinopesana neMRI hazvibatanidzi kune zvinokonzera kukuvadza zvinokonzerwa nemugadziro, asi kumunhu mumwe nemuviri wehutano uye zvikanganiso zvine chokuita nekudiwa kwekugara munzvimbo yakavharwa pasi pekuita kwe magnetic field. Izvi zvinokonzerwa nemushumo wemunda pane zvigadzirwa zvemidziyo, zvemagetsi nemagetsi zvinogona kuwanikwa mumuviri womunhu. Kugadzirwa kwemasimba kunogona kutungamirira mukuvhiringidzwa mubasa ravo, kushanduka.
Contraindications kuMRI
Zvose zvinokonzera, iyo iyo maginetic resonance imaging inenge isisakwanisi, inopatsanurwa kuva mapoka maviri: hama uye zvachose zvinopesana. Kuwirirana kunopesana ndizvo zvikonzero izvo zvinogona kurongerwa, asi nemimwe mitemo. Kuvapo kwekupikisa kwakakwana kunorambidza iyi nzira yekuongorora, iyo isingagoni kubviswa nokusingaperi kana kwenguva refu.
Saka, zvinopesana zvinoreva MRI ndezvi:
- Decompensated heart failure ;
- mimba (yekutanga katatu);
- insulini pamapu;
- mafungiro emwoyo mavheti;
- hemostatic clips;
- vanosimudzira sangano remanzwi;
- claustrophobia (pakuongorora mumugwagwa tomographs);
- zvidhori pamuviri, zvakagadzirwa nesimbi-ine colorants;
- kazhinji yakaoma mamiriro ezvinhu omurwere.
Zvinyorwa zvisinganzwisisiki zveMRI zvinotevera:
- kuvapo kwe pacemaker;
- akagadza Ilizarov's apparatus;
- mashizha makuru esimbi, ferromagnetic fragments;
- kuiswa kwepakati nzeve;
- asingashandisi hemostatic mifananidzo yakagadzirwa nesimbi.
Izvo zvinopesana pamusoro apa zvinoreva MRI yemusoro (uropi), musana , mimba, mvere dzemawere uye dzimwe nzvimbo dzomuviri. Kana murwere asina chaanopesana nekudzidza, MRI inogona kudzokororwa kakawanda.
Contraindications kune MRI nechinopesana
Mune zvimwe zviitiko, MRI inotarisirwa nekushandiswa kwekusiyanisa - imwe mishonga inonyatsotarisirwa mukati uye ichibvumira "kupenya" nhengo dzomukati. Sezvo mutemo, maitiro akasiyana-siyana haapi kukonzera kukanganiswa kwezvirwere nemigumisiro, hazvina kuipa kwemuviri. Nokudaro, zvinopesana nemutemo weMRI nemafambisi akasiyana-siyana zvinosanganisira chete mamiriyoni ekutanga ekudzivirira (panguva ino, fetus inonyanya kunetseka), uyewo kusagadzikana kwevamwe zvikamu zveparanisi.
