Chii chinonzi MRI chinyorwa? Chii chinonzi chirwere cheMRI?

Kuongororwa kwezvirwere zvakawanda kunopesvedzwa zvikuru nechokwadi chokuti kunyatsoronga dambudziko kunokosha kuti uone maitiro ekunze kwemuviri, shanduko mune zvayo. Izvo zviri mumamiriro ezvinhu akadaro kuti zvakanakisisa kuongorora nzira ndeye magnetic resonance imaging (MRI).

Chii chinonzi Magnetic Resonance Imaging?

Kufungidzira kuburikidza neMRI kunowanzoonekwa nhasi, sezvo zvichibvumira kufungidzira zvingangoita nhengo dzose dzomukati uye kuratidza kuchinja kwemasimba mumatumbu nhengo; Kunyanya, mifananidzo yakavezwa yeMRI yeuropi inonyatsodzidzisa uye inobatsira zvikuru pakuona kusagadzikana kwezvinhu zvinokonzerwa nehutachiona, zvirwere (kunyanya mukana wekuona zvakanyanya mumarwadzo ane chirwere), pamwe nekurwara kwemidziyo (aneurysms kana kusagadzikana); Zvinotarisirwa kuita MRI uye mukurwara kwakanyanya kwepaniocerebral.

Kubatsirwa

Iyo nzira yeMRI inobatanidza kuratidzwa uye kuratidza, asi panguva imwechete, kuchengetedzwa kwemurwere.

Chinhu chisingaoneki cheMRI ndechekuti zvakanyatsorondedzerwa zvakajeka zvifananidzo zvemukati uye nhengo dzomukati zvinogona kuwanikwa kunze kwekushandiswa kwevashumiri vanosiyana.

Zvisinei, pane dzimwe nguva, kusimbisa kusiyanisa kunoshandiswa pakuona zvakajeka; Kunyanya, inoshandiswa mukudzidza kwehutano hwemidziyo yeperesi. Mifananidzo yeMRI yeuropi nezvakasiyana-siyana inonyatsodzidzisa, nekuputsika kwakanyanya kwepfungwa yepamusoro, sezvo ichiita kuti zvikwanise kutarisa chiyero chezvipembenene zvechikepe uye zvakaenzana zvakakosha zvekutarisa kwepfungwa.

Iyo scanner inoshanda sei?

Pachine simba rekuita magnetic oscillations, maitiro eatomu ehydrojeni anochinja, sezvo hurumende yekutenderera kwechidimbu chinokonzerwa nechikamu chemukati we hydroxy atomu inoshanduka. Apo motokari inopera, simba rinosunurwa nechokushandisa rinobviswa.

Nzira yekuongororwa yeMRI inoshanda pamusana pechiitiko che magnetic resonance. Icho chirevo chekugadzirisa zvinoshandiswa a zvinoshandiswa mukushandurwa kwemashoko eredhiyo mumufananidzo. Shanduko ye radio inoshandiswa inowanikwa kubva kune magnetic resonance spectrometer.

Nemhaka yezvinhu zveatomu e-hydrogen, izvo zvayo mumumuviri womunhu zvinosvika gumi kubva muzana, kuongororwa kwakadaro kunogona kuitika kunze kwekukanganisa kukuvadza kune utano.

Sezvo watova kugamuchira chifananidzo chakapedzwa, nyanzvi dzehuwandu hwemifananidzo dzinofananidza kuongorora mufananidzo unoguma, kuenzanisa nayo nehutano uye kuratidza hutano hwekuchinja.

Nhoroondo yeyo nzira

Izvo zvakajeka zve nyukireya magnetic resonance yakawanikwa uye yakatsanangurwa pakati pezana remakore rechimakumi maviri - muna 1946. Uye nguva yokutanga kuwana mufananidzo uchishandisa teknolojia iyi yaibvira muna 1973.

Kuongorora kunoitwa sei?

Kunze kwekunze, iyo midziyo ye magnetic resonance imaging inoratidzika seyendarira yakareba yakareba.

Paunenge uchitarisa murwere, uise mukati meimba nechepamusoro.

Sezvo nguva yemurwere akagara mukati mechigadzirwa ichi yakakwirira - kusvika pamaminitsi makumi mana, uye mune dzimwe mamiriro akaomesesa - kunyanya, mamiriro ekugara kwevarwere mu "pombi" inofanira kuva yakasununguka sezvinobvira. Pakati pechigadzirwa, magetsi nemhepo inoputika haisi yakajeka zvakakwana kuti uone kufema kufema. Panofanira kuva nebhokisi rekukurukura nemunhu anotungamirira kuongorora.

Kugadzirira kwe

• Mitiro weMRI haafaniri kuitwa mumhepo yakakwana.
• Pamberi penzira yekuongororwa, murwere anofanira kubvisa zvinhu zvose zvesimbi (maziso, zvishongo, shangu dzemvere, mazino anobviswa).

Muhutano hwose, murwere anomanikidzwa kureva nhema sezvisingabviri, sezvo mufananidzo unoumbwa panguva yekudzidza; Uye zvakanyatsojeka kuti zvichava, zvakanyatsojeka uye zvigadziri zvichave kuongororwa. Panyaya iyi, mumamiriro ezvinhu apo pane chido chekutungamira kuongorora kwemwana muduku, pamwe chete naye mune nyanzvi dzema tomograph vanomanikidzwa kuisa uye amai.

Migumisiro yeongororo

Mufananidzo weMRI uri mifananidzo yezvifananidzo zvinomiririra mifananidzo yakajeka yezvomukati.

Chigumisiro chebhuku rekuongorora rinowanzogadzirira, mumaawa mashomanana mushure mekuongorora chirwere.

Murwere anogamuchira mharidzo yeMRI yakabudiswa iyo inoratidza mifananidzo yakakosha, mifananidzo, uyewo fomu ine kuguma kweyanyanzvi.

Kuti zvive nyore, muzviitiko zvakawanda, diski nezvose, pasina, mifananidzo yakawanikwa panguva yekugadzirisa inopiwawo kumurwere maoko. Iyi nuance inonyanya kukosha mumatambudziko iwayo kana mune remangwana murwere achange achitsvaga kujekesa dhesi rakagadziriswa kuongororwa kune dzimwe nyanzvi.
