MRI uropi - mukana kutarisa waibva mukati

Magnetic resonance kuri (kana MRI) uropi, marangwanda uye dzimwe nhengo sezvo nzira kutsvakurudza repfupa rinenge inhaurwa kuenderera X-ray kuongororwa uye kuri vachishandisa kombiyuta. Kwerinopfuura zana apfuura, mashoko ezvokurapa kwakaratidza kuti zvinokwanisika kutarisa mukati muviri, kana vaigona kushandisa zvivako zviri X-ray danda mumuviri. Chokutanga pfuma: panguva danda wavelength rakapfupika kupfuura chiedza wave. Chechipiri, kuti X-ray danda anokwanisa munhumbi tishu. gobvu nyama dzawo Sechipanji, fungisisa nyoro. In mufananidzo kunonyatsooneka kuoneka magumo ndiyo mapfupa, mazino, chipfuva.

Computed tomography yakazokudziridzwa pashure pakusuma kupinda okurapa zvishandiswa kombiyuta. kudzidza Izvi chaizvo zvakafanana X-ray. chete ari dzaidzidziswa zvakasiyana siyana sensors kuti kutungamira maekisirei mune nzvimbo shoma panguva imwecheteyo, sokunge kutema chipfuro nhengo kupinda zvidimbu zvakawanda. Nzira iyi kunotibatsira kuona womukati nemamiriro mapfupa ari chikamu uye zvakadzama. zvifananidzo zvose zviri chakasvitswa kuti pakombiyuta, apo vanogona kuva nokungwarira uye leisurely mundotarisisa chiremba.

Zvisinei, sezvo x-mwaranzi uye CT Scans kufumura munhu nemwaranzi, uye yakawanda chete. Somugumisiro, anogona kutsamwisa kunotouraya mumuviri uye kutungamirira kukudziri- nemasero kenza. nekuipira kwakadaro kubva maekisirei kurudzira vanachiremba pamwe chete masayendisiti kuti vatsvake nzira ngozi kutsvakurudza dzemuviri. Saka, muna kunyatsodzidza mitemo mumuviri uye vave michina mitsva zvakatungamirira kuti chidzoke muna 1973 imwe nzira itsva.

Hwaro kare tirege X-ray nemwaranzi, uye zvivako zviri rinobva minda uye redhiyo mafungu. Chifananidzo chidzitiro panguva MRI uropi, uyewo mamwe mapfupa rinenge vakawana muna mugumisiro musimboti hydrogen atomu inova chikamu pfupa kuferefetwa iri pachena kuti remagetsi nemwaranzi dzakasiyana maitikiro. Akayera chitsama simba kuti anoratidza kubva chinoumba sezvo ari kufara mamiriro, uye nechinguvana kuzvivaraidza. ruzivo zvose izvi zvokudya kuva kombiyuta, uchishandisa kwemasvomhu algorithms vari kupatsanurwa - uye chinhu chinovhara anoratidza mufananidzo yakarurama kwazvo anoverengeka akaturikidzana pfupa, kana mumwe muviri.

chirwere ichi zvinobvumira vanachiremba kuongorora zvose uye kuziva chirwere zvomukati, izvo zvakasiyana haagoni kuongororwa. Sezvo zvakaoma kwazvo kuti kutarira mukati dehenya, pane nzira yechokwadi imwe chete kuongorora nyoro zvinyama mukati nayo - ndiyo MRI wouropi. Kupi uye kuri kuenda sei?

Chii MRI uropi? Iri nyore chaizvo nzira murwere. Simply kuenda scanner - rakamanikana scanner pamwe sensors. Kunyepa vachine gumi kusvika matatu maminitsi. Nokuti chinangwa ichi, ivo chinogona kubatanidzwa maoko, makumbo, muchipfuva, uye musoro chaiwo mabhandi kushomeka mufambo muviri. Kumboda scanners chaizvo yakatetepa, zvinogona kukonzera kusanzwa. Dzimwe nguva, vamwe varwere unosanganisira kurwisa mokutya pachidzidzo. Nokuda kwechikonzero ichi, isu akakurukura rakazaruka MRI scanner.

Zvinonzi kuzivikanwa kuti simbi uye zvinhu-akaafukidza nendarama zviri chaizvo kunzwisisa remagineti, saka panguva vakaongorora zvinhu zvakadai kubva murwere hakufaniri kuva pamusoro muviri, uye mumba zvakare. All chishongo, mabhatani, uye kunyange kuita-up vanofanira kubviswa pamberi bvunzo. Nokuti chete zvikonzero, MRI uropi kana mumwe nhengo haagoni anoitwa varwere vaya chakagadzirwa nemakumbo, pacemakers kana mumwe simbi anodyara.

Mumakore achangopfuura, izvozvo rave kushandiswa uropi MRI pamwe musiyano. Musimboti nzira iri kuti murwere unotora pamberi chidzidzo kusiyana pomutumwa. Rinopa mukana kuchengeta ezvinhu akasiyana-siyana nhumbi uropi uye kufamba kweropa chero ezvinhu. Vamwe varwere vanogona kuva sema maitiro kune fuma. Uye kuti, zvichida, chete kukuvadza inogona kuunza munhu mhando nechirwere. Kazhinji, MRI ari chaizvo Detective zvirwere, akavanda seri mafupa.
