Chii MRI: nheyo scanner uye chirwere nezvaanogona

Mukurapa, rinoshandisa vazhinji paku zveBhaibheri, vamwe vari Chokwadi, nokudenga, kuti anogona rokuongorora pathologies zhinji kubva mumapoka kupatsanura akasiyana zvirwere zvevanhu. Ndizvo MRI muchina unobvumira kuona munyama muviri pasina kushandisa nemwaranzi chokupfeka. Zvisinei, kuti ndiye MRI uye sei nemamiriro dhayagiramu ari mudziyo, ayo vanoshanda musimboti, anoziva vashoma vanhu. Asi kusaziva ichi hakutadzisi ruzhinji varwere kuwana chirwere nzira dzakadaro.

Nemamiriro MRI midziyo uye musimboti oparesheni

Midziyo yokuita MRI huru magineti. Muviri womunhu ari mhango kwayo, izvo runochengetedzwa munhu epurasitiki casing. Uyezve, kudzidza ichi hahubvi pazvinhu zvinyama kutanga pathological ezvinhu, nokuti havaiti ionize zvinhu zviri muzasi muviri mamiriro. The simba remagineti mudziyo anoita zvakananga pamusoro protons. nezvimedu izvi zvinomiririra rehydrogen ions kuti vari chikamu mvura - vakawanda fuma mumuviri womunhu.

The mvura tigutsikane iri siyana dzomuviri womunhu ane misiyano ayo. It iduku uwandu pfupa uye connective rinenge nepo tsandanyama uye mafuta kuva yepamusoro yevasungwa emura. Chete unhu uye zvakasiyana uropi uye parenchyma ose zvomukati. Saka, nokuda musiyano mumvura kugutsikana yakawana kuvakwa miganhu pakati dissimilar nyama pamusoro rakapotsa mufananidzo kwakaita pashure mureza kuti kombiyuta.

Zvisinei, kuti ndiye MRI, pahwaro rwomuviri nhungamiro chikwata ichi inoshanda? Izvi mhando Kusiyanisa muviri womunhu mamiriro chaitwa nokuda matambudziko mashandiro mvura mamorekuru. Dzinomirira dipoles ari remagineti iyo kugamuchira mumwe mhando dzidziso. MRI pachake kushanda kutenderera ari kuumba remagineti uye mamiriro nokuda yakarongeka urongwa mvura mamorekuru, uye ipapo pamwe remagineti ndiro akatanga Radio wave unounza Morekuru kune vibrations kuti yakakura nokuda resonance kuitika.

MRI musoro, tsvakurudza uropi

In nechirwere kwezvirwere uye chinopedza maronda uropi MRI zviri kukosha nokuti anobvumira refu mwero mukana kusarudza chaiyo localization kwacho, uwandu kukuvara kana neoplasm kuziva mudziyo umo clot iri. Panyaya iyi, chikuru yokusvika mufambiro kudzidza ichi haisi nzira rokuongorora nokuti hwaro kuri ari abvunza mubvunzo "chii?" Zvino mhinduro yacho. Kwakadaro MRI ane akatorwa pashure pre-pachena chirwere, unogona kuvandudza ruzivo zviri kudzidza, nokuti chiremba yakatotanga akataura kuti achaita zvakananga kutsvaka. Uyezve, pakati chipfuro pathologies kuti anogona kuona pfungwa MRI, bundu chipo, zvinorwadza, zvirwere zvinotapukira. Uyewo, MRI anokwanisa diagnosing kuti matambudziko kuti inomuka panguva kukura zvirwere-dzataurwa pamusoro apa.

Chii MRI of muzongoza

MRI pamusoro musana uye musana - ndiyo nzira paku zvidzidzo, unosanganisira Visualization of anatomical hurongwa huri pamwero. Modern mano anobvumira dzakasiyana-siyana chaivo zvidimbu nomunhu nhengo dzomuviri. Izvi zvinoita kuti tikwanise kuongorora anatomical nemamiriro musana canal, intervertebral maburi munzvimbo dzakasiyana. Kudzidza rinewo ari musana, nekuti ichi rinobvumira MRI kuona nechivako yayo, nokuti inductance simba remagineti ari coils midziyo iri anenge 1.5 Tesla. Kushandisa kuri kunobatsira kuziva pamberi bundu inotungamirwa ari meninges kana zvayo runoenzanirana tishu symptomatology.
