Magnetic resonance imaging: chii icho, chii chaicho uye kuti chinoitwa sei

• Mhando dzeMRI

Magnetic resonance imaging (MRI), inozivikanwawo seyenyukireya magnetic resonance imaging (NMR), bvunzo yemufananidzo inokwanisa kuratidza zvemukati mitezo yenhengo nedudziro, zvichikosha kuongorora matambudziko akasiyana ehutano, senge aneurysms, tumors, shanduko mu majoini kana kumwe kukuvara kunhengo dzemukati.

Kuita bvunzo, muchina muhombe unoshandiswa, uyo unogadzira yakakwira-tsananguro mifananidzo yenhengo dzemukati kuburikidza nekushandisa kwemagineti munda, iyo inokonzeresa mamorekuru emuviri kushushikana, kutorwa nechinhu uye kuendeswa kune komputa. Bvunzo dzinotora maminetsi gumi nemashanu kusvika makumi matatu uye, kazhinji, hapana gadziriro inodiwa, kunyangwe zvingave zvichidikanwa kushandisa musiyano, mune dzimwe nguva, kuburikidza nejekiseni remushonga kuburikidza netsinga.

Chii ichochi

Magnetic resonance imaging inoratidzwa mune inotevera kesi:

• Ziva chirwere chetsinga, senge Alzheimer's, bundu reuropi, multiple sclerosis kana sitiroko, semuenzaniso;
• Cherekedza kuzvimba kana hutachiona muuropi, tsinga kana majoini;
• Tsvaga kukuvara kwemasukloskeletal, senge tendonitis, kukuvara kwegumbo, cysts, senge Tarlov's cyst kana herniated disc, semuenzaniso;
• Ziva masasa kana mamota munhengo dzemuviri;
• Cherekedza shanduko mumidziyo yeropa, senge aneurysms kana kugwamba.

Izvo zvinodikanwa kuti utore matanho ekuzvidzivirira usati waita bvunzo iyi, sezvo pangasave nechero rudzi rwechinhu chesimbi padhuze nemagineti yechigadzirwa, senge homwe dzemvere, magirazi kana ruzivo rwehembe, nekudaro uchidzivirira tsaona. Nechikonzero chimwe chete ichi, bvunzo iyi inopesana kune vanhu vane chero mhando yekunyepedzera, pacemaker kana simbi pini yakaiswa mumuviri.

Pamusoro pehunhu hwakanaka hwemifananidzo yakaumbwa nemagineti resonance imaging, imwe mukana ndeye kusashandiswa kwemayoni eionizing kuwana mhedzisiro, zvakasiyana nekomputa tomography. Nzwisisa kuti ndeyei uye kana CT scan ichidikanwa.

Zvinoitwa sei

Magnetic resonance imaging inowanzo gara pakati pemaminetsi gumi nemashanu kusvika makumi matatu, uye inogona kupera kusvika maawa maviri zvichienderana nenzvimbo ichaongororwa. Kune izvi, zvakakosha kuti urambe uri mukati mechigadzirwa chinoburitsa simba remagineti, uye hazvikuvadze, zvisinei, zvakakosha kuti usatama panguva ino, nekuti chero kufamba kunogona kuchinja kunaka kwebvunzo.

Muvanhu vasingagone kumira vakamira, sevana, vanhu vane claustrophobia, dementia kana schizophrenia, semuenzaniso, zvingave zvakafanira kuita bvunzo ne sedation yekukonzera kurara, zvikasadaro bvunzo dzinogona kunge dzisingashande.

Uye zvakare, mune dzimwe nguva, zvinogona kuve zvakakosha kuisa musiyano mutsinga yemurwere, senge Gallium, sezvo iri nzira yekukonzeresa kududzirwa kukuru kwemifananidzo, kunyanya kufungidzira nhengo kana mitsipa yeropa.

Mhando dzeMRI

Mhando dzeMMRI dzinoenderana nesaiti yakakanganiswa, iyo yakajairika inosanganisira:

• Magnetic resonance imaging yemapapiro, mudumbu kana chipfuva: inoshanda kuongorora mamota kana mashoma munhengo dzakadai sechibereko, ura, mazai, prostate, dundira, rwatata, kana moyo, semuenzaniso;
• Kufananidza kweMagnetic resonance dehenya: inobatsira kuongorora kusagadzikana kwehuropi, kubuda ropa mukati, cerebral thrombosis, tumota dzehuropi uye zvimwe shanduko kana hutachiona muuropi kana mumidziyo yayo;
• Mutsara MRI: inobatsira kuongorora matambudziko musana uye musana, senge mamota, calcification, hernias kana mapfupa zvidimbu, mushure mekupunzika - Ona maitiro ekuziva arthrosis mumuzongoza, semuenzaniso;
• MRI yezvibatanidzwa, senge pabendekete, mabvi kana ankle: inoshanda kuongorora zvinyoro zvinyoro mukati memubatanidzwa, senge bursa, tendon uye ligaments.

Magnetic resonance imaging ndeye, nekudaro, muyedzo wakanakisa wekutarisa zvinyoro-nyoro zvemuviri, zvisinei, hazviwanzo kuratidzwa kutarisa maronda munzvimbo dzakaomarara, senge mapfupa, kuve, mune idzi kesi, bvunzo dzakadai seX-ray kana computed tomography yakanyanya kuratidzwa., semuenzaniso.
