Magnetic resonance venography (MRV) chiratidzo chekufungidzira chinoshandiswa kufungidzira maronda emuviri. Mitsetse ndiyo mishonga yeropa inounza ropa kubva munhengo dzomuviri wako kudzokera kumoyo wako nemapapu, saka ropa rinogona kuzadzikiswa ne oksijeni nemuviri.
Iyo Magnetic Resonance Venography Inoita Sei
Izvo hazvingakushamisi kuti MRV inoshandiswa uchishandisa mishonga imwechete yezvokurapa iyo inoshandiswa magnetic resonance imaging (MRI), iyo imashini huru inoshandisa nzira yakanakisisa uye inonakidza kugadzira mufananidzo unomirira zviri kuitika mukati me muviri).
Kunyanya kunyanya, mishoni yeMRI inoshandisa magetsi anoverengeka e "kuverenga" ruzivo, iyo inotumirwa kune kombiyuta ine software yakagadzirwa, yakanyatsogadziridzwa iyo inogona kududzira ruzivo rwakabva kune magnetic equipment.
Iyi ruzivo inoshandiswa kudzokorora chimiro chemuviri, icho chengetani yako yekutarisira hutano inogona kutarisa sezvavanoongorora dambudziko rako rezvehutano.
Mushoni weMRI unogona kugadziriswa kuoneka mifananidzo yezvikamu zvakasiyana zvemuviri, kusanganisira maumbirwo, nzvimbo dzakasimba, uye ropa kana mutezo yeropa. Dzimwe nguva mRI inoshandiswa kutarisa matumire, kukuvadzwa kunorwadza, uye zvirwere zvakadai sitiroko.
Nekucherechedza mitsipa yeropa, zvinokosha kuti usapesane Magnetic Resonance Angiography (MRA) ine MRV. MRA inoshandiswa kutarisa mishonga (chirwere cheropa chinounza oksijeni-yakawanda ropa kune nhengo dzomuviri) apo MRV inotarisa mutsvo.
Chinangwa cheMagnetic Resonance Venography
MRV inoshandiswa kutarisa kubuda kweropa mukati memawere uye inogona kuona kuvhara ropa kana zvimwe zvisiri izvo.
Zvizhinji zvehutachiona hwehutachiona hweropa, zvakadai sitiroko uye kushaya mwoyo, zvinokonzerwa nezvinetso nemishonga, kwete nematambudziko ane mitsetse.
Kazhinji, zvirwere zvemitsipa hazvisi zvishoma kudarika zvirwere zveyeriyo. Uyezve, kakawanda kupfuura kwete, zvirwere zvinosanganisira mitsetse dzinowanzove dzisinganyanyi kuoma kupfuura mamiriro ezvinhu anokonzerwa nechirwere chinopisa.
Ichi ndicho chikonzero chinowanzovanzwa pamusoro peMRI (iyo inogadzira mufananidzo wechirongwa pachayo, kwete mishonga yeropa) kana MRA (iyo inonyanya kugadzirisa kugadzira mufananidzo wehateri) pane kuti inzwe nezveMRV.
Mufananidzo mukuru pano ndewokuti kana iwe uchida kuva neMVV, zvichida kuti chiremba wako ari kukuongororesa dambudziko rehutano husinganzwisisiki rinogona kutora nguva kuti uongorore. Zvimwe zvezvinetso izvi zvinosanganisira zvipfeko zvemuviri zvinokanganisa kana dambudziko rekuyerera kweropa muuropi, kukura kwemafuro asina kunaka mumucheche muduku, uye / kana ropa rinopinza mitsemara, panzvimbo pemishonga.
Chimwe chiitiko chaiyo chinoratidzwa neRVV chinonzi chirwere chinonzi cerebral venous thrombosis, iyo inonzi blood clot mumaketani europi. Kunyange zvazvo kurohwa uye zvirwere zveuropi zvisinganzwisisike kuvasikana vechidiki vane makore ekurera, kune ngozi shoma panguva yekuzvitakura.
Mukuwedzera, dzimwe nguva, urongwa hweuropi hwomwana ari kusimukira kana mwana mucheche muduku haanganzwisisike sezvakatarisirwa, uye uropi MRV inogona kupa ruzivo kana ropa risiri kana kusagadzikana kwechimiro chemitsipa kungave chinhu chinokonzera. Pakupedzisira, mamiriro ezvinhu akadai sokusavhiringidzika kwepenha yepamusoro kana kushandiswa kwemazuva ano hydrocephalus (NPH) inogona kukonzera zviratidzo zvehutano, izvo zvinogona kuongororwa neRMV.
Contraindications for Kuita MRV
Mushoni weMRI unoshandisa magnet, saka iwe haugoni kuva neMVV (kana MRI kana MRA) kana iwe une chigadzirwa chesimbi chakaiswa mumuviri wako. Simba remaginiti ane simba rinoshandiswa mumushini weMRI rinogona kukonzera zvinetso zvakakomba, zvakadai sekuparadzanisa magnet kana kukuvara. Saizvozvowo, kana uine pacemaker, maginiti anogona kuita kuti pacemaker isakanganise, pamwe nemigumisiro yakaipa.
Shoko Rinobva
MRV haisi chirwere chakajairika chekuongorora. Kana iwe uri kuongororwa nokuda kwehutano hwakakosha, kana uine dambudziko reutano rinotora nguva kuti uongorore, unogona kunge uchitya pane zvaunotarisira.
Sezvaunenge uchifamba nenzira iyi, iva nechokwadi chokuti uwane zvakanyanya kubva pane zvehutano hwako nekubvunza mibvunzo uye kutaurirana neboka rako rezvehutano.
