MRI

Imagineti resonance imaging (MRI) scan muyedzo wekufungidzira unoshandisa magineti ane simba nemafungu eredhiyo kugadzira mifananidzo yemuviri. Izvo hazvishandise ionizing radiation (x-rays).

Mifananidzo imwe yeMRI inonzi zvidimbu. Mifananidzo yacho inogona kuchengetwa pakombuta kana kuprindwa pafirimu. Imwe bvunzo inogona kuburitsa zviuru zvemifananidzo.

Mhando dzakasiyana dzeMRI dzinosanganisira:

• Abdominal MRI
• Cervical MRI
• Chest MRI
• Cranial MRI
• Mwoyo MRI
• Lumbar MRI
• Pelvic MRI
• MRA (MR Angiography)
• MRV (MR Venography)

Iwe unogona kukumbirwa kupfeka jasi repachipatara kana zvipfeko zvisina zipi kana mabhureki (senge juzi neteki). Dzimwe mhando dzesimbi dzinogona kukonzeresa mifananidzo.

Iwe unorara patafura yakamanikana, iyo inotsvedza kupinda mune yakakura tunnel-yakaita scanner.

Mimwe bvunzo inoda chaiyo dhayi (musiyano). Kazhinji yenguva, dhayi rinopihwa kuburikidza netsinga (IV) iri muruoko rwako kana ruoko rwemberi bvunzo usati waitwa. Iyo dhayi inobatsira iyo radiologist kuona dzimwe nzvimbo zvakajeka.

Midziyo midiki, inonzi makoiri, inogona kuiswa yakatenderedza musoro, ruoko, kana gumbo, kana kutenderedza dzimwe nzvimbo dzinodzidzwa. Izvi zvinobatsira kutumira uye kugamuchira masaisai eredhiyo, uye nekuvandudza mhando yemifananidzo.

Munguva yeMRI, munhu anoshandisa muchina anozokutarisa kubva kune imwe kamuri. Muedzo unotora maminetsi makumi matatu kusvika makumi matanhatu, asi zvinogona kutora nguva yakareba.

Iwe unogona kubvunzwa kuti usadye kana kunwa chero chinhu kwemaawa mana kusvika matanhatu usati scan.

Udza mupi wako wezvehutano kana iwe uchitya nzvimbo dzepedyo (une claustrophobia). Iwe unogona kupihwa mushonga wekukubatsira kuti unzwe kurara uye kusanyanya kunetseka, kana wako mupi anogona kupa rairo rakavhurika reMRI, umo muchina wacho usiri padhuze nemuviri.

Usati waedzwa, udza mupi wako kana iwe uine:

• Chakagadzirwa mwoyo mavharuvhu
• Brain aneurysm clip
• Mwoyo defibrillator kana pacemaker
• Nzeve yemukati (cochlear) implants
• Chirwere cheitsvo kana dialysis (unogona kusakwanisa kugamuchira musiyano)
• Ichangobva kuiswa majoini ekugadzira
• Vascular stents
• Inoshanda nesheet simbi munguva yakapfuura (ungangoda bvunzo kuti utarise zvidimbu zvesimbi mumaziso ako)

Nekuti iyo MRI ine magineti akasimba, zvinhu zvesimbi hazvitenderwe kupinda mukamuri ine MRI scanner:

• Zvinhu zvakaita seishongo, mawachi, makadhi echikwereti, uye zvekunzwa zvinogona kukuvara.
• Peni, homwe, uye magirazi emaziso anogona kubhururuka nepamusoro pemba.
• Pini, pini dzebvudzi, zipi yesimbi, uye zvimwe zvinhu zvesimbi zvinogona kukanganisa mifananidzo.
• Basa rinobvisika remazino rinofanira kuburitswa pasati paitwa scan.

Kuongorora kweMRI kunokonzera kurwadziwa. Kana uchinetseka kurara wakadzikama kana kutya zvakanyanya, unogona kupihwa mushonga wekukuzorodza. Kufamba kwakanyanya kunogona kukanganisa mifananidzo yeMRI uye kukonzera zvikanganiso.

Tafura yacho inogona kunge yakaoma kana kutonhora, asi unogona kukumbira gumbeze kana mutsago. Muchina unoburitsa ruzha rukuru uye ruzha kana ichivhurwa. Iwe unogona kupfeka nzeve plugs kubatsira kudzikisa ruzha.

Intercom iri mumba inokutendera kuti utaure nemumwe munhu chero nguva. Mamwe maMRI ane materevhizheni uye akasarudzika mahedhifoni aunogona kushandisa kubatsira nguva kupfuura.

Iko hakuna nguva yekudzoreredza, kunze kwekunge iwe ukapihwa mushonga wekuzorora. Mushure meMRI scan, unogona kutangazve chako chakajairwa chikafu, chiitiko, uye mishonga.

Kuva neMRI kunogona kubatsira kazhinji:

• Ongorora hutachiona
• Tungamira chiremba kunzvimbo chaiyo panguva yebhiopsy
• Ziva masasi nemamota, kusanganisira cancer
• Dzidza tsinga dzeropa

Mifananidzo yeMRI inotorwa mushure medhayi (musiyano) yakaunzwa mumuviri wako inogona kupa rumwe ruzivo nezve iyo tsinga dzeropa.

Magnetic resonance angiogram (MRA) chimiro chemagineti resonance imaging inogadzira mifananidzo-mitatu yemitsipa yeropa.

Mhedzisiro mhedzisiro zvinoreva kuti nzvimbo yemuviri iri kudzidzwa inotaridzika kunge yakajairwa.

Mhedzisiro inoenderana nechikamu chemuviri chiri kuongororwa uye nemhando yedambudziko. Mhando dzakasiyana dzemasuru dzinodzosera kumashure akasiyana maMRI masaini. Semuenzaniso, zvinyama zvine hutano zvinotumira kumashure chiratidzo chakatosiyana pane chegomarara. Bvunza mupiki wako chero mibvunzo uye zvinonetsa.

MRI haishandisi ionizing radiation. Hapana mhedzisiro kubva kumagineti minda uye masaisai eredhiyo akataurwa.

Rudzi rwakanyanya kujairika rwekusiyanisa (dhayi) rinoshandiswa gadolinium. Chinhu ichi chinofungidzirwa kuti chinowanzo chengetedzeka kuvanhu vazhinji. Gadolinium inochengetwa muuropi uye dzimwe nhengo (kusanganisira ganda mune vanhu vane chirwere cheitsvo) mushure mekushandisa. Mune zvisingawanzoitika zviitiko, nhengo uye ganda kukuvara kwakaitika kune varwere vane preexisting itsvo kutadza Taurira wako mupi pamberi pekuyedzwa kana uine itsvo matambudziko.

Iwo akasimba magineti maseru akagadzirwa panguva yeMRI anogona kukonzera kugadzikana kwemoyo uye zvimwe zvinodyara kuti zvirege kushanda zvakare. Iwo magineti anogona zvakare kukonzera chidimbu chesimbi mukati memuviri wako kufamba kana kuchinja.
