Mwoyo MRI

Mwoyo magnetic resonance imaging inzira yekufungidzira iyo inoshandisa magineti ane simba uye masaisai eredhiyo kugadzira mifananidzo yemoyo. Izvo hazvishandise radiation (x-rays).

Imwe chete magnetic resonance imaging (MRI) mifananidzo inonzi zvidimbu. Mifananidzo yacho inogona kuchengetwa pakombuta kana kuprindwa pafirimu. Imwe bvunzo inogadzira akawanda kana dzimwe nguva mazana emifananidzo.

Muedzo unogona kuitwa sechikamu cheMRI yechifuva.

Unogona kubvunzwa kupfeka jasi rechipatara kana zvipfeko zvisina zvekusunga simbi (senge juzi neteki). Dzimwe mhando dzesimbi dzinogona kukonzeresa mifananidzo kana kukwezva kune magineti ane simba.

Iwe unorara patafura yakamanikana, iyo inotsvedza kupinda muhombe-yakaita sepombi.

Mimwe bvunzo inoda chaiyo dhayi (musiyano). Iyo dhayi inowanzo kupihwa usati waedzwa kuburikidza netsinga (IV) iri muruoko rwako kana ruoko. Iyo dhayi inobatsira iyo radiologist kuona dzimwe nzvimbo zvakajeka. Izvi zvakasiyana nedhayi inoshandiswa paCT scan.

Munguva yeMRI, munhu anoshandisa muchina anozokutarisa kubva kune imwe kamuri. Muedzo unowanzo kutora 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). Unogona kupihwa mushonga wekukubatsira kuti unzwe kurara uye usanyanya kunetseka, kana mupi wako anogona kupa zano "rakavhurika" MRI, umo muchina wacho usiri padhuze nemuviri.

Usati waedzwa, udza mupi wako kana iwe uine:

• Brain aneurysm clip
• Dzimwe mhando dzemagetsi ekuisira emoyo
• Mwoyo defibrillator kana pacemaker
• Nzeve yemukati (cochlear) implants
• Chirwere cheitsvo kana dialysis (unogona kusakwanisa kugamuchira musiyano)
• Ichangobva kuiswa majoini ekugadzira
• Dzimwe mhando dzevascular 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:

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

Bvunzo yemoyo yeMRI inokonzeresa kurwadziwa. Vamwe vanhu vanogona kushushikana kana vari mukati ma scanner. Kana iwe uchinge uchinetseka kurara wakadzikama kana uine shungu kwazvo, unogona kupihwa mushonga wekuti uzorore. Kufamba kwakanyanya kunogona kukanganisa mifananidzo yeMRI uye kukonzera zvikanganiso.

Tafura yacho inogona kunge yakaoma kana kutonhora, asi iwe unogona kukumbira gumbeze kana mutsago. Muchina unoburitsa ruzha rukuru uye ruzha kana ichivhurwa. Unogona kupihwa nzeve nzeve kuti ubatsire kudzikamisa ruzha.

Iyo intercom mune iyo scanner inokutendera iwe kuti utaure kune munhu ari kushandisa bvunzo chero nguva. Mamwe maMRI scanner ane materevhizheni uye akakosha mahedhifoni kubatsira kupfuudza nguva.

Iko hakuna nguva yekudzosa, kunze kwekunge sedation yaidikanwa. (Iwe uchazoda mumwe munhu kuti akutakure kuenda kumba kana sedation yakapihwa.) Mushure meMRI scan, unogona kutangazve kudya kwako kwakajairika, chiitiko, uye mishonga, kunze kwekunge iye anokupa akakuudza neimwe nzira.

MRI inopa yakajeka mifananidzo yemoyo nemidziyo yeropa kubva kune akawanda maonero. Kazhinji, inoshandiswa kana rumwe ruzivo ruchidikanwa mushure mekunge iwe uine echocardiogram kana moyo CT scan. MRI yakanyatsojeka kupfuura CT scan kana imwe bvunzo yemamwe mamiriro, asi isina kukwana kune vamwe.

Mwoyo MRI inogona kushandiswa kuongorora kana kuongorora:

• Kukuvara kwemhasuru yemwoyo mushure mekurwadziwa kwemoyo
• Kuremara kwekuzvarwa kwemoyo
• Mamota emwoyo uye kukura
• Kushaya simba kana mamwe matambudziko ane mhasuru yemoyo
• Zviratidzo zvekutadza kwemoyo

Mhedzisiro isina kujairika inogona kunge iri nekuda kwezvinhu zvakawanda, zvinosanganisira:

• Matambudziko emagetsi emoyo
• Fluid musaga-senge yakafukidza yakatenderedza moyo (pericardial effusion)
• Bundu remitsipa yeropa kana yakatenderedza moyo
• Atrial myxoma kana kumwe kukura kana bundu mumoyo
• Congenital chirwere chemoyo (dambudziko remwoyo iro raunozvarwa naro)
• Kukuvadza kana kufa kune yemhasuru yemoyo, inoonekwa mushure mekurwadziwa kwemoyo
• Kuzvimba kwemhasuru yemoyo
• Kupinda mukati memhasuru yemwoyo nezvinhu zvisina kujairika
• Kushaya simba kwemhasuru yemwoyo, iyo inogona kukonzerwa nesarcoidosis kana amyloidosis

Iko hakuna radiation inobatanidzwa muMRI. Iwo magineti minda uye masaisai eredhiyo anoshandiswa panguva yekutarisa haana kuratidzwa kukonzera chero akakosha mhedzisiro.

Allergic reaction kune iyo dhayi yakashandiswa panguva yebvunzo hazviwanzo. Rudzi rwakanyanya kujairika rwekusiyanisa (dhayi) rinoshandiswa gadolinium. Zvakachengeteka chaizvo. Iye munhu arikushandisa muchina anoongorora yako yekurova kwemoyo uye kufema sekudikanwa Kazhinji matambudziko anogona kuitika kune vanhu vane dambudziko rakakomba reitsvo.

Vanhu vakakuvadzwa mumichina yeMRI pavasina kubvisa zvinhu zvesimbi kubva munhembe dzavo kana pakasara zvinhu zvesimbi mumba nevamwe.

MRI inowanzo kusakurudzirwa nekuda kwekukuvara kunorwadza. Traction uye yehupenyu-yekutsigira michina haigone zvakachengeteka kupinda munzvimbo ye scanner.

MRIs inogona kudhura, kutora nguva yakareba kuti uite, uye inonzwisisa kufamba.
