Kutheni i-MRI ingeyonto yesiqhelo yoVavanyo oluNgxamisekileyo?

Kwisebe lokujonga imifanekiso yezonyango, kudla ngokubakho ezinye izigulana “ezinoluhlu olungxamisekileyo” lweMRI (MR) ukuze zenze uhlolisiso, zize zithi kufuneka zilwenze ngokukhawuleza. Kule meko kaxakeka, ugqirha obonisa imifanekiso uhlala esithi, “Nceda wenze idinga kuqala”. Siyintoni isizathu?

Okokuqala, makhe sijonge i-contraindications:

Ekuqaleni,Contraindications ngokupheleleyo

1. Izigulane ezine-cardiac pacemakers, i-neurostimulators, i-artificial metal heart valves, njl.;

2. Ngekliphu ye-aneurysm (ngaphandle kwe-paramagnetism, njenge-titanium alloy);

3. Abantu abanemizimba yangaphandle yentsimbi ye-intraocular, ukufakelwa kwendlebe yangaphakathi, iprosthesis yesinyithi, iprostheses yesinyithi, amalungu esinyithi, kunye nemizimba yangaphandle ye-ferromagnetic emzimbeni;

4. Ukukhulelwa kwangethuba kwiinyanga ezintathu zokukhulelwa;

5. Izigulane ezinomkhuhlane ophezulu kakhulu.

Ngoko ke, yintoni isizathu sokuba iMRI ingathwali isinyithi?

Okokuqala, kukho indawo enamandla yamagnetic kwigumbi lomatshini we-MRI, enokubangela ukutshintshwa kwesinyithi kwaye kubangele ukuba izinto zetsimbi zibhabhe kwiziko lezixhobo kwaye zenze umonakalo kwizigulane.

Okwesibini, intsimi ye-MRI RF enamandla inokuvelisa ifuthe lobushushu, ngaloo ndlela ibangela ukufudumeza kwezinto zetsimbi, uvavanyo lwe-MRI, lusondele kakhulu kumhlaba wemagnethi, okanye kumhlaba wemagnethi kunokubangela ukutshisa kwezicubu zengingqi okanye kube sengozini ubomi bezigulana.

Okwesithathu, kuphela intsimi yamagnetic ezinzileyo kunye efanayo inokufumana umfanekiso ocacileyo. Xa kukhangelwa ngezinto zetsimbi, izinto zokwenziwa kwendawo zinokuveliswa kwindawo yesinyithi, echaphazela ukufana kwemagnethi kwaye ayikwazi ukubonisa ngokucacileyo ukuchasana kweempawu zezicubu eziqhelekileyo ezijikelezileyo kunye nezicubu ezingaqhelekanga, ezichaphazela ukuxilongwa kwesifo.

Isibini,Contraindications ezinxulumene

1. Izigulane ezinemizimba yangaphandle yesinyithi (i-metal implants, i-dentures, i-contraceptive rings), iipompo ze-insulin, njl., Kufuneka zihlolwe nguMR, kufuneka ziqaphele okanye zikhangele emva kokususwa;

2. Izigulane ezigula kakhulu ezifuna ukusetyenziswa kweenkqubo zokuxhasa ubomi;

3. Izigulane ezine-epilepsy (i-MRI kufuneka yenziwe phantsi kokulawulwa ngokupheleleyo kweempawu);

4. Kwizigulane ze-claustrophobic, ukuba i-MR Examination iyimfuneko, kufuneka iqhutywe emva kokunika umlinganiselo ofanelekileyo we-sedative;

5. Izigulane ezinobunzima ekusebenzisaneni, njengabantwana, kufuneka zinikwe i-sedatives ezifanelekileyo emva;

6. Abafazi abakhulelweyo kunye neentsana kufuneka bahlolwe ngemvume kagqirha, isigulane kunye nosapho.

Okwesithathu, yintoni ubudlelwane phakathi kwezi taboo kunye nokungenzi imagnethi yenyukliya engxamisekileyo?

Okokuqala, izigulane ezingxamisekileyo zikwimeko enzima kwaye ziya kusebenzisa i-ECG yokubeka iliso, ukubeka iliso kokuphefumula kunye nezinye izixhobo nangaliphi na ixesha, kwaye uninzi lwezi zixhobo azikwazi ukungeniswa kwigumbi le-magnetic resonance, kwaye ukuhlolwa okunyanzeliswayo kunomngcipheko omkhulu ekukhuseleni ukhuseleko lobomi. izigulane.

Okwesibini, xa kuthelekiswa nokuhlolwa kwe-CT, ixesha le-MRI scan lide, uviwo olukhawulezayo lwe-skull luthatha ubuncinane imizuzu eyi-10, ezinye iindawo zexesha loviwo zide. Ngoko ke, kwizigulane ezigula kakhulu ezineempawu zokungazi, i-coma, i-lethargy, okanye ukuphazamiseka, kunzima ukugqiba i-MRI kule meko.

Okwesithathu, i-MRI ingaba yingozi kwizigulane ezingakwazi ukuchaza ngokuchanekileyo utyando lwazo lwangaphambili okanye enye imbali yonyango.

Okwesine, kwizigulana ezingxamisekileyo ezihlangabezana neengozi zemoto, ukuphuka, ukuwa, njl., Ukunciphisa ukuhamba kwezigulane, ngokungabikho kwenkxaso yokuhlola ethembekileyo, oogqirha abanako ukugqiba ukuba isigulane sinokwaphuka, ukuphuka kwangaphakathi kunye nokuphuma kwegazi, kwaye ayinakuqinisekisa ukuba kukho imizimba yesinyithi yangaphandle ebangelwa kukwenzakala. Uvavanyo lwe-CT lufanelekile ngakumbi kwizigulane ezineemeko zokunceda ukusindisa izigulane ngexesha lokuqala.

Ngoko ke, ngenxa yovavanyo oluthile lwe-MRI, izigulane ezingxamisekileyo kwiimeko ezinzima kufuneka zilinde imeko ezinzile kunye novavanyo lwesebe ngaphambi kokuhlolwa kwe-MRI, kwaye kunethemba lokuba uninzi lwezigulane zinokunika ukuqonda okungakumbi.
