MRI: Izimo ukuba le nkqubo

MRI - yinto indlela ephumelelayo yalula diagnostic evumela ukuba siqwalasele ngokweenkcukacha utshintsho zophendlo lwezifo kunye nesakhiwo izicwili ezithambileyo, amathambo, nemisipha umzimba kunye nezihlunu. Isiphumo kwiimeko ezininzi ilungele neyure emva kwesifundo, nto leyo eyenza kube lula ukuba liqhubeke ukhetho uhlolo kunye nonyango.

Kodwa ke, ngelishwa, asingabo bonke abantu MRI ungenziwa. Izimo kunye neentsilelo kwesi sifundo ubukhulu becala enxulumene ubukho metal emzimbeni kunye nezifo ezithile. ubunzima Body of ezingaphezu kwe-120 kg nako kube umqobo yale nkqubo, nangona kukho ezinye yabavavanyi ezivumela isiguli ukuba unesifo ezinobunzima 180 kg.

Izimo Absolute kuzo zonke iindidi MRI

Kukho iimeko awahambelani MRI. Izimo eli qela ecaleni ngokupheleleyo ithuba ukwenza le nkqubo diagnostic. Loo uphando awukwazi kuthwalwa kubantu abanezincedisi-ntliziyo intliziyo emiselwe kuba lo mhlaba otsalayo kukhokelela sibangelwa kule fowuni. Ngenxa ezimashakeleyo chip isingqi intliziyo kuphuma, yaye impilo yabantu aya kuba sengozini enkulu (de ukufa).

MRI awukwazi ukwenziwa kwabo izigulane kuba nomzimba elisekwe izinto enziweyo zemathiriyeli magnetizable, ngokuba babe shushu kakhulu kwaye ukugqabhuza ngexesha lokusebenza. Ukuba umntu uthe wamvambo emzimbeni, eyasetyenziswa ukupeyinta ngathi sisinyithi - oko kwakhona esalelweyo ukwenza le nkqubo diagnostic.

Izimo isihlobo ukuba MRI

Kukho eziliqela uthi apho isigulana akusoloko kusenzeka ukwenza MRI. Izimo eli qela ungumzalwana, ngoko uyakwazi ukudlula uphando phantsi kweemeko ezithile umntu. Ezi ziquka:

• bephelelwa umoya;
• nokukhulelwa;
• senhliziyo ezingapheliyo;
• isifo sengqondo;
• ukungakwazi ukuba elide kwindawo encinane ezithandwa, kungekhona ukuhamba ngexesha elifanayo.

Metal-yodongwe izithsaba, kwiimeko ezininzi, ezenziwe ngezinto ezinjalo, izinto ezo ezingafanelekileyo magnetized, ngoko ubukho babo emzimbeni asiyonto isalelo for MRI. Kunjalo kusebenza kwisixhobo kunye titanium koko iye intra-zesibeleko nawuphi na indawo. Contraindication malunga isigulo sengqondo nazo zingananzwa ukuba isigulane iya isifundo phantsi kwempembelelo nadlamkisayo kunye kweliso gqirha.

MRI ne ukuchasanisa: Izimo ukuba le nkqubo

Ukuze kuphuculwe amacandelo ngamnye imifanekiso wambi lwenziwa kunye MRI umehluko esiphakathi. Olu phando ngempumelelo ukuba umahluko kwesifo yamathumba uze ufumanise yamathumba zobukhulu ezincinane. Ukongeza Izimo standard MRI ne nshita singàphunyezwa kwiimeko ezinjalo kunye nezifo:

• i uxabane ukuba ichiza ukuphucula umfanekiso;
• Ukukhulelwa kunye lokwaphusa (kuba isifundo koko - lo contraindication ingundoqo);
• ukungasebenzi kakhulu ezingapheliyo le izintso;
• kutshanje babulawa isibindi abohlukeneyo.

Izithintelo ngethuba lokukhulelwa nokuncancisa

Ngexesha MRI umzimba womntu ufumana akukho umthwalo iphiramidi (njengoko, umzekelo, ii-x-reyi okanye CT scan), kodwa basengozini isenzo kwentsimi enamandla ngemagnethi. Ukongeza, izigulane ezininzi elapho kwindawo encinci ngolo sikhatshwa ubuhlungu nasengqondweni. Ngenxa yokuba abafazi abakhulelweyo, musa ukuveza umzimba wakho ntshikilelo, esi sifundo ngokucacileyo akukhuthazwa kwithuba leenyanga ezintathu 1st, xa onke amalungu olungekazalwa akhiwa kuphela.

Sicatshulwa MRI kwithuba leenyanga ezintathu we2 3rd ziimeko engqongqo kunokwenzeka kuphela. Esi sigqibo senziwe yi igqirha khona, zokuxilonga uhlaziya izibonelelo kunye neengozi. Abafazi kwilizwe nabongi oomama kufuneka abasayi kwenziwa a MRI umahluko. Izimo kule ngenxa yokuba ichiza ukuze ibe nefuthe elibi kakhulu kuphuhliso pre-natal womntwana, okanye ngenisa umzimba usana ngethuba lokuncancisa.

MRI yomqolo: Izimo zokufunda

Ukuxilonga herniation, isifo idiskhi sisiba mandundu kunye nezinye utshintsho sisiba mandundu kufuneka silujongisise kwalapho. Ukwahlula ezi States ukusuka sciatica kunye sciatica, izigulane zidla emiselwe i-MRI ye empontshwa. Izimo yale nkqubo ababangela efanayo njengoko izithintelo ngokubanzi kuzo zonke iintlobo zophando. Kodwa kukho ezinye iingongoma ezithile zinxulunyaniswa kwindawo lizwe survey.

Akwenzeki ukuba baqhube MRI emva kwiimeko ezinjalo:

• isigulane wafumana etsolo spinal kukwenzakala Intambo kufuneka ungenelelo ngotyando ngoko nangoko (MRI lwenziwa malunga 10-15 imizuzu, kwaye ngamanye amaxesha oku kulibaziseka kunokuba ezisongela ubomi);
• isigulane akanakuxoka cwaka emqolo ngenxa intlungu kakhulu ukuba akukho qabu yi analgesics.

MRI yomqolo, kwakunye naziphi na ezinye intsimi, akunakwenzeka ukuba enze ukuba umzimba womntu ntshunxekile iingceba izinto ezingaziwayo.
