Uyoyika i-MRI scan? Masithethe ngayo ngokulula (iMagnetic Resonance Imaging)

Xa ugqirha wakho ekuxelela ukuba wenze i-MRI scan, usenokuziva usoyika kancinci kwaye unexhala. 'Yintoni le? Ingaba iza kuba buhlungu? Ngaba kufuneka ndingene kumatshini omkhulu?' Usenokuba nemibuzo emininzi ezayo engqondweni yakho. Kodwa ungoyiki. I-MRI luvavanyo olubaluleke kakhulu, olungenabuhlungu olunokunceda ekufumaneni izifo ezininzi. Namhlanje, siza kuthetha ngayo yonke into ngendlela elula kakhulu.

Ngamafutshane, yintoni i-MRI?

I-MRI (Magnetic Resonance Imaging) luvavanyo olungenabuhlungu olusebenzisa imagnethi enamandla, amaza erediyo, kunye nekhompyutha ukwenza imifanekiso ecacileyo yamalungu omzimba kunye namanye amalungu omzimba wakho.

Ngenxa yokuba ayisebenzisi ii-X-ray, oogqirha badla ngokucebisa ii-MRI scans kwabo bafuna ii-scan rhoqo, ingakumbi abo bajonga iimeko ezinxulumene nobuchopho.

Kukho iintlobo ezimbini zemishini ye-MRI - eVulekileyo neValiweyo.

Ukuba ungumntu onokuba ne-claustrophobia, kubalulekile ukuba uqaphele oku.

• I-MRI evulekileyo: Lo matshini unemagnethi ezimbini phezulu nasezantsi. Indawo ekufuneka ulale kuyo ivulekile kumacala omabini, ukuze ungaziva uxinene. Oku kulungile kubantu aboyika iindawo ezixineneyo. Nangona kunjalo, imifanekiso ethathwe ngalo matshini isenokungacaci njengakwezinye iintlobo zoomatshini.
• I-MRI evaliweyo: Olu lolona hlobo luqhelekileyo. Ijongeka njengetyhubhu engqukuva. Uthunyelwa ngaphakathi kule ukuze ihlolwe. Incinci kancinci, ngoko abanye abantu banokuziva bengakhululekanga okanye besoyika xa bengaphakathi. Nangona kunjalo, lo matshini unokuthatha imifanekiso esemgangathweni necacileyo.

Ukuba uyoyika iindawo ezixineneyo, xelela ugqirha wakho kwangaphambili. Ukuba kuyimfuneko, banokukunika amayeza okuthomalalisa ukuze uhlale uzolile.

Yintoni i-MRI scan ene-contrast?

Kwezinye ii-MRI scans, kuya kufuneka ufake ulwelo olukhethekileyo (izinto ezichaseneyo) emthanjeni osengalweni yakho. Olu lwelo lunesinyithi esingaqhelekanga esibizwa ngokuba yi-gadolinium.

Xa olu lwelo lungena emzimbeni, lutshintsha iimpawu zemagnethi zezicubu ezijikelezileyo, nto leyo eyenza imifanekiso icace ngakumbi. Kufana nokujonga ifoto emnyama nomhlophe ngombala, nto leyo eyenza izinto ezithile zibonakale ngokucacileyo.

Ezi contrast fluids zihlala zikhuselekile. Nangona iziphumo ebezingalindelekanga zinokubakho, iimeko ezimandundu azixhaphakanga.

Yintoni umahluko phakathi kwe-MRI kunye ne-CT scan?

Abantu abaninzi bayabhideka ezi scan zimbini. Makhe sijonge eminye yemiba ephambili phakathi kwezi scan zimbini.

Yintoni enokubonwa nge-MRI scan?

I-MRI iyakwazi ukubona ngokucacileyo nezona nkcukacha zincinci zomzimba. Umzekelo:

• Ingqondo yakho kunye nezicubu zemithambo-luvo ezijikeleze yona
• Amalungu esifubeni nasesiswini (njengentliziyo, isibindi, izintso, ipleyini, ipancreas)
• Izicubu zebele
• Umqolo kunye nomqolo
• Amalungu e-pelvic cavity (njenge-bladder, i-uterus, ama-ovari, i-prostate gland)
• Ivazi yegazi
• Ithumba

Ifuneka nini i-MRI?

Ugqirha unokucebisa i-MRI ukuze axilonge izifo ezahlukeneyo okanye ajonge inkqubela phambili yonyango.

Ngeengxaki ezinxulumene nengqondo kunye nomqolo

• Ii-aneurysms zobuchopho
• Iithumba ebuchosheni okanye emgogodleni
• Ukonakala kwengqondo okanye umqolo ngenxa yeengozi
• Imithambo-luvo ecinezelekileyo
• Izifo ze-neurological ezifana ne-'Multiple Sclerosis (MS)'
• Istroke

Kwiingxaki ezinxulumene nentliziyo (iCardiac MRI)

• Ukujonga ukusebenza kwamagumbi entliziyo, iivalvu, kunye nemithambo yegazi
• Ukubona umonakalo entliziyweni emva kokuhlaselwa yintliziyo
• Ukujonga iimeko zentliziyo zokuzalwa

Kwamanye amalungu omzimba

• Ukuchonga amaqhuma esifubeni, esiswini, okanye esinqeni
• Iimeko ezifana nesifo sesibindi (i-cirrhosis)
• Izifo zamathumbu (isifo sikaCrohn, i-ulcerative colitis)
• Ukungaqheleki kwemithambo yegazi

Kwamathambo namalungu

• Usulelo lwamathambo (i-osteomyelitis)
• Amaqhuma ethambo
• Iingxaki ngeediski phakathi kwamathambo omqolo
• Umonakalo wamalungu ngenxa yeengozi

Ngaba i-MRI scan ikhuselekile?

Ewe, i-MRI scan ngokubanzi luvavanyo olukhuselekileyo kakhulu.

Kodwa kukho izinto ezimbalwa ekufuneka uzilumkele:

• Izixhobo zesinyithi: Nangona imagnethi enamandla kumatshini we-MRI ingenabungozi kuwe, inokuchaphazela ezinye izixhobo zesinyithi emzimbeni wakho. Umzekelo, i-pacemaker isenokungasebenzi kakuhle okanye iphume.
• Ukunganyamezelani nolwelo oluchasene ne-contrast: Abanye abantu banokuba ne-allergy kulwelo oluchasene ne-contrast. Nangona kunjalo, ezi zihlala zincinci kwaye iimeko ezinzulu azifumaneki rhoqo.
• Ukukhulelwa: Ulwelo olubonisa umahluko alusoloko lunikwa abafazi abakhulelweyo kuba akukacaci ukuba luza kumchaphazela njani umntwana.

Ngubani ongafanelanga ukuba ahlolwe i-MRI?

Ukuba unenye yezi meko zilandelayo, usenokungakwazi ukwenza i-MRI scan. Ngoko ke, ngokuqinisekileyo kufuneka uxelele ugqirha wakho kunye nengcali eyenza i-MRI ngale nto.

• Izincedisi zomoya zakudala
• Ezinye ii-implants ze-cochlear
• Ezinye iintlobo zeekliphu ezisetyenziselwa imithambo yegazi yobuchopho (iikliphu ze-Aneurysm)
• Izinto ezivuselela imithambo-luvo
• Iimpompo zamayeza ezifakelweyo

Ulungiselela njani i-MRI?

Le yeyona nxalenye ekufuneka uyinike ingqalelo kakhulu.

Izinto ekufuneka uzixelele ugqirha okanye ingcali ngaphambi kokuba kuskenwe:

• Ukuba unezifakelo zesinyithi emzimbeni wakho (umz. amalungu angengowokwenziwa).
• Ukuba unesixhobo se-elektroniki esifana ne-pacemaker okanye i-nerve stimulator.
• Ukuba uneziqwenga zesinyithi (umz. iziqwenga zeembumbulu) ezifakwe emzimbeni wakho ngenxa yengozi yangaphambili.
• Ukuba ukhulelwe okanye ukrokrela ukuba ukhulelwe.
• Ukuba unengxaki yokulala ngecala imizuzu engama-30-60 ngexesha.
• Ukuba une- claustrophobia .

Izinto ongenakukwazi ukuzisa kwigumbi lokuskena:

Kufuneka uzisuse zonke ezi zinto ngaphambi kokuba uziskene, kuba zinokutsalwa yimagnethi yomatshini, zikufudumale, zikubeke esichengeni, okanye zichaphazele umgangatho wemifanekiso.

• Zonke izinto zobucwebe, iiwotshi
• Amakhadi etyala, izixhobo zokuva
• Iihoko zesinyithi, iiphini zeenwele, iiziphu ezikwiimpahla zangaphantsi
• Amazinyo okufakelwa asuswayo
• Ipeni, ibhegi yesandla, iiglasi zamehlo
• Ukubhoboza umzimba
• Iifowuni eziphathwayo, izixhobo ze-elektroniki

Kwenzeka ntoni ngexesha le-MRI scan?

Iskeni idla ngokuthatha imizuzu engama-30 ukuya kwengama-50.

1. Okokuqala, uza kucelwa ukuba unxibe impahla ekhethekileyo oyinikwe sisibhedlele.

2. Emva koko uza kubekwa ebhedini eqhagamshelwe kumatshini we-MRI. Le bhedi iza kufakwa kumatshini.

3. Umatshini wenza ingxolo encinci xa usebenza. Wenza isandi sokucofa okanye sokucofa. Oku kuqhelekile. Baza kukunika ii-earplugs okanye ii-headphones ukukhusela iindlebe zakho.

4. Ukuze ufumane imifanekiso emihle kakhulu, kubaluleke kakhulu ukuhlala ungashukumi de kugqitywe ukuskena.

5. Kuqhelekile ukuba inxalenye yomzimba eskeniweyo ivakale ishushu kancinci.

6. Igosa lezobuchwepheshe lihlala likujongile. Ungathetha nalo. Kwakhona, uya kuba neqhosha elithi 'call button' esandleni sakho. Ukuba uziva ungakhululekanga, licinezele.

Kwenzeka ntoni emva kokuskena?

Ukuba awunikwanga iyeza lokuthomalalisa, akufuneki uphumle emva kokuhlolwa. Ungaya ngqo ekhaya uye kwenza imisebenzi yakho yesiqhelo. Nangona kunjalo, ukuba unikwa iyeza lokuthomalalisa, kuya kufuneka ulinde ixesha elithile ukuze imiphumo yamayeza iphele. Kwakhona, kuya kufuneka umntu eze kukuthatha akuse ekhaya.

Ingcali ye-radiology iza kuhlola imifanekiso yakho, ilungiselele ingxelo, ize iyithumele kugqirha wakho. Ugqirha uza kukuchazela ulwazi olukwingxelo.
