Kungani i-MRI Ingeyona Into Ejwayelekile Yokuhlolwa Okuphuthumayo?

Emnyangweni wezithombe zezokwelapha, kuvame ukuba neziguli ezine-MRI (MR) “uhlu lwezimo eziphuthumayo” ukuze zenze ukuhlola, futhi zithi kudingeka zikwenze ngokushesha. Kulesi simo esiphuthumayo, udokotela othwebulayo uvamise ukuthi, “Ngicela wenze i-aphoyintimenti kuqala”. Siyini isizathu?

Okokuqala, ake sibheke contraindications:

Okokuqala,Contraindications ngokuphelele

1. Iziguli ezinezihlinzeki zenhliziyo, ama-neurostimulators, ama-valve enhliziyo ensimbi yokwenziwa, njll.;

2. Ngesiqeshana se-aneurysm (ngaphandle kwe-paramagnetism, njenge-titanium alloy);

3. Abantu abanemizimba yangaphandle yensimbi ye-intraocular, izimila zendlebe yangaphakathi, izitho zokwenziwa zensimbi, izitho zokwenziwa zensimbi, amalunga ensimbi, nemizimba yangaphandle ye-ferromagnetic emzimbeni;

4. Ukukhulelwa kusencane phakathi nezinyanga ezintathu zokukhulelwa;

5. Iziguli ezinomkhuhlane omkhulu kakhulu.

Ngakho-ke, yisiphi isizathu esenza i-MRI ingathwali insimbi?

Okokuqala, kukhona inkambu kazibuthe enamandla ekamelweni lomshini we-MRI, engabangela ukushintsha kwensimbi futhi ibangele izinto zensimbi ukuba indize ziye esikhungweni semishini futhi zidale ukulimala ezigulini.

Okwesibili, inkambu ye-MRI RF enamandla ingaveza umphumela oshisayo, ngaleyo ndlela ibangele ukushisisa kwezinto zensimbi, ukuhlolwa kwe-MRI, eduze kakhulu nendawo kazibuthe, noma kukazibuthe kungabangela ukushiswa kwezicubu zendawo noma kubeke engozini ukuphila kweziguli.

Okwesithathu, insimu kazibuthe kuphela ezinzile futhi efanayo ingathola isithombe esicacile. Uma kuhlolwa ngezinto zensimbi, izinto zobuciko zasendaweni zingakhiqizwa endaweni yensimbi, ethinta ukufana kwendawo kazibuthe futhi ayikwazi ukubonisa ngokucacile umehluko wesignali wezicubu ezizungezile ezivamile nezicubu ezingavamile, ezithinta ukutholakala kwesifo.

Okwesibili,Contraindications isihlobo

1. Iziguli ezinemizimba yangaphandle yensimbi (izimila zensimbi, amazinyo okufakelwa, izindandatho zokuvimbela inzalo), amaphampu e-insulin, njll., okufanele zihlolwe i-MR, kufanele ziqaphele noma zihlole ngemva kokususwa;

2. Iziguli ezigula kakhulu ezidinga ukusetshenziswa kwezinhlelo zokusekela impilo;

3. Iziguli ezinesifo sokuwa (i-MRI kufanele yenziwe ngaphansi kwesisekelo sokulawula okugcwele kwezimpawu);

4. Ezigulini ezine-claustrophobic, uma Ukuhlolwa kwe-MR kudingekile, kufanele kwenziwe ngemva kokunikeza inani elifanele le-sedative;

5. Iziguli ezinobunzima ekusebenzisaneni, njengezingane, kufanele zinikezwe amaphilisi afanele ngemva kwalokho;

6. Abesifazane abakhulelwe nezinsana kufanele bahlolwe ngemvume kadokotela, isiguli kanye nomndeni.

Okwesithathu, buyini ubudlelwano phakathi kwalezi zinkolelo kanye nokungenzi i-nuclear magnetism ephuthumayo?

Okokuqala, iziguli eziphuthumayo zisesimweni esibucayi futhi zizosebenzisa ukuqapha kwe-ECG, ukuqapha ukuphefumula nezinye izinsimbi nganoma yisiphi isikhathi, futhi iningi lala madivayisi alikwazi ukungeniswa ekamelweni le-magnetic resonance, futhi ukuhlolwa okuphoqelelwe kunezingozi ezinkulu ekuvikeleni ukuphepha kokuphila. iziguli.

Okwesibili, uma kuqhathaniswa nokuhlolwa kwe-CT, isikhathi se-MRI scan side, ukuhlolwa kwekhanda elisheshayo nakho kuthatha okungenani imizuzu engu-10, ezinye izingxenye zesikhathi sokuhlolwa zinde. Ngakho-ke, ezigulini ezigula kakhulu ezinezimpawu zokuquleka, i-coma, ukudangala, noma ukuphazamiseka, kunzima ukuqedela i-MRI kulesi simo.

Okwesithathu, i-MRI ingaba yingozi ezigulini ezingakwazi ukuchaza ngokunembile ukuhlinzwa kwazo kwangaphambilini noma omunye umlando wezokwelapha.

Okwesine, ezigulini eziphuthumayo ezihlangabezana nezingozi zezimoto, ukulimala okuphihliza, ukuwa, njll., ukunciphisa ukunyakaza kweziguli, uma kungekho ukwesekwa okuthembekile kokuhlolwa, odokotela abakwazi ukunquma ukuthi isiguli sinokuphuka, ukuphuka kwezitho zangaphakathi nokopha, futhi ayikwazi ukuqinisekisa ukuthi zikhona yini izidumbu zensimbi ezibangelwa ukuhlukumezeka. Ukuhlolwa kwe-CT kufaneleka kakhulu ezigulini ezinalesi simo ukusiza ukusindisa iziguli ngesikhathi sokuqala.

Ngakho-ke, ngenxa yokuhlolwa kwe-MRI, iziguli eziphuthumayo ezisesimweni esibucayi kufanele zilinde isimo esizinzile nokuhlolwa komnyango ngaphambi kokuhlolwa kwe-MRI, futhi kunethemba lokuthi iningi leziguli linganikeza ukuqonda okwengeziwe.
