Kungani i-MRI ingeyona into ejwayelekile yokuhlolwa okuphuthumayo?

Emnyangweni wezithombe zezokwelapha, kuvame ukuba neziguli ezine-“uhlu oluphuthumayo” lwe-MRI (MR) ukuze zenze ukuhlolwa, futhi zithi kudingeka zikwenze ngokushesha. Kulesi simo esiphuthumayo, udokotela wezithombe uvame ukuthi, “Sicela wenze i-aphoyintimenti kuqala”. Iyini imbangela?

Okokuqala, ake sibheke ukuthi kukhona yini okuphambene nalokho:

Okokuqala,Iziphazamiso eziphelele

1. Iziguli ezine-pacemakers zenhliziyo, izikhuthazi zemizwa, ama-valve enhliziyo ensimbi yokwenziwa, njll.;

2. Nge-aneurysm clip (ngaphandle kwe-paramagnetism, njenge-titanium alloy);

3. Abantu abanemizimba yangaphandle yensimbi engaphakathi kweso, izimila zendlebe zangaphakathi, i-metal prosthesis, i-metal prostheses, amalunga ensimbi, kanye nemizimba yangaphandle ye-ferromagnetic emzimbeni;

4. Ukukhulelwa kusenesikhathi zingakapheli izinyanga ezintathu zokukhulelwa;

5. Iziguli ezinomkhuhlane omkhulu kakhulu.

Ngakho-ke, yisiphi isizathu esenza i-MRI ingabi nensimbi?

Okokuqala, kunensimu enamandla kazibuthe egumbini lomshini we-MRI, engabangela ukushintsha kwensimbi futhi ibangele ukuthi izinto zensimbi zindize ziye esikhungweni semishini futhi zibangele ukulimala ezigulini.

Okwesibili, insimu enamandla ye-MRI RF ingakhiqiza umphumela wokushisa, ngaleyo ndlela kubangele ukushisa kwezinto zensimbi, ukuhlolwa kwe-MRI, ukusondela kakhulu ensimini yamagnetic, noma ensimini yamagnetic kungabangela ukusha kwezicubu zendawo noma ngisho nokubeka impilo yeziguli engozini.

Okwesithathu, insimu yamagnetic ezinzile nefanayo kuphela engathola isithombe esicacile. Uma kuhlolwa ngezinto zensimbi, izinto zobuciko zasendaweni zingakhiqizwa endaweni yensimbi, okuthinta ukufana kwensimu yamagnetic futhi ayikwazi ukubonisa ngokucacile umehluko wesignali wezicubu ezivamile ezizungezile nezicubu ezingavamile, okuthinta ukutholakala kwesifo.

Okwesibili,Izimo ezihlobene

1. Iziguli ezinezitho zangaphandle zensimbi (izifakelo zensimbi, amazinyo okufakelwa, izindandatho zokuvimbela inzalo), amaphampu e-insulin, njll., okumele zihlolwe yi-MR, kufanele ziqaphele noma zihlole ngemva kokususwa;

2. Iziguli ezigula kakhulu ezidinga ukusebenzisa izinhlelo zokusekela impilo;

3. Iziguli ezine-epilepsy (i-MRI kufanele yenziwe ngaphansi kokulawulwa okugcwele kwezimpawu);

4. Kubantu abane-claustrophobia, uma kudingeka ukuhlolwa kwe-MR, kufanele kwenziwe ngemva kokunikeza isilinganiso esifanele se-sedative;

5. Iziguli ezinobunzima bokubambisana, njengezingane, kufanele zinikezwe imithi yokudambisa efanele ngemva kwalokho;

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

Okwesithathu, buyini ubudlelwano phakathi kwalezi zinto ezingavunyelwe kanye nokungenzi amandla okuzikhukhumeza enuzi aphuthumayo?

Okokuqala, iziguli eziphuthumayo zisesimweni esibucayi futhi zizosebenzisa ukuqapha kwe-ECG, ukuqapha ukuphefumula kanye nezinye izinto nganoma yisiphi isikhathi, futhi iningi lala madivayisi alikwazi ukulethwa egumbini lokubonisa ukukhanya kwamagnetic, futhi ukuhlolwa okuphoqelelwe kunezingozi ezinkulu ekuvikeleni ukuphepha kokuphila kweziguli.

Okwesibili, uma kuqhathaniswa nokuhlolwa kwe-CT, isikhathi sokuskena se-MRI side kakhulu, ukuhlolwa kwekhanda okusheshayo kuthatha okungenani imizuzu eyi-10, ezinye izingxenye zesikhathi sokuhlolwa side kakhulu. Ngakho-ke, ezigulini ezigula kakhulu ezinezimpawu zokungazi lutho, i-coma, ukudinwa, noma ukucasuka, kunzima ukuqeda 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 kokuphahlazeka, ukuwa, njll., ukuze kuncishiswe ukunyakaza kweziguli, uma kungekho ukwesekwa okuthembekile kokuhlolwa, odokotela abakwazi ukunquma ukuthi isiguli siphukile yini, izitho zangaphakathi ziyaqhekeka futhi ziphuma igazi, futhi abakwazi ukuqinisekisa ukuthi kukhona yini imizimba yangaphandle yensimbi ebangelwa ukulimala. Ukuhlolwa kwe-CT kufaneleka kakhulu ezigulini ezinalesi simo ukusiza ukusindisa iziguli okokuqala.

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