Ukuskena iPET

Uvavanyo lwe-positron emission tomography luhlobo lovavanyo lokucinga. Isebenzisa into enemitha yeathom ekuthiwa yitracer ukukhangela izifo emzimbeni.

Iskena se-positron emission tomography (PET) sibonisa indlela amalungu kunye nezicubu ezisebenza ngayo.

• Oku kwahlukile kune-MRI kunye ne-CT scan. Olu vavanyo lubonisa ubume, kunye nokuhamba kwegazi ukuya nokubuya kumalungu.
• Oomatshini abadibanisa imifanekiso ye-PET kunye ne-CT, ebizwa ngokuba yi-PET / CT, zihlala zisetyenziswa.

Iskena se-PET sisebenzisa inani elincinci le-radioactive tracer. I-tracer inikwa nge-vein (IV). Inaliti ihlala ifakwa ngaphakathi kwengqiniba yakho. Umkhondo uhamba egazini lakho kwaye uqokelela kumalungu nakwizihlunu. Oku kunceda i-radiologist ibone iindawo ezithile ngokucacileyo.

Kuya kufuneka ulinde njengoko itracer ifunxwe ngumzimba wakho. Oku kuthatha malunga neyure.

Emva koko, uya kulala kwitafile emxinwa ethe tyibilika ngesikena esikhulu esimilise itonela. I-PET ibhaqa imiqondiso evela kulandelelwano. Ikhompyuter iyitshintsha imiqondiso ibe yimifanekiso ye-3D. Imifanekiso ibonakalisiwe kwisohlo ukuze umboneleli wakho wezempilo ayifunde.

Kufuneka uxoke ulele ngexesha lovavanyo. Ukuhamba kakhulu kunokuphazamisa imifanekiso kwaye kubangele iimpazamo.

Uvavanyo luthatha ixesha elingakanani kuxhomekeke kwiliphi ilungu lomzimba elitshekishwayo.

Unokucelwa ukuba ungatyi nantoni na iiyure ezi-4 ukuya kwezi-6 ngaphambi kokuskena. Uyakwazi ukusela amanzi kodwa azikho ezinye iziselo ezibandakanya ikofu. Ukuba unesifo seswekile, umboneleli wakho uya kukuxelela ukuba ungathathi iyeza lakho leswekile phambi kovavanyo. La mayeza aya kuphazamisa iziphumo.

Xelela umboneleli wakho ukuba:

• Uyayoyika indawo ekufutshane (ine-claustrophobia). Unokunikwa iyeza lokukunceda uzive usozela kwaye ungakhathazeki kangako.
• Ukhulelwe okanye ucinga ukuba unokukhulelwa.
• Unayo nayiphi na i-aleji yedayi ejoyiweyo (umahluko).

Soloko uxelela umboneleli wakho ngamayeza owasebenzisayo. Yazisa umboneleli wakho malunga namayeza owathengileyo ngaphandle kommiselo. Ngamanye amaxesha, amayeza anokuphazamisa iziphumo zovavanyo.

Unokuziva ulwamvila olubukhali xa inaliti ene-tracer ibekwe emthanjeni wakho.

Ukuskena i-PET akubangeli zintlungu. Itafile inokuba nzima okanye ibanda, kodwa ungacela ingubo okanye umqamelo.

I-intercom egumbini ikuvumela ukuba uthethe nomntu nangaliphi na ixesha.

Akukho xesha lokufumana kwakhona, ngaphandle kokuba unikwe iyeza lokuphumla.

Olona hlobo lusetyenziswayo lokuskena i-PET ngumhlaza, xa kunokwenziwa:

• Ukubona ukuba umhlaza usasazeke kangakanani. Oku kunceda ukukhetha eyona ndlela yonyango ilungileyo.
• Ukujonga ukuba umhlaza wakho uphendula njani, nokuba kunyango okanye emva kokugqitywa konyango.

Olu vavanyo lunokusetyenziselwa:

• Jonga ukusebenza kwengqondo
• Chonga umthombo wesifo sokuxhuzula kwingqondo
• Bonisa indawo apho ukungahambi kakuhle kwegazi kuye entliziyweni
• Qinisekisa ukuba ubunzima emiphungeni yakho bunomhlaza okanye abunabungozi

Iziphumo eziqhelekileyo zithetha ukuba bekungekho ngxaki zibonwe kubungakanani, imilo, okanye indawo yelungu. Akukho ndawo apho i-tracer iqokelele ngokungaqhelekanga.

Iziphumo ezingaqhelekanga zixhomekeke kwinxalenye yomzimba ofundwayo. Iziphumo ezingaqhelekanga zinokubangelwa:

• Umhlaza
• Usulelo
• Ingxaki ngokusebenza kwamalungu

Ubungakanani bemitha esetyenzisiweyo kwiskena se-PET simalunga nesixa esilinganayo nesetyenziswa kwizikena ezininzi zeCT. Ezi skena zisebenzisa ii-tracers ezihlala ixesha elifutshane, ke imitha isukile emzimbeni wakho malunga neeyure ezi-2 ukuya kwezi-10. Ukuba ne-x-ray ezininzi, i-CT okanye i-PET ukuskena ngokuhamba kwexesha kunokunyusa umngcipheko womhlaza. Nangona kunjalo, umngcipheko nakuphi na ukuskena okukodwa kuncinci. Wena kunye nogqirha wakho kufuneka ulinganise lo mngcipheko ngokubhekiselele kwizibonelelo zokufumana ukuxilongwa ngokuchanekileyo kwingxaki yonyango.

Xelela umboneleli wakho ngaphambi kolu vavanyo ukuba ukhulelwe okanye uncelisa. Iintsana neentsana ezikhulayo esibelekweni zichaphazeleka ngakumbi yimitha ngenxa yokuba amalungu abo asakhula.

Rhoqo, abantu banokuba neempendulo ezingahambelaniyo nezinto ezilandelwayo. Abanye abantu baneentlungu, ukuba bomvu, okanye ukudumba kwindawo yenaliti.

Kuyenzeka ukuba ube neziphumo ezingezizo kwiskena sePET. Iswekile yegazi okanye amanqanaba e-insulin anokuchaphazela iziphumo zovavanyo kubantu abanesifo seswekile.

Uninzi lwezikena ze-PET ngoku zenziwa kunye ne-CT scan. Olu dibaniso lokudibanisa lubizwa ngokuba yi-PET / CT. Oku kunceda ekufumaneni indawo echanekileyo yethumba.
