PET imayimira tomato ya positron , ndipo imatengedwa ngati mtundu wa "mankhwala a nyukiliya". Mayesero a nyukiliya onse ali ofanana pogwiritsira ntchito kachidutswa kakang'ono ka zinthu zowonongeka kuti afotokoze thupi kapena mbali zina za ntchito yake, monga kuthamanga kwa magazi, kagayidwe kamene kagayidwe, kapangidwe ka okosijeni kapena glucose.
Ma X-rays, CT akufufuza ndi MR akugwiritsidwa ntchito kuti awonetse thupi lanu kuti awulule zikhalidwe zomwe zimasiyana ndi maonekedwe awo, kuphatikizapo kuzindikira matenda okhudzana ndi kukula, mawonekedwe ndi malo.
Kufufuza kwa PET kumasiyana malinga ndi mtundu umene wagwiritsidwa ntchito, koma wamba amagwiritsa ntchito shuga ya radioactive kuti azindikire khansa yokhudzana ndi momwe shuga imayambira ndi maselo a khansa.
Kodi PET Scans Yopereka Chiyani?
Kufufuza kwa CT ndi MR kuyesa kupeza zithunzi zabwino za ziwalo zosiyanasiyana za thupi, ndikutulukira nodes owonjezera kapena matumbo . Komabe, nthawi zina zimakhala zovuta kudziwa ngati mtanda kapena misa mu thupi kwenikweni uli ndi maselo otupa mmenemo pokha poyeza kukula kwake ndi mawonekedwe ake. Zilonda zazing'ono zingakhale ndi maselo a khansa, pamene zikuluzikulu zingakhale zopanda kanthu. Kufufuza kwa PET kungathandize kuzindikira maselo a khansa omwe amapezeka muzinthu zooneka bwino. Angathandizenso kudziwa kansara m'madera omwe sanayambe kugwiriridwa ndi kufalikira kwa matendawa. Zonsezi zowona mphamvu zimakhala ndi mbali yotsitsa-ndiko, kuthekera kwa kupeza zabwino zonyenga. Komabe, kudziŵa zochitika ndi zoperewera za PET kumathandiza kutsogolera madokotala omwe amatanthauzira maphunziro awa.
Kugwiritsa ntchito PET Scans kwa Lymphoma
Zolemba za PET zimagwiritsidwa ntchito kwambiri mu lymphoma:
- Zitha kugwiritsidwa ntchito popanga, kapena mapu a matendawa m'thupi lanu, pamodzi ndi mayesero ena monga CT scans.
- Lipoti la PET lothandizira lingathandize kusankha chithandizo chamtundu wanji, monga chemotherapy kapena radiation.
- Ikhoza kusonyeza ngati mtanda pa CT scan uli ndi khansa kapena ayi.
- Zingathandize kuthandizira momwe mukuyankhira mankhwala , pakapita mankhwala enaake.
- Pambuyo pa mankhwala, PET imawunikira kudziwa ngati dera la nkhawa liri ndi maselo a khansa yogwira ntchito kapena minofu yambiri.
Kodi PET Scans Yachita Bwanji?
Kawirikawiri nthawi ndi maola angapo omwe odwala sangathe kudya chirichonse chisanafike nthawi yowunika. Zenizeni za ndondomeko zimadalira mtundu wa PET kufufuza komwe kumachitika. Ngati radiotracer imapatsidwa intravenously, kachilombo koyambitsa jekeseni kamayikidwa asanayambe kukonza. Njira yonse kuyambira pachiyambi mpaka kumapeto ikhoza kutenga maola angapo. Mutha kumvetsera nyimbo pa CD yomwe ikuthandizani kuti mukhale osangalala. Pakatha sewero, mukhoza kuchoka mkati mwa kanthawi kochepa.
Kodi FDG-PET ndi chiyani?
FDG ndi shuga ya Fluoro-deoxy, mtundu wapadera wa shuga wa radioactive yomwe amagwiritsidwa ntchito pa PET. Minofu ya m'mimba imagwiritsa ntchito shuga mwamsanga komanso m'njira zosiyanasiyana. FDG imasonkhanitsa mkati mwa maselo otupa. Momwemonso PET yothetsera imatha kusiyanitsa pakati pa maselo abwino ndi otupa.
Kodi PET Scans Ndi Yofunikira?
Kwa mitundu ina ya lymphoma, ndi zina zochitika zachipatala, zolemba za PET zikuyang'ana mochuluka ngati zofunika.
Chizoloŵezi cholingalira cha kujambulira mayeso mu maselo am'mimba ndi CT. Masakono a CT amakono ali ndi chisankho chabwino kwambiri ndipo amatha kutenga nyamakazi zochepa kwambiri. Kufufuza kwa PET kumagwiritsidwa ntchito makamaka ngati mayeso ena chifukwa cha ubwino wa njirayi. Osati odwala onse amafunika kukhala ndi PET, koma angakhale othandiza nthawi zina, monga pamene CT akuyang'ana mafunso osayankhidwa.
PET Pangani Kusinthasintha Panthawi Yotsatira
Palibe malamulo amtheradi omwe nthawi zambiri PET amawerengera, ngakhale akatswiri akuyesera kubwera pamaganizo pa zochitika zochepa zokhudzana ndi matenda. Kufufuza kwa PET sikuyenera kuchitidwa mobwerezabwereza ngati kuyesa kutsatila.
Zipatala zambiri zimagwiritsa ntchito zizindikiro za CT kuti zitsatire ndondomeko, ndikugwiritsa ntchito PET kuyang'ana pamene akufunikira thandizo lina. Muyenera kulankhula ndi dokotala wanu motsatira ndondomeko ya chipatala.
Zotsatira Zotsatira za PET Scans
Kuchuluka kwa radioactivity mu jekeseni ndi kochepa, koma kuwona kwa PET nthawi zambiri kumaphatikizidwa ndi CT scans zomwe zimapereka mlingo waukulu wa miyezi. Ngakhale kuti pali zoopsa zochokera ku PET ndikuyang'ana poizoni, zoopsa ndi zopindulitsa ziyenera kulemedwa mosamala nthawi zonse. Ngati mukukhala ndi PET / CT scan, ndibwino kuti phindu la phunziroli likuposa kwambiri kuopsa kwa chiwerengero cha dokotala, koma nthawi zonse muyenera kumvetsetsa za ngozi ndi zopindulitsa pamene akugwiritsani ntchito, ndipo funsani funso lililonse lomwe mungakhale nalo.
