Kodi ndi liti ndipo PET Scans imagwiritsidwa ntchito bwanji khansa ya m'mimba?
Tanthauzo: PET Scan (Positron Emission Tomography)
Kufufuza kwa PET ndiko kuyesa kwasayansi komwe kumagwiritsidwa ntchito poyeza kansa ya mapapo komanso kumagwiritsidwa ntchito limodzi ndi CT.
Kodi PET imawoneka bwanji yosiyana ndi mayesero ena?
Mmene CT imayendera ndi MRI imayang'ana momwe thupi limagwirira ntchito (mafupa, ziwalo ndi ziwalo zina,) PET imafufuza momwe thupi limagwirira ntchito (momwe ziwalozi ndi ziwalozi zikugwirira ntchito.) Pamene CT ndi MRI amawonedwa kuti ndi njira zoganizira zojambula, PET ikuyang'ana njira yopangira mafano.
Zifukwa za PET Scan
Pali zifukwa zingapo zomwe dokotala wanu angapangire PET kusanthula. Ena mwa awa ndi awa:
- Kupeza khansa.
- Kuwona ngati chifuwa chopanda kupweteka chimapezeka ngati khansara kapena m'malo mwake chimawonekera ngati minofu kapena osakhala ndi khansa. Nthaŵi zina, kupima kwa PET kungathe kusiyanitsa pakati pa chotupa chochititsa manyazi ndi chosafunikira popanda kufunika kokhala ndi mapapu.
- Kukhazikitsa khansa pozindikira momwe khansara yathawira kutali. Kansalu ya PET ndi yovuta kwambiri kuposa CT pakuzindikira metastases mu kansa yaing'ono ya m'mapapo ya m'mapapo ndipo ndiyeso lothandiza posiyanitsa khansara yaing'onoting'ono yambiri ya m'mapapo . Kufufuza kwa PET ndibwino kwambiri pofufuza ma lymph nodes omwe ali othandiza kwa khansa. Mwachitsanzo, kupima kwa PET nthawi zina kumatha kudziwa kuti maselo am'kati amatha kupitilira mu mediastinum popanda kufunikira kupanga mediastinoscopy (njira yopaleshoni yomwe ikuyesa kufufuza dera lino.)
- Kukonzekera njira zabwino zothandizira khansa yapakhungu.
- Kuwona momwe mankhwala akugwirira ntchito.
- Kuwunika kuti kansa ya m'mapapo ibwererenso . Mwachitsanzo, zikhoza kukhala zovuta ku CT kudziwa ngati malo ammapapo ali ndi minofu yoopsa chifukwa cha mankhwala opatsirana pogwiritsa ntchito mankhwala kapena m'malo mwake, kubwereka kwa chotupa.
- Kuti athandize kuzindikira kuti matendawa ndi otani. Ziphuphu ndi kuchepa pang'ono kwa shuga zingakhale zovuta kwambiri ndipo zimakhala bwino kwambiri kuposa zomwe zimakhala zowonjezereka.
Ndi khansara yamapapu, kanthana ka PET kawirikawiri kumachitidwa kwa odwala omwe ali ndi kansa ya m'mapapo oyambirira yomwe opaleshoni ikhoza kuchitidwa ndi cholinga chochiza matendawa. Kwa anthu omwe ali ndi khansa yamapapu yomwe yafalikira mopitirira muyezo winawake, opaleshoni si yabwino kwambiri. Mu kafukufuku wina, anapeza kuti mwa anthu asanu mwa anthu asanu aliwonse omwe anali ndi khansa yomwe inkawoneka kuti ikuchiritsidwa, kuyezetsa PET kunakhoza kuzindikira kufalikira kwa khansara zomwe sizinadziwike mwinamwake kotero kuti opaleshoni yosafunikira siinachitike.
PET Scan Procedure
Ndi kupopera kwa PET, shuga pang'ono ya radioactive (fluorodeoxyglucose kapena FDG) imayikidwa mu magazi. Maselo akukula amagwiritsa ntchito shuga. Maselo okula mofulumira monga maselo a kansa amatenga shuga ndipo amatha kuwona pa kujambula kwa magawo atatu.
Asanayambe kujambulira PET, anthu amauzidwa kuti asamadye kapena kumwa (makamaka kudya zakudya za shuga) kwa nthawi ndithu komanso kuchepetsa thupi lawo kwa maola 24. Shuga ya radioactive (fluorodeoxyglucose kapena FDG) imayikidwa, ndipo wodwalayo amadikirira kwa ora kuti thupi lidziwe shuga. Kenaka kuthandizira kumachitika pafupifupi 30 mpaka 60 mphindi.
Zingakhale zochititsa mantha kuganizira za mankhwala osokoneza bongo omwe ali ndi jekeseni m'thupi lanu, koma kwenikweni, kokha kumawoneka poizoni.
Mazirawa amawonongeka mwamsanga pambuyo pa jekeseni, ngakhale akatswiri ena ovomerezeka amalimbikitsa kuti anthu asakhale ndi amayi apakati ndi ana aang'ono patsiku lomwe mayeserowa akuchitidwa.
Zoperewera za PET Scans - Zonama Zowonongeka ndi Zoipa
Monga momwe mayesero ambiri amachitira khansa, pangakhale zotsutsana ndi zonyenga pa PET kufufuza. Cholakwika cholakwika chimakhalapo pamene pali chisokonezo chomwe chilipo, koma sichipezeka pa PET. Chinthu chonyenga chimapezeka pamene kupima kwa PET kumasonyeza kuti chinachake ndi khansara, koma kwenikweni, si kanthu kofunika, monga minofu yambiri. Mavuto omwe amachititsa kuti abodza azikhala ndi khansa yamapapu amatenga matenda a chibayo (post-obstructive pneumonia) (chibayo chomwe chimapezeka m'mapapu kumalo kumene kumakhala chotupa) ndi silicosis.
Malingaliro abodza amapezeka nthawi zambiri m'madera amene machiritso akuchitika, monga malo omwe opaleshoni yachitidwa.
Kawirikawiri, kupima kwa PET kwa khansara yamapapu kumakhala ndi mphamvu zowonongeka komanso zochepa. Kumvetsetsa bwino kumatanthauza kuti mayeserowa ndi othandiza kwambiri pofufuza zovuta zowonongeka, ndipo amatha kusiyanitsa malo oopsa ndi ovulaza omwe ndi ofanana ndi 1 masentimita awiri. Chodziwika bwino chimatanthauza kuti kupeza sikukutanthawuza khansara ndipo zomwe zimachitika monga matenda kapena kutupa kungabweretse nkhawa.
Zitsanzo: Ngakhale kuti jill ya CT yeniyeniyo inalephera kuzindikira khansara yamapapu m'magazi ena osati mapapu ake, kanema yake ya PET inasonyeza kuti khansara yake ya mapapu yakulalika ndipo kuti opaleshoni sichikanakhala chithandizo chabwino kwambiri kwa iye.
