Okwamuva umdlavuza indlela yokuhlola. Positron ekushayweni tomography. PET scan

Positron ekushayweni ngekhompyutha tomography, noma ama-PET CT - ekutadisheni womuntu izitho zangaphakathi nge radioisotope uphethwe. PET scan ubizwa nangokuthi ezimbili ikhasi lesikhwama sasekhaya ekushayweni tomography, ngenxa yokuthi le ndlela esekelwe ukuthola gamma-ray pair.

PET kuyindlela eziseqophelweni ekuhlonzweni okuba nomdlavuza ngokuphawulekayo, zenhliziyo nezifo zezinzwa. Ngo Oncology PET isetshenziselwa zokuba uchwepheshe wokuhlola izimila ebulalayo, Ukudlulela search eyihlane bese nokuqapha ukwelashwa.

Positron ekushayweni tomography libhekene ukunemba okuphezulu zocwaningo, ubuncane emisebeni ukuchayeka emzimbeni, ithuba lokuhlola zonke izitho ekuhambeleni okukodwa. Lolu cwaningo ngokwawo kobuhlungu ngokuphelele.

PET, ngokungafani nanoma iyiphi enye izindlela zocwaningo, study hhayi izitho yokwakheka nezicubu, futhi yezinqubo zamakhemikhali ezenzeka kuyo. Lapho Oncology chemical izinqubo washintsha, lokhu kungabonakala njengoba ushintsho umbala ukushuba inqubo, sihluke kuyinsakavukela.

Ngakho, ngenxa yokuthi ama-PET ukubona inqubo Cancer iqalwe eside ngaphambi yesimila kwakhiwa. Ultrasound, CT, i-MRI kungathola inkinga kuphela lapho isimila ubonakele kakade futhi bafinyelela usayizi othile (okwesikhathi MRI apharathasi zanamuhla amamilimitha angu hhayi ngaphansi kuka 1-2).

PET izosiza ukucacisa abulalayo noma ingozi isimila, okuyinto kubalulekile ikakhulu lapho kungekho kungenzeka ukuthola biopsy impahla.

PET kuthola ukugeleza kwegazi ezicutshini futhi yakhe izicubu ukusetshenziswa glucose ne-oksijini. umzimba wesiguli sifakwe ethile izidakamizwa enemisebe (glucose enemisebe). I kwemisebe glucose enemisebe eqoshiwe isithwebuli ekhethekile lapho edlulisa lonke ulwazi computer. Izinqubo-computer futhi Ziveza ke.

Amaseli nge umzimba kakhudlwana uqede i-glucose eningi. Kuyinto lokhu ezahlukene amangqamuzana omdlavuza kusukela evamile. Umthombo enemisebe ngaphezulu ishuthiwe izicubu, yilapho bezibona khona abuke isithombe. izigaba maKristu abizwa 'hot ". Ngokuphambene nalokho, ezincane umkhiqizo ethumba - isithombe dimmer etholwe iziza zokuphumula ezinjalo zibizwa ngokuthi "abandayo".

Umzimba izimila abulalayo siphezulu kunamanye e izicubu zomzimba eziphilile. Ngakho-ke, izimila abulalayo ukukhiqiza ngokucace nakakhulu, "hot" isithombe.

Wona-glucose enemisebe onakala esingaphansi kosuku futhi ngokuphelele aqedwa emzimbeni.

Ngenxa yokuthi ama-PET cwaningo ihlanganisa wonke umzimba iyonke, ungakwazi ukwakha uhlelo kunazo olunzulu nokusebenza. Lokhu kuzosusa yonke izicubu onesifo, uma kungenzeka esimweni ngasinye. Okuzothi ngesinye isikhathi kakhulu ukunciphisa ingozi lokubuya kwesifo olwengeziwe.

Ukusebenzisa ama-PET kungaba ngokunembile kwasusa okuba nomdlavuza ngokuphawulekayo, bheka, ngabe wamshaya zamanzi ngaphambi kokuba saqala ukwanda. Lokhu kwenza kube nokwenzeka ukusebenzisa imishanguzo-umdlavuza okuningi ngempumelelo ngaphezulu.

Ekupheleni ngamakhemikhali futhi ukwelashwa ngemisebe PET ukunquma ukuphumelela ukwelashwa.

PET scan kuzoveza metastases lapho ezinye izindlela zokuxilonga ungakabi bakwazi ukwenza kanjalo.

Ngokwesibonelo, ucwaningo yokukhanya ngosizo-X-ray kuyinto esimweni Ukufiphaza imbangela kuphela izinsolo khona metastases. Qinisekisa yobukhona babo yezimanga kuhlasimulise wokubhoboza izicubu noma PET, kodwa i-PET scan eyonquma usayizi Ukudlulela futhi ibona ukusabalala amangqamuzana omdlavuza kusaqalwa lesi sifo.

Ngokungafani scintigraphy, futhi usebenzisa radioisotopes isithombe lapho ngakuthathu PET cwaningo eyenza ukuhlolwa esinembile kakhulu isithombe lesi sifo.

Lolu cwaningo ngokwawo mayelana thelene: isiguli elala phezu kombhede, okuyinto bafakwa umshini. Iyunithi ngokwayo libukeka ngamapayipi esifushane. Inqubo ihlala phakathi isigamu sehora. Ngaphambi kwalokho, isiguli ithola ukuthi uhogele noma ngemithambo yegazi ngokukhethekile walungisa izidakamizwa enemisebe.

Izimo for positron ekushayweni tomography kancane. PET scan contraindicated kubantu besifazane abakhulelwe kanye lactating, kanye nalabo ezigulini bahluleka ukukudambisa, ngaphandle ukunyakaza, uhlale embhedeni isikhathi esidingekayo ukuze kwenziwe ucwaningo.

Positron ekushayweni tomography - Uphenyo ngempela eqolo. Kubiza ruble angu-50 000. ERussia, amalungiselelo ukuze isifundo esinjalo kuphela emadolobheni amakhulu.

Yiqiniso, akunandaba mqondo ukuqhuba PET scan njengoba izivivinyo zokuvimbela umuntu enempilo. Kuyinto esanele ukwenza ukuhlaziywa njalo ngoba isimila iziphambano.

Uma kanti ngokwemvelo bangabantu kancane isimila metastasizes, futhi kulesi simo singaba gcina thina oncomarkers noma ezinye izivivinyo futhi njalo ngihlolwa at oncologist.

Uma isimila isusiwe ku ezigabeni kamuva futhi avame iyakhula ngokushesha ke kunengqondo isifundo PET. Nakuba izindleko ezibonakala okusezingeni eliphezulu cwaningo isiguli uthola ngenxa wonke picture ezenzeka izinguquko emzimbeni wakhe. Kubhekwe le, udokotela angase ukhethe indlela emnene abaningi futhi ngaleyo ndlela engabizi yokwelashwa.

emithi PET scan ngamanani zamanje, ezimweni eziningi, okhokhela uqobo futhi konga izindleko izidakamizwa kuningi kunokomuntu isifundo izindleko uqobo. Ngaphezu kwalokho, isimila izinqubo PET cwaningo iyoba ukutholwa futhi kwavimbela eside ngaphambi kokuthi ngomshini ezinye izindlela ezijwayelekile. Ngenxa yalokho, babangela umzimba wesiguli kuyalimaza kakhulu.

Futhi endabeni izinhlobo ezahlukene lymphoma, ama-PET cwaningo ku linokwethenjelwa nje alikwazi ukushintshwa. Ezinye izindlela zocwaningo nazi kakhulu kunabayeni PET uphethwe, kokubili ukucophelela kanye, futhi Ukudlulela ukuthola izinga.
