Kayayyakin Kwafi na Positron

Ana amfani da fasahar Radionuclide a yau da kullum a cikin fasahar nukiliya da hanyoyin bincike na zamani. Ɗaya daga cikin hanyoyin da ake amfani da ita na bincike-bincike na radiation shine haɓakar tashar haɗari. Amfani da irin wannan ganewar asali shine yiwuwar gina samfuri uku na tsarin tafiyar da kwayoyin halitta da gabobin ciki.

Mene ne zubar da zane-zane?

Jigon hanyar ta kasance a cikin kaddarorin positrons (barbashi tare da caji mai kyau). Suna da hanyoyi daban-daban a cikin haɗuwa da radiation mai ƙarfi.

Kafin kwaikwayo na haɓin iska ko PET, wani abu na rediyowa yana injected intravenously, yawanci shi ne ruwan inuwa-18, amma wani lokaci ana amfani da carbon-11, oxygen-15 da nitrogen-13. A wani lokaci mutum yana bukatar ya zauna a cikin hutawa, don haka an rarraba isotopes a jikin jiki. Bayan haka, an sanya mai haƙuri a cikin kayan aiki na musamman, kamar MRI, inda jikinsa ke nunawa zuwa radiation marar kyau. Idan akwai matsala a cikin matakai na rayuwa ko ƙananan halittu, ƙananan yankuna suna tara ƙarin kayan aikin rediyo, wanda aka rubuta ta kayan aiki na kwamfuta. Hanyoyin ƙwayoyin ƙwayoyin ƙwayoyin cuta, da kamuwa da cutar sun bambanta da gabobin lafiya a launi.

A ina ake amfani da yadda ake amfani da hoton kwaikwayo na positron?

Mahimmanci, ana amfani da fasaha da aka bayyana a cikin ganewar asibiti na ciwon daji. PET zai iya gano ciwon daji a farkon lokaci ko mataki na zane, lokacin da babu sauran alamun nunawa. Abin sha'awa, ana amfani da rubutun don gano ciwace-ciwacen daji:

• mahaifa;
• haske ;
• gland;
• ciki.

Hanyar ta ba da kulawa da neoplasms a cikin girman daga 1 mm, da kuma ƙididdigar matakai na matakai. Yana da daraja lura cewa tomography taimaka ƙayyade yadda tasiri chemotherapy ne. Hanyar da aka yi bayan tafarkin magunguna ya nuna ragewa a cikin ayyukan kwayoyin cutar ciwon daji, haɓakawarsu da ci gaba.

Bugu da ƙari, ana amfani da PET a cikin ilimin zuciya don rikodin cututtukan zuciya da cututtukan zuciya, cututtukan ƙwayoyin cuta, ƙuntatawa da maganin jini, sakamakon sakamakon ciwon zuciya da kuma kaucewa, stenosis. Kayan fasaha ya ba da launi na ƙwayar zuciya na zuciya a cikin kashi uku a sassa 60.

Har ila yau, yin amfani da kwamfutar komfurin kwakwalwa na kwakwalwa ta amfani da shi. Sanin asali ta hanyar PET yana ba da damar ganewa:

• mai da hankali neoplasms;
• ciwon daji;
• lalata;
• kwakwalwa;
• Alzheimer ta cuta;
• rashin ciwo;
• maganin rigakafi;
• sakamakon ciwon bugun jini , hare-haren ischemic.

Kamar yadda aikin likita ya nuna, idan ka yi tasiri mai haɗari a lokaci mai tsawo, za ka iya samar da tsarin dacewa da dacewa, wanda sau da yawa ya bambanta daga ka'idojin farfadowa ba tare da gudanar da wannan binciken ba. Bugu da ƙari, ganewar asalin ciwon daji na ciwon daji a wani mataki na farko yana samar da babban nasara a yakin wadannan cututtuka, yana taimaka wajen cimma maganin ciwon daji.

Musamman mahimmanci shine amfani da PET a cikin kwayoyin halitta. Cutar cutar Alzheimer a farkon tsari yana da kyau wajen farfadowa, kuma samfurin bincikar cutar zai taimaka wajen ƙaddamar da yaduwar cututtuka. Jigon farko na jiyya yana ba da raguwa a cikin mutuwar nauyin kwakwalwa da kuma ƙaddamar da aiki na wasu yankunansa.
