(PET-CT) Izikena

I-Positron Emission Tomography And Computed Tomography (PET-CT) Izikena:

I-PET-CT iyithuluzi elisungulwe kahle lokuxilonga umdlavuza lapho ama-radiotracers e-PET ane-radiolabelled, ngokuvamile i-18F-Fluoro-2 deoxyglucose (18F-FDG), i-molecule kashukela enemisebe ejovwa esigulini. Amangqamuzana omdlavuza agaya ushukela ngamanani aphezulu kunamaseli avamile futhi i-PET-CT scan isiza odokotela ukuthi baqonde ukuthi isimila esingaphakathi emzimbeni sinomdlavuza noma cha. Ucwaningo lwe-PET-CT luhlinzeka ngolwazi olumayelana nesigaba sesifo, ukuze ukuphathwa okufanele njengokuhlinzwa noma ukwelashwa ngamakhemikhali noma ukwelapha ngemisebe kungase kwelulekwe, njengoba kuthathwa njengokufaneleka.

Iskena sisebenzisa udayi okhethekile oqukethe ama-tracer akhipha imisebe (i-Isotope enelebuli yama-molecule e-Glucose). Lawa ma-tracer ayagwinywa, ahogele, noma ajovwe emthanjeni osengalweni kuye ngokuthi iyiphi ingxenye yomzimba ehlolwayo. Izitho ezithile nezicubu zibe sezimunca umkhondo.
Lapho itholwa i-PET scanner, ama-tracer avumela udokotela ukuthi abone ukuthi izitho nezicubu zisebenza kahle kangakanani.
I-tracer izoqoqa ezindaweni zokusebenza kwamakhemikhali aphezulu, okuwusizo ngoba izicubu ezithile zomzimba, nezifo ezithile, zinezinga eliphezulu lomsebenzi wamakhemikhali. Lezi zindawo zezifo zizovela njengamachashaza akhanyayo ku-PET scan

I-Apollo Proton Cancer Center ifakwe ucezu olusha lwe-Siemens Biograph Vision, isithwebuli sokuqala se-Digital PET-CT eSouth East Asia. I-FDG-PET-CT esesikhungweni somdlavuza se-Apollo Proton nayo ingasiza ekutholeni kusenesikhathi ukuphindeka kwesimila. Izikena ze-PET-CT manje sezisetshenziswa ngokwandayo ukuqapha impendulo yokwelashwa kuzo zonke izifo ezibulalayo ezihlukahlukene, ezizokwazi ukuqapha imiphumela yokwelapha futhi zishintshe okufanayo uma kwenzeka isiguli singaphenduli kukho.

Izinzuzo ze-PET-CT Scan:

• Ukutholwa kwezifo kusenesikhathi ngaphambi kokuvela kwezinguquko zesakhiwo.
• Isiteji esinembile kanye nokuvuselelwa kabusha komdlavuza.
• Izingcezu ze-CT ezithuthukisiwe kanyekanye ezingama-64 zomzimba wonke ngolwazi lwe-metabolic.
• Ukulinganisa kwe-tumor metabolism ngaphambi nangemva kokwelashwa.
• Ukuhlelwa kwe-Metabolic yezimila kanye nokubikezela.
• Kuphephile ukusetshenziswa ezigulini ezinesifo sezinso esingamahlalakhona, izimila zensimbi, ama-pacemaker, njll.

Izici Ezimaphakathi Nesiguli:

• Usayizi we-gantry obanzi (78 cms): uhlalisa iziguli ezinkulu.
• Umhubhe omfushane we-gantry (136 cms): uthuthukisa ukunethezeka kwesiguli futhi wenze kube lula ukuma kwesiguli.
• Ukuchezuka kwe-Zero kombhede phakathi kwezinkundla zokubuka ze-PET ne-CT: ukunyakaza okushelelayo kwesiguli kuyo yonke inqubo.
• Amandla aphezulu okuthwala isisindo: Kufika ku-227-kgs

Izici ezikhethekile:

I-crystal ethuthuke kakhulu eNdiya enezimboni zedijithali ezinekhono lokuhlinzeka;

• Ukuzwela okuphezulu kakhulu: Yehlisa isikhathi sokuskena kanye nethamo elijovwe, ithuthukisa ukuphuma kwesiguli, futhi inciphise ukuchayeka kwemisebe ezigulini.
• Okuhamba phambili ekuxazululeni komkhakha: Ingathola izilonda ezincane futhi ibe nomthelela ekuhlolweni kusenesikhathi kwempendulo yokwelashwa.
• Isikhathi esishesha kakhulu sobuchwepheshe bendiza (214 ps): Sithuthukisa ukugqama nesilinganiso sesignali kumsindo.
• I-Flowmotion ne-multi-parametric PET imaging: inika amandla ukulinganisa okuphelele uma kuqhathaniswa ne-SUV kuphela. Inika amandla izithombe eziguqukayo ezinomzimba wonke.
• Ukukhiqizwa kabusha okusheshayo kusuka kudatha yangempela.
• I-4DCT yesango lokuphefumula: Ukuhlelwa okunembile kokwelashwa ngemisebe.
