I-CAT Scan iveza isithombe esiphambanweni seMzimba
I-scan ye-CAT, ebizwa nangokuthi i-axial tomography ye-computer, i-CT scan, noma i-tomography ehlanganisiwe, isilingo esingenasidingo sokuhlola izithombe esetshenziselwa ukuhlonza izimo zezokwelapha. Ukusebenzisa imishini ye-x-ray nama-computer akhethekile, ukuskena kwe-CAT kungakhipha izithombe eziningi ezibukwayo phakathi kwesakhiwo esithile sentshisekelo ngaphakathi komzimba.
Ukusebenza kwe-CAT kuyasebenza kanjani?
Uma unesicingo se-CAT, uzotshelwa ukuthi ulale etafuleni elenzelwe amandla okukuhambisa ekuvulekeni kwesistimu yokucabangela i-CAT.
Ngezinye izikhathi ukuhlolwa kwe-CAT, uzonikezwa idayi enomshini (umehluko) ukusiza ukukhomba imithwalo yegazi namasayithi okuvuvukala. Kukhona umthombo we-x-ray nomtshina ngaphakathi kwezindlu ze-CAT scan imaging system. Umthombo we-x-ray nama-detectors zitholakala ngaphasi komunye nomunye ngendandatho, ebizwa ngokuthi i-gantry, ejikelezayo nxazonke.
Umthombo we-x-ray ukhiqiza uhlaka lwe-x-ray, esimweni somshayeli noma unxantathu, odlula esigabeni somzimba esithwetshiwe. Umtshina, obhekene nomthombo we-x-ray, urekhoda ama-x-rays edlula emzimbeni njengengqikithi yezithombe ezifingqiwe. Izinhlobonhlobo eziningi ezihlukahlukene ziqoqwe kusuka ezingxenyeni ezahlukene zokujikeleza okuphelele komthombo we-x-ray nomtshina. Khona-ke, kuwumsebenzi wekhompiyutha ukuvuselela izithombe ezenziwe ngabanye zibe uchungechunge lwezithombe ezithintekayo zaleso sigaba esithile somzimba, okwenza kube usizo ngezinjongo zokuxilonga.
Ngabe i-Scan ye-CAT ilayishwe?
Iskena se-CAT sikwazi ukunikeza imibono eningiliziwe yazo zonke izinhlobo zamathambo. Kuvame ukulayishwa lapho ulwazi ludingeka ngaphezu kwalokho okungahlinzekiwe nge-x ray evamile. I-scan ye-CAT isetshenziselwa ukuxilonga izimo eziningi zezokwelapha, kuhlanganise nomdlavuza kanye nezifo zamathambo. Kuwusizo nge-arthritis nezimo ze-musculoskelet, futhi, ikakhulukazi ezinkingeni zomgogodla, izandla, nezinyawo, lapho izithombe zamathambo amancane nezicubu ezizungezile (kufaka phakathi imisipha nemithambo yegazi) kubalulekile ukuxilongwa.
Izingozi nezinzuzo ezihambisana ne-CAT Scan
Ngokuvamile, izinzuzo ze-scan ye-CAT yizinqubo ezingenabuhlungu, izinqubo ezingenasidingo ezinikeza ulwazi oluningiliziwe. Ngokungafani ne-x-ray evamile, iskena se-CAT sinikeza izithombe zesisindo esithambile kanye nethambo. Ngokungafani ne-MRI, ukuskena kwe-CAT akuyona into ebucayi ekunyakeni kwakho futhi kungasetshenziswa iziguli ezifake amadivayisi wezokwelapha. Ayikho imisebe ehlala emzimbeni wakho emva kokuskena kwe-CAT. Ingozi eyinhloko ehambisana ne-CAT scan iyichaza emisebeni. Uma ukuskena kwakho kufaka phakathi ukuhlukumeza okungahambi kahle, khona-ke kukhona futhi ingozi encane yokubhekana nokugula kanye / noma izinkinga zezinso. Ezimweni eziningi, izinzuzo zingaphezu kwezingozi.
