I-X-ray ne-MRI ikuvumela ukuba uhlolisise izitho zangaphakathi zomntu ngaphandle kokungenelela ngophengululo. Ngoncedo lwabo, unako ukuchonga iziphene ezincinci kunye neentsholongwane ezincinci. I-spiral computed tomography isekelwe kwimiphumo ye-X-rays, kodwa ikhuseleke ngakumbi kunomdla oqhelekileyo kunye ne-X-rays, kwaye yenza ukuba kunokwenzeka ukudala imodeli enemifanekiso emithathu yesayithi elihlolisisiweyo.
I-multultistical spiral computed tomography
I-Spiral computed tomography isebenza ngokwemiqathango yomshini oqhelekileyo we-X-ray, kodwa ngenxa yokuba i-tube ithotyelwe kwindlela ehambayo, inokukhawuleza ngokukhawuleza kwimihlaba efunekayo, ihamba ngokujikeleza umzimba wesigulane. Yonke idatha ifakwa kwangoko kwikhompyutheni kwaye iyafumaneka ukuba ihlalutye yiingcali. Ngenxa yokuba umzimba wesigulane usepulatifeni ehambayo, eqhubela phambili kwicala elingaphambene ne-scanner, kunokwenzeka ukwenza amacandelo ngamaxesha angama-0.5 millimeters! I-Spiral tomography inezinzuzo ezininzi:
- ukuchaneka okuphezulu;
- irradiation ephantsi;
- ukukhawuleza;
- khu seleko.
Ngenxa yoko, ngemizuzu embalwa unokufumana umfanekiso opheleleyo wezitho zangaphakathi xa kunobungozi obunzima kunye neentsholongwane ezifuna ukungenelela kwangangoko kwintsebenzo, iindawo ezininzi zivumela ukuba uhlolisise indawo efunekayo ukuya kwi-millimeter, ebaluleke kakhulu kwi-neurosurgery. Ukongezelela, i-dose encinci ye-X-ray ukuchazwa kwenza kube lula ukuhlolisisa abantwana abancinci kunye nabasetyhini abakhulelweyo, kwakunye nezigulane ezinzima kakhulu. Ukuchasene kuphela ukuvota i-tomography ekhompyutheni kukukho kwezinto zetsimbi emzimbeni kunye nokusetyenziswa kwezixhobo,
Kuphi na i-tomography esebenzayo?
Uninzi ngokuqhelekileyo ngoncedo lokutshiza i-tomography ekhompyutheni kukho uphando lwendawo ethile, okanye iqumrhu. Ifowuni ikuvumela ukuba ukhethe indawo efunwayo, ngelixa ungabonisi ezinye iindawo zeso siza ukuze imifanekiso ingahlali. I-spiral tomography yesigxina sesisu ibonisa umsebenzi wesisu, amathumbu, i-gallbladder kunye nesibindi ngokwahlukileyo. Oku kukuvumela ukuba ugxininise ingxaki. Ngomnxeba we-tomography ekhompyutheni yengqondo, kunokwenzeka ukufumanisa nokuba i- microstroke , ukubetha inqanawa encinci kunye naziphi na iziphazamiso kwiingqondo ezinama-neuroleptic.
