I-tomography yekhompyutheni yengqondo - indlela yokuhlolwa kwe-X-ray, evumela ukufumana umfanekiso wento kwimilinganiselo eyahlukeneyo.
Yintoni i-tomography yecomputer yengqondo ebonisa?
Nge-tomography yekhompyutheni yengqondo, izifo ze-gray and white brain brain, iziphazamiso kwimingeni, iinqanawa kunye nezicubu ezijikelezayo zibonakala. I-CT yengqondo iyakunceda ukuchonga i-foci ye-inflammation, ukuchonga izicubu ezinobungozi kunye nezibi, kwaye uhlakulele ukungaqhelekanga kubantwana.
Iinkcazo ngenjongo yenkqubo yokuxilonga zilandelayo:
- ukuxhatshazwa kwintwaphu kunye nokuphulwa okukrokrekileyo kunye ne-bone dislocation okanye umonakalo kwizakhiwo;
- Iingcamango malunga nobukho be-tumor ebuchosheni, i-metastasis kwingqondo;
- iziphazamiso zokujikeleza kwegazi, kubandakanywa, ngenxa yesifo okanye isifo senhliziyo;
- ukuqinisekiswa kobukho (ukungabikho) kwezilwanyana ze-cerebral, ii-aneurysms;
- ukuvuvukala kwengqondo (meningitis, encephalitis)
- ukuhlalutya kwethambo lexeshana ngokunciphisa kakhulu ukuva;
- ukukhubazeka kwezicubu zesifo;
- ukwenza imisebenzi engqondweni.
Okukhethekileyo kukuba kunokwenzeka ukuba uhlolisise i-CT kwanomntu osesimweni esinzima, umzekelo, ngokulimala kwengqondo.
Njengaye ezininzi iinkqubo zokuxilonga i-hardware, i-tomography yesicatshulwa inengqondo ineenkalo ezingqinelanayo, kuquka:
- ukunyamezela kwi-iodine okanye i-ejenti yokuphambana;
- ukukhulelwa, ngakumbi kwi-trimester yokuqala (ii-X-ray zingalimaza umntwana);
- isifo esibuhlungu;
- hyperkinesis (ukunyuswa okungalawulwayo);
- Ukungaphumeleli kwezintso (ngenxa yeengxaki zokutshatyalaliswa ngokungafaniyo).
Ukongezelela, i-tomography ekhompyutheni ayikhuthazwayo kunina osondezayo, kuba ukungafani kulula ukungena kubisi lwebele. Ukuba inkqubo kufuneka iqhutywe, le ntokazi iyaxwayiswa ukuba ngeentsuku ezimbini emva kokubhalwa komntwana umntwana akufanele abele.
Ingaba i-tomography ekhompyutheni yenziwe njani?
Uphononongo lwezakhiwo zengqondo zenziwa ngoncedo lwe-CT scanner kunye ne-X-rays. Ngokuqhelekileyo, i-ejenti yokuxhathisa i-iodine ijojowe kwigazi ukwenzela ukuphucula ukubonakala. Okwangoku, i-tomography ekhompyutheni yokwakheka kwengqondo, enesisombululo esiphezulu sendawo kwaye inike umthwalo we-radiation ophantsi emzimbeni.
Isigulane sisefilibhileni ye-tomograph, esiya kwi-device. Ngaphakathi kwe-scanner, imilayezo iyayicatshulwa, kwaye imifanekiso emnyama-kunye nemhlophe iboniswa kwiskrini kweso
Uluhlu olunzima kakhulu kwaye olubiza kakhulu lweemviwo zengqondo luyi-imagination magnetic resonance (MRI) kunye nepositron emission tomography (PET). Ezi ndlela zenza ukuba sikwazi ukunikela ingqondo kwingcaciso encinci. Ukongeza, kunye ne-PET, imifanekiso yembala yeengqimba zengqondo iveliswa, evumela ukuba ufumane ingxaki echanekileyo.
Yimiphi imiphumo ye-tomography yengqondo?
Ngamanye amaxesha izigulane zenqaba ukwenza i-tomography, ikholelwa ukuba le nkqubo ibangela ingozi enkulu kwimpilo. Enyanisweni, uyilo olukhethekileyo lwefowuni luvumela ukunciphisa umthamo we-radiation ukuya kumncinci, ngoko ke i-tomography yeenqanawa ze-cerebral ngokuqhelekileyo ayisongela impilo yesigulane, nokuba iyenzeka ngokuphindaphindiweyo ixesha elifutshane.
