I-X-ray ne-MRI ikuvumela ukuba uhlole izitho zangaphakathi zomuntu ngaphandle kokungenelela okuhlinzayo. Ngosizo lwabo, ungakwazi ukubona ngisho nokukhubazeka okuncane kakhulu namathologi amancane. I-spiral tomography ehlanganisiwe nayo isekelwe emiphumeleni ye-X-rays, kodwa iphephile kakhulu kune- fluorography evamile kanye ne-X-ray, futhi yenza kube nokwenza imodeli enemininingwane emithathu yesayithi elihloliwe.
I-multistlice evunguza i-tomography ehlanganisiwe
I-compilation tomography esebenza ngokomoya isebenza ngokuvumelana nesimiso somshini ovamile we-X-ray, kodwa ngenxa yokuthi i-tube igxile endleleni ehambayo, ingakwazi ukukhanyela ngokushesha endaweni edingekayo, ihambahamba emzimbeni wesiguli ngokuvunguza. Yonke idatha ivele ibhaliswe kwikhompyutha futhi itholakale ukuhlaziywa yizintatheli. Ngenxa yokuthi umzimba wesiguli usepulatifomu elihambayo, eliqhubekela phambili ekuqondeni okuphambene nesithwebuli, kungenzeka ukwenza izigaba ngezinga elifinyelela ku-0.5 millimeters! I-spiral tomography inezinzuzo eziningi:
- ukunemba okuphakeme;
- irradiation ephansi;
- ukushesha;
- ukuphepha.
Ngenxa yalokho, emaminithini ambalwa ungathola isithombe esiphelele sezitho zangaphakathi uma kwenzeka ukulimala okungathí sina kanye ne-pathologies edinga ukungenelela okusheshayo, ama-multisections akuvumela ukuba uhlole indawo edingekayo kuze kube yi-millimeter, ebaluleke kakhulu ekuhlinzekeni kwegazi. Ngaphezu kwalokho, umthamo omncane we-X-ray ukuchayeka kwenza kube lula ukuhlola izingane ezincane nabesifazane abakhulelwe, kanye neziguli ezisesimweni esibi kakhulu. I-contraindication kuphela yokuvota i-tomography ehlanganisiwe yilapho kubonakala izakhi zensimbi emzimbeni kanye nokusetshenziswa kwezinsimbi,
Kukuphi lapho kusetshenziswa khona i-tomography?
Ngokuvamile ngosizo lokuvota i-tomography ekhompyutheni kukhona ukutadisha indawo ethile, noma isitho. Idivayisi ikuvumela ukuba ukhethe indawo oyifunayo, ngenkathi ungabonisi ezinye izingxenye zesayithi ukuze izithombe zingagxilane. I-spiral tomography yesidumbu sesisu isho umsebenzi wesisu, amathumbu, i-gallbladder nesibindi ngokwehlukana. Lokhu kukuvumela ukuba ugxile enkingeni edingekayo. Ngosizo lokuvuthwa kwe-tomography yombhalo we-computing, kungenzeka ukuthola ngisho ne- microstroke , ukukhipha isitsha esincane kunazo zonke nanoma yikuphi ukuphazamiseka ebuchosheni obunama-neuroleptic.
