Yintoni i-computed tomography, yenzelwe ntoni kwaye yenziwa njani?

Umxholo

• Izibonelelo kunye nezinto ezingalunganga ze-CT

I-computed tomography, okanye i-CT, luvavanyo lomfanekiso olusebenzisa ii-X-ray ukuvelisa imifanekiso yomzimba eqhutywa yikhompyuter, enokuba ngamathambo, amalungu okanye izicwili. Olu vavanyo alubangeli zintlungu kwaye nabani na angalwenza, nangona kunjalo, abasetyhini abakhulelweyo kufuneka ngokukhethekileyo benze ezinye iimvavanyo njengenye indlela yokwenza ikhompyuter yecomputer, enje nge-ultrasound okanye ngemagneti resonance, njengokuvezwa kwemitha kukhulu kwi-tomography.

I-Tomography inokwenziwa kunye okanye ngaphandle kokusebenzisa umahluko, olu luhlobo lolwelo olunokuginywa, lufakwe emthanjeni okanye lufakwe kwi-rectum ngexesha loviwo ukulungiselela ukubonwa kwamalungu athile omzimba.

Ixabiso lekhompyuter ye-tomography yahluka phakathi kwe-R $ 200 kunye ne-R $ 700.00, nangona kunjalo olu vavanyo luyafumaneka kwi-SUS, ngaphandle kwendleko. I-tomography ekhompyutheni kufuneka yenziwe kuphela phantsi kolawulo lwezonyango, njengoko kubandakanya ukuvezwa kwimisebe, enokuba yingozi kwimpilo xa ungenaso isikhokelo esaneleyo.

Umatshini weTomography ohlanganisiweyo

Yenzelwe ntoni

I-tomography ekhompyutheni isetyenziselwa ukunceda ekuchongeni izifo zezihlunu kunye nethambo, ichonge indawo enethumba, usulelo okanye ihlwili, ukongeza ekufumaneni nasekujongeni izifo kunye nokwenzakala. Ezona ntlobo ziphambili zeCT scan yile:

• Ukhakhayi lobugcisa: Kubonakaliswe kuphando lwe-traumas, usulelo, ukopha, i-hydrocephalus okanye i-aneurysms. Funda nzulu ngale mviwo;
• I-Tomography yesisu kunye ne-pelvis: Ucelwe ukuba uvavanye ukuvela kwamathumba kunye namathumba, ukongeza ekuqwalaseleni ukwenzeka kwe-appendicitis, i-lithiasis, i-renal malformation, i-pancreatitis, i-pseudocysts, ukonakala kwesibindi, i-cirrhosis kunye ne-hemangioma.
• I-Tomography yamalungu aphezulu nangaphantsi: Isetyenziselwa ukwenzakala kwezihlunu, ukwaphuka, amathumba kunye nosulelo;
• Tomography yesifuba: Ibonakalisiwe kuphando losulelo, izifo ze-vascular, ukulandelela ithumba kunye nokuvavanywa kwendaleko.

Ngokwesiqhelo, ukuvavanywa kwe-CT kukakayi, isifuba kunye nesisu kwenziwa ngokungafaniyo ukuze kubekho ukubonwa okungcono kwezakhiwo kwaye kunokwenzeka ukwahlula ngokulula iintlobo ezahlukeneyo zethishu.

I-tomography ekhompyutheni ayisoloko iyindlela yokuqala yoviwo lokuqonda isifo, kuba kusetyenziswa imitha ukwenza imifanekiso. Uninzi lwamaxesha ugqirha acebisa, kuxhomekeke kwindawo umzimba, ezinye iimvavanyo ezinje ngeX-reyi, umzekelo.

Ungazilungiselela njani iimviwo

Phambi kokuba kwenziwe i-tomography, kubalulekile ukuba ukhawuleze ngokwesikhokelo sikagqirha, esinokuba ziiyure ezi-4 ukuya kwezi-6, ukuze umahluko ungene ngcono. Ukongeza, kubalulekile ukunqumamisa ukusetyenziswa kwe-metformin yeziyobisi, ukuba iyasetyenziswa, iiyure ezingama-24 ngaphambili kunye neeyure ezingama-48 emva koviwo, njengoko kunokubakho ukuphendula ngokuchaseneyo.

Ngexesha loviwo umntu ulele phezu kwetafile kwaye ungena kuhlobo lwetonela, itamografi, kangangemizuzu eli-15. Olu vavanyo alunakulimaza kwaye alubangeli uxinzelelo, njengoko izixhobo zivuliwe.

Izibonelelo kunye nezinto ezingalunganga ze-CT

Ikhompyuter ye-tomography luvavanyo olusetyenziswa ngokubanzi ukunceda ekuchongeni izifo ezininzi kuba ivumela ukuvavanywa kwamacandelo (amalungu) omzimba, ukubonelela ngemifanekiso ebukhali kunye nokukhuthaza ukwahluka kwezicubu ezahlukeneyo. Ngenxa yokuba luvavanyo olwahluka-hlukeneyo, i-CT ithathwa njengolu vavanyo lokhetho kuphando lobuchopho okanye imiphunga okanye amathumba.

Ukungancedi kwe-CT kukuba uviwo lwenziwa ngokukhutshwa kwemitha, i-X-ray, ethi, nokuba ingekho ngobuninzi bayo, inokuba neziphumo eziyingozi empilweni xa umntu esoloko evezwa kolu hlobo yemitha. Ukongeza, kuxhomekeke kwinjongo yovavanyo, ugqirha unokucebisa ukuba umahluko unokusetyenziswa, onokuthi ube nemingcipheko ethile kuxhomekeke emntwini, njengokuphendula komzimba okanye iziphumo ezinobungozi emzimbeni. Jonga ukuba zeziphi iingozi ezinokubakho kwiimviwo ngokuchaseneyo.
