Enye yeendlela ezininzi zanamhlanje, ezifundisayo kunye eziphumelelayo zokuhlolwa kwe-X kwenkqubo ye-nervous man is computed tomography okanye CT yengqondo. Le nkqubo ikuvumela ukuba ufumane umfanekiso wesigcaziso ngcaciso encinci, eyenza lula ukuxilongwa nokunyango olulandelayo.
I-CT yengqondo njani?
Ingundoqo yenkqubo kukuba kwenziwe iifoto ze-X-ray zobuchopho kumacandelo ahlukeneyo usebenzisa i-bridge directional radiation. Ubungakanani bomgca omnye, njengomthetho, luvela kwi-0.5 ukuya kwi-1 mm, eqinisekisa ukuba ukuchaneka kokuchaneka komfanekiso oqulunqiweyo. Ngendlela elula, umfanekiso ogqityiweyo uqokelelwa kwizinto ezilandelelanayo, njengesonka sesonka - ukusuka kwiinketsi ezincinci ezincinci.
Uvavanyo lweengqondo nge-CT:
- Isigulana sisusa nayiphi na into yensimbi kunye neengubo ezivela entloko nasentanyeni.
- Isigulane sibekwe kwindawo engqamlekileyo, kwicala ngalinye lalo mthombo kunye nomkeli we-X-ray (ngendlela yesangqa).
- Intloko ifakwa kwindawo ekhethekileyo ukuqinisekisa ukungahambi kwayo.
- Ngaphakathi kwemizuzu eyi-15-30 imizekelo yeemifanekiso ze-X-ray iveliswa kumaphulo ahlukeneyo.
- Imifanekiso efunyenweyo ifumaneka kwi-monitor yekhompyutheni yecandelo lochwepheshe bezonyango, okunciphisa ngokusebenzisa inkqubo ekhethekileyo.
Kubalulekile ukuqaphela ukuba ngexesha lokufunda isigulane sinokubona yonke into eyenzekayo, ngoko-CT iyindlela ephosakeleyo yokuxilongwa nakwabantu abaphethwe yi-claustrophobia. Ukongezelela, umcedisi webhubhoratri ubeka imeko yengxaki nganye ngomzuzu kwaye, ukuba kuyimfuneko, unokuthetha naye.
I-CT yengqondo ngokuphefumula okanye ukuhlukisana
I-Perfusion ikhompyutha ye-tomography isetyenziselwa ukuxilongwa ngokuchanekileyo kwezifo zesistim se-brain tissues.
Inkqubo ifana ne-CT eqhelekileyo, kodwa ngaphambili, i-100 ukuya kwe-150 ml ye-medium medium ifakwe kwisigulane somguli. Isisombululo sinikwe okanye sisetranshini ngokuzenzekelayo okanye i-dropper.
Kule meko, ukulungiswa kwe-CT yengqondo kuyafuneka - awukwazi ukuthatha ukutya iiyure ezingama-2.5-3 ngaphambi kokuqala kokufunda.
Nge-tomography ngokuxhatshazwa, izigulane ezininzi zivakalelwa ngotshisa kuwo wonke umzimba, ngokukhawuleza emva kwesojojo, kunye neentsimbi zentsimbi zibonakala ngolwimi. Ezi zizinto eziqhelekileyo eziza kutshabalala ngokwazo kwiminithi embalwa.
Imiqondiso ye-CT yengqondo
Kwindlela echazwe ngayo yokuxilongwa ifake isicelo sokukhankanywa kwezi zifo:
- iingxaki emva kokulimala komonakalo kwengqondo;
- ezintle iintloko ezingenakulungeleka unyango lweziyobisi;
- ukuphazamiseka emsebenzini wezitho zengxoxo, ukubona, intetho;
- ukuqhubeka utywala kunye nokuhlanza;
- ingxubusho yengqondo ;
- izicubu kwiisisu zengqondo;
- i-abscess, i-edema ye-cerebral;
- i-atherosclerosis ;
- ukuphazamiseka kwesifo;
- ukunyuka;
- isthmus ye-rhomboid ingqondo;
- aneurysm;
- neuroinfection.
Olu pho nonongo luqhutyelwa ukubeka esweni ukulungelelaniswa nokulandelelaniswa kwimiqathango yonyango ye-encephalitis, umdlavuza kunye ne-toxoplasmosis.
Ukungqinelana kwi-CT yengqondo
Awukwazi ukusebenzisa olu hlobo lophando kwiimeko ezinjalo:
- ukungahambisani nokusetyenziswa kweziyobisi ezine-iodine;
- ukungafihleki kwintlungu
- khulelwa;
- izigaba ezinzulu zesifo sikashukela;
- isisindo somzimba ngaphezu kweekhilomitha ezili-130;
- ubukho beempahla zangaphandle ekhoneni;
- ngaphambili befumene amanani aphezulu e-X ray.
