Izikhalazo zesigulane sezifo zentlungu rhoqo, ukungcola, ukutshintsha kwintsebenzo yeengqondo kuyisizathu esivakalayo sokudibana neengcali. Ngokuphindaphindiweyo, emva kokuvavanya isigulane nokuqokelela i-anamnesis, ugqirha uncoma ukuba i-computer tomography scan.
I-CT scan ibonisa ntoni?
Abo babelwe inkqubo yokuxilonga, kufuneka ukwazi ukuba yintoni i-CT scan ibonisa ubuchopho.
Imiqondiso yokuqeshwa kwe-CT yengqondo yile:
- ukuxhatshazwa okunxulumene nokuphuka kwamathambo enkkull okanye ukulimala kwizakhiwo zobuchopho;
- i-cerebral hemorrhages;
- krokra ukuba khona kwezicubu okanye i-metastase engqondweni;
- ukuguqulwa kokunciphisa kweethambo zomzimba;
- isifo, isifo senhliziyo;
- ukukhubazeka kweenqwelo ze-cerebral ( aneurysm , njl.)
- iinkqubo zokuvuvukala kumadoda (meningitis, encephalitis, abscess);
- iziphulo zokuphuculwa kwengqondo (i-hydrocephalus, njl.).
Kwakhona, ii-CT zikwabiwa xa zicwangcisa ukusebenza kwengqondo kunye nokubeka esweni imeko yeempahla kunye neengxenye zengqondo emva kokuhlinzwa.
Iyiphi indlela yokubhala i-tomography?
I-tomography yekhompyutheni ibhekisela kwiindlela ezingenabuhlungu kunye neendlela ezikhuselekileyo zophando lwe-hardware.
Ubuchwephesha, inkqubo ye-CT ingachazwa ngale ndlela ilandelayo: uviwo olusebenzisa i-tomography yekhompyutheni likuvumela ukuba ufumane uluhlu lwamacandelo (amathambo) engqondo ngohlobo lweemifanekiso kwi-monitor yeskrini kunye nenani leemifanekiso, ekufundeni apho, ugqirha ufumanisa isifo. Xa kuthathwa i-tomography yesithathu-dimensional, i-CD-ROM ifakwe kwisifundo.
Indlela ephakamileyo ephezulu i-tomography ikhompyutheni, enesisombululo esiphezulu sendawo. Ukongezelela, ukunyuka kwe-tomography kudala umthwalo we-radiation ophantsi emzimbeni.
Ukuze kuhlolwe utshintsho oluthile kwisigaba sokuqala, ngokuhambelana nobungqina bogqirha, i-CT engiography yenzayo-uvavanyo lwezakhiwo zengqondo kunye neenqwelo ze-cerebral esebenzisa isiqhelo esahlukileyo. Enye yeendlela ezitsha zokufumana utshintsho lweentsholongwane ebuchosheni, ukuthetha ngokwemfuziselo, kwi-"embryonic state", yi-positron emission tomography (PET). Xa uqhuba i-PET CT yengqondo kunye ne-myotonin, i-glucose, i-sodium diatrizoate okanye enye enye i-tracer, ukwahlukelwa kwintlaba emzimbeni. Ukunyuka ngokukhawuleza kuzo zonke iisistim kunye nezicubu, i-ejenti eyahlukileyo kwingxininiso enkulu iqokelela kwiindawo apho kukho naziphi iinkqubo zentsholongwane ezenzekayo. Emfanekisweni wengqondo, iinqela ze-tracer zibonakala zibonakala, kwaye oku kunceda ukufumanisa i-pathology ekuqaleni kokuphuhliswa kwayo.
I-Tomogram yengqondo
Ubuninzi bomgubo emfanekisweni bubonakaliswe kumhlophe nangomnyama, kunye nakumthunzi wegrey. Ithambo liyona mininzi kakhulu, kwaye linombala omhlophe kwi-tomogram. Into
Kwiimvumi, i-edema, i-hematomas engaphathekiyo kunye nezinye izifo zengqondo kwi-tomogram, iindawo ezinemibala ebumnyama okanye ilula ngaphezu kwezicubu ezijikelezayo ziyahlukahlukana. Ukongezelela, ii-ventricles, imijelo, njl njll zibonakala ngokucacileyo.
Ngokusekelwe kwimiphumo ye-tomography ekhompyutheni, ugqirha ubhale unyango okanye unikezela ukuthunyelwa kwiproferensi yenkcazo ehambelana nesi sifo.
