Ukukhangelwa kwe-Orbit CT
Iskena sekhompyuter ye-tomography (CT) ye-orbit yindlela yokucinga. Isebenzisa i-x-ray ukwenza imifanekiso eneenkcukacha zeziseko zamehlo (ii-orbits), amehlo kunye namathambo ajikelezileyo.
Uya kucelwa ukuba ulale kwitafile emxinwa ethe tyaba embindini wesikena se-CT. Yintloko yakho kuphela ebekwe ngaphakathi kwiskena se-CT.
Unokuvunyelwa ukuba uphumle intloko yakho emqamelweni.
Nje ukuba ngaphakathi ngaphakathi kwiskena, umatshini we-x-reyi umatshini ujikeleza ngeenxa zonke kuwe kodwa awuyi kubona i-x-ray.
Ikhompyuter yenza imifanekiso eyahlukileyo yommandla womzimba, obizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Ikhompyuter inokwenza iimodeli ezinemilinganiselo emithathu yommandla womzimba ngokubeka iziqwenga kunye.
Kuya kufuneka ulale uthe cwaka ngexesha loviwo, kuba intshukumo ibangela imifanekiso engacacanga. Unokucelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.
Ukuskena okwenyani kuthatha malunga nemizuzwana engama-30. Yonke le nkqubo ithatha malunga nemizuzu eli-15.
Phambi kovavanyo:
- Uya kucelwa ukuba ususe ubucwebe kwaye unxibe ilokhwe yasesibhedlele ngexesha lofundo.
- Ukuba unobunzima obungaphezu kweepawundi ezingama-300 (135 kilograms), fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima. Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena.
Ezinye iimviwo zifuna idayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuba ihanjiswe emzimbeni ngaphambi kovavanyo. Umahluko unceda iindawo ezithile ukuba zibonise ngcono kwii-ray. Umahluko unganikezelwa ngomthambo (ngaphakathi- ngaphakathi- IV) esandleni sakho okanye kwingalo yangaphambili.
Ngaphambi kokuskena usebenzisa umahluko, kubalulekile ukwazi oku kulandelayo:
- Unokucelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-6 phambi kovavanyo.
- Yazisa umboneleli wakho wezempilo ukuba ngaba ukhe wasabela ngokuchaseneyo. Kuya kufuneka uthathe amayeza ngaphambi kovavanyo ukuze ufumane le nto ngokukhuselekileyo.
- Xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Kuya kufuneka uthathe amanyathelo okhuseleko.
- Yazisa umboneleli wakho ukuba unezintso. Kungenxa yokuba umahluko unokuwenza mandundu umsebenzi wezintso.
Abanye abantu banokungonwabi ngokulala etafileni elukhuni.
Umahluko onikezwe nge-IV unokubangela uvakalelo oluncinci lokutsha. Unokuba nencasa yesinyithi emlonyeni kunye nokufudumala okufudumeleyo komzimba. Ezi mvakalelo ziqhelekile kwaye zihlala zihamba kwimizuzwana embalwa.
Olu vavanyo luncedo ekuchongeni izifo ezichaphazela ezi ndawo zilandelayo ngakwiliso:
- Ivazi yegazi
- Imisipha yamehlo
- Imithambo ekhupha amehlo (i-optic nerves)
- Sinuses
Ukuskena i-orbit CT scan kunokusetyenziselwa ukufumanisa:
- Ithumba (usulelo) lommandla wamehlo
- Ithambo lesokile elaphukileyo
- Into yasemzini kwisokethi yamehlo
Iziphumo ezingaqhelekanga zinokuthetha:
- Ukopha
- Ithambo lesokile elaphukileyo
- Isifo samangcwaba
- Usulelo
- Ithumba
Izikena ze-CT kunye nezinye ii-x-ray zijongwa ngokungqongqo kwaye zilawulwa ukuqinisekisa ukuba zisebenzisa isixa esincinci semitha. Umngcipheko ohambelana nayo nayiphi na i-scan nganye iphantsi kakhulu. Umngcipheko unyuka njengoko kusenziwa ezinye izifundo.
Ukuvavanywa kwe-CT kwenziwa xa izibonelelo zingaphezulu kakhulu kubungozi. Umzekelo, kunokuba semngciphekweni kakhulu ukuba ungabinalo uviwo, ngakumbi ukuba umboneleli wakho ucinga ukuba unokuba nomhlaza.
Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine.
- Ukuba umntu one-iodine allergies unikwa olu hlobo lokwahluka, isicaphucaphu, ukuthimla, ukugabha, ukurhawuzelela, okanye umngxunya kungenzeka.
- Ukuba une-allergies eyaziwayo yokuthelekisa kodwa uyidinga kuvavanyo oluyimpumelelo, unokufumana ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.
Izintso zinceda ukuhluza iodine emzimbeni. Ukuba unesifo sezintso okanye isifo seswekile, kuya kufuneka ujongwe ngononophelo kwiingxaki zezintso emva kokuba kunikwe umahluko. Ukuba unesifo seswekile okanye unesifo sezintso, thetha nomboneleli wakho phambi kovavanyo ukuze wazi ubungozi bakho.
Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile (i-Glucophage) kuba ungadinga ukuthatha amanyathelo okhuseleko. Kuya kufuneka uyeke iyeza iiyure ezingama-48 emva kovavanyo.
Kwiimeko ezinqabileyo, idayi inokubangela ukuba ubomi busongele impendulo ebizwa ngokuba yi-anaphylaxis. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, xelela umqhubi weskena ngoko nangoko. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.
