Ukuskena i-CT

Iskena sekhompyuter ye-tomography (CT) yindlela yokucinga esebenzisa i-x-reyi ukwenza imifanekiso yamacandelo omzimba.

Uvavanyo olunxulumene noko lubandakanya:

• Isisu kunye ne-pelvis CT scan
• I-Cranial okanye intloko ye-CT scan
• Umlomo wesibeleko, i-thoracic, kunye ne-lumbosacral spine CT scan
• Ukukhangelwa kwe-Orbit CT
• Isifuba se-CT scan

Uya kucelwa ukuba ulale kwitafile emxinwa ethe tyaba embindini wesikena se-CT.

Nje ukuba ngaphakathi ngaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena. Izikena zangoku zokuqhuba zinokwenza uviwo ngaphandle kokuma.

Ikhompyuter yenza imifanekiso eyahlukileyo yommandla womzimba, obizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye ikhutshelwe kwidiski. Iimodeli ezinemilinganiselo emithathu yommandla womzimba zinokwenziwa ngokudibanisa izilayi kunye.

Kuya kufuneka uhlale uzolile ngexesha loviwo, kuba intshukumo ibangela imifanekiso engacacanga. Unokuxelelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.

Gcwalisa izikrini zihlala zithatha imizuzu embalwa. Izikena ezitsha zinokufanekisela umzimba wakho wonke kwimizuzwana engaphantsi kwama-30.

Ezinye iimviwo zifuna idayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuba ihanjiswe emzimbeni wakho ngaphambi kokuqala kovavanyo. Umahluko unceda iindawo ezithile ukuba zibonise ngcono kwii-ray.

Yazisa umboneleli wakho wezempilo ukuba ngaba ukhe wasabela ngokuchaseneyo. Kuya kufuneka uthathe amayeza phambi kovavanyo ukunqanda enye impendulo.

Umahluko unokunikwa ngeendlela ezininzi, kuxhomekeke kuhlobo lwe-CT olwenziwa.

• Inokuhanjiswa ngomthambo (IV) esandleni sakho okanye kwingalo yakho.
• Ungasela umahluko ngaphambi kokuskena kwakho. Xa usela umahluko uxhomekeke kuhlobo loviwo olwenziwe. Ulwelo olwahlukileyo lunokungcamla ichalky, nangona ezinye zinencasa. Umahluko uyaphuma emzimbeni wakho ngezitulo zakho.
• Rhoqo, umahluko unokunikezelwa kwi-rectum yakho usebenzisa i-enema.

Ukuba kusetyenziswa umahluko, unokucelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-6 phambi kovavanyo.

Ngaphambi kokufumana umahluko we-IV, xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Abantu abathatha eli yeza banokufuna ukuyeka okwethutyana. Yazisa umboneleli wakho ukuba unayo nayiphi na ingxaki kwizintso zakho. Umahluko we-IV unokuba mandundu ekusebenzeni kwezintso.

Fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima ukuba unobunzima obungaphezulu kweepawundi ezingama-300 (iikhilogram ezili-135). Ubunzima obuninzi bunokonakalisa iskena.

Kuya kufuneka ususe ubucwebe kwaye unxibe igawuni ngexesha lokufunda.

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Umahluko onikezwe nge-IV unokubangela ukuziva uvutha kancinci, incasa yentsimbi emlonyeni, kunye nokufudumeza komzimba. Ezi mvakalelo ziqhelekile kwaye zihlala zihamba ngemizuzwana embalwa.

Ukuskena kwe-CT kudala imifanekiso eneenkcukacha zomzimba, kubandakanya ingqondo, isifuba, umqolo kunye nesisu. Uvavanyo lunokusetyenziselwa:

• Ukuchonga usulelo
• Khokela ugqirha kwindawo elungileyo ngexesha lokuphanda
• Chonga ubunzima kunye namathumba, kubandakanya umhlaza
• Funda imithambo yegazi

Iziphumo zithathwa njengeziqhelekileyo ukuba amalungu kunye nolwakhiwo oluvavanywayo luqhelekile kwinkangeleko.

Iziphumo ezingaqhelekanga zixhomekeke kwinxalenye yomzimba ofundwayo. Thetha nomboneleli wakho malunga nemibuzo kunye neenkxalabo.

Iingozi zokuvavanywa kwe-CT zibandakanya:

• Ukusabela okungahambelaniyo nedayi eyahlukileyo
• Umonakalo ekusebenzeni kwezintso kwidayi eyahlukileyo
• Ukubonakaliswa kwimitha

Ukuskena kwe-CT kukuvezela imitha engaphezulu kwee-ray eziqhelekileyo. Ukuba ne-x-ray okanye i-CT scans ekuhambeni kwexesha kunokunyusa umngcipheko womhlaza. Nangona kunjalo, umngcipheko nakuphi na ukuskena okukodwa kuncinci. Wena kunye nogqirha wakho kufuneka ulinganise lo mngcipheko ngokubaluleka kweenkcukacha eziza kuvela kwi-CT scan. Uninzi loomatshini abatsha bokuskena i-CT banakho ukunciphisa idosi yemitha.

Abanye abantu banesifo sokungafani nedayi. Yazisa umboneleli wakho ukuba ngaba ukhe wafumana into engahambelaniyo nokwahlula idayi.

• Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine. Ukuba une-iodine allergies, umahluko unokubangela isicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye umngxunya.
• Ukuba ngokuqinisekileyo kufuneka unikwe lo mahluko, ugqirha wakho unokukunika ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.
• Izintso zakho zinceda ukususa iodine emzimbeni. Kuya kufuneka ufumane ulwelo olongezelelekileyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni wakho ukuba unesifo seswekile okanye isifo sezintso.

Ngokuqhelekileyo, idayi inokubangela ukuba ubomi buphendule ngokusongela ubomi obubizwa ngokuba yi-anaphylaxis. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, xelela umqhubi weskena ngokukhawuleza. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.
