Ingalo ye-CT scan

Iskena sekhompyuter (CT) yengalo yindlela yokucinga esebenzisa i-x-reyi ukwenza imifanekiso enqamlezileyo yengalo.

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 zale mihla "zokujika" zinokuqhuba uviwo zingayekanga.)

Ikhompyuter yenza imifanekiso eyahlukileyo yendawo yengalo, ebizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli ezinemilinganiselo emithathu yengalo zinokwenziwa ngokudibanisa izilayi kunye.

Kuya kufuneka uthe cwaka ngexesha loviwo. Ukuhamba kunokubangela imifanekiso ephosakeleyo. Unokuxelelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.

Iskena kufuneka sithathe kuphela imizuzu eli-10 ukuya kweli-15.

Kwezinye iimvavanyo, kuya kufuneka ukuba ube nedayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuze uhanjiswe emzimbeni ngaphambi kokuba uvavanyo luqale. Umahluko unceda iindawo ezithile ukuba zibonise ngcono kwii-ray.

• Umahluko unokunikwa ngomthambo (IV) osesandleni sakho okanye kwingalo yakho. Ukuba kusetyenziswa umahluko, 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.
• Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha isifo seswekile i-metformin (iGlucophage). Kuya kufuneka uthathe amanyathelo akhethekileyo ukuba ukuleyeza.

Ukuba unobunzima obungaphezu kweepawundi ezingama-300 (135 kilograms), fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima. Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena.

Uya kucelwa ukuba ususe ubucwebe kwaye unxibe ilokhwe yasesibhedlele ngexesha lofundo.

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Umahluko onikezwe nge-IV unokubangela ukutshisa okuncinci, incasa yentsimbi emlonyeni, kunye nokufudumeza komzimba. Oku kuvakalelwa kuyinto eqhelekileyo. Baya kuhamba kwimizuzwana embalwa.

I-CT ngokukhawuleza yenza imifanekiso eneenkcukacha zomzimba, kubandakanya iingalo. Uvavanyo lunokunceda ukufumanisa okanye ukufumanisa isifo:

• Ithumba okanye usulelo
• Unobangela wentlungu okanye ezinye iingxaki esihlahleni, egxalabeni okanye engqinibeni (ngokufuthi xa iMRI ingenakwenziwa)
• Ithambo elaphukileyo
• Ubunzima kunye namathumba, kubandakanya umhlaza
• Ukuphilisa iingxaki okanye izicwili ezibomvu emva kotyando

Iskena se-CT sinokusetyenziselwa ukukhokela ugqirha kwindawo elungileyo ngexesha le-biopsy.

Iziphumo zithathwa njengesiqhelo ukuba akukho ngxaki zibonwa kwimifanekiso.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Utshintsho olwenzakalayo ngenxa yobudala
• Ithumba (ingqokelela yobofu)
• Igazi eligalele engalweni (i-venous thrombosis)
• Amathumba
• Umhlaza
• Ithambo elaphukileyo okanye elaphukileyo
• Umonakalo kwisandla, esihlahleni, okanye kumalungu engqiniba
• Umjikelo
• Ukuphilisa iingxaki okanye ukukhula kwezihlunu ezibomvu emva kotyando

Iingozi ze-CT scan zibandakanya:

• Ukuvezwa kwimitha
• Ukusabela okungahambelaniyo nokwahlula idayi
• Isiphene sokuzalwa ukuba senziwe ngexesha lokukhulelwa

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 nomboneleli wakho kufuneka ulinganise lo mngcipheko ngokubhekiselele kwizibonelelo zokufumana ukuxilongwa ngokuchanekileyo kwingxaki yonyango.

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

• Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine. Umntu one-iodine ye-allergies angaba nesicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye imingxunya xa enikwe olu hlobo lokwahluka.
• Ukuba umahluko uyafuneka, unokufumana ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.
• Izintso zinceda ukususa iodine emzimbeni. Abo banesifo sezintso okanye isifo seswekile banokufuna ukufumana ulwelo olongezelelweyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni.

Ngokuqhelekileyo, idayi inokubangela ukuba ubomi buphendule ngokusongela ubomi obubizwa ngokuba yi-anaphylaxis. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, vumela umqhubi weskena ukuba azi ngoko nangoko. I-Scanners ine-intercom kunye nezithethi ukuze umqhubi akwazi ukukuva ngalo lonke ixesha.
