Isinus CT scan

Iskena sekhompyuter ye-tomography (CT) yesono luvavanyo lokucinga olusebenzisa ii-x-reyi ukwenza imifanekiso eneenkcukacha ngeendawo ezizaliswe ngumoya ngaphakathi kobuso (iizono).

Uya kucelwa ukuba ulale kwitafile emxinwa ethe tyaba embindini wesikena se-CT. Unokulala ngomqolo, okanye ungalala ubheke phantsi ujonge isilevu.

Nje ukuba ngaphakathi ngaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena. Awuyi kubona i-ray ye-x-ray ejikelezayo. Izikena zale mihla "zokujika" zinokuqhuba uviwo zingayekanga.)

Ikhompyuter yenza imifanekiso eyahlukileyo yendawo yomzimba. Ezi zibizwa ngokuba zizilayi. Imifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. 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. Imitya kunye neepilo zinokusetyenziselwa ukukugcina uthe cwaka ngexesha lenkqubo.

Ukuskena okwenyani kufuneka kuthathe malunga nemizuzwana engama-30. Yonke le nkqubo kufuneka ithathe imizuzu eli-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.
• Yazisa umboneleli wakho ukuba uneengxaki zezintso. Umahluko awunakusetyenziswa ukuba kunjalo.
• Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Kuya kufuneka ukuba uthathe amanyathelo ongezelelweyo ukulungiselela.

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 iimpahla zasesibhedlele ngexesha lokuskena.

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Umahluko onikezwe nge-IV unokubangela:

• Ukutshisa kancinci
• I-Metallic incasa emlonyeni
• Ukufudumeza okufudumeleyo komzimba

Ezi mvakalelo ziqhelekile. Baya kuhamba kwimizuzwana embalwa.

I-CT yakha ngokukhawuleza imifanekiso eneenkcukacha zezono. Uvavanyo lunokufumanisa okanye lubhaqe:

• Iziphene zokuzalwa kwizono
• Usulelo kumathambo ezono (i-osteomyelitis)
• Ukwenzakala ebusweni ngenxa yesono esenzakalisayo
• Ubunzima kunye namathumba, kubandakanya umhlaza
• Iipolyps zempumlo
• Unobangela weempumlo ezinegazi (epistaxis)
• Usulelo lweSinus (sinusitis)

Iziphumo ezivela kolu vavanyo zinokunceda umboneleli wakho acwangcise uqhaqho lwesono.

Iziphumo zithathwa njengesiqhelo ukuba akukho ngxaki zibonwa kwizono.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Iziphene zokuzalwa
• Ukuqhekeka kwamathambo
• Umhlaza
• Iipolyps kwizono
• Usulelo lweSinus (sinusitis)

Umngcipheko wokuvavanywa kwe-CT ubandakanya:

• Ukuvezwa kwimitha
• Ukusabela okungahambelaniyo nokwahlula idayi

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 kakhulu. 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, unokunikwa 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, ke umqhubi unokukuva ngamaxesha onke.
