Isifuba CT

Isifuba se-CT (esenziwe ngekhompyutha) yindlela yokucinga esebenzisa i-x-reyi ukwenza imifanekiso enqamlezayo yesifuba kunye nesisu esingasentla.

Uvavanyo lwenziwa ngale ndlela ilandelayo:

• Uyakucelwa ukuba utshintshe uyinxibe esibhedlele.
• Ulele kwitafile emxinwa ethi ityibilikise embindini weskena. Nje ukuba ngaphakathi ngaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena.
• Kuya kufuneka uthe cwaka ngexesha loviwo, kuba intshukumo ibangela imifanekiso emnyama. Unokuxelelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.

Uvavanyo olupheleleyo luthatha imizuzwana engama-30 ukuya kwimizuzu embalwa.

Ezinye iiskrini ze-CT zifuna idayi ekhethekileyo, ebizwa ngokuba yintlukwano, ukuba ihanjiswe emzimbeni ngaphambi kokuba uvavanyo luqale. Umahluko uphakamisa iindawo ezithile ngaphakathi emzimbeni kwaye wenze umfanekiso ocacileyo. Ukuba umboneleli wakho ucela ukuskena i-CT ngokungafaniyo nomthambo, uya kuyinikwa ngomthambo (IV) engalweni okanye esandleni sakho. Uvavanyo lwegazi ukulinganisa umsebenzi wakho wezintso lunokwenziwa ngaphambi kovavanyo. Olu vavanyo kukuqinisekisa ukuba izintso zakho zisempilweni ngokwaneleyo ukuba zingacoca umahluko.

Unokunikwa iyeza lokukunceda uphumle ngexesha lovavanyo.

Abanye abantu banezinto ezichasene ne-IV kwaye banokufuna ukuthatha amayeza phambi kovavanyo lwabo ukuze bafumane ngokukhuselekileyo le nto.

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

Ukuba unobunzima obungaphezulu kweepawundi ezingama-300 (i-135 yeekhilogram), kufuneka umboneleli wakho wokhathalelo lwempilo aqhakamshele umqhubi we-scanner ngaphambi kovavanyo. Izikena ze-CT zinomda wobunzima obungaphezulu kwama-300 ukuya kuma-400 eepawundi (100 ukuya kuma-200 eekhilogram). Izikena ezintsha zinokulungiselela ukuya kuma-600 eekhilogram (270 kilograms). Kuba kunzima ukuba i-x-ray idlule kwisinyithi, uya kucelwa ukuba ususe ubucwebe.

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

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

Akukho xesha lokuchacha, ngaphandle kokuba unikwe amayeza okuphumla. Emva kokuvavanywa kwe-CT, ungabuyela kwindlela otya ngayo yesiqhelo, umsebenzi kunye namayeza.

I-CT ngokukhawuleza yenza imifanekiso eneenkcukacha zomzimba. Uvavanyo lunokusetyenziselwa ukufumana umbono ongcono wezakhiwo ngaphakathi kwesifuba. Ukuskena kwe-CT yenye yeendlela ezilungileyo zokujonga izicubu ezithambileyo ezinje ngentliziyo nemiphunga.

Isifuba se-CT sinokwenziwa:

• Emva kokulimala kwesifuba
• Xa kukrokreleka ithumba okanye ubunzima (isuntswana leeseli), kubandakanywa nesidumbu semiphunga esizimeleyo esibonwa kwisifuba x-ray
• Ukuchonga ubungakanani, imilo, kunye nokuma kwamalungu esifubeni nakwisisu esingaphezulu
• Ukujonga ingqokelela yegazi okanye ulwelo emiphungeni okanye kwezinye iindawo
• Ukujonga usulelo okanye ukudumba esifubeni
• Ukujonga amahlwili egazi emiphungeni
• Ukujonga amanxeba kwimiphunga
  

I-Thoracic CT inokubonisa ukuphazamiseka okuninzi kwentliziyo, imiphunga, i-mediastinum, okanye indawo yesifuba, kubandakanya:

• Ukuqhekeka eludongeni, ukwandiswa okungaqhelekanga okanye ibhaluni, okanye ukunciphisa umthambo omkhulu ohambisa igazi entliziyweni (aorta)
• Olunye utshintsho olungaqhelekanga kwimithambo yegazi emiphungeni okanye esifubeni
• Ukwakhiwa kwegazi okanye ulwelo olujikeleze intliziyo
• Umhlaza wemiphunga okanye umhlaza osele uye kwimiphunga usuka kwenye indawo emzimbeni
• Ukuqokelelwa kolwelo olujikeleze imiphunga (ukungxola)
• Ukonakaliswa kunye nokwandiswa kwemimoya emikhulu yemiphunga (bronchiectasis)
• Kwandiswe iindawo nkovu
• Ukuphazamiseka kwemiphunga apho izicubu zemiphunga zitshiswa zize zonakaliswe.
• Ukukrala kwemiphunga
• Umhlaza wesisu
• I-Lymphoma esifubeni
• Amathumba, amaqhuqhuva, okanye amaqhakuva esifubeni

Izikena ze-CT kunye nezinye ii-x-ray zijongwa ngokungqongqo kwaye zilawulwa ukuqinisekisa ukuba zisebenzisa isixa esincinci semitha. Izikena ze-CT zisebenzisa amanqanaba asezantsi emitha ye-ionizing, enokubangela umhlaza kunye nezinye iziphene. Nangona kunjalo, umngcipheko nakuphi na ukuskena okukodwa kuncinci. Umngcipheko unyuka njengoko uninzi lwezifundo lusenziwa.

Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine. Ukuba umntu one-iodine allergies unikwa olu hlobo lokwahluka, isicaphucaphu, ukuthimla, ukugabha, ukurhawuzelela, okanye umngxunya kungenzeka. Kwiimeko ezinqabileyo, idayi inokubangela ukuba ubomi busongele impendulo ebizwa ngokuba yi-anaphylaxis. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, kuya kufuneka wazise umqhubi weskena kwangoko. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.

Kubantu abaneengxaki zezintso, idayi inokuba neziphumo ezinobungozi kwizintso. Kule meko, amanyathelo akhethekileyo anokuthathwa ukwenza idayi eyahlukileyo ikhuseleke ukusetyenziswa.

Ngamanye amaxesha, uvavanyo lwe-CT lusenokwenziwa ukuba izibonelelo zingaphezulu kakhulu kwimingcipheko. Umzekelo, kunokuba ngumngcipheko wokuba ungabinalo uviwo ukuba umboneleli wakho ucinga ukuba unokuba nomhlaza.
