Sesebelisoa sa CT (computed tomography) sa sefuba ke mokhoa oa ho nka litšoantšo o sebelisang li-x-ray ho etsa litšoantšo tse fapaneng tsa sefuba le mpa e kaholimo.

Teko e etsoa ka tsela e latelang:

  • Mohlomong u tla kopuoa ho fetola moaparo oa sepetlele.
  • U robala tafoleng e moqotetsane e kenang bohareng ba sekena. Hang ha o se o le ka hare ho sekena, molamu oa x-ray oa mochini o potoloha ho o potoloha.
  • O tlameha o khutsitse nakong ea tlhahlobo, hobane motsamao o baka litšoantšo tse lerootho. U kanna oa bolelloa hore u phefumolohe nako e khuts'oane.

Sesepa se felletseng se nka metsotsoana e 30 ho isa metsotso e seng mekae.

Litekanyetso tse ling tsa CT li hloka dae e khethehileng, e bitsoang phapang, hore e isoe 'meleng pele teko e qala. Phapang e totobatsa libaka tse ikhethang kahare ho mmele mme e etsa setšoantšo se hlakileng. Haeba mofani oa hau a kopa ho hlahlojoa ka CT ka phapano ea methapo, o tla e fuoa ka methapo (IV) letsohong kapa letsohong la hau. Teko ea mali ho lekanya tšebetso ea liphio tsa hau e ka etsoa pele ho tlhahlobo. Teko ena ke ho netefatsa hore liphio tsa hau li phetse hantle ka ho lekana ho sefa phapang.


U ka fuoa moriana ho u thusa ho phomola nakong ea tlhahlobo.

Batho ba bang ba hanana le phapang ea IV mme ba ka hloka ho noa moriana pele ho tlhahlobo ea bona ho fumana ntho ena ka polokeho.

Haeba ho sebelisoa phapang, o ka kopuoa ho se je kapa ho noa letho lihora tse 4 ho isa ho tse 6 pele ho tlhahlobo.

Haeba o le boima bo fetang liponto tse 300 (135 kilograms), kopa mofani oa tlhokomelo ea bophelo bo botle a ikopanye le sesebelisoa sa scanner pele ho tlhahlobo. Mechine ea CT e na le moeli o ka holimo oa boima ba lik'hilograma tse 100 ho isa ho tse 200. Mechine e mecha e ka nka li-kilogramme tse ka bang 600. Hobane ho thata hore x-ray e fete ka tšepe, o tla kopuoa ho tlosa mabenyane.

Batho ba bang ba kanna ba ba le bothata ba ho robala tafoleng e thata.

Phapang e fanoang ka IV e ka baka kutlo e nyane hanyane, tatso ea tšepe molomong, le ho futhumatsa 'mele. Maikutlo ana a tloaelehile 'me hangata a fela ka metsotsoana e seng mekae.

Ha ho na nako ea ho hlaphoheloa ntle le haeba u filoe moriana oa ho phomola. Kamora ho hlahloba CT, u ka khutlela lijong tsa hau tse tloaelehileng, mesebetsing le meriana.


CT kapele e etsa litšoantšo tse qaqileng tsa 'mele. Teko e kanna ea sebelisoa ho bona hantle meaho e kahare sefubeng. CT scan ke e 'ngoe ea litsela tse molemohali tsa ho sheba lisele tse bonolo joalo ka pelo le matšoafo.

Sefuba CT se ka etsoa:

  • Kamora ho tsoa kotsi sefubeng
  • Ha ho belaelloa hlahala kapa boima (lisele tsa lisele), ho kenyeletsoa le nodule ea pulmonary e le mong e bonoang sefubeng sa x-ray
  • Ho tseba boholo, sebōpeho le boemo ba litho tsa 'mele sefubeng le ka mpeng
  • Ho batla pokello e tsoang mali kapa mokelikeli matšoafong kapa libakeng tse ling
  • Ho sheba tšoaetso kapa ho ruruha sefubeng
  • Ho sheba makoala a mali matšoafong
  • Ho batla mabali matšoafong

Thoracic CT e ka bonts'a mathata a mangata a pelo, matšoafo, mediastinum, kapa sebaka sa sefuba, ho kenyeletsoa:

  • Ho taboha leboteng, ho holisa kapa ho balon ho sa tloaelehang, kapa ho fokotsa methapo e meholo e tsoang mali pelong (aorta)
  • Liphetoho tse ling tse sa tloaelehang tsa methapo e meholo ea mali matšoafong kapa sefubeng
  • Ho bokellana ha mali kapa mokelikeli ho potoloha pelo
  • Kankere ea matšoafo kapa mofetše o nametseng matšoafong ho tsoa kae kapa kae 'meleng
  • Pokello ea mokelikeli ho potoloha matšoafo (mokokotlo oa mokokotlo)
  • Tšenyo ho, le ho holisa moea o moholo oa matšoafo (bronchiectasis)
  • Lymph nodes tse atolositsoeng
  • Mathata a matšoafo moo lisele tsa matšoafo li ruruhang ebe li senyeha.
  • Nyomonea
  • Kankere ea Esophageal
  • Lymphoma ka sefubeng
  • Lihlahala, maqhutsu kapa li-cyst sefubeng

Lisebelisoa tsa CT le li-x-ray tse ling li beiloe leihlo le ho laoloa ho netefatsa hore li sebelisa mahlaseli a fokolang. Lisebelisoa tsa CT li sebelisa mahlaseli a kotsi a ionizing, a nang le monyetla oa ho baka mofetše le mathata a mang. Leha ho le joalo, kotsi e tsoang ho "scan" efe kapa efe e nyane. Kotsi e eketseha ha lithuto tse ling tse ngata li etsoa.


Mofuta o tloaelehileng ka ho fetisisa oa phapang o fanoang mothapong o na le iodine. Haeba motho ea nang le allergy ea iodine a fuoa mofuta ona oa phapang, ho nyekeloa ke pelo, ho thimola, ho hlatsa, ho hlohlona kapa hives ho ka hlaha.
