Tlhatlhobo ea pelo ea computed tomography (CT) ke mokhoa o sebelisang litšoantšo tsa x-ray ho etsa litšoantšo tse hlakileng tsa pelo le methapo ea eona ea mali.

  • Teko ena e bitsoa `` coronary calcium scan '' ha e etsoa ho bona hore na o na le khalsiamo e ngata methapong ea pelo.
  • E bitsoa CT angiography haeba e etsoa ho sheba methapo e tlisang mali pelong ea hau. Teko ena e lekola hore na methapo eo e ea fokotseha kapa ea thiba.
  • Ka linako tse ling tlhahlobo e etsoa hammoho le methapo ea methapo ea pelo ho batla mathata ka meaho eo.

O tla kopuoa ho robala tafoleng e moqotetsane e kenang bohareng ba sekena sa CT.

  • U tla robala ka mokokotlo hlooho le maoto li kantle ho sekena mahlakore ka bobeli.
  • Likarolo tse nyane tse bitsoang li-electrode li beoa sefubeng ebe li hokeloa mochining o rekotang tšebetso ea motlakase oa pelo ea hau. U ka fuoa moriana ho fokotsa lebelo la pelo ea hau.
  • Hang ha o se o le ka hare ho sekena, molamu oa x-ray oa mochini o potoloha ho o potoloha.

K'homphieutha e etsa litšoantšo tse arohaneng tsa sebaka sa 'mele, se bitsoang lilae.


  • Litšoantšo tsena li ka bolokoa, tsa bonoa mochining oa sefofane, kapa tsa hatisoa filiming.
  • Ho ka etsoa meetso ea pelo ea 3D (mahlakore a mararo).

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 kaofela se lokela ho nka feela metsotso e 10.

Litlhahlobo tse ling li hloka hore dae e khethehileng, e bitsoang phapang, e isoe 'meleng pele teko e qala. Phapang e thusa libaka tse ling ho hlaha hantle ho x-ray.

  • Phapang e ka fanoa ka mothapo (IV) letsohong la hao kapa sephakeng. 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.

Pele o fumana phapang:

  • Tsebisa mofani oa hao oa tlhokomelo ea bophelo haeba u kile ua ba le karabelo ea phapang kapa meriana efe kapa efe. O kanna oa hloka ho noa meriana pele ho tlhahlobo hore o fumane ntho ena ka polokeho.
  • Bolella mofani oa hau ka meriana eohle ea hau, hobane o ka kopuoa ho e ts'oara, joalo ka meriana ea lefu la tsoekere metformin (Glucophage), pele ho tlhahlobo.
  • Tsebisa mofani oa hau haeba u na le mathata a liphio. Lintho tse fapaneng li ka etsa hore ts'ebetso ea liphio e mpefale.

Haeba u le boima ba lik'hilograma tse fetang 135, fumana hore na mochini oa CT o na le moeli oa boima. Boima bo bongata haholo bo ka baka tšenyo likarolong tse sebetsang tsa sekena.


O tla kopuoa ho tlosa mabenyane le ho apara moaparo oa sepetlele nakong ea boithuto.

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

Phapang e fanoeng ka IV e ka baka:

  • Ho chesa hanyane
  • Tatso ea tšepe molomong
  • Ho futhumatsa mmele ka mofuthu

Maikutlo ana a tloaelehile 'me hangata a fela ka metsotsoana e seng mekae.

Ka potlako CT e etsa litšoantšo tse qaqileng tsa pelo le methapo ea eona. Teko e kanna ea fumana kapa ea fumana:

  • Plaque buildup methapong ea methapo ea pelo ho tseba kotsi ea lefu la pelo
  • Lefu la pelo ea Congenital (mathata a pelo a teng nakong ea tsoalo)
  • Mathata le li-valve tsa pelo
  • Ho thiba methapo e fanang ka pelo
  • Lihlahala kapa bongata ba pelo
  • Ho pompa ha pelo

Liphetho li nkuoa li tloaelehile haeba pelo le methapo e hlahlojoang e shebahala hantle.

Palo ea "calcium" ea hau e ipapisitse le bongata ba calcium e fumanoang methapong ea pelo ea hau.


  • Teko e tloaelehile (e fosahetse) haeba lintlha tsa calcium ea hau e le 0. Sena se bolela hore monyetla oa ho ba le lefu la pelo lilemong tse 'maloa tse tlang o tlase haholo.
  • Haeba palo ea calcium e le tlase haholo, ha ho bonolo hore u be le lefu la methapo ea pelo.

Liphetho tse sa tloaelehang li ka bakoa ke:

  • Aneurysm
  • Lefu la pelo ea Congenital
  • Boloetse ba methapo ea mali
  • Mathata a li-valve tsa pelo
  • Ho ruruha ha sekoaelo ho potoloha pelo (pericarditis)
  • Ho fokotsa methapo e le 'ngoe kapa ho feta ea methapo ea mali (coronary artery stenosis)
  • Lihlahala kapa bongata bo bong ba pelo kapa libaka tse haufi

Haeba lintlha tsa calcium li phahame:

  • Ho bolela hore o na le calcium buildup maboteng a methapo ea hau ea mali. Hangata hona ke sesupo sa atherosclerosis, kapa ho thatafala ha methapo.
  • Ha lintlha tsa hau li le holimo, bothata bona bo ka ba boima le ho feta.
  • Bua le mofani oa hau ka liphetoho tsa bophelo tseo u ka li etsang ho fokotsa kotsi ea lefu la pelo.

Likotsi tsa litlhahlobo tsa CT li kenyelletsa:

  • Ho pepesetsoa mahlaseli a kotsi
  • Allergic reaction ho bapisa dae

Lisebelisoa tsa CT li u pepesetsa mahlaseli a mangata ho feta li-x-ray tse tloaelehileng. Ho ba le li-x-ray tse ngata kapa litlhahlobo tsa CT ka nako ho ka eketsa menyetla ea hau ea mofetše. Leha ho le joalo, kotsi e tsoang ho "scan" efe kapa efe e nyane. Uena le mofani oa hau le lokela ho lekanya kotsi ena khahlanong le melemo ea ho fumana tlhahlobo e nepahetseng bakeng sa bothata ba bongaka.

Batho ba bang ba na le ho kula ho fapaneng le dae. Tsebisa mofani oa thepa ea hau haeba u kile ua ba le khatello ea maikutlo ho dae e fapaneng ea ente.

  • Mofuta o tloaelehileng ka ho fetisisa oa phapang o fanoang mothapong o na le iodine. Haeba motho ea nang le alejine ea alejiki a fuoa mofuta ona oa phapang, ho nyekeloa kapa ho hlatsa, ho thimola, ho hlohlona kapa maqhubu ho ka hlaha.
  • Haeba u tlameha ho fuoa phapang e joalo, ho ka 'na ha hlokahala hore u nke li-steroid (joalo ka prednisone) kapa antihistamine (joalo ka diphenhydramine) pele ho tlhahlobo. U kanna ua hloka ho nka histamine blocker (joalo ka ranitidine).
  • Liphio li thusa ho tlosa iodine 'meleng. Ba nang le lefu la liphio kapa lefu la tsoekere ba ka hloka ho fuoa maro a eketsehileng kamora tlhahlobo ho thusa ho ntša iodine 'meleng.

Hangata, dae e ka baka tšoaetso e kotsing ea bophelo e bitsoang anaphylaxis. Haeba o na le bothata ba ho hema nakong ea tlhahlobo, o lokela ho tsebisa mokhanni oa scanner hanghang. Mechine e tla le intercom le libui, kahoo motho ea sebetsang a ka u utloa ka linako tsohle.
