Chii chinonzi CT scan? CT of nomuzongoza. computed tomography

Nhasi, anenge munhu wose anenge anzwa kombiyuta tomography, nokuda kwayo mukurumbira. Asi vaya riri basa, zvakakosha kuziva zvose zviri CT uye nheyo dzayo kushanda.

tsananguro

Computed tomography (CT) tarisei - rechimanjemanje stratified kudzidza dzemuviri. Zvinonzi kwakavakirwa kombiyuta kuyera uye processing musiyano iri attenuation kuti X-mwaranzi akamendwa zvakasiyana mu arambe achirema yavo. Uchishandisa computed Tomography vakaongorora muviri kunooneka dzakasiyana pamakona, saka zvinokwanisika kuwana chifananidzo zvose pamaberere uye-dimensional matatu fomu.

Kuti aite CT anoshandisa rinokosha X-ray CT scanner. Anosanganisira chinjwa tafura, vachipinda murwere apinda hwomukova kushanda pakuvheneka Unit, sezvamakaropafadzwa sensors vari nemwaranzi uye X-ray chubhu.

Maekisirei nomumvura pakudzidza yomuviri mwaranzi kunova simba sezvo ichipfuura tishu. Rotating pa necheparutivi kuti 360 madhigirii kumativi murwere, X-ray emitter kutarira mugove muviri wake panguva dzakasiyana pamakona. Panguva ino sensors dzinongoda mune mhiri murwere munyaya kutendeuka nemwaranzi simba magetsi nomunhu. Ipapo vanoenda kuburikidza kombiyuta kubudiswa, mugumisiro izvo zvinogona kuonekwa pamusoro Monitor. The vakawana mufananidzo zvidzidzo uye aongorora radiologist, ipapo anonyorera kurekodha svikiro uye Prints navo patepi. The yose tsvakurudzo kwacho asingafariri maminitsi anopfuura 10, asi zvichienderana scanner uye yakananga chirwere mapazi kunodiwa uye kusvika hafu yeawa.

Zvinotarisirwa vasati uye mushure bvunzo

Varwere vakanga agamuchira CT scan, vanoda kuziva: Chii chinonzi CT scan, izvo zvinofanira kuchengetwa asati nzira, panguva uye pashure pacho. Nokuti marudzi ose tarisei Zvinokurudzirwa kuti 2 maawa risati kudzidza kuramba zvokudya nezvokunwa. Nokuti nechirwere nedzimwe nhengo, uye mune zvimwe zviitiko nachiremba zvisarudzo zvinoda intravenous musiyano mumiririri kuvandudza migumisiro pakudzidza. Izvi zvichaita pasvika kupinda chiremba ose Murwere kana CT hofisi zvokurapa mudonzvo.

Zvakakosha kuziva kuti kana murwere ane magetsi, zvemaziso uye rinobva anodyara (prostheses, edare, pacemakers), rimwe zuva risati CT vaiva zvidzidzo uchishandisa barium kuturika, uyewo panguva pamuviri zvakafanira kuzivisa chiremba.

The kudzidza muviri kunofanira isina zvipfeko uye zvishongo. Munguva Kuongorora rakavimbika migumisiro zvaunofanira kuurima, ungafanira mweya-kunhaka kwenguva masekonzi mashoma. Computed tomography - zvachose nyarara bvunzo.

Pashure RT pamwe nomutsinga raitongwa zvinodhaka nokuda kwayo mangwanani kushaya kubva muviri zvakakodzera kwemaawa maviri kuti kutora 2 litres mvura.

Ndezvipi zviratidzo kuti kushandiswa CT?

Computed tomography rinoshandiswa kwava, hunoda kukurumidzirwa, zvokurapa uye chirwere dzokuvhiya, akadai richiona yacho ponji.

Sezvo kuongorora bvunzo zvinokosha kuti CT pamwe kakawanda nomusoro, kunyanya achiperekedzwa kurutsa, nguva nenguva kurasikirwa pfungwa kana pfari, kukuvara mumusoro, uyewo kubvisa oncological chimiro dzidzo.

Pakuongorora kuitwa nokukurumidza mukunyombwa zvakakomba, vakafungira kukuvara zvomukati, tsinga, chirwere ane uropi chokubuda upenyu pangozi.

Kana kuita CT of mudumbu?

Abdominal computed tomography nzvimbo yaishandiswa yakarurama chirwere zvirwere chirwatata, gallbladder, chiropa, rwatata, dumbu, ari lstogo ura.

CT dumbu iri kazhinji kuitwa pamwe nomutsinga raitongwa musiyano mumiriri, sezvo nyoro zvinyama nhengo dzakaoma rokuongorora. Siyanisa kuva pfuma unequally kuunganidza mune nyama siyana, nhengo zvinoita kuti tikwanise kusiyanisa kubva mumwe, izvo anoda kuongororwa zvakarurama.

Zviratidzo izvo vanachiremba vanoti kupedza abdominal CT: kakawanda kurwadziwa abdominal nzvimbo, yellowing ganda uye sclera, kupererwa neropa, zvinoshamisa uremu, paumbwe isinganzwisisiki hunhu, dzakaonekwa nokuda Ultrasound.

Kana nomuzongoza rinoitwa kombiyuta tomography?

chidzidzo ichi rinoshandiswa chaizvo nechirwere kuti zamu chirwere, remuromo uye lumbar nomuzongoza. Zvinopa mukana kuongorora zvose maumbirwo mapfupa, tsinga uye akapfava zvinyama uye kuwana-dimensional matatu mufananidzo.

CT of nomuzongoza rinoitwa zvinotevera nyaya:

• chero kukuvara musana;
• chirwere kubva vachiberekwa anomalies;
• musana zvirwere zvinotapuriranwa hunhu;
• arthritis, osteoporosis;
• kuongorora zvinokonzera kurwadziwa (yekupindurwa ari nomuzongoza, herniated discs);
• bundu metastasis kana pedyo nhengo.

Unofanira kuziva kuti kunyange pashure mwana pakutanga peziso ari zvinokuvadza nomuzongoza, uyewo chero musana marwadzo zvichiratidza kupinda rimwe dzapasi maoko nemakumbo, unofanira kubvunza chiremba wako pakarepo. Chete chiremba pashure kuzviongorora murwere anogona kusarudza nezvokudiwa computed tomography.

Ndezvipi zviratidzo computed tomography pechipfuva?
