Tomography yemutsana - mazuva ano kuongororwa kwezvirwere zvekare

Computer tomography inonyanya kubudirira kupfuura yakasarudzwa radiography. Iko inokubvumira kuti urege kuona chete kuchinja kwekunze mumusana, asi zvakare kuwana mufananidzo wepamusoro (kana zvichidikanwa nekuiswa kwekusiyanisa) zvikamu zveganda rekutenderera nehupamhi hwusingapfuuri 4-5 mm.

Dhaka yakadaro inowanikwa nekujekesa muviri wemunhu (nzvimbo inodikanwa) ne radioactive particles iyo inopinda mukati memasukisi uye ichiendesa kune miviri yakanyatsokwana iyo kuwanda kwechimwe nechimwe chechimwe chinhu chiri pasi pekudzidza. Iyo purogiramu yemakombiyuta inounganidza zvose data kubva kune sensor uye inovabatanidza iyo kuburikidza nekugadzirisa kushandiswa, pane zvakabuda zvichipa mufananidzo wakakwana wekukuvara kana zvirwere nenzira yechinhu chinonzi volumetric. Inogona kumira mumamiriro matatu-dimensional, uye kana zvichidikanwa, nyanzvi ichakwanisa kufungidzira nekuwedzera zvikamu zvega ega.

Iko rudzi rwekuongorora rinokubvumira kuti uone nekukwirira kwakakwana nzvimbo dzakaputika dzemapfupa kana cartilage, uye pamwe nekugona kukanganisa kumutsipa wepelinha inopinda mumugero wepasina.

Tomography yepemusoro inogona kuitika nekuiswa kwepakati uye pasina iyo. Muchiitiko chekutanga, murwere anoudzwa nezvemamwe mamiriro ezvinhu uye nemigumisiro inokonzerwa nekuisa chinhu ichi mumuviri (kurutsira, musoro, kusagadzikana mumuromo). Kazhinji, tomography, chaizvoizvo, pamwe neMRI, inoitwa nehuwandu hwehutungamiri hweanesthetics. Izvi zvinoitika munyaya yekutambudzika kwakanyanya mumurwere, sezvo kuongorora kusasimuka ndicho chinhu chikuru. Kune izvi, inofanira kuwedzerwa kuti murwere haafaniri kunge ane zvinhu zvesimbi, kufanana nekufamba, zvinogona kukanganisa migumisiro yeongororo.

Kubatsira kweCCT ndiko kukwanisa kwekugadzwa kwevanhu vane uremu hunorema, izvo zvinosanganisira kuongororwa kwakajeka uye kunopa nguva yakajeka yezvinetso.

Mushure mekuongororwa, ruzivo rwacho runosvika kune chiremba anoenda, uyo anoona kuoma kwechirwere ichi uye anorayira kurapa kwakakodzera maererano nehutachiona. Pano zvakakosha kuziva kuti pamusana pe tomography, munhu anogona kugumisa pamusoro pekubatsira kwekupindira kwekuvhiya uye kuwedzerwa kwekukurumidza.

Computed tomography yepempa inopiwa kujekesa kuongorora mushure mokugara kwenguva yakareba radiography munyaya yeintervertebral hernia kana inofungidzirwa chirwere uye maitiro ake, pamwe nekuona kuvhara kwemaitiro emutsipa kana kukanganiswa kwemaitiro. Chidzidzo chacho chinogona kugoverwa kuti chione chikamu chokupindira kwezvirwere zvakafanana, uye zvakare mushure mokubatsiridzira kushanda kuti uone hutano hwebasa rakaitwa uye chirongwa chekuporesa (zvisinei kuti masastases uye matumusi ari kubviswa nekudaro).

MRI uye kusiyana kwayo kubva kuC CT

Pane imwe nzira inofanana neyo kuverenga tomography . Iko magnetic resonance imaging yemutsana. Mushure mekunge nzira iyi yakatanga kushandiswa mumakiriniki, CT inowanzoshandiswa kuderedza mazai emvura. MRI inoshandiswa inobva pakubatwa kwechiratidzo chinopindira kune magnetic field inogadzirwa nemutambo. Zvose zvikamu zvemuviri, kusanganisira mapfupa, masumbu, matukisi uye mvura, zvine dhesi yakasiyana yehydrogen maatomu, ayo anewo maitiro akasiyana. Vanogona kusiyaniswa nemutambo weMRI. Iyo kombiyuta, iyo yakagadzirirwa deta yakafanana ye data, inovanzwisisa uye inogadzira mufananidzo mumwe chete wechirwere.

Chiratidzo chekuongorora

Tomography yemutsara inoitwa pakuonekwa kwe intervertebral hernias, kuonekwa kwe scoliosis kana osteoporosis. Pano unogona kuwana zvikamu pamusoro pekukura kwezvisikwa zvepachikafu kana nezvekukuvara kwepamuviri (kukanganiswa kwemapapu, kuputika kana kukanganisika mumagetsi ekudzivirira kana martilages). Mukuwedzera, MRI inoshandiswa kuongorora mishonga nemigumisiro, pamwe chete nekateti neuropi. Kuona midziyo uye chiropa zvakadzama, vanoshandisa kusiyana, izvo zvinotanga mumuviri kuburikidza necatheter.

MRI inowanzoshandiswa mune neurology uye neurosurgery. Imidziyo yakadaro inoponesa upenyu hwevanhu vakawanda, nokuti zvinetso zvakatarwa panguva yakatarwa, zvikamu zvekutanga zvekuputsika, kukuvadzwa kwekare kwakatanga kuzviita, kunogona kuporeswa kana kubviswa, uye izvi zvinowedzera zvakanyanya upenyu hwehupenyu.

Zvidzidzo zvakadai sa tomography yemukona uye MRI, sarudza chiremba. Ndiye iye anoita sarudzo pamusoro pekushanda kwekuita izvi kuongororwa, uye anosarudzawo kuti ndeapi ari maviri akakodzera kumurwere.
