Siyini-CT scan? CT sokukhubazeka komgogodla. computed tomography

Namuhla, cishe wonke umuntu oye wezwa kuBaba futhi lwekhompuyutha tomography, ngenxa yokuthandwa kwayo. Kodwa labo inikezwa, kubalulekile ukwazi ngokuningiliziwe yini CT kanye isimiso emsebenzini wayo.

Uhlolojikelele

tomography ngekhompyutha (CT) scan - isifundo yesimanje wakubo zomzimba womuntu. Kusekelwe wokulinganisa computer futhi sicubungula umehluko attenuation izindwangu X-radiation, ezahlukene ukuminyana yabo. Ukusebenzisa ngekhompyutha tomography ihlaziye umzimba kubonakala ngezindlela ezihlukahlukene, ngakho-ke kungenzeka ukuthola isithombe wonke projection kanye nefomu ngakuthathu.

Ukuze afeze CT isebenzisa ekhethekile-X-ray CT scanner. Kuhlanganisa itafula ezithathekayo, ngokufaka nesineke ku kuvulwa ukuskena iyunithi, lapho izinzwa kukhona ngemisebe ye-X ray tube.

ukudlula X-ray ngokutadisha womuntu emisebeni umzimba iba buthaka njengoba sidlula izicubu. Ligijima i-engela 360 ezungeza wonke umzimba wesiguli,-X-ray emitter aqalaze ingxenye yomzimba wakhe ngesikhathi engeli lehlukene. Ngalesi sikhathi izinzwa ngokufanele abe kolunye uhlangothi lwawo isiguli ehilelekile ukuguquka amandla emisebe ye-amaza kagesi. Khona-ke baya ngokusebenzisa processing computer, umphumela lapho kungabonwa qapha. I etholwe izifundo isithombe bese ihlaziya radiologist ke ubhalela medium yokuqopha futhi kunyatheliswa kubo on tape. Yonke inqubo yocwaningo kuthatha imizuzu engaphezu kuka-10, kodwa kuncike isithwebuli kanti indawo ethize kutholakala ukuthi uphethwe yini edingekayo futhi kuze kube isigamu sehora.

Izincomo ngaphambi nangemuva kokuhlolwa

Iziguli obamukele scan CT, ufuna ukwazi: Kuyini scan CT, okuyinto izincomo kufanele libukwe ngaphambi inqubo, ngesikhathi nangemva kwalo. Kuzo zonke izinhlobo scan kunconywa amahora ama-2 ngaphambi cwaningo ukuze senqabele ukudla nokuphuzwayo. Ukuze sitholakele izitho ezithile, futhi kwezinye izimo ngumuntu izinqumo udokotela zidinga emthanjeni Ngokuphambene ejenti yokuthuthukisa imiphumela yocwaningo. Lokhu izokwazisa zonke nokuya nesineke udokotela noma ehhovisi abasebenzi bezokwelapha CT.

Kubalulekile ukwazi ukuthi uma isiguli kagesi, mechanical kazibuthe izimila (lokufakelwa kwezitho, izingcwecwe zensimbi ezilula, elawula ukushaya kwenhliziyo), usuku olulodwa ngaphambi CT babe izifundo usebenzisa barium yombala ukumiswa, kanye ngesikhathi sokukhulelwa kubalulekile ukwazisa udokotela.

Ucwaningo we umzimba kufanele ingabi izingubo nezinto zokuhloba. Phakathi Ukuhlola ukuthembeka Imiphumela udinga amanga namanje, kungase kudingeke ukuba umoya-eliyifa imizuzwana embalwa. computed tomography - test ngokuphelele kobuhlungu.

Ngemva RT nge izidakamizwa ngemithambo yegazi iqondiswa ze ukuhoxiswa zalo zokuqala kusukela umzimba kuyadingeka kuze kuphele amahora amabili kuthathe 2 amalitha amanzi.

Yiziphi izinkomba ngokusetshenziswa CT?

computed tomography isetshenziswa njalo, izimo eziphuthumayo, izinqubo zokwelapha kanye kusebenta kwahulumende, ezifana nokuqapha wokubhoboza.

Njengoba ukuhlolwa ukuhlolwa kuyadingeka ukwenza CT ne ikhanda njalo, ikakhulukazi ephelezelwa ukuhlanza, ukulahlekelwa gqwa ukwazi noma ukuquleka, ukulimala ekhanda, kanye ukubekela eceleni uhlamvu oncological lemfundo.

Ocwaningweni eyenziwa unomuzwa wokuphuthuma bathola ukulimala okunzima, esolwa umonakalo esisongela ukuphila kwezitho, imithambo yegazi, sitholakele a haemorrhage ingqondo.

Lapho ukwenza CT esiswini?

Besisu ngekhompyutha tomography isikhala esetshenziselwa ukusazi ngokunembile isifo esikuphethe ukuze izifo ubende, gallbladder, isibindi, amanyikwe, esiswini, le lstogo emathunjini.

CT esiswini ngokuvamile eyenziwa nge ngemithambo yegazi iqondiswa Ngokuphambene ejenti, kusukela soft izicubu zitho nzima ukuhlonza. Phawula umehluko owawukhona phakathi impahla kokuba ngokungalingani buthelela kwezicubu ezahlukene, izitho kwenza kube nokwenzeka ukuhlukanisa komunye nomunye, okuyinto uthanda ukusazi ngokunembile isifo esikuphethe.

Izimpawu okuyiwona odokotela batusa ukuchitha CT besisu: ubuhlungu njalo endaweni besisu, yellowing kwesikhumba futhi sclera, ukuntuleka kwegazi emzimbeni, amadlingozi kwesisindo, kumiswa i nature engaqondakali, Kutsho ultrasound.

Lapho yomgogodla Kwenziwa ikhompyutha tomography?

Lolu cwaningo kabanzi sitholakele isifo webele, wesibeletho kanye lumbar nomgogodla. Lokhu kusinikeza ithuba ukuhlola kokubili isakhiwo amathambo, imithambo yegazi kanye izicubu zomzimba ezithambile kanye ukuthola isithombe ezintathu-ntathu.

CT yomgogodla Kwenziwa kulezi zimo ezilandelayo:

• iyiphi balimala eqolo;
• ukuxilongwa anomalies azalwa naso;
• izifo umgogodla intambo bemvelo samafayela;
• samathambo, ukukhumuzeka kwamathambo,
• ucwaningo izimbangela zobuhlungu (ushintsho yomgogodla, herniated akwazi ukugcina);
• isimila Ukudlulela noma kwezitho eduze.

You azi ukuthi ngisho nangemva ingane efika kuqala ku ukulimala emgogodleni, kanye nanoma yikuphi ubuhlungu emuva imbuthuma kwelinye nemilenze aphansi, kufanele uxhumane nodokotela wakho ngokushesha. Kuphela udokotela sekuhloliwe isiguli onganquma isidingo tomography ngekhompyutha.

Yiziphi izinkomba tomography ngekhompyutha kwesifuba?

CT scanner iye yasetshenziswa ngempumelelo ukuze kuhlonzwe izifo kohlelo eziphathelene nenhliziyo, amathambo kanye nezimbambo thoracic ukuhlola isimo samaphaphu. A scan esifubeni CT kudingekile sitholakele:

• sofuba;
• isimo senhliziyo (khona izimila, izinhlumba, udonga ukujiya);
• patency of imikhumbi emikhulu ekwelapheni isifo senhliziyo;
• lymph node kwesifuba, okuyinto kungabonwa kuphela ngosizo ikhompyutha tomography;
• ukulimala kwamathambo, akwazi ukugcina herniated, izinqubo ukuvuvukala futhi oncological.

Nge ukukhwehlela isikhathi eside, ukujuluka, okungazelelwe kwesisindo, ubuthakathaka jikelele, kanye ukubukeka izinguquko simbe esifubeni radiograph kuyadingeka ukuze njalo xhumana nodokotela isinqumo CT esifubeni. Lolu cwaningo kuzosiza ukuqeda wamaphaphu izimila, isifo sabo okungamahlalakhona, isifo sofuba.

Yiluphi ucwaningo kungcono CT noma i-MRI?

Namuhla, kuzo zombili indlela zokuxilonga lasetshenziswa ngempumelelo uphethwe yini izifo eziningi. Ukuze uqonde ukuthi hlobo luni inhlolovo ngempumelelo, odinga ukukwazi Imibandela yini CT, futhi uhluke kanjani kusukela MRI. Bobabili izinqubo babe ngento eyodwa - ukusetshenziswa indlela ukuskena egqinsiwe zomzimba womuntu. Ngalé kwalokho, awafani futhi akudingeki ezijayelekileko ngokomthetho.

Nge-MRI uqonde kangcono isimo lezi kwezicubu: uqwanga, ekupholiseni izinzwa, imisipha kanye nemisipha, ngakho le ndlela kubalulekile ikakhulukazi neurosurgery. Nokho, kuyinto cishe hhayi ulwazi umdlavuza zokwakheka gallbladder, waphuka amathambo, izimbambo, balimala eqolo, umdlavuza emaphashini.

Kodwa ukusetshenziswa CT ekahle izifo ngenhla. Ukusetshenziswa CT lubaluleke ekutholeni ukulimala skull fresh, besisu futhi izitho thoracic. CT futhi yasetshenziswa ngempumelelo ukuxilonga unhlangothi ngendlela efanele usaqala.

Kulesi sisekelo, singaphetha ngokuthi CT nama-MRI - izindlela ezihlukahlukene zokuhlola, ngamunye okuyinto ebaluleke futhi kubalulekile ngoba ezindaweni ezithile zocwaningo.

Ingabe kuyingozi nocwaningo lwezempilo kukhompyutha tomography?

CT umuntu uthola isilinganiso elincane-X-ray ngemisebe, ngakho ingozi yokuba nemiphumela emibi hhayi kunangendlela esimweni ejwayelekile. Kodwa ukwenqaba lolucwaningo nokuba khona ubufakazi bezokwelatjhwa yingozi empilweni nokuphila isiguli ngenxa yokungabi bikho ukuxilongwa esifike ngesikhathi futhi ethembekile.

Kwabesifazane abakhulelwe i-computer tomography is contraindicated. Nokho, ezimweni ezimbi kakhulu, ezifana bathola ukulimala okunzima, uphethwe Kwenziwa nokubeka iphinifa phambili esiswini wakhe. Ibele kungabhekwa njengophawu contraindication ukuze CT.

Lapho kangcono ukwenza CT scan?

Ngokunemba yi computed tomography kuxhomeke ezicini ezimbili: radiologist efaneleyo, izinga kanye ikhono lobuchwepheshe isithwebuli. Ukuze ucwaninge isicelo multisrezovye, multislice, multidetector ngekhompyutha tomography. Zonke abakhiqizi yalezi amadivaysi nge imodeli ngalinye elisha ufuna ukwandisa umthamo ngemisebe esiphansi.

Udokotela beqhuba ucwaningo oludingekayo ukuze wazi kahle mayelana imigomo futhi butholakala enqubweni eyinkimbinkimbi yokuthela inhlolovo ngamunye. Ngakho-ke, labo abazi kuphi ukwenza CT, singa ukweluleka: izikhungo sina kuphela zokuxilonga onguchwepheshe iphrofayli edingekayo lesi sifo. Sinenkosi imishini yamuva, okunikeza izinga isithombe nge ukuchayeka ubuncane, futhi abasebenzi ongoti isipiliyoni nokuqeqeshwa ukusiza ukwenza uphethwe yini.

Izindleko computed tomography

Lapho kwenziwa ucwaningo lwembulunga, kukhona izinketho akhe amabili yilawa: usebenzisa ejenti Ngokuphambene, futhi ngaphandle kwalo - incike intengo CT. Ngekhompyutha tomography abiza futhi ivumela cwaningo, bomsebenzi endaweni futhi indawo endaweni ukuskena. amasevisi engeziwe kungenziwa emananini: uthumele Imiphumela kudiski, izithombe eziyimpinda, nabanye. Intengo ku CT kungase kuhlobane emtholampilo akhethiwe ocingweni.

isiphetho

Ngakho, ngamafuphi: iyini CT kanye yendima yayo ekuqhubeleni imithi. computed tomography iyindlela yesimanje futhi enemisebenzi-X-ray luhlolo. Usebenzisa ikhompyutha tomography, kungenzeka ukuhlola noma iyiphi ingxenye yomzimba futhi izitho, ukuhlola kwabo ifomu, isikhundla, usayizi, kanye nesakhiwo, ahlaziye ukusebenza kwabo. Izindlela zokusebenzisa i-ejenti Ngokuphambene kwenza esinembile inhlolovo imiphumela.

Izikena we izindlela zakamuva bayakwazi ukuthola izithombe izingqimba thinnest kwezicubu (1-5 mm), okuyinto ikuvumela ukuba ngempumelelo zisebenzisa CT ukuze kuhlonzwe izifo eziningi ezinkulu ngendlela efanele usaqala kanye nokuqapha punctures kanye biopsies, ukwelashwa ngoludala futhi kuhlinzwa. Namuhla, umsebenzi odokotela kakhulu ukukholelwa ngaphandle scan CT.
