Kuvunguza computed tomography zobuchopho, esifubeni ingaphakathi, emaphashini, izitho besisu

Kusebenta ukwelashwa kuncike ngokuphelele ukunemba uphethwe. Ngokuvamile-ke kwenzeka okuthiwa "amaphutha yezokwelapha" lapho umuntu uqala ukuba aphulukise isifo esihluke ngokuphelele kumzwise umonakalo ongalungiseki emzimbeni. ukwelashwa ngokungalungile ebekiwe kuholela Yiqiniso ezingamahlalakhona lesi sifo noma kuholele ekufeni. Esanda kutholakala kwezokwelapha yasetshenziselwa Kuvunguza computed tomography, okuyinto evumela ukusazi ngokunembile isifo esikuphethe.

Le nqubo

Uyini enjalo computed tomography? Lokhu indlela zobuchwepheshe libhekene izinzuzo eziningi nokunemba esiyingqayizivele. Kulokhu, umphumela udokotela ngokushesha okuningi kunalokho phakathi nezinqubo ejwayelekile.

is kanjani Kuvunguza ngekhompyutha tomography? Phakathi wakhe etafuleni lapho isiguli ukuba ulale siqala ezihambayo ngokushelela futhi kancane. Babalelwa ku-ke ngendlela efanayo ukuze uphendukisa le-X-ray tube ne imitshina inesikhala phezulu.

I-apharathasi uyakwazi siqaphela izimila usayizi encane kakhulu, kuya ku-1 mm. Lokhu kukuvumela ukuhlonza ngokushesha futhi ikhambi lomdlavuza. Iskena eyodwa esifundeni yokwakheka Kwenziwa imizuzu 5, futhi ikhamera laser wenza izithombe esibanzi.

umphumela abasesitelekeni kufinyelelwa ku ngesivinini 64-slice scanner yesimanje - ongaphakeme ezingeni emisebeni ekhiqizwa iyimidwebo futhi ngakuthathu eliphezulu.

ubufakazi

tomography Kuvunguza kuyadingeka kulezi zimo ezilandelayo:

• ucwaningo Brain, lapho udokotela kungathola izingxenye unhlangothi futhi imithambo yegazi abalimele;
• ukuthola ukuvuvukala kule sinuses paranasal;
• esungula kumiswa izimbangela ISIZINDA entanyeni lymph;
• isiqinisekiso uphethwe ngaphambi kokuhlinzwa ukuze esiswini;
• ukuthola izinguquko emaphashini;
• ukuxilongwa hernia intervertebral.

izinzuzo

Kuvunguza CT kunezinzuzo ezithile phezu izindlela ezivamile ucwaningo:

• Iskena (ukuhlangana) kuyashesha kakhulu. Encwadini esifushane Ukwakheka kwezitho ezithile yokwakheka esifundeni isithombe, lapho ikhwalithi yesithombe kuphezulu kakhulu.
• izithombe Spatial 3D kunembe kakhulu, futhi amamodeli ngakuthathu ukukhombisa indawo ethize zokugula. Ukusebenzisa amasu scan Helical angayihlola Umthambo isifo sokuvuvukala kwemithambo ukuhlonza izitsha, ubude bawo, olugcwele.
• Non-koda uma kuqhathaniswa ne myelography, ventriculography.
• Izithombe azilandelani zobuciko ebonakalayo egazini.
• Njengoba eqhathaniswa tomography ezivamile encishisiwe ukuchayeka isiguli-X-ray.

inqubo kanjani?

4 amahora ngaphambi scan wenziwa, awukwazi baphuze futhi badle. Ngezinye izikhathi isiguli iyadingeka ngaphambi luhlolo kwezitho ezithile ukuthi uphuze i-ejenti ukuze kuvele umehluko.

Ukuze wenze scan Kuvunguza CT, isiguli kufanele ulale etafuleni, okuyinto ezithathekayo, ngakho wagingqa emhubheni ekhethekile. Ukuze uphenyo ngokunethezeka, itafula ifakwe ezizibeni akhethekile pads. Lokhu kusiza ngesikhathi luhlolo ukuze kukhawulwe ukuhamba kwayo kuya izithombe Kwatholakala hhayi ukufiphala noma zibe nezinhlamvu.

Labo ezigulini ngasizathu simbe hhayi amanga namanje isikhathi eside futhi isikhathi esifushane ukuze babambe umoya, sedatives iqondiswa.

Ngo kwelinye igumbi kuyinto isiteshi ikhompyutha, ngemuva okuyisona esiphethe udokotela-engineer, usebenzisa esibukweni umphathi isithwebuli futhi unikeza isiqondiso nesineke.

Kuvunguza computed tomography kubhekwa kuphephile. Ngesikhathi inqubo luhlolo isiguli uthola inani elincane X-ray, kodwa incane kangangokuba akubangi ukulinyazwa emzimbeni.

Izimo

Kukhona ingozi ukusabela iguliswa, lapho isiguli iqondiswa-ejenti Ngokuphambene, noma sine.

Uma isiguli uhlushwa isifuba somoya, isifo sikashukela, isifo sezinso, yegilo noma isifo senhliziyo, kumelwe qiniseka yazisa udokotela.

Le nqubo is contraindicated kubantu besifazane abakhulelwe. Uma kwenziwe esimweni ikhava esiswini phambili sihlangu sibalulekile ngempela. Liphinde sinqatshiwe ahlolisise labo iziguli elawula ukushaya kwenhliziyo, izimila ferromagnetic futhi enesisindo esingamakhilogremu angaphezu 130 kg.

Ukuhlola ngaphakathi komgodi ongaphakathi kwamathumbu

Kuvunguza computed tomography we komgodi ongaphakathi kwamathumbu ikuvumela ukuba ubone isithombe esicacile multi-ungqimba kwezitho ezifana ubende, isibindi, amanyikwe kanye nabanye. Chitha ke esimweni uma isiguli ekhononda ka ubuhlungu ukhalo, esiswini, futhi kwezinye izifo emathunjini amancane futhi ikholoni.

Ngaphezu kwalokho, inqubo kuyadingeka ukuze kuhlonzwe:

• appendicitis, diverticulitis, pyelonephritis, amatshe esinyeni nezinso;
• isibindi sibe sesomile, pancreatitis, ukopha zangaphakathi, ama-polyp kanye ukuvuvukala esiswini;
• izimila umdlavuza we komgodi ongaphakathi kwamathumbu;
• izifo-lymph kanye imithambo yegazi.

Kuvunguza computed tomography esiswini Kwenziwa nokusetshenziswa oyisibopho Ngokuphambene ejenti.

wamaphaphu luhlolo

Le nqubo kuyadingeka ukuze ukuthola umdlavuza wamaphaphu metastases. Kuvunguza ngekhompyutha wamaphaphu imaging inikezwa uma kukhona zonke izimpawu umdlavuza kwazo lezi zitho, ufake u-X-ray wayengakwazi ukunikeza ulwazi olunembile ngakho. Ngaphezu kwalokho, ukuhlolwa ezinqunyiwe isifo sofuba, iphaphu abscesses, izinhlumba wamaphaphu yisinanakazana, sarcoidosis, inyumoniya.

Ngaphambi ofeza inqubo, isiguli iqondiswa-ejenti Ngokuphambene emthanjeni equkethe iodine. Uma kusho kukhona njengemithi yokungezwani komzimba nokuthile, kufanele wazise udokotela wakho.

luhlolo zobuchopho

I Helical computed tomography zobuchopho is kabanzi sitholakele yokulimala kabi kakhulu ezinzima futhi ikhanda, nge umfutho ophakeme intracranial, izinguquko kwegazi. Idivayisi uyakwazi ukubona izimo zokucabanga okubangelwa isifo (izimila, abscesses, temlomo), okuyinto kwi tomograph ezivamile akubonakali. Ukusebenzisa le nqubo kukhulisa ematfuba uzingela nokuvimbela yokufa uhlangothi nokumelwa yinhliziyo.

Ngaphezu kwalokho, scan Helical liyadingeka kulezi zimo ezilandelayo:

• ukusungula izimbangela ikhanda, ukukhubazeka ngokuzumayo, gqwa pomrachneniya ukwazi ezihlukahlukene ongaboni ephula ukuzwela ezindaweni ezithile emzimbeni;
• uma kukhona izinsolo ukuthi unesimila ebuchosheni, yomthambo i-aorta useshonile ukudabuka, ukopha intracranial;
• ukusungula ukungasebenzi kwekhono zengaphakathi lendlebe esimweni kokuzwa ukungakhuli;
• uma ufuna ukuthuthukisa uhlelo ukusebenza nezikhulumi ukuhlola impumelelo ukusebenza kobuchopho;
• ukuhlonza izindawo ezilimele ingxenye yobuchopho.

Ngezinye izikhathi ingqondo luhlolo kudinga ejenti Ngokuphambene, okuyinto kusiza kakhulu ukuhlonza izinhlumba, zingcwecwe atherosclerotic, izimila, metastases, amahlule.

Ukuhlola ingaphakathi thoracic

Kuvunguza CT thorax kwenziwe ukuthola sofuba foci fistulas bronchopleural futhi bronchiectasis izimbotshana. Le nqubo ivumela ukuthola ngokunembile kakhulu isimila, igebe noma layering isitsha izindonga, ukukhomba kweNdikimba lymph node.

wasebenzisa ukuhlola okunjalo in Oncology ngempumelelo, ukunika amandla ukuba sihlole isimo umdlavuza, ukunquma kwemingcele yayo kanye nosayizi. Kwezinye izimo, tomography Helical kuboniswa ngenxa ukuthola izidumbu angaphandle, ngokuba kusungulwe umgudvu lobukene nalo i izimbangela iphika noma nobunzima ukugwinya.

isiphetho

Ngakho, Kuvunguza ngekhompyutha tomography iyindlela yesimanje of luhlolo kwezitho ahlukahlukene, okuvumela ukusungula ngokunembile uphethwe yini. Kushisa bhé kule ndawo umthamo kulolu cwaningo lincane kangangokuthi musa zibangele noma iyiphi umonakalo umuntu, ngakho ke ungesabi ka ukwenza inqubo enjalo.
