Enye yezindlela zesimanje, ezifundisa futhi eziphumelelayo zokuhlola i-X-ray yesimiso sezinzwa zomuntu zibalwa ngobuningi be-tomography noma i-CT yobuchopho. Le nqubo ikuvumela ukuba uthole isithombe se-organ emininingwaneni emininingwana, eyenza lula ukuxilongwa nokuphathwa kokwelashwa.
I-CT yobuchopho kanjani?
Okuyinhloko yale nqubo ukwenza izithombe ze-X-ray zobuchopho ezingxenyeni ezihlukene besebenzisa i-boram directional of radiation. Ubukhulu bendlala eyodwa, njengombuso, kusuka ku-0.5 kuya ku-1 mm, okuqinisekisa ukucacisa okuphakeme kakhulu kwesithombe esakhiwe kabusha. Ngamazwi alula, isithombe sokugcina siqoqwa kusuka kusethi yezici ezilandelanayo, njengesinkwa sezinkwa - kusuka ezincekeni ezincane ezicucwe.
Ukuhlolwa kobuchopho nge-CT:
- Isiguli sisusa noma yiziphi izinto zensimbi nezingubo ezivela ekhanda nasemqaleni.
- Isiguli sigxilwe endaweni enezingqimba, ohlangothini ngalunye lapho kutholakala khona umthombo kanye nesamukeli sama-X-ray (ngendlela yombuthano).
- Inhloko ifakwa kumnikazi okhethekile ukuqinisekisa ukusimama kwayo.
- Ngaphakathi kwemizuzu engu-15-30 uchungechunge lwezithombe ze-X-ray lwenziwa ngamaphuzu ahlukene.
- Izithombe ezitholiwe zitholwa kumqapha wekhompiyutha wezokwelapha, okuyinto eyanciphisa ngokusebenzisa uhlelo olukhethekile.
Kubalulekile ukuqaphela ukuthi ngesikhathi sesifundo isiguli singabona konke okwenzekayo, ngakho-ke i-CT iyindlela elula yokuxilongwa ngisho nabantu abahlukunyezwa yi-claustrophobia. Ngaphezu kwalokho, umsizi we-laboratory uhlola isimo sesiguli njalo ngomzuzu futhi, uma kunesidingo, angakwazi ukuxhumana naye.
I-CT yobuchopho nge-perfusion noma ngokuphambene
I-Perfusion ikhompyutha ye-tomography isetshenziselwa ukuxilongwa okunembile kwezifo zesimiso se-vascular of tissue tissues.
Le nqubo ifana ne-CT evamile, kodwa kusengaphambili, i-100 kuya ku-150 ml ye-medium medium ijojowe emzimbeni wesiguli. Isixazululo sinikezwa nge-syringe okuzenzekelayo noma i-dropper.
Kulokhu, ukulungiswa okunye kwe-CT yobuchopho kuyadingeka - awukwazi ukudla amahora 2.5-3 ngaphambi kokuqala kocwaningo.
Nge-tomography nge-perfusion, iziguli eziningi zithola umuzwa wokushisa kuwo wonke umzimba, ikakhulukazi ngokushesha ngemva kokujova, futhi ukunambitheka kwe-metallic kuvela olimini. Lezi zenzakalo ezijwayelekile ezizophela zodwa emaminithini ambalwa.
Izinkomba ze-CT zobuchopho
Indlela echazwe ngayo yokuxilongwa ifaka isicelo sokusola ngezifo ezinjalo:
- izinkinga ngemuva kokulimala komshini ebuchosheni;
- ikhanda elinamandla elingenakuthola ukuphathwa kwezidakamizwa;
- ukuphazanyiswa emsebenzini wezingxenye zokuzwa, ukubona, inkulumo;
- ukuzondwa nokuphilisa okuqhubekayo;
- ingxabano ebuchosheni ;
- izicubu ezingxenyeni zobuchopho;
- i-abscess, i-edema ye-cerebral;
- i-atherosclerosis ;
- isifo esibuhlungu, isisindo somswakama;
- ukungena;
- ismmus of the brain rhomboid;
- aneurysm;
- i-neuroinfection.
Lolu cwaningo lwenziwa ukuze kuqashwe ukusebenza kahle nokulungiswa okulandelayo kwendlela yokwelapha ye-encephalitis, umdlavuza, kanye ne-toxoplasmosis.
Ukuqhathaniswa kwe-CT yobuchopho
Awukwazi ukusebenzisa lolu hlobo lwenhlolovo ezimweni ezinjalo:
- ukungahambisani nemithi eline-iodine;
- ukungafinyeleleki okweqile noma okweqhwaba;
- ukukhulelwa;
- izigaba ezinzima zesifo sikashukela mellitus;
- isisindo sesiguli ngaphezu kuka 130 kg;
- ukutholakala kwemizimba yangaphandle ekhanda;
- ngaphambilini wathola amanani aphezulu we-X-ray.
