CT yemapapu kwenguva refu yakave imwe yezvidzidzo zvakakurumbira zvikuru. Zvose zvakakonzerwa nekururama uye kusuruvara. Tomography inokubvumira kuziva zvirwere zvakasiyana-siyana. Uyezve, inoita izvi kunyange pamatanho ekutanga, apo dzimwe nzira dzisiri dzekuongorora muviri hadzina simba.
Tini yemapapu?
Ichi chidzidzo che-x-ray. Asi kusiyana nechekare X-ray, computed tomography haisi inokuvadza. Kuzvipa, semurairo, kuitira kuti ujekese kana mumapapu uye nhengo dze mediastinum pave nekuve nekuchinja kupi. Izvi zvinoreva kuti nzira inofanira kuitwa mushure mekuita rayography kana fluorography uye chete kana zvikamu zvezvidzidzo zvinokonzera kushungurudzika.
Kazhinji CT inotumirwa pa:
- kuvapo kwemamwe mimwe mitumbi mubronchi;
- kunyunyuta kwekuvapo kwemakumbo akanaka kana akaipa;
- zvirwere zve sternum;
- kushungurudzika mubhagi ye pericardial;
- bronchiectasis zvirwere;
- kunyunyuta kwekuzvipira kwekugadzira kwemukatikati;
- kuchinja mumamiriro emapapu;
- kuvhiringidza mishonga mu lymph nodes mubhokisi;
- hutachiona hwe thymus gland.
Chii CT inoratidza?
Computer tomography inopiwa basa rekuona zvirwere zvepapupa zvakadai sekumborism isingaperi kana tuberculosis. Mukuwedzera, chidzidzo chinogadza kuvapo kwemamota uye kupisa kwemuviri mumuviri. Kakawanda, inorayirwa kune varwere vane mhosva dzinofungidzirwa dzehutano dzinokonzerwa ne inhalation yemakemikari.
Kuongorora kwemapapu CT kune ruzivo pamusoro pemamiriro emapfupa emapapu, pleura, bronchi, trachea, mishonga yemapurmita, yakanyanya vena cava, thoracic aorta. Kana chirwere chikawanikwa, tsanangudzo yakakwana yebundu uye kuparadzirwa kwayo inofanira kunge iripo pakuguma.
CT yemapapu zvakasiyana
Iyi nzira inowanzonzi angiography. Inowanzoitwa zvikuru mumamiriro ezvinhu apo kuvepo kwechirwere kunosimbiswa. Kudzidza nemashoko akasiyana-siyana kunopa data yakajeka pamusoro pekusava nechokuita chete, asiwo mamiriro emidziyo.
CT nechokusiyanisa chinotanga:
- kuvapo kwe atherosclerotic plaques ;
- aneurysms;
- pulmonary artery thromboembolism;
- pneumonia;
- tuberculosis ;
- nzvimbo dziri mumidziyo ine mhirizhonga;
- bronchial carcinoma.
Neyo pneumonia paC CT mumapapu, foci yekuputika kunooneka. Tomography yekuongororwa kwechirwere haisi kushandiswa nguva dzose. Iyo inorayirwa mune izvo zviitiko apo inowanzo X-ray kuongororwa kwemigumisiro yaidiwa haina kuonekwa.
Ko CT yemapapu?
Pamusana pekugadzirisa, shanduro yakashandiswa inoshandiswa, kunze kwayo yakafanana nekwakakura yakareba masvingo. Mukati, tafura inofamba inowirirana nayo. Chigadzirwa chacho chakabatana nekombiyuta uye inodzorwa nayo.
Nheyo yeCCT inotarisana nekuti maviri akasiyana mumuviri womunhu anotadza X-rays zvisina kufanira. Izvo zvinotyisa, zvinoparadzira chiedza, zvishoma kudete-zviitore. Pfungwa dzinoitika panguva imwe neimwe yezviitiko. Zviridzwa zvinogadzirisa, uye shure
Kangani kazhinji CT inogona kuitwa?
Nokuti iyo nzira inobatana zvakananga ne-ray ray-ray, kazhinji haigone kuitwa. Pamberi pekuongororwa, chiremba anofanira kudzidza kadhi yemurwere zvakadzama uye aone mutoro wewaini yaakagamuchira.
Kuita kombiyuta tomography, kunyange kana muganhu wekutsvaga wakapfuura, zvinodikanwa chete kana chiitiko icho chinogona kuchengetedza hupenyu, uye hapana imwe nzira inogona kuongororwa isingabatsiri panguva imwe chete.
Chimwe chinhu chakasiyana-siyana chekubuda kubva mumamiriro ezvinhu chinogonawo kuva nemhepo inonzi CT, iyo inonyanya kuderedza chiro chekugamuchira irradiation.
