Overview

Lissafta tomography (CT) duba - wani zamani rabe nazari na jikin mutum. Yana dogara ne a kan kwamfuta aunawa da kuma sarrafa bambanci a attenuation na X-radiation yadudduka, daban-daban a cikin su yawa. Amfani lissafta Tomography bincikar jikin gani daga kusurwoyi mabambanta, saboda haka yana yiwuwa a samu wani image a duk tsinkaya da uku-girma form.

Domin gudanar da CT yana amfani da wani musamman X-ray CT na'urar daukar hotan takardu. Yana hada da wani m tebur, shigar da mãsu haƙuri a cikin wuyan da scanning naúrar, a cikinsa na'urori masu auna sigina ne radiation da X-ray tube.

Sai suka tafi, ta hanyar kwamfuta da aiki, sakamakon abin da za a iya gani a kan allo. A samu image nazarin da na nazarin radiologist, sa'an nan ya rubuta zuwa rikodi matsakaici da kuma kwafi su a kan tef. A duka bincike aiwatar daukan ba fiye da minti 10, amma dangane da na'urar daukar hotan takardu da kuma takamaiman kamu zone ake bukata da kuma har zuwa rabin awa.

Shawarwari kafin da kuma bayan da gwajin

Marasa lafiya da suka samu a CT scan, so in sani: Mene ne wani CT scan, wanda shawarwari da ya kamata a lura kafin hanya, a lokacin da kuma bayan shi. Domin duk iri duba shi ne shawarar for 2 hours kafin zuwa binciken to ki abinci da abin sha. Ga ganewar asali na wani gabobin, da kuma a wasu lokuta da wani likita yanke shawara bukatar igiyar jini bambanci wakili don inganta sakamakon da binciken. Wannan zai faɗakar da kowane haƙuri halartar likita ko ma'aikacin lafiya CT ofishin.

Yana da muhimmanci a san cewa idan haƙuri yana da lantarki, inji kuma Magnetic implants (prostheses, karfe faranti, auna bugun zuciya), wata rana kafin CT sun nazarin yin amfani da barium dakatar, kazalika a lokacin daukar ciki shi wajibi ne in sanar da likita.

A binciken da na jiki ya zama free of tufafi da kuma kayan ado. A lokacin jarrabawa na AMINCI da sakamakon kana bukatar ka kwanta har yanzu, za ka iya bukatar numfashin-Holding ga 'yan seconds. Lissafta tomography - cikakken m gwajin.

Mene ne alamomi ga yin amfani da CT?

Lissafta tomography aka yi amfani da routinely, gaggawa, kiwon lafiya da kuma bincike hanyoyin, kamar monitoring na huda.

A matsayin nunawa gwajin wajibi ne don yin CT tare da m ciwon kai, musamman tare da amai, lokaci-lokaci asarar sani ko seizures, shugaban raunin, kazalika da ware oncological hali na ilimi.

A wani binciken da za'ayi gaggawa a tsanani raunuka, da ake zargi da rai barazana lalacewar gabobin, jini, da ganewar asali daga kwakwalwa haemorrhage.

Lokacin da yi CT na ciki?

Ciki lissafta tomography sarari amfani ga m ganewar asali ga cututtuka baƙin ciki, gallbladder, hanta, pancreas, ciki, da lstogo hanji.

CT ciki ne kullum da za'ayi tare da intravenously gudanar da bambanci wakili, tun da taushi nama gabobin suna da wuyar gane asali. Bambanci da ciwon dukiya unequally tara a daban-daban kyallen takarda, gabobin sa ya yiwu a rarrabe daga juna, wanda ni'ima daidai ganewar asali.

A bayyanar cututtuka ga wanda likitoci bayar da shawarar da suke ciyarwa ciki CT: m zafi a cikin ciki yanki, yellowing na fata da kuma sclera, anemia, ban mamaki nauyi asara, da samuwar wani m yanayi, gano ta hanyar duban dan tayi.

Lokacin da kashin baya ne da za'ayi kwamfuta tomography?

Wannan binciken da aka yi amfani da ko'ina ga ganewar asali na nono cuta, mahaifa da lumbar kashin baya. Yana samar da wata dama ga tantance biyu da tsarin kasũsuwa, ashe, jini da kuma taushi da nama da kuma samun uku-girma image.

CT na kashin baya ne da za'ayi a cikin wadannan lokuta:

• ƙari metastasis ko na dab gabobin.

Ya kamata ka sani cewa, ko da bayan qananan farko duba a cikin kashin baya rauni, kazalika da wani ciwon baya haskakawa cikin daya daga cikin ƙananan wata gabar jiki, dole ne ka shawarci likita nan da nan. Kawai likita bayan jarrabawa na haƙuri iya yanke shawara a kan bukatar lissafta tomography.

Mene ne alamomi na lissafta tomography daga cikin kirji?

CT na'urar daukar hotan takardu da aka samu nasarar amfani ga ganewar asali na cututtuka na zuciya da jijiyoyin jini tsarin, kasusuwa da kuma thoracic hakarkarinsa tantance huhu yanayin. A kirji CT scan wajibi ne a cikin ganewar asali:

Tare da shafe tsawon tari, sweating, kwatsam nauyi asara, janar wani rauni, kazalika da bayyanar unexplained canje-canje a kan kirjin radiograph wajibi ne a ko da yaushe tuntubar likita domin a yanke shawara a kan CT a kirji. Wannan binciken da za su taimaka wajen kawar da huhu marurai, su kullum cutar, da tarin fuka.

Abin da bincike ne mafi alhẽri ga CT ko MRI?

Yau, duka biyu bincike Hanyar da aka samu nasarar amfani ga daidai ganewar asali da yawa cututtuka. Don gane da abin da irin binciken da ya kamata, kana bukatar ka sani a general sharuddan abin da yake CT, yadda shi ya bambanta daga MRI. Duka hanyoyin da abu daya a cikin kowa - da amfani da hanyar na hanyõyi scanning na jikin mutum. In ba haka ba, su ne quite daban-daban kuma ba su da kowa halaye bisa manufa.

Tare da MRI ka iya fahimtar matsayi na wadannan tsokoki: guringuntsi, jijiyoyi, tsokoki da kuma jijiyoyin, don haka wannan hanya yana da muhimmanci musamman a neurosurgery.
