Ukuthola izinguquko ze-pathological emsebenzini wezinhlaka ezihlukahlukene zomuntu nezinhlelo, akusilo ngokwanele ukudlula izivivinyo. Ngezinye izikhathi kubalulekile ukuqhuba ezinye izifundo. Ebhekene nesidingo sokukhetha, iziguli eziningi ziyesaba ukwenza amaphutha, ngoba azi ukuthi yini engcono kune-tomography noma iMRI.
Uyini umehluko phakathi kwe-MRI kanye ne-tomography ehlanganisiwe?
Ukuze uqonde ukuthi yikuphi ukuhlola okunye okufundisayo kulesi simo, udinga ukuqonda umehluko phakathi kwe-MRI ne-tomography ehlanganisiwe. Umehluko omkhulu phakathi kwale nqubo yizimo ezihlukahlukene zomzimba ezisetshenziselwa izixhobo. Ngomfanekiso we-tomography, lokhu kuyi-ray ray ye-X. Inikeza umfanekiso ophelele wesimo sangempela sezitho nezinhlelo. Ngomfanekiso we-resonance magnetic, kuyisimo se-magnetic njalo nomsakazo we-radio frequency. "Batshela" mayelana nesakhiwo samakhemikhali.
Umehluko phakathi kwe-MRI kanye ne-tomography ehlanganisiwe ukuthi phakathi no-CT udokotela angabona zonke izicubu futhi afunde ubuxhakaxhaka babo be-X-ray, ehlala ishintsha ngesikhathi sokugula. Ehlukile ekubunjweni, izicubu zithinta ngokuphelele imisebe yedivaysi ngezindlela ezahlukene. Yingakho-ke, umahluko omncane ekumeni amandla, kancane ukucaca isithombe kuzobe sekupheleni. Nge-MRI, ungahlola kuphela isithombe, ngoba sisekelwe ekufakweni kwezicubu ezahlukene nge-hydrogen. Lokhu kukuvumela ukuba ubone ngokucacile imisipha, izicubu ezithambile, izigulane, intambo yomgogodla ngisho nobuchopho. Kodwa ngesikhathi esifanayo, amathambo ayabonakali, ngoba ngokuhlola okunjalo akukho i-resonance esuka ku-calcium.
Umehluko usayizibukhulu bendawo ehlolwe ngayo nge-MRI kanye ne-tomography ehlanganisiwe. Uma wenza i-CT, awukwazi ukuskena lonke umgogodla, ingxenye eyodwa nje kuphela izobonakala. Idivayisi ye-MRI ingakwazi ukumboza noma iyiphi ingxenye yomzimba ngokuphelele.
Kungcono nini ukwenza i-MRI?
Uyazi umehluko phakathi kwezifundo zokuxilonga, kodwa awuqondi ukuthi i-tomography inembile kangakanani kunekhompyutha noma i-MRI kuwe? Inqubo ye-MRI ihlale ifundisa kakhulu uma:
- I-multiple sclerosis ;
- izicubu zobuchopho;
- ukushaywa;
- ukuvuvukala kwezicubu zobuchopho;
- izifo ezithinta izakhiwo ezihlangene, izicubu zamascle kanye namadivaysi e-ligamentous.
Ukuxilongwa kwesifo nge-MRI kuyadingeka nasezigabeni lapho isiguli singahambisani nokusetshenziswa kwe-radiopaque, ngoba kwezinye izimo, i-CT iboniswe ngokuphathwa kwayo.
I-imagination resonance magnetic iyona engcono kakhulu uma kudingekile ukutadisha izinzwa ezingasebenzi, i-pituitary gland nokuqukethwe kwe-orbital. Futhi, isifundo esinjalo kufanele senziwe yilabo abadinga ukwazi isigaba somdlavuza ngesingeniso sokugunyazwa kwe-agent ehlukile (isibonelo, i-Gadolinia).
Kungcono nini ukwenza CT?
Ukuthola ukuthi umehluko ophakathi kwe-MRI ne-tomography ehlanganisiwe, iziguli eziningi aziqondi umehluko omkhulu walezi zifundo futhi bakholelwa ukuthi zifana ngokufanayo. Iningi labantu likhetha i-CT ngoba le nqubo ithatha isikhathi esincane futhi izindleko zingaphansi. I-tomography yekhompyutha ibalulekile ngempela ukwenza uma:
- ukuhlukumezeka emathanjeni obuchopho noma ekhanda;
- ama-hematomas acatrical acracteral;
- izicubu zobuchopho;
- ukunqotshwa kwezono ze-paranasal, isifuba sobuso, izinhlanzi, ugqozi we-thyroid;
- ukuphazamiseka kokusakaza kwe-cerebral;
- i-otitis noma i- sinusitis .
Ingabe unesinqumo - CT noma i-MRI? Khetha owokuqala uma unezinsolo zesifo esithile somgogodla (i-hernia discs, i-osteoporosis, i-scoliosis, njll). Okunye okufundiswa yi-CT emdlalweni wamaphaphu, isifo sofuba kanye ne-pneumonia. Kungcono ukuqhutshwa isifundo esinjalo nalabo abadinga ukucacisa ama-radiographs esifubeni.
