Ukuchonga utshintsho oluthile kumsebenzi wezitho zomntu ezahlukeneyo kunye neenkqubo, akusoloko kusanele ukupasa iimvavanyo. Ngamanye amaxesha kuyimfuneko ukuqhuba ezinye izifundo. Ejongene nesidingo sokhetho, izigulane ezininzi zinoyika kakhulu ukwenza iimpazamo, kuba abazi into engcono kunokuba i-tomography okanye i-MRI ibhaliweyo.
Uthini umahluko phakathi kweMRI kunye ne-tomography?
Ukuqonda ukuba yiyiphi inzululwazi enolwazi ngakumbi kwimeko yakho, kufuneka uqonde umehluko phakathi kweMRI kunye ne-tomography. Umehluko omkhulu phakathi kwale nkqubo yimiba eyahlukeneyo eyenziwa kwizixhobo zokusebenza. Ngomfanekiso we-tomography, lo ngu-ray-ray. Inika umfanekiso opheleleyo wesimo somzimba kunye neenkqubo. Ngomfanekiso wokuhlaziya emagnini, yisoloko ishukumisa intsimi kunye ne-radiation-frequency radiation. "Batsho" malunga nesakheko samakhemikhali.
Umahluko phakathi kwe-MRI kunye ne-tomography ekhompyuthile kukuba ngethuba le-CT udokotela angakwazi ukubona zonke iiscuphe kwaye afunde i-X-ray yobunzima, obuhlala buguquka ngexesha lokugula. Ngokuhlukileyo ekubunjweni, izicubu zithatha ngokupheleleyo imida yecebo ngeendlela ezahlukeneyo. Yingakho, umncinci umehluko kumandla okuxhamla, ngokucacileyo kucace umfanekiso uya kuba ekupheleni. Nge-MRI, unokuhlola kuphela umfanekiso, kuba isekelwe kwi-tissue ehlukeneyo nge-hydrogen. Oku kukuvumela ukuba ubone ngokucacileyo izihlunu, izicubu ezithambileyo, iigaments, intambo yomgudu kunye nokuba ingqondo. Kodwa ngelo xesha, amathambo ayabonakali, kuba uphando olunjalo alukho i-resonance ephuma kwi-calcium.
Ukwahlukana kukukhulu kwendawo ehlolwayo kunye ne-MRI kunye ne-tomography. Xa ukwenza i-CT, awukwazi ukuskena umqolo wonke, kuphela inxalenye encinci iya kubonakala. I-device ye-MRI inokufihla nayiphi na inxalenye yomzimba ngokupheleleyo.
Kulunge nini ukwenza iMRI?
Uyazi umahluko phakathi kovavanyo lokuxilonga, kodwa awuqondi ukuba yintoni i-tomography echanekileyo ngakumbi kunekhompyutha okanye i-MRI kwimeko yakho? Inkqubo ye-MRI isoloko ikwazisa ngakumbi xa:
- Multiple sclerosis ;
- izicubu zeengqondo;
- ukubetha;
- ukuvuvukala kweethambo zomzimba;
- izifo ezithinta iingxube ezihlanganyelweyo, izicubu ze-muscle kunye nezixhobo zeligament.
Ukuxilongwa kwesi sifo kunye ne-MRI kuyimfuneko nakwiimeko xa isigulane singenakubekezelelana kwizinto eziphathekayo kwi-radiopaque, kuba kwezinye iimeko, i-CT iboniswe ngokulawulwa kwayo.
Ukucinga nge-magnetic resonance iyona nto ikhethekileyo xa kukho imfuneko yokufunda iingxaki ze-intracranial, i-pituitary gland kunye nomxholo we-orbital. Kwakhona, isifundo esinjalo sifanele senziwe ngabo bafuna ukwazi isigaba somhlaza kunye nokuqaliswa okugunyazisiweyo kwe-ejenti eyahlukileyo (umzekelo, uGadiolinia).
Kulunge nini ukwenza CT?
Ukufumanisa ukuba yintoni umehluko phakathi kwe-MRI kunye ne-tomography ekhompyutheni, izigulane ezininzi aziqondi ukungafani kwezi zifundo kwaye zikholelwa ukuba zifana ngokufanayo. Uninzi lwabantu lukhetha i-CT kuba le nkqubo ithatha ixesha elingaphantsi kunye neendleko ezingaphantsi. I-tomography yekhompyutheni ifanelekile ukuyenza xa wena:
- ukuxhwaleka kwintliziyo yengqondo okanye ithambo;
- i-hematomas acatraal acute;
- izicubu zeengqondo;
- ukutshatyalaliswa kwezono ze-paranasal, i-facial squelet, i-jaws, i-thyroid gland;
- ukuphazamiseka kwemisipha ye-cerebral;
- otitis okanye sinusitis .
Ngaba unokukhetha - CT okanye iMRI? Khetha owokuqala ukuba unaso naziphi na ukusola ngazo nasiphi na isifo somgudu (i-hernia discs, i-osteoporosis, i-scoliosis, njl.). Olunye ulwazi luyi-CT yomdlavuza wamaphaphu, isifo sofuba kunye ne-pneumonia. Kukhethwa ukufumana isifundo esinjalo kunye nabo bafuna ukucacisa i-radiographs yesifuba.
