MRI yobuchopho - ithuba lokuba bajonge ovela ngaphakathi

Magnetic intlokoma umfanekiso (okanye MRI) ebuchotsheni, amathambo kunye namanye amalungu njengendlela yophando esiqwini ithambo yi phambili ubhalo uviwo X-reyi kwaye ufaniso usebenzisa ikhompyutha. Kwiminyaka engaphezu kwekhulu eyadlulayo, uphando lwezonyango lubonisa ukuba kunokwenzeka ukukhangela ngaphakathi emzimbeni womntu, ukuba baxhamle iimpawu ebonakalayo umqadi X-ray. Ipropati lokuqala: kwi ngamaza umqadi mfutshane lencinibakazi ukukhanya. Okwesibini, umqadi X-ray uyakwazi zingene kwithishyu. ezintweni zayo kwintsunguzi simunce, ukubonakalisa ezithambileyo. Kwifoto ibonakala ngokucacileyo ekugqibeleni ke amathambo, amazinyo, esifubeni.

Itomography ngekhompyutha yaphuhliswa emva kokukhutshelwa yezonyango izixhobo zekhompyutha. Olu phando efana kakhulu-X-reyi. kuphela sigcinwa ezahlukeneyo nabenzi boluvo ababanikezelayo ikhokela X-ray kwi kwiindawo ezimbalwa ngaxeshanye, ngokungathi ekugawuleni ekujoliswe ilungu ibe ngamacetyana ezininzi. Le ndlela usinceda sibone isakhiwo lwangaphakathi wethambo kwicandelo kwaye ngokweenkcukacha. Yonke mifanekiso idluliselwe kwi computer, apho inokuba ngononophelo kwaye ukuphumla zula specialist.

Noko ke, njengokuba-x-reyi CT ezenza umntu abe imitha, yaye umntu omkhulu. Ngenxa yoko, oku kungabangela imizila emzimbeni kwaye kukhokelela kuphuhliso iiseli zomhlaza. neengxaki ezifana lwe-X-reyi khuthaza oogqirha kunye izazinzulu ukuba bafune iindlela ezikhuselekileyo yophando komzimba womntu. Ngoko ke, ngo-nzulu ukufunda imithetho yemvelo ukuphuhlisa iiteknoloji ezintsha ziye zakhokelela ukuvela ngo-1973 kukho indlela entsha.

Isiseko sele kungabekwa radiation X-reyi, kwaye iimpawu yamasimi Imagnethi yomhlaba kunye namaza erediyo. Bomfanekiso kwikhusi ngexesha MRI wobuchopho, kwakunye nezinye isicwili bone afunyenweyo ngenxa ngumongo atom hydrogen eyinxalenye wethambo phantsi kophando ubethwa radiation magnetic zobungakanani ezahlukeneyo. Walinganisa umlinganiselo wamandla obusuka undoqo njengoko ngokwaseburhulumenteni nemincili, yaye ngephanyazo zokuphumla. Lonke olu lwazi kufakwa kwikhompyutha, usebenzisa ubuchule zezibalo zilungiswa - nesisitheliso ibonisa umfanekiso echanileyo kakhulu lamanqanaba eziliqela ithambo, okanye naliphi na iqumrhu.

Esi sifo ivumela oogqirha ukuba uhlolisise ngokweenkcukacha uchonge isifo enyama yangaphakathi, leyo ezahlukeneyo awunakuvavanywa. Ekubeni kunzima kakhulu ukuba ukujonga ngaphakathi lukakayi, kukho indlela enye kuphela qiniseka ukuba ukuhlola kwizihlunu ezithambileyo ngaphakathi kwayo - yinto MRI ebuchotsheni. Phi kwaye njani ihamba?

Yintoni MRI kobuchopho? Le yinkqubo elula kakhulu umguli. Nje ukuya vuavanyisi - ngeskena elimxinwa nemishini. Ubuxoki kusekho imizuzu elishumi ukuya kumashumi amathathu. Ukulungiselela le njongo, ukuba iqhotyoshelwe iingalo, imilenze, esifubeni, kunye nentloko iibhanti ezizodwa ukunciphisa nokushukumisa umzimba. Ngokomthetho yabavavanyi abasakwazi emxinwa, oko kunokubangela uqeqeshwa. Maxa wambi, ezinye izigulane kubandakanya ngohlaselo ukwesaba ngexesha sifundo. Ngenxa yesi sizathu, sisungule i-MRI isithwebuli evulekileyo.

Yinto eyaziwa ngokubanzi ukuba intsimbi kunye nezinto ngegolide engathi ngumfanekiswana ziyivela kakhulu lo mhlaba otsalayo, ngoko ebudeni uhlolo izinto ezinjalo ukusuka isigulane kufuneka ibe phezu emzimbeni, kwaye kwigumbi kakhulu. Izacholo, amaqhosha, yaye benze imeyikhaphu kufuneka zisuswe phambi kovavanyo. Ngenxa yezizathu ezifanayo, MRI yobuchopho okanye nawuphi na umbutho awukwazi ukwenziwa kwabo izigulane kufuneka zitho, pacemakers okanye naziphi na ezinye implants yesinyithi.

Kwiminyaka yakutshanje, kuye ngokubanzi MRI ingqondo ne umahluko. Kakuhle eli ndlela kukuba isigulana kuthatha phambi kokuba arhente sifundo umahluko. Inika ithuba lokubona imeko iimpahla ezahlukeneyo lobuchopho negazi kwegazi nayiphi na imeko. Ezinye izigulane kunokuba uxabane ukuya into. Kwaye ukuba, mhlawumbi, kuphela umonakalo Akwaba bekukho umntu uhlobo kwesifo. Ngokubanzi, MRI isebenza kakhulu xa uzingela izifo, efihliweyo emva ithambo.
