Yintoni umahluko CT kunye MRI? Itomography Otherness

Xa kwakukho umatshini X-ray, kwaba impumelelo amayeza. Oku kwenza kube lula ukubona ukuphazamiseka yangaphakathi emzimbeni womntu, amalungu alo afumaneka yintoni imeko. Kodwa indlela omkhulu onjalo kuzisa ezithile neengxaki. Umzekelo, kwi-X-ray uyakwazi ukuthatha umfanekiso amanye amalungu, kodwa zilala phezu kunye nomfanekiso namanye amaziko.

Kwaye kulo mzekelo, uyakwazi ukubonakalisa okufihliweyo kwisiphumo ugqirha onamava kakhulu kunye nolwazi. Ngoko ke, ngenxa yezi olungabuy, inkqubela uye phambili.

iindlela ezintsha

Kule mihla, kukho ezinye iindlela zokufumanis enyama yangaphakathi, ezifana CT okanye MRI. Kodwa ke eli xesha kukho imibuzo emininzi. Ngokomzekelo, abanye uxilongo ukuba ukhethe yintoni umahluko CT kunye MRI? Ukongeza kweli nqaku, siza ukuchaza ngokweenkcukacha ahluke njani. Kwakhona ukuchaza ukuba isigulo ezifaneleke ngakumbi kwimeko ethile.

Siyaqonda ukuba umahluko CT kunye MRI

Ngoku, oogqirha abaninzi iingcebiso izigulane ukuba isifo ngcono ukuqhuba uhlolo ngokucokisekileyo ngakumbi, usebenzisa ikhompyutha okanye livakale magnetic ufaniso. Luhlobo luni uphando? Yintoni yahlukile CT MRI? Makhe sihlolisise:

• CT - a Itomography computer, esiqhutywa ngokusebenzisa impahla rentgenizlucheniya ngokwahlukileyo kwelifunekayo ubukhulu inyama ezahlukeneyo. Oko kukuthi, CT, ngokubanzi, efana i-X-ray, kodwa wafumana ngoncedo ulwazi kusetyenzwa ngendlela eyahlukileyo, kwaye sesichengeni sosasazeko lwemitha iphezulu kakhulu.

• MRI (Magnetic livakala iMifanekiso) kwenziwa kusetyenziswa emasimini ngemagnethi. athom hydrogen, ngenxa yefuthe layo, ukutshintsha indawo yabo, vuavanyisi sitsala le isiphumo kunye neenkqubo kumfanekiso-ntathu.

Njengoko ubona, umbuzo lowo - into yahlukile CT MRI, yintoni umahluko phakathi kwezi zixhobo ezimbini diagnostic - ngoko nangoko bafumana impendulo. Umahluko iphambili yobume ngamaza. In magnetic intlokoma umfanekiso - amaza. Xa ube nefuthe kwinyama omzimba ezahlukeneyo, enkosi oku, iindidi data olufundwa yi isixhobo kumatshini. Kwaye ngoko zonke iimpawu esenziwa kwaye, njengokuba loviwo CT, umfanekiso esweni sinikwe. Ngenxa kuye ugqirha ithuba ukubona izilayi nokuba sekhombuya ezithathwe kumaqumrhu. Ukongeza, umfanekiso kunokuba ijikelezwe kwaye, ukuba kuyimfuneko, ukwandisa indawo oyifunayo.

Yintoni kukho enye i umahluko phakathi CT ne MRI? Yintoni umfanekiso ongcono? uphethwe nganye yinto elungileyo kwaye ifundisa. Umahluko ephambili kuxhomekeke kuhlobo leengxaki kungabonwa zezi ndlela, yaye ukongezelela, ngoncedo reyi oku kwenziwe.

Umahluko ngexesha scan

Ukuthetha malunga umahluko CT kunye MRI, kubalulekile ukukhumbula ukuba Itomography ngekhompyutha (CT) kukho ukungakhuseleki radiation kakhulu, ngoko ke asikwazi zisetyenziswe rhoqo. Kodwa rentgenizluchenie luchaphazela amalungu angekho imizuzwana ngaphezulu kwe-10. Oku kuthetha ukuba uphando olunjalo kungcono kwenziwa nabantu abaphethwe bephelelwa umoya.

Magnetic intlokoma umfanekiso yi (MRI) idla ithatha imizuzu elishumi okanye ngaphezulu, kuxhomekeka kwindawo leyo yophando. Ngoko ke kufuneka ukuba aqhube nangoku. Ngoko ke, MRI sifaneleke ngakumbi abo bangenazo ezinxaxhileyo kakhulu psyche. Njengoko ngenxa yoonyana, esebenzisa iinkcukacha ngemagnethi livakale umfanekiso, basuke anesthetized.

Ngokusekelwe ngasentla, siyaqonda njani umahluko phakathi MR ukuba CT. Yintoni ngcono MRI okanye CT scan kuwe? Lo mbuzo iphendulwe gqirha kuphela, ngokusekelwe iimpawu zomzimba wakho.

Xa usebenzisa MRI?

Kaloku iziyatha abaphethwe zizifo ezahlukahlukeneyo, ubhekisela ugqirha, cela ngoko yahlukile CT MRI. Kodwa ekubeni sele ufumene impendulo kuyo, ke qhubeka ukuthetha, oko izifo kubhetele ukusebenzisa MRI, nalapho - CT.

MRI inika ulwazi olugqityiweyo kunikwe ekufundeni kwizihlunu ezithambileyo. Ngoko ke, oko kumiselwe kwezi meko zilandelayo:

• ukuba umntu imfundo inwebu kwezihlunu, iiseli elityetyisiweyo esisu kunye isinqe (oku kwenzelwa ukufumana umfanekiso opheleleyo emva isifundo usebenzisa ultrasound);
• yezifo ezahlukeneyo ingqondo kunye umnqonqo;
• xa kukho urhano lokuba ubuchopho okanye indawo umnqonqo kukho ukuphazamiseka ukuhamba kwegazi;
• xa ufuna ukuhlola loo IiCD intervertebral okanye imeko emzimbeni ezidibeneyo.

Kwaye xa kusetyenziswa ngekhompyutha Itomography? It emiselweyo:

• ukuba isifundo esiqwini wethambo kummandla yomqolo kunye namalungu;
• xa ithambo lichatshazelwe iimanyano ithumba;
• xa amathambo amathambo bayo trauma;
• ezimbi e esiswini, zangasese, nemiphunga;
• utshintsho atherosclerotic kule olujikeleza.

Izimo

Ucingisisa ngoko kuye kuchazwe ngasentla, ugqirha uya kukwazi ukukhetha uhlobo lasekunene ukuxilongwa isigulane ngamnye. Kodwa kukho ezinye Izimo, apho kufanele kuqwalaselwe.

Ezi ziquka oku kulandelayo:

1. CT ayivumelekanga ngexesha lokukhulelwa.
2. MRI akukho kuboniswe:

• phambi kukhona kwaye ingenisa umzimba;
• xa ekhona ancedisana yamacebo ngekhompyutha (umz ipacemaker);
• abaphethwe bephelelwa;
• umntu ezinobunzima-150 kg;
• izigulane zizigulo zemithambo ngubani na ihlale ixesha elide endaweni enye.

Ekugqibeleni, encinane

Umbuzo oko ngcono iisaveyi ezimbini lokukhetha, cela umntu ngamnye uya unesifo amalungu zangaphakathi. Kwaye ukuze kakubi impilo yabo, ukufumana ingcaciso eninzi luncedo, isigulana ugqirha wakho kufuneka sibuze, yintoni umahluko CT kunye MRI. Kunye neengcali ukunceda ukuqinisekisa ukuba isigulana efanelekileyo ngakumbi kwimeko nganye.
