I-Magnetic resonance imaging (MRI), eyaziwa nangokuthi i-nuclear magnetic resonance imaging (NMR), ukuhlolwa kwesithombe okwazi ukukhombisa ukwakheka kwangaphakathi kwezitho ezinencazelo, kubalulekile ukuthola izinkinga ezahlukahlukene zezempilo, ezinjenge-aneurysms, tumors, changes amalunga noma okunye ukulimala ezithweni zangaphakathi.

Ukwenza ukuhlolwa, kusetshenziswa umshini omkhulu, odala izithombe ezinencazelo ephezulu yezitho zangaphakathi ngokusebenzisa amandla kazibuthe, okwenza ukuthi ama-molecule omzimba aphazamiseke, athathwe yidivayisi futhi adluliselwe kukhompyutha. Ukuhlolwa kuhlala cishe imizuzu eyi-15 kuye kwengama-30 futhi, imvamisa, akukho ukulungiselela okudingekayo, noma kungadingeka ukusebenzisa umehluko, kwezinye izimo, ngomjovo womuthi ngomthambo.

Umshini we-MRI

Isithombe se-Magnetic resonance sogebhezi

Yenzelwe ini

Ukucabanga kwe-Magnetic resonance kuboniswe ezimweni ezilandelayo:

• Khomba izifo zemizwa, njenge-Alzheimer's, isimila sobuchopho, i-multiple sclerosis noma isifo sohlangothi, isibonelo;
• Bheka ukuvuvukala noma izifo ebuchosheni, izinzwa noma amalunga;
• Thola ukulimala kwemisipha, njenge-tendonitis, ukulimala kwe-ligament, ama-cysts, njenge-cyst kaTarlov noma ama-discs we-herniated, isibonelo;
• Khomba uquqaba noma izicubu ezithweni zomzimba;
• Bheka izinguquko emithanjeni yegazi, njenge-aneurysms noma amahlule.

Kuyadingeka ukuthatha izinyathelo ezithile ngaphambi kokwenza lokhu kuhlolwa, ngoba ngeke kube khona noma yiluphi uhlobo lwezinto ezisansimbi eziseduze nensimu kazibuthe yedivayisi, njengezikhonkwane zezinwele, izingilazi noma imininingwane yezingubo, ngaleyo ndlela kugwenywe izingozi. Ngalesi sizathu esifanayo, lolu vivinyo luyaphikiswa kubantu abananoma yiluphi uhlobo lokufakelwa, ama-pacemaker noma izikhonkwane zensimbi ezifakwe emzimbeni.

Ngaphezu kwekhwalithi enhle yezithombe ezakhiwe ngemifanekiso yamagnetic resonance, enye inzuzo ukungasetshenziswa kwemisebe ye-ionizing ukuthola imiphumela, ngokuhlukile kune-computed tomography. Qonda ukuthi yenzelwe ini futhi lapho kudingeka i-CT scan.

Kwenziwa kanjani

Ukucabanga ngemagnificent resonance kuvame ukuhlala phakathi kwemizuzu eyi-15 kuye kwengama-30, futhi kungadlulela emahoreni ama-2 kuya ngendawo ezohlolwa. Ngalokhu, kuyadingeka ukuthi uhlale ngaphakathi kwensimbi ekhipha amandla kazibuthe, futhi ayilimazi, noma kunjalo, kubaluleke kakhulu ukunganyakazi ngalesi sikhathi, ngoba noma yikuphi ukunyakaza kungashintsha ikhwalithi yezivivinyo.

Kubantu abangakwazi ukuma bame, njengezingane, abantu abane-claustrophobia, i-dementia noma i-schizophrenia, ngokwesibonelo, kungadingeka ukwenza isivivinyo nge-sedation ukuze balale, uma kungenjalo ukuhlolwa kungahle kungasebenzi.

Ngaphezu kwalokho, kwezinye izimo, kungahle kudingeke ukuthi kufakwe umehluko emthanjeni wesiguli, njengeGallium, njengoba kuyindlela yokudala incazelo enkulu yezithombe, ikakhulukazi ukubona ngeso lengqondo izitho noma imithambo yegazi.

Izinhlobo ze-MRI

Izinhlobo zama-MRIs zincike kusayithi elithintekile, okuvame kakhulu okubandakanya:

• Ukucabanga ngemagnificent resonance kwe-pelvis, isisu noma isifuba: isebenza ukuhlonza izimila noma izixuku ezithweni ezifana nesibeletho, amathumbu, amaqanda, iprostate, isinye, amanyikwe, noma inhliziyo, isibonelo;
• Ukucabanga kwemagnetic resonance kogebhezi: isiza ukuhlola ukukhubazeka kobuchopho, ukopha kwangaphakathi, i-cerebral thrombosis, izicubu zobuchopho nezinye izinguquko noma ukutheleleka ebuchosheni noma ezitsheni zayo;
• I-Spine MRI: kusiza ukuxilonga izinkinga emgogodleni nasentanjeni yomgogodla, njengezicubu, ukubalwa, i-hernias noma izingcezu zamathambo, ngemuva kokuphuka - Bona ukuthi ungayibona kanjani i-arthrosis emgogodleni, isibonelo;
• I-MRI yamalunga, njengehlombe, idolo noma iqakala: isebenza ukuhlola izicubu ezithambile ngaphakathi kwejoyini, njenge-bursa, tendon and ligaments.

Ukucabanga kwamagnetic resonance, ngakho-ke, ukuhlolwa okuhle kakhulu ukubona izingxenye ezithambile zomzimba, noma kunjalo, akuvamisile ukukhonjiswa ukubona izilonda ezifundeni eziqinile, njengamathambo, lapho, kulezi zimo, izivivinyo ezifana ne-x-ray noma i-computed tomography ikhonjiswe kakhulu., isibonelo.
