Kanjani MRI izinso? izinso MRI kanye ngomgudu womchamo: izici zokuxilonga

MRI we nezinso kuyinqubo ephezulu ukucacisa, esiqhutshwa ngosizo uphethwe kwezitho besisu, okuvumela ukusungula okuyikona, kanye sokunquma pathogenesis asathuthuka egunjini lokuhlolwa kwezifo. Le ndlela isekelwe kazibuthe, lapho inqubo kobuhlungu futhi iphephile. Nikeza nganoma ahlukahlukene esolwa isifo so-renal kanye uhlelo urogenital. Ngakho kwenziwa kanjani MRI we nezinso, elibonisa isifundo esinjalo? Ake sizame ukuqonda lokhu.

Kuyini MRI?

Magnetic resonance imaging, okungukufa ulwazi kakhulu, ihlinzeka eliphezulu isithombe ngakuthathu, ngakho wafaka le uphethwe ngqo. Ukuze MRI we nezinso ngomgudu womchamo kuyinto ubuncane contra-izinkomba. Inqubo iphephile, futhi akungenxa walungisa ngokukhethekile, isibonelo, US. Futhi izinso MRI kahle ikubekezelele iziguli ngenxa yokuthi ukuthi uhlelo lwayo lokusebenza akuyona ukusetshenziswa ionizing emisebeni e.

Le nqubo wenziwa ngezindlela ezimbili:

• ihluke - kulokhu ukujovwa nge isixazululo equkethe iodine ekuthuthukiseni izifundo ulwazi;
• ngaphandle Ngokuphambene - isetshenziswa uma kukhona yokungezwani komzimba ukuze ikhambi.

izinkomba ngoba

MRI we nezinso kuboniswa ngenxa isidingo ukusungula uphethwe futhi ukuhlola ngezimo zesiguli phambi enquma ukwelashwa.

I izinkomba ezilandelayo kulolu cwaningo:

• ubuhlungu chronic esifundeni lumbar, asinikeze ukhalo, ezinqulwini nge omsakazo engaqinisekile;
• ukuvuvukala okunzima ebusweni futhi emikhawulweni;
• imiphumela abampofu lokhu kuhlolwa umchamo;
• Ukugodola kwenja futhi umkhuhlane;
• osenyameni olunegazi umchamo;
• ubuthakathaka, ukukhathala kanye ukucobeka isizinda colic ephansi emuva;
• ubuhlungu ukuchama noma ukuphazanyiswa yale nqubo.

Esikuvumela bheka MRI?

Iziguli eziningi unesithakazelo ukuqokwa MRI we nezinso Yini le ucwaningo lubonisa enqubeni wekuhlolisisa kusebenta kwahulumende? Ngenxa nomthelela emzimbeni kazibuthe, kungenzeka ahlolisise imizimba eminingi eziyize okuyinto zitholakala esifundeni lumbar.

Ngakho, i-magnetic resonance imaging ikuvumela ukuba ubone:

• isimo izinso: khona amatshe, isihlabathi, umthamo wabo excretory;
• isakhiwo umzimba: lingakanani, izici morphological kwezicubu, izinqubo sokugembula eminyangweni;
• isimo imithambo yegazi, futhi patency wesistimu urinary;
• izinqubo ukuvuvukala noma esiwohlozayo isinye;
• khona izimila ingozi futhi ebulalayo metastases;
• izifo ezithathelwanayo ezibangelwa amagciwane kwesinye kanye nezinye izitho.

Emihle nemibi MRI

Ukutadisha okunjalo we komgodi ongaphakathi kwamathumbu has izinzuzo ezilandelayo: ephephile, ngaphandle kobuhlungu, iningi ulwazi, angakwazi ukuhlonza inqwaba izifo kusaqalwa yentuthuko. Onjalo okusezingeni eliphezulu ngokunemba uphethwe ayinakho X-ray kanye nezinye izindlela zesimanje zophenyo.

MRI we nezinso akubangi umonakalo empilweni lesiguli futhi akabubangeli ukuxakeka. Nokho, kukhona ukulinganiselwa ezithile ngoba ukudlula ukwenza inqubo enjalo. Lezi zihlanganisa:

• ukwehluleka kwezinso;
• ukuphendula iguliswa Ngokuphambene injected;
• khona e lesiguli umzimba wensimbi izimila, elawula ukushaya kwenhliziyo, shards, ukudla;
• ukugula ngengqondo, claustrophobia;
• sokukhulelwa, ikakhulukazi senyanga yokuqala;
• ngokweqile isisindo isiguli (angaphezu kuka-120 kg);
• Uma inqubo uya umdlezane ke ngemva kwalokho awukwazi ukondla umntwana ubisi izinsuku ezimbili.

Ephambi kwezinduna izimo esinjalo isiguli kufanele azise udokotela yabo nochwepheshe oqhuba inqubo.

Izici cwaningo

Awudingi ukuba uzilungiselele ngandlela-thile ikakhulu phambi othola luhlolo. Ungathatha ukudla, uketshezi, imithi ehlukahlukene. Okuwukuphela ngaphandle - a MRI izinso kanye umehluko. Kulokhu, awukwazi ukusebenzisa izidakamizwa ezinamandla.

Ngaphambi cwaningo, isiguli kumele asuse zonke izinto eziyinsimbi (amasongo, amawashi, namacici, nokunye. D.). Khona-ke umuntu ulala phansi phezu mobile kusofa, futhi iqinile nge ukuwuthukulula. Phakathi nale nqubo, isiguli kufanele kube umile. Lokhu kuphumela high quality izithombe.

Isiguli is egxilile umzimba imager capsule futhi uthathe isinyathelo kazibuthe. Angase ukugqoka ama-headphone ekhethekile, ngoba umshini kunomsindo ngempela okukhulu. MRI sinemakrofoni ngokusebenzisa ukuxhumana senzeka udokotela lesiguli. Lawo aboniswa kukhompyutha ngomfanekiso ngakuthathu. izinso MRI ihlala akukho kuka imizuzu engu-30. Isithombe nencazelo kuvame ibhalwe ngosuku olufanayo.

MRI we komgodi ongaphakathi kwamathumbu nge Ngokuphambene

Ukutadisha okunjalo ezinqunyiwe uma kukhona izinsolo we khona kuwuphawu lwesimila. Kulolu daba injected into edabula izitsha uqala ukudweba kubo buthelela kwezitho nezicubu. Ikhwalithi yesithombe kuxhomeke ezingeni esiphakamisa lapho oyifunayo esebenzayo esifundeni egazini. Inani iqondiswa Ngokuphambene, ukugxila isisindo lesiguli. Lokhu kwaziswa esuswa umzimba ne umchamo emini.

Ngenxa yalolu cwaningo, ungabona izinhlumba nomgodi obukhulu imfundo volumetric. Ngaphezu kwalokho, izithombe ukuhlola uketshezi kule simila nokuvuvukala ukuhlolelwa lesi sifo futhi opha. inqubo enjalo is contraindicated ekukhulelweni.

Abantu abaningi bayazibuza mayelana uma esimisiwe MRI izinso, lapho ukwenza isifundo esinjalo. Ingabe i-zokuxilonga MRI izikhungo, okuyinto beba more and ngenxa ukuthandwa futhi okusezingeni eliphezulu inqubo ukunemba.

isiphetho

Ngakho, uma udokotela ngaphambilini i-MRI izinso, akudingekile ukuba wesabe cwaningo, ngoba nakanjani ephephile. Kodwa kukhona ukulinganiselwa ezithile ngoba ndima yayo, futhi udokotela kufanele wazise nesineke.
