Uyini umehluko CT nama-MRI? tomography Otherness

Lapho kwakukhona umshini-X-ray, kwaba intuthuko enkulu kwezokwelapha. Lokhu sekwenze kwaba lula ukubona iziyaluyalu yangaphakathi emzimbeni womuntu, kwezitho zawo zitholakala ngasiphi isimo. Kodwa ngisho indlela enhle okunjalo kuletha ezithile. Ngokwesibonelo, e-X ray, ungathatha isithombe sezinga kwezinye izitho, kodwa kuyenzeka ihlangane nesithombe nezinye izitho.

Futhi kulokhu, kungaba ukuqhaqha okuholela udokotela kakhulu abanolwazi futhi onolwazi. Ngakho-ke, ngenxa lezi nemiphumela ethile engathandeki, intuthuko usephendukele olwengeziwe.

izindlela ezintsha

Namuhla, kunezindawo nezinye izindlela ekuxilongweni izitho zangaphakathi ezifana CT noma i-MRI. Kodwa ngalesi sikhathi kukhona imibuzo eminingi. Ngokwesibonelo, abanye ukuhlola ukukhetha ukuthi yini umehluko CT nama-MRI? Ngaphezu kwalokho esihlokweni, sizokwenza ukuyichaza ngokuningiliziwe indlela bayehluka. Siphinde ukuchaza lokho uphethwe ezisilungele xaxa endabeni ethile.

Siyaqonda umehluko CT nama-MRI

Manje, odokotela abaningi batusa iziguli ukuxilongwa okungcono ukuqhuba ukuhlolwa ngokuphelele, ukusebenzisa ikhompuyutha noma resonance kazibuthe a imaging. Hlobo luni ucwaningo? Ngikuphi okuhlukileko kuneGreyidini CT MRI? Ake sihlolisise:

• CT - a tomography ikhompyutha, esiqhutshwa ngokusebenzisa impahla rentgenizlucheniya ehlukile amuncwa ezahlukene izicubu ukujiya. Okungukuthi, CT, ngokuvamile, nsé-X-ray, kodwa etholwe ngosizo ulwazi kusetshenzwe ngendlela ehluke, futhi ukuchayeka emisebeni eyingozi kuba okuningi kunalokho.

• MRI (magnetic resonance imaging) wenziwa usebenzisa amandla kazibuthe. ama-athomu ye-hydrogen, ngenxa imiphumela yayo, ushintsha indawo yokuhlala, isithwebuli siletsa umphumela nezinqubo esithombeni ngakuthathu.

Njengoba ubona, umbuzo uwukuthi - lokho kuhlukile CT MRI, uyini umehluko phakathi kwalezi amadivayisi amabili zokuxilonga - ngokushesha basabela. Umehluko oyinhloko ubunjalo amagagasi. Ngo-magnetic resonance imaging - amagagasi kagesi. Lapho sinomthelela ezahlukene isitho kwezicubu, sibonga ngaleli qiniso, ezihlukahlukene idatha ofundiwe idivayisi umshini. Bese wonke amasignali okwenziwa futhi, njengoba nge-CT luhlolo, qapha isithombe unikezwa. Siyabonga kuye udokotela ithuba lokubona tincetu ngisho egqinsiwe kusukela emizimbeni. Ngaphezu kwalokho, isithombe kungaba sizungeziswe futhi, uma kunesidingo, ukwandisa indawo oyifunayo.

Yini enye kukhona umehluko phakathi CT nama-MRI? Yini imaging kangcono? ukuxilongwa ngamunye okuhle nokuwusizo. Umehluko omkhulu itholakala uhlobo zokugula kungatholakala yilezi izindlela, futhi ngaphezu kwalokho, ngosizo abanye imisebe lokhu kwenziwa.

Umehluko ngesikhathi scan

Ukukhuluma umehluko CT nama-MRI, kuyafaneleka ukuthi computed tomography (i-CT) has a ukuchayeka sina ngemisebe, ngakho-ke asikwazi wayevame ukusebenzisa. Kodwa rentgenizluchenie kuthinta izinhlaka hhayi ngemizuzwana engaphezu kwengu-10. Lokhu kusho ukuthi ucwaningo esinjalo arcade kwenziwa nabantu abaphethwe claustrophobia.

Magnetic resonance imaging kuyinto (MRI), izithombe ngokuvamile Uthatha imizuzu eyishumi noma ngaphezulu, kuye ngokuthi indawo yocwaningo. Ngakho-ke kuye kudingeke baqhube namanje. Ngakho-ke, i-MRI kuyinto ekahle ngalabo abangenazo ngeziphambeko sína psyche. Njengoba for the izingane, usebenzisa i-magnetic resonance imaging, basuke anesthetized.

Ngokusekelwe osekushiwo, sizwisise umehluko phakathi MR ukuze CT. Yini engcono MRI noma CT scan ngawe? Lo mbuzo ungaphendulwa udokotela kuphela, esekelwe izici zomzimba wakho.

Lapho usebenzisa i-MRI?

abantu Abangenalwazi abaphethwe yizifo ngezifo, ebhekisela udokotela, cela ngalokho kuhlukile CT MRI. Kodwa njengoba sikhuluma ngolunye usuyitholile kakade impendulo, bese uqhubeke ukukhuluma, ngasiphi izifo kungcono ukusebenzisa i-MRI, nalapho - CT.

MRI inikeza ulwazi oluphelele kakhulu unikezwa ekuhloleni izicubu zomzimba ezithambile. Ngakho-ke, it is ebekiwe kulezi zimo ezilandelayo:

• uma umuntu ezemfundo izicubu imisipha, amaseli fat esiswini kanye ukhalo (lokhu kwenziwa ukuze uthole isithombe esigcwele ngemva kwesifundo usebenzisa ultrasound);
• yezifo ezihlukahlukene zobuchopho nomgogodla;
• uma kukhona izinsolo ukuthi ubuchopho noma umgogodla intambo endaweni kukhona ukuphazamiseka e ukugeleza kwegazi;
• uma ufuna ukuhlola akwazi ukugcina intervertebral noma isimo kwezicubu ngokuhlanganyela.

Futhi uma kusetshenziselwa tomography kukhompyutha? It ezinqunyiwe:

• isifundo ithambo izicubu endaweni yomgogodla nezihlanganiso;
• lapho ithambo kuthintwa zokwakheka isimila;
• lapho amathambo asemzimbeni kwavele ukuhlukumezeka;
• pathologies e besisu, okhalo, futhi wamaphaphu;
• izinguquko atherosclerotic ku isimiso semithambo yegazi.

Izimo

Ngesisekelo lokho okuye ezichazwe ngenhla, udokotela uzokwazi ukukhetha uhlobo olufanele uphethwe isiguli ngayinye. Kodwa kukhona ezinye Izimo, okuyinto kufanele kubhekwe.

Lezi zihlanganisa lokhu okulandelayo:

1. CT akuvunyelwe ngesikhathi sokukhulelwa.
2. MRI aluboniswa:

• ebukhoneni zensimbi futhi Wawufaka umzimba;
• lapho ekhona izicubu zobuchwepheshe (isib umshini wokulawula ukushaya kwenhliziyo);
• abaphethwe claustrophobia;
• umuntu nge isisindo 150 kg;
• iziguli ezinokuphazamiseka zezinzwa abangakwazi ukuhlala isikhathi eside ngendlela efanayo.

Ekugcineni, inkampani encane

Umbuzo kuyini okungcono survey ezimbili ukukhetha, cela umuntu ngamunye abayobe ihlonzwe izitho zangaphakathi. Futhi ukuze hhayi ukulimaza impilo yabo, futhi ukuthola ulwazi oluningi oluwusizo, isiguli udokotela wakho kumelwe sizibuze, uyini umehluko CT nama-MRI. Futhi Ochwepheshe ukusiza ukuthola ukuthi isiguli ezifanelekayo esimweni ngasinye.
