Ngikuphi okuhlukileko kuneGreyidini i-MRI CT? Kwezinye izimo, i-MRI CT kungcono?

imithi ezingeni okwamanje ngempela eliphezulu. Kukhona izifundo amaningi akuvumela ukuba ukuxilonga ngokunembile. Esikhathini arsenal lodokotela - ubuchwepheshe bamuva. Ngosizo lwabo kungenzeka ukubona ngaphakathi emzimbeni womuntu futhi embule zokugula ekuthuthukiseni noma ukusebenza kwe-izitho zangaphakathi.

Lezi zindlela ezintsha zokuxilonga zihlanganisa resonance kazibuthe kanye tomography ngekhompyutha. Lezizifundo avame ukusetshenziswa ukuqinisekisa uphethwe. Eziningi zalezi nezinqubo ngaphandle yokudluliselwa kadokotela. Kulokhu, kubalulekile ukwazi umehluko phakathi i-MRI ukuze CT.

Umgomo we operation

Naphezu kweqiniso lokuthi ngenxa kokubili izifundo etholwe isithombe ezintathu-ntathu of kwezitho zangaphakathi, kukhona umehluko kubalulekile phakathi kwawo:

• Ngokusho degree of ukuzwela.
• Ngu isimiso isinyathelo.

CT scanner usebenza ngokusebenzisa X-ray. Kuyinto lonke ukufakwa, okuyinto uzungeza yangibamba umzimba wesiguli, uthatha izithombe. Zonke izithombe okuholela ke kwengezwe ndawonye, nokwelashwa kwazo ukwenza computer.

Ngokungafani MRI CT ngokuyisisekelo isebenza wukuthi lapha akukho-X ray, futhi isevisi yomuntu aqukethe kazibuthe. Ngaphansi kwethonya ama-athomu ye-hydrogen ekhona emzimbeni wesiguli, siqondile kuhambisana magnetic field isiqondiso.

Idivayisi ithumela ishayela RF, okuyinto perpendicular main kazibuthe. Izicubu emzimbeni womuntu angene resonance kunyakaza futhi la mangqamuzana isithwebuli ingaze, acacise kubo futhi ukwakha izithombe egqinsiwe.

Izimpawu ze-MRI kanye CT izinqubo

Kukhona izifo okuyiwona akukho mahluko abalulekile, lokho cwaninga uzoba ukudlula. Njengoba omunye, futhi iyunithi yesibili uzokwazi ukunikeza umphumela olunembile.

Nokho, kukhona pathologies lapho kuhle ukucabangela ukuthi ngcono - MRI noma CT?

MRIs evame ukunikezwa uma kukhona isidingo uthole ukucwaningwa okuningiliziwe kokulandisa izicubu ezithambile emzimbeni, isimiso sezinzwa, emisipheni nasemalungeni. On lezi zithombe wonke pathologies ibhalwe kahle.

Kodwa nohlaka lwamathambo ngenxa okuqukethwe encane hydrogen proton kabi isabela emisebeni kazibuthe, futhi umphumela kungenzeka ingabi olunembile ngokuphelele. Kulezi zimo kungcono ukuqhuba scan CT.

CT futhi sikwazi ukunikeza isithombe kweqiniso ekuhloleni izitho eziyize ezifana ingaphakathi lesisu, amathumbu namaphaphu.

Uma sikhuluma izifo, le-MRI kuboniswa ngenxa:

• Stroke.
• Ukuhlonza Ukugula izifo kwezitho okhalo.
• Ukutadisha uqhoqhoqho emphinjeni futhi imithambo yegazi.

I-CT scan kungcono ukuqhuba ucwaningo:

• uhlelo zokuphefumula.
• Sezinso.
• Izinhlaka komgodi ongaphakathi kwamathumbu.
• Uhlelo lwamathambo.
• Lapho kuhlolwa indawo esiqondile ukulimala.

Ngakho, kuyacaca ukuthi i-MRI kanye CT umehluko itholakala amaphuzu ezahlukene isicelo.

Izimo ekusetshenzwa

Naphezu ukusebenza yayo, kokubili amadivaysi babe Izimo. Ngokuvamile iziguli kadoti ngekhompyutha tomography funa kwama-X ray. Ekuphenduleni umbuzo ukuthi kuphephile, i-MRI noma-CT scan, bona sithambekele kukhethwa esifundweni sokuqala.

Ukuhlolisisa kungenziwa kuphawulwe ukuthi kokubili zilwane Izimo yayo.

Ngikuphi okuhlukileko kuneGreyidini i-MRI CT, kuba izinkomba zabo. computed tomography ayiboniswa:

1. Abesifazane abakhulelwe (ngenxa ingozi njalo yokuchayeka emisebeni ye ezingenzeka embungwini).
2. izingane ezincane.
3. Ukuze njalo.
4. Lapho khona Gypsum emkhakheni ucwaningo.
5. Ngo esingamahlalakhona kwezinso.
6. Phakathi ibele.

Magnetic resonance imaging Ubuye Izimo yayo:

1. Claustrophobia, lapho umuntu asaba izikhala avaliwe.
2. Ukuba khona emzimbeni we pacemaker.
3. Senyanga yokuqala sokukhulelwa.
4. isisindo elikhulu umzimba (110 kg).
5. Ukuba khona metal izimila, isibonelo, emalungeni.

Zonke lezi Izimo ngokuphelele, kodwa ngaphambi inqubo, kufanele bonana nodokotela wakho kuqala, mhlawumbe uma zakho nazo izincomo ezithile.

Izinzuzo-magnetic resonance imaging

Ukuze siqonde ukuthi kungcono - MRI noma-CT scan, kudingeka ucabangele izinzuzo uhlobo esifundweni ngasinye.

Magnetic resonance imaging has a lot of izici ezinhle:

• Lonke ulwazi lunembile kakhulu.
• Lena indlela abaningi ulwazi sokutadisha iziguli ezine izilonda isimiso sezinzwa esiyinhloko.
• Ngokunembile ukuxilonga hernia vertebral.
• Kuyinto luhlolo ephephile abesifazane abakhulelwe kanye nezingane.
• Kungasetshenziswa nge ukuvama okudingayo.
• Kasibili kobuhlungu.
• Bathola izithombe ezintathu-ntathu.
• Kungenzeka ukugcina ulwazi kumemori sekhompyutha.
• Amathuba yokuthola ulwazi okungalungile cishe zero.
• Ayikho ukuchayeka-X-ray.

Banikezwe izici ithuluzi futhi isimiso yayo wokusebenza, ngesikhathi isifundo kungenzeka sidilize elikhulu, okungadingi kudingeke wesabe, ungasebenzisa ama-headphone.

Izinzuzo ngekhompyutha tomography

Ngokubukeka, kokubili tomograph zifana kakhulu. Waba yini umphumela wesibindi umsebenzi wabo futhi kungagcini ukukhiqizwa izigaba ezondile ezindaweni wafunda esithombeni. Ngaphandle ukutadishwa kunzima kakhulu ukutshela umehluko phakathi MR ukuze CT.

Izinzuzo CT zihlanganisa amaqiniso elandelayo:

1. It kuvela isithombe ezintathu-ntathu of the indawo yokutadishela.
2. Sula izithombe nohlaka lwamathambo.
3. Abukho ubuhlungu phakathi naleyo nqubo.
4. Yonke cwaningo kuthatha imizuzu embalwa.
5. Ukuba lula futhi lithembekile ulwazi.
6. MRI ihlinzeka umthamo ephansi emisebeni kuka umshini-X-ray.
7. Angahlolwa ebukhoneni metal kagesi noma amadivayisi emzimbeni.
8. Inikeza ulwazi kweqiniso futhi olunembile ukopha zangaphakathi, isimila ukuthola.
9. Izindleko ezingaphansana kuqhathaniswa MRI.

Njengoba ubona, isithwebuli CT neze kunabayeni izinzuzo kwabo resonance kazibuthe, ukuze kungcono - MRI noma CT, kufanele zithunyelwe esimweni ngasinye.

Nemibi uhlobo ucwaningo ngamunye

Ngaleso sikhathi samanje cishe zonke izinhlobo survey benomthwalo ezicini ezinhle kanye nobubi obuthile. Izikena kulokhu iyathinteka.

I nemibi MRI ukuhlola amaqiniso elandelayo:

• Kunzima ukufunda ezithweni eziyize ezifana urinary kanye nenyongo sesinye, emaphashini.
• Metal izingxenye emzimbeni womuntu kuyoba isithiyo inqubo.
• isikhathi esiningi liyadingeka nakanjani esifundweni.
• Ukuze uthole imiphumela kweqiniso futhi lunembile isikhathi eside isiguli kumele sibe sesimweni esinqunyiwe.

Ngekhompyutha tomography Ububi bayo:

• Ucwaningo alinikezi ulwazi mayelana nesimo sokusebenza kwezitho nezicubu kuphela kodwa kuphela isakhiwo sabo.
• Emiphumeleni elimazayo X-ray.
• Contraindicated abesifazane abakhulelwe kanye nezingane.
• Le nqubo ayikwazi kwenziwe njalo.

Uma Kunconywa kokubili izindlela zocwaningo, kulesi simo, kungaqali ndaba okuningi ukuhluka i-MRI CT.

izindlela ulwazi

Ngemva kokuvakashela udokotela, uzobe esihleliwe ukuhlolwa, okuyinto, ngokubona udokotela, ukunikeza yi kweqiniso futhi kunembile.

Uma unquma ukuba ulinde izincomo, kubalulekile ukwazi lapho izimo iyiphi idivayisi ukukhetha.

Uma ungazi ukuthi yini ngqo - MRI noma-CT scan, khumbula ukuthi MRI izonikeza Imiphumela esinembile futhi ulwazi ngaphansi pathologies ezilandelayo:

1. ebuchosheni, isifo sohlangothi kanye multiple sclerosis.
2. Zonke izifo emgogodleni.
3. zokugula Intracranial we izinzwa nobuchopho.
4. Ukulimala ezicubwini.
5. Soft izicubu lwesimila.

Uma eziwukwephulwa okukhulu imisebenzi ebalulekile, kubalulekile ukuba eminye bonana nodokotela wakho kuqala.

Olunye ulwazi oluningiliziwe CT intando, uma ikhona:

• Okusolwayo ukopha intracranial, ukuhlukumezeka.
• Umonakalo isifo ithambo.
• Pathology umgudu wokuphefumula.
• Atherosclerotic izilonda semithambo.
• Izilonda ebusweni skeleton, yegilo.
• Otitis futhi sinusitis.

cwaningo preoperative sizonikeza swe ku ukuhlinzwa oluzayo.

Uma bakholelwa ngokuqinile uphethwe okusolakala, futhi ungakhetha indlela yakho siqu zocwaningo.

Umahluko omkhulu izindlela

Naphezu ukufana eziningi kangaka, umehluko phakathi CT nama-MRI Usekhona. Uma endaweni amaphuzu ambalwa, bese sikwazi basho lokhu okulandelayo:

1. Umehluko ezibaluleke kakhulu phakathi kwalezi zindlela ezimbili zocwaningo itholakala isimiso sabo wokusebenza. MRI isebenzisa amandla kazibuthe, nakuma-CT - x-reyi.
2. Bobabili izindlela ingasetshenziswa ukuxilonga lenqwaba pathologies.
3. Nge umphumela Kungenzeka okufanayo kulinga MRI ukukhetha, njengoba kulolu cwaningo ivikeleke kakhulu, kodwa kubiza ngaphezulu.
4. Inqubo ngayinye ine Izimo yayo, ngakho kudingeka uqaphe lapho kubhekwa ngaphambi kokwenza ukukhetha sokugcina.

Khumbula, impilo yakho kusezandleni zakho, futhi ngezinye izikhathi akunandaba ukuthi hlobo luni indlela zokuxilonga esetshenziswa, into ebaluleke kakhulu - ukuthola isikhathi okunembile nokuyiqiniso futhi ezinhle kakhulu sokuqala ukwelashwa.
