Yintoni MRI welungu idolo njengoko ukwenza oko kuya MRI of idolo?

Ilunga kwedolo yeyona kwabona bangakhuselekanga kwinkqubo musculoskeletal yabantu. Kungenxa yoko le nto uxilongo yokwenzakala idolo - ingxaki ngenene Traumatology. Kwedolo elifanelekileyo ngokudibeneyo umfanekiso yokuzoba ingqalelo livakale umfanekiso magnetic (MRI). Ngalo ungenza ukuxilonga iintlobo yokwenzakala, ukuqala nemisipha baxakwe kunye waphuka nesiphelo. Yintoni MRI le idolo? Njani le mishini? Kwezi zinto ukuba zinokulungiswa ngayo ngaphandle.

Anatomy of the joint idolo

Le ezimbaxa yeyona inkulu emzimbeni womntu. Bone idolo nezisekelo - yifemur kunye lesiquluba kunye patella. Lesiquluba akukho ngokunxulumene ukuya entlanganweni. Umphezulu wethambo uyila ezimbaxa, Bathiwe wambu intlala. Ngenxa it kunciphisa umkhosi zochuku kunye lula intshukumo kuyaqinisekiswa.

Ekupheleni distal ye yifemur ezimbini condyle - osecaleni (ngaphantsi) kunye medial (enkulu). Zinelungelo imilo ngeenxa zonke. Condyles apho kwaye ekupheleni proximal le lesiquluba. Ewe tyaba. Phakathi kwazo ukusukelwa iindawo ke menisci (nomphandle wocango) - intlala falcate. Ukuba kuzinziswe le kwedolo, wenza indima bothukile absorber kuyo.

Ilunga idolo eyedwa ngeentambo ezininzi lokuqinisekisa ukuzinza kwalo:

• tibialis (medial) mali;
• lesiquluba (lateral) mali;
• cruciate sobuKristu;
• cruciate ngomva.

Isakhiwo kwakhona iquka imicu edolweni. Ngaphambi kokuba siqwalasele MRI welungu idolo, nto leyo ebonisa ukuba kubalulekile ukuqaphela ukuba kwiimeko ezininzi yonakele imicu kwemisipha quadriceps. sekhefu lakhe ngenxa ucutheko ngesiquphe izihlunu. Ngamanye amaxesha ukulimala abafunyenwe kwaye imicu ashinyeneyo ebanzi iliotibialnogo phecana. Esi sakhiwo i uzinziso eyomeleleyo osisi olutshintshayo entlanganweni idolo.

Ubungqina obubonakalayo buxela ukuba MRI

Umonakalo kwizakhiwo ze edolweni kwenzeka kaninzi. Le iingcali ngokuyintloko kufuna abantu abatsha aphile esebenzayo yokuphila kunye umthambo. Phambi ukubonelela uncedo koogqirha zazide MRI. Le ndlela echanileyo kwaye ithembekile ngenxa uxilongo iingozi ezahlukeneyo.

Ngo-MRI of edolweni, kukho izikhokelo ezivela ethile. Ezi ziquka:

• umonakalo ukuba akananto kunye cruciate nemisipha;
• phula ingqibelelo meniscus okanye imisipha;
• eko zaphuka;
• intlungu emadolweni;
• ulwazi iinkcukacha ezifunyenwe ngokusebenzisa ray.

Izimo ukuba isifundo

"Yini MRI welungu kwedolo unyawo?" - umbuzo apho kungase kufunwe impendulo, asingabo bonke abantu, kuba le ndlela loxilongo kukho Izimo:

• phambi kwe-ntliziyo (kwesincedisi-), umsebenzi yayo yaphulwe ngenxa sifundo;
• kuthelekiswa umboniso imithambo yegazi metal ezinokuthi utshintshile ngenxa yempembelelo lo mhlaba otsalayo;
• Ukukhala isigulana;
• bephelelwa umoya;
• ukuxilongwa ferromagnetic, ngenxa apho Tyhila ukuphuma imifanekiso ngendlela echanekileyo wagqwetha iziphumo zophando;
• ukukhulelwa ukuya kwiiveki ezili-12.

Kolu luhlu kumelwe kuphawulwe bephelelwa umoya. Asiyonto contraindication ngokupheleleyo. Xa okubonakalisa yokoyika yomguli lokusetyenziswa isithuba umthomalalisi ezivaliweyo yavalelwa okanye zomzimba ayikho nzulu.

ucwaningo

wenza njani MRI ngayo idolo - kwisihloko eshushu abantu, nabaqeshwe yile nkqubo. Ngoko ngaphambi kokwenza izigulane MRI mchazele ukuba bafake zambatho ezikhethekileyo. Unako ukuhlala izinto zabo, ukuba kungekho amaqhosha yesinyithi, iiziphu. Phambi kwesi sifundo kuza kufuneka asuse yonke nezacholo, izibuko, iiwotshi, asuse ezipokothweni yezitshixo, cell phone.

Uvavanyo lwenziwa kunye lisalele nomonde. Imilenze zibekwe kwi sixhobo. Ngexesha kuphononongo umlenze eyonakeleyo na Ikhoyili sokuquqa kwerediyo. nomlenze okunempilo ome kuyo. Phantsi umlenze uphando lufakwe apha irola encinane. Kuyimfuneko ukuba nokuthelekelela intle lungu cruciate.

Ukuba kukho urhano ubukho ithumba, ngoko wenza umahluko MRI. Phambi lokulingwa umthambo yokuba umguli ilawulwa into ekhethekileyo. Kuyimfuneko ukuqinisekisa ukuba MRI kwedolo kwabonisa nethumba.

komzimba MRI welungu idolo

Kuba uphethwe echanekileyo kubalulekile ukwazi ukuba MRI iza kubonisa ngedolo eziqhelekileyo. Nantsi ke inkcazelo iinkalo eziphambili idolo:

1. Xa cruciate akudala oqhelekileyo lungu kwi T2-T1 kunye VI-VI Kubonakala ngathi isakhiwo ezimnyama kwelona homogenous umqondiso eliphantsi. Ngomva cruciate lungu kwi imifanekiso ezifunyenwe MRI, oko libonwa ngohlobo kakuhle echazwe yohlobo olunye intambo emnyama.
2. Tibial kunye fibular akananto lungu ngesiqhelo wasinika T2-T1 kunye VI-VI yohlobo olunye ephantsi uphawu ngamandla.
3. menisci lesiqhelo on T2-T1 kunye VI-VI libonwa nezakhiwo njengoko ngokufanayo hypointense (ukuya abamnyama) kunye iinyanda luvo engundoqo kunye imithambo yegazi. Yakhiwe le menisci ecacileyo, umphezulu into kakuhle.
4. Imisipha ngokuqhelekileyo liphantsi kakhulu umqondiso azalwa. Kusenokwenzeka nokuba musani ndiyinike imifanekiso Kumiswe T1 kunye T2.
5. intlala Articular luphawulwa kwelona uphawu esisezantsi T2-VI nakumndilili uphawu ngobunzulu kwi T1-VI.

umonakalo lungu

Yokulimala kakhulu ezifanayo lungu lo cruciate sobuKristu. MRI ibonisa ukuba joint idolo yonakele olu donga? Ngexesha lekhefu ukwanda ngamandla uphawu ngaphakathi qela. Kukho inokuba discontinuity okanye ukungabikho uphawu yesiqhelo. Xa ukulimala fresh nzima iziphumo MRI Ukuthelekelela ubukho okanye ukungabikho ikhefu, kuba xa ukunyuka yokwenzakala lungu ngobukhulu (na ukudumba khona).

Ukwenzakala izibambiso lungu inokuba ikhefu olupheleleyo, iinyembezi buso kunye nomsantsa intraligamentous. Ukuba ufumana i ezonakeleyo tibial akananto lungu, ngoko ke uya waqaphela ukuqina. izabelo Bonakalisa ukwandisa umqondiso. Le nto ibonisa MRI idolo ngosuku lokuqala. Kamva, le nxalenye zinyamalale ngenxa ukufunxeka ulwelo kwemfuneko olubiyele nokulimala kwithishyu.

Breaks fibular izibambiso lungu bene, ngokuqhelekileyo ezinqabileyo kakhulu. ukulimala ezinjalo zidityaniswe kunye Ukophuka ezinkulu comminuted le tibial kwamathambo condyle ezingqonge kwizihlunu ezithambileyo.

umonakalo menisci

Kuba ukwenzakala idolo izakhiwo ezingamadlelane zithathwa ukuba imifanekiso kakhulu ulwazi afunyenwe kwi iinqwelomoya sagittal kunye coronal. Ukuze ukuvavanya kuyoba MRI of the amadolo, uxilongo, oogqirha ingqalelo mpawu zilandelayo:

• ubukhulu meniscus;
• uqwalaselo kwabo, uhlobo uphawu;
• ubukhulu kunye nobunzulu uphawu modified;
• kwasendaweni lotshintsho phakathi meniscus.

Ukuchonga ezininzi izidanga umonakalo meniscus :

1. isidanga sokuqala - engavezwanga central angakwazi. Ngexesha MRI utshintsho ziyazibhaqekela ngaphakathi meniscus. azibonakali ukuba oluphuma ngamandla uphawu.
2. bolwesibini udidi - a yamehlo eqhelekileyo engundoqo. Ngaphakathi meniscus liyanikezelwa kummandla obanzi eyandileyo ngamandla uphawu.
3. The degree sesithathu - meniscus eqwengiweyo. Ngaphakathi meniscus kutyhilwa engamandla uphawu kwalo. Aya yendawo intra-articular ezaphukileyo. Ngamanye amaxesha indawo amaqhekeza meniscus.

umonakalo imisipha

Uphando imicu idolo lwenziwa iinqwelomoya sagittal yezihlunu. Eyokuqala kwezi utshintsho libonwa ngokucacileyo ngaphezulu. Umonakalo kuqinisekiswa ukuba le miqondiso ilandelayo MR zafunyanwa ngexesha ngemagnethi ekuvakaleni kwelizwi umfanekiso:

• effusion imicu esingxotyeni (impendulo kakhulu ukuba ukucima kombane) okanye nokudumba peritendinoznoy kwi zomzimba lwamalunga (kwezo ndawo apho kungekho ndizayo);
• ukuqina okanye thinning of imicu;
• uphawu ukwahluka (kunye ngezifo sisiba mandundu le ndawo imicu engundoqo umkhondo longitudinally elubengezelo, esibonakala umqondiso hyperintensive kwi T1-VI);
• imicu ngokupheleleyo uqhekeko (ebhalisiweyo iziqwenga imicu ukudumba ngamandla uphawu oluguqulweyo kunye nentaba siziinduli).

kwamathambo

Ezinye ukulimala kwemininzi eqhelekileyo - a amathambo aphukileyo eyenza joint kwedolo. Ukuba Ukophuka okwenyaniso waphawula ukuhla linear yomqondiso kunye ikhefu wethambo cortical. Maxa wambi zashiya iziqwenga. Kusenokuba hemarthrosis - ukopha kungena kwisisu ehlangeneyo. It is on imifanekiso T1-weighted liba uphawu eliphezulu xa kuthelekiswa kulwelo serous.

Wabalasela nje ezingapheliyo (elide-emile) kwizaphuko, kuba abanye abantu emva kokufumana umonakalo, musa ukufuna uncedo lobungcali. Ngenxa yokulimala ezinjalo hypointense ebonakala, utshintsho nonuniform kunye iimpawu sclerosis inyama ezinezikhondo kunye nendawo medullary.

Iyafuna ucinga kunye nokwenzakala contusion (ukugruzuka) ithambo. Yintoni na idolo MRI kwezi meko? Kwezi limala kwenzeka iindumbisa ofaka kuphela. Lubonakala ngokuthi kwentamo yolahlo uphawu buthathaka kwi imifanekiso T1-weighted kunye nokwanda ngegalelo lako kwi imifanekiso T2-weighted. uphawu yezifo zingagcinwa iinyanga 3-10.

Xa ndiqukumbela, kubalulekile ukukhumbula ukuba joint idolo lonzakele rhoqo. Enye yezona ndlela ilungileyo moshilongo of izilonda elohlukileyo ngemagnethi ekuvakaleni kwelizwi umfanekiso. It zinezibonelelo ezininzi. Okokuqala, lo phando ulwazi kakhulu. It ivumela nezifundiswa ukuhlola imeko amathambo kunye kwizihlunu ezithambileyo. Okwesibini, livakale umfanekiso magnetic akuyongozi kwizigulana (kungekho Izimo). Le nto babelwe MRI of edolweni abantwana kunye nabantu abadala.
