Kuyini MRI we ngokuhlanganyela amadolo njengoba enza ezokwenza MRI we amadolo?

Joint amadolo kuyinto ngezinyamazane ezibuthaka kunezinye ohlelweni womuntu zemisipha. Yingakho sitholakele ukulimala edolweni - kuyinkinga langempela traumatology. I enhle amadolo imaging ngokuhlanganyela amasu kubhekwa i-magnetic resonance imaging (MRI). Nayo ungakwazi ukuxilonga ezihlukahlukene ukulimala, eziqala nemisipha edabukile futhi waphuka langesikhatheso ngoKukhulamungu. Kuyini MRI we amadolo? kanjani amaskeni? Kulezi nezindaba okufanele alungise.

Anatomy of the joint amadolo

Le ngxube iyona enkulu kunazo zonke emzimbeni womuntu. Bone amadolo izisekelo - kunawo futhi tibia kanye patella. Fibula ayinakho maqondana ngokuhlanganyela. Ingaphezulu ithambo ukwakha kwakwakhe, embozwe uqwanga. Ngenxa-ke kunciphisa amandla ukuxabana futhi kalula ukunyakaza kuqinisekiswa.

Ekupheleni distal ka kunawo wonke has ezimbili condyle - lateral (engezansi) kanye medial (elikhulu). Banezinhliziyo round ukuma. Condyles khona kanye ekupheleni proximal we tibia. Ziyakwazi owendlalekile. Phakathi kokuzalela evele kukhona menisci (yangaphandle futhi kwangaphakathi) - uqwanga falcate. Bona usimamise kwedolo, wenziwa indima ukushaqeka mfutho kuwo.

Joint amadolo ahlukanisa izintambo eziningana ukuqinisekisa ukuzinza yayo:

• tibialis (medial) eseduze;
• fibula (lateral) eseduze;
• cruciate anterior;
• cruciate posterior.

Isakhiwo sihlanganisa umsipha kwedolo. Ngaphambi kokuba ucabangele MRI we ngokuhlanganyela amadolo, elibonisa kuyafaneleka ukuthi ezimweni eziningi ezilimele umsipha kwemisipha quadriceps. break yakhe ngenxa ukusikwa okungazelelwe kwemisipha. Ngezinye izikhathi ukulimala uxilongwe futhi obukhulu umsipha ezibanzi iliotibialnogo ipheshana. Lesi sakhiwo kuyinto sinjalo eqinile lateral othakazelisayo joint kwedolo.

Izimpawu ze-MRI

Ukulimala izakhiwo kwedolo zenzeka kaningi. I ochwepheshe ngubani ngokuyinhloko ukufuna intsha ehamba phambili yokuphila asebenzayo kanye nokuzivocavoca. Ngaphambi ukunikezwa usizo kodokotela kwenziwe i-MRI. Lena indlela nalikhuluma ngemlandvo futsi letsembekile ukuze kuhlonzwe yokulimala ehlukahlukene.

Ngo-MRI ka kwedolo, zikhona izinkomba ezithile. Lezi zihlanganisa:

• kungenzeka umonakalo okuhambisayo futhi cruciate nemisipha;
• yokwephula ubuqotho meniscus noma imisipha;
• okusolakala ukwa;
• ubuhlungu kwamadolo;
• Imininingwane sebhithi sizila-X ray.

Izimo isifundo

"Uzothini MRI we ngokuhlanganyela nedolo unyawo?" - umbuzo lapho Impendulo ingase icelwe, akubona bonke abantu, ngoba le ndlela ukuxilongwa kukhona Izimo:

• khona pacemaker (pacemaker), umsebenzi okuyinto zingephulwa ngenxa cwaningo;
• esikhulu Ukugunda imithambo yegazi metal ukuthi kungenziwa sigudluke ngenxa ithonya kazibuthe;
• Usizi ubekezele;
• claustrophobia;
• izimila ferromagnetic, ngenxa okuyinto Ihambe hhayi izithombe ngempela lesifanele uhlanekezelwe imiphumela yocwaningo;
• sokukhulelwa amasonto 12.

Kusukela kulolu hlu kufanele basho claustrophobia. Ingane ayisona contraindication ngokuphelele. Lapho ukubonakaliswa yokwesaba yokuthi ogulayo uphelelwa avaliwe futhi yavalelwa ukusetshenziswa isikhala ukupholisa noma izinzwa akuyona ejulile.

ucwaningo Ukuqhuba

Kanjani MRI ka kwamadolo - esematheni kubantu, abamiswe le nqubo. Ngakho ngaphambi kokwenza iziguli MRI ukunikela ukuba agqoke izingubo ezikhethekile. Ningahlala izinto zabo, uma zingenalo izinkinobho zensimbi, bensimbi. Ngaphambi sihloko sizoqinisa udinga ukususa wonke amatshe ayigugu, izibuko, amawashi, susa kusukela ekhukhwini okhiye, umakhalekhukhwini.

Iskena wenziwa ne lisalele nesineke. Imilenze ezibekwe ku insimbi. Phakathi nesifundo umlenze obonakele ungaphakathi ikhoyili omsakazo. esitho okunempilo parallel ke. Ngaphansi umlenze kucwaningwe is lalibe selibambe roller encane. Kubalulekile ukubona ngeso okuhamba phambili umsipha cruciate.

Uma kukhona izinsolo ngoba khona isimila ke wenza Ngokuphambene MRI. Ngaphambi kokuhlola e vein yesiguli iqondiswa isakhi esithile esikhethekile. Kuyadingeka ukuqinisekisa ukuthi i-MRI amadolo yabonisa yesimila.

anatomy MRI we ngokuhlanganyela amadolo

Ukuze okuyikona kubalulekile ukwazi ukuthi MRI sizobonisa kwedolo kuyinto evamile. Nansi incazelo yezingxenye eyinhloko kwedolo:

1. Encwadini evamile anterior cruciate umsipha ku T2-T1 kanye VI-VI libukeka isakhiwo black nge homogenous ongaphakeme isignali umfutho. Posterior cruciate umsipha e izithombe etholwe MRI, ke libonakala ngesimo kahle ichazwe eyohlobo black intambo.
2. Tibial futhi fibular eseduze umsipha ngokuvamile ukunikeza ku T2-T1 kanye VI-VI eyohlobo ongaphakeme isignali umfutho.
3. menisci Jwayelekile ku T2-T1 kanye VI-VI ibukeke izakhiwo njengoba homogeneously hypointense (kufika ku black) nge central ezinzwa izinyanda futhi imithambo yegazi. Wabuka we menisci ecacile, amaqabunga abushelelezi.
4. Imisipha ngokuvamile liphansi kakhulu isignali esingokwemvelo. Zingase ngisho musa lona izithombe imisiwe T1 kanye T2.
5. uqwanga Articular elinesimo ongaphakeme isignali umfutho ku T2-VI futhi isilinganiso isignali umfutho ku T1-VI.

umonakalo umsipha

Ukulimala okuvame kakhulu ukuthi umsipha iyona cruciate anterior. MRI ebonisa ukuthi ilunga amadolo lilimele lolu gange na? Ngezinye ikhefu anda isignali umfutho ngaphakathi kweqembu. Kungase kube discontinuity noma ukungabi khona isignali evamile. Lapho ukulimala fresh nzima MRI Imiphumela cabangela khona noma ukungabi khona ikhefu, ngoba lapho umsipha ukulimala inyuka ngobukhulu (kukhona zokuzikhukhumeza).

Ukulimala eseduze umsipha kungaba ikhefu ephelele, ukudabuka esinqunyiwe kanye igebe intraligamentous. Uma uthola ezilimele tibial eseduze umsipha, khona-ke sizoba ukuqina. izingxenye manifest ukwandisa isiginali. Yilokhu ikhombisa MRI amadolo ngosuku lokuqala. Ngemva kwalokho, lezi zingxenye zinyamalale ngenxa ukumuncwa uketshezi ngokweqile enyameni ezungezile ukulimala.

Breaks fibular eseduze umsipha kutholakala ukuthi uphethwe yini, ngokuvamile kakhulu ezingavamile. ukulimala okunjalo ehlangana waphuka omkhulu comminuted we tibial condyle kwamathambo ezizungezile kwezicubu ezithambile.

umonakalo menisci

Ukuze ukulimala of kwedolo izakhiwo ngokuhlanganyela abhekwa izithombe kakhulu ulwazi olutholakale izindiza sagittal kanye nama-coronal. Ukuze ukuhlola uyosho MRI ka kwedolo, futhi uphethwe, odokotela banake izici ezilandelayo:

• usayizi meniscus;
• ukumiswa kwabo, ubunjalo isignali;
• ukujiya kanye isignali Ushintshe ukujula;
• kwasendaweni izinguquko ngaphakathi meniscus.

Thola eziningana degrees umonakalo meniscus :

1. degree Okokuqala - engavezwanga ngamazwi ukonakala emaphakathi. Phakathi MRI izinguquko kutholwa ngaphakathi meniscus. Babonisa sithuthukiswe isignali umfutho.
2. degree Okwesibili - emaphakathi ukonakala ezivamile. Ngaphakathi meniscus lihunyushwa ngokuthi indawo ebanzi ka anda isignali umfutho.
3. Izinga lesithathu - meniscus zidabukile. Ngaphakathi meniscus wembula okhushuliwe isignali umfutho. I nentaba of naphakathi-articular isikhala ngobugebengu. Ngezinye izikhathi isikhundla izingcezwana meniscus.

ukulimala imisipha

Kuphenywe umsipha amadolo wenziwa izindiza sagittal futhi Axial. Eyokuqala yalezi zinguquko ibukeke ngokucace kakhudlwana. Umonakalo kuqinisekisiwe uma MR izimpawu ezilandelayo itholwe ngenkathi magnetic resonance imaging:

• effusion umsipha emgodleni (impendulo ngokweqile ukuze overload) noma edema peritendinoznoy kwezicubu lwamalunga (kulezo zindawo lapho kungekho ulwelwesi);
• ukuqina noma thinning we umsipha;
• isignali ukushintshashintsha (nge zokugula esiwohlozayo central umsipha endaweni kuyofikwa longitudinally Ukubengezela, libhekene isignali hyperintensive ku T1-VI);
• Imisipha esengxenyeni umnyuziki ukudabuka (bhalisiwe ukuqina umsipha izingcezwana nge ezishintshwe isignali umfutho kanye nentaba mihlobiso).

ithambo waphuka

Ezinye Ukulimala okuvame kakhulu - a amathambo aphukile ukuthi zakha ngokuhlanganyela kwedolo. Uma waphuka kweqiniso waphawula ukwehla komugqa isignali nge break wethambo cortical. Ngezinye izikhathi dengwane izinsalela. Kungenzeka hemarthrosis - ukopha phakathi komgodi ngokuhlanganyela. Kuyinto ku izithombe T1-isisindo uveta isignali ephakeme kuqhathaniswa uketshezi serous.

Ikakhulukazi Kuyaphawuleka kukhona okungamahlalakhona (eside) Ngokuvamile abantu baphuka izinqulu, ngoba abanye abantu ngemuva kokuthola ukulimala, musa bafune usizo lobuchwepheshe. Ukuze ukulimala enjalo hypointense libhekene, izinguquko nonuniform nge izimpawu fibrous izicubu sclerosis nesikhala medullary.

It kuyafaneleka ukucabangela futhi contusion ukulimala (nemihuzuko) ithambo. Lisho ukuthini amadolo MRI kulezi zimo? Kulezi ukulimala zenzeka intraosseous ukuvuvukala elinganiselwe. It libhekene ekubhebhetselisa ebuthaka isignali iconsi ku izithombe T1-isisindo futhi ukwanda okujula yayo ku izithombe T2-isisindo. isignali sokugembula zingagcinwa izinyanga 3-10.

Ekuphetheni, kuyafaneleka ukuthi ngokuhlanganyela amadolo ilimele kaningi. Omunye izindlela ezingcono ukuze kuhlonzwe izilonda ezahlukene kuyinto-magnetic resonance imaging. It kunezinzuzo eziningana. Okokuqala, lokhu kucwaninga kakhulu. It ivumela ochwepheshe ukuhlola isimo amathambo nezicubu esithambile. Okwesibili, i-magnetic resonance imaging akuyona ingozi ngoba iziguli (ngokungabi bikho Izimo). Kungakho babelwe MRI ka kwedolo izingane kanye nabantu abadala.
