Waa maxay MRI wada jilibka ah sida samayn doonaa MRI ee jilibka ah?

si wadajir ah jilibka waa kuwa ugu nugul ee nidaamka muruqyada aadanaha. Taasi waa sababta cudurka of dhaawac jilibka ah - waa dhibaatada dhabta ah ee Traumatology. Farsamada wadajir imaging jilibka fiican waxaa loo tixgeliyaa imaging resonance magnetic (MRI). waxa aad ku aqoonsan karaa noocyo kala duwan oo dhaawacyo, laga bilaabo seedaha jeex iyo soo afjaridda jab. Waa maxay MRI ee jilibka ah? baaritaano ku Sidee? In arrimahan in la xalliyo.

Anatomy ee wadajirka ah jilibka

Xarunta Tani waa ugu weyn ee jirka aadanaha. Bone aasaaska jilibka - waa lafta bawdada iyo soo gaaray iyo patella ah. Loolalan ayaa la xiriirta si wadajir ah u lahayn. dusha sare ee xarunta lafta la xirrira ah, daboolay carjawda. Thanks in ay hoos u xoog khilaaf iyo hufnaan dhaqdhaqaaqa la hubinayaa.

Dhamaadka distal ee lafta bawdada u leeyahay laba condyle - lateral (hoose) iyo dillaac fudud (weyn). Waxay leeyihiin qaab wareegsan. Condyles halkaas oo dhamaadka proximal ee uu lugta ka. Waxay yihiin kuwa guri yihiin. Inta u dhaxaysa weheshiga sagxadaha yihiin menisci ah (Iska Fududeeyaan iyo gudaha) - carjawda falcate. Waxay xasilinta jilibka, oofiyey doorka absorber lama filaan ah waxa ku jira.

si wadajir ah jilibka ayaa waxaa go'doonsan dhowr xadhko hubinta ay xasiloonida:

• tibialis rahaamad (dillaac fudud);
• loolalan rahaamad (lateral);
• jilibka;
• cruciate dambe.

Dhismaha kaloo ka mid ah soo gaaray jilibka ah. Ka hor inta aadan ka fiirsan MRI wada jilibka, taas oo muujinaysa waxaa xusid mudan in kiisaska intooda badan ay waxyeello soo gaaray oo ka mid ah murqaha bowdada. Uu fasax ay sabab u tahay foosha lama filaan ah muruqyada. Mararka qaarkood dhaawacyo laga helaa oo soo gaaray ballaadhan cufan iliotibialnogo mareenka. Qaab dhismeedka Tani waa xasilinta lateral xoog firfircoon ee wadajirka ah jilibka.

Tilmaamayaasha for MRI

Burburka dhismayaasha ee jilibka dhacaan marar badan. takhasus kii ugu horrayn doondoonaan dadka dhallinyarada ah taasoo keentay hab nololeed firfircoon iyo jimicsiga. Ka hor bixinta kaalmada dhakhaatiirta fuliyay MRI ah. Tani waa hab sax ah oo lagu kalsoonaan karo lagu ogaado dhaawacyo kala duwan.

In MRI ee jilibka, waxaa jira tilmaamo gaar ah. Kuwaas waxaa ka mid ah:

• waxyeello suurto gal ah in dammiin iyo cruciate seedaha,
• ku xad daacadnimada ogeyn ama seed-adeegyada;
• looga shakisan yahay jab;
• xanuun jilibka ah,
• macluumaadka faahfaahinta helo raajada.

Sababo baadhitaan ah

"Waa maxay doono MRI wada jilibka iyo cagta?" - su'aal taas oo laga yaabaa in jawaabta la doondoonay, dadka oo dhan ma aha, maxaa yeelay, habkan of diagnosis waxaa jira sababo:

• joogitaanka pacemaker ah (pacemaker), shaqada, kaas oo la jebin karo sabab u tahay daraasadda,
• superimposed on clips xididdada dhiigga bir ah in lagu wareejiyay kartaa sabab u saamayn duurka magnetic;
• dhibaatada haysata ka mid ah bukaanka;
• cagajugleynta,
• implants ferromagnetic sababtoo ah taas oo soo baxay, sanamyadii ma arrin sax ah ku margado natiijada cilmi-baarista;
• ilaa uurka ilaa 12 isbuuc.

Laga soo bilaabo liiska this waa in aan soo magacawnay cagajugleynta. Ma aha contraindication sixun. Marka muujinta cabsi bukaan-socodka ee u xiran yihiin oo ay ku egtahay isticmaalka meel suuxin ama suuxdinta aan waa mool dheer yihiin.

cilmi Samaynta

Sidee MRI ee jilibka - mawduuc kulul loogu talagalay dadka, kuwaas oo loo magacaabay by nidaamka this. Sidaas hor fulinta bukaanka MRI bixiyaan inuu xidho dhar gaar ah. Waxaad joogi kartaa waxyaalaha ay, haddii ay leeyihiin ma badhamada biraha, jiinyeerrada. Ka hor inta daraasadda ayaa sidoo kale u baahan doontaa in aad ka saarto dahabka oo dhan, muraayadaha, soo jeedo, ka saar ka soo meelo ka mid ah furayaasha, telefoonka gacanta.

Iskaanka waxaa la sameeyaa iyadoo la jiifo bukaanka. lugaha waxaa la gelinayaa qalab ah. Inta lagu guda jiro daraasadda lugta dhaawacan waa in gariiradda inta jeer ee raadiyaha. Addinka Healthy waa isku midka ah in ay. Under lugta cilmi lifaaqan rullaluistemadka yar. Waxaa lagama maarmaan ah muuqaalaynta ugu fiican ee jilibka ah.

Haddii uu jiro shaki ah joogitaanka buro, ka dibna la sameeyaa barbardhigo a MRI. Ka hor inta jirrabaya ee xididka ah ee bukaanka ah waxaa maamula walax gaar ah. Waxaa lagama maarmaan ah si loo hubiyo in MRI jilibka tusay burada.

anatomy MRI wada jilibka

Waayo, cudurka saxda ah waxaa muhiim ah in la ogaado in MRI tusi doonaa jilibka ah waa caadi. Halkan waxaa ku qoran sharaxaad ka mid ah qaybaha ugu muhiimsan ee jilibka ah:

1. In jilibka caadi ah jilibka cruciate on T2-T1 iyo VI-VI u eg qaab-dhismeedka madow leh oo arkaayey hooseeyo signal. jilibka dambe ee images ka helay by MRI, waxaa visualized qaab wanaagsan u qeexan xadhig madow dhqaalaha.
2. Tibial iyo fibular jilibka sida caadiga ah siiyaan on T2-T1 iyo signal xoogga hooseeyo VI-VI dhqaalaha.
3. menisci Normal on T2-T1 iyo VI-VI visualized dhismayaasha sida homogeneously hypointense (ilaa madow) oo xidhmo xidhmo isugu dareemaha bartamaha iyo xididdada dhiigga. The contours ee menisci cad, dusha sare waa siman.
4. Seedaha signal soo jireenka ah sida caadiga ah aad u yar yahay. Waxay xitaa ma qaadsiin kartaa images of ganaax at T1 T2 iyo.
5. carjawda Articular waxa lagu gartaa xooga yar signal on T2-VI iyo xoogga signal celceliska on T1-VI.

dhaawac

The dhaawac ugu badan in ay soo gaaray waa cruciate ee jilibka. MRI waxay muujinaysaa in si wadajir ah jilibka uu waxyeeloobo dhismeedka this? At fasax kordhay xoogga signal gudahood farabadan ah. Waxaa laga yaabaa in soconin ama maqnaanshaha of signal caadiga ah. Marka dhaawacyo cusub adag by natiijada MRI xawilaan joogitaanka ama maqnaanshaha of nasasho, maxaa yeelay, markaan dhaawac kordhay size (waxaa barar).

Dhaawac jilibka laga yaabaa in nasasho dhamaystiran ah, jeex dhiman, oo faraqa intraligamentous. Haddii aad ka heli jilibka ah rahaamad tibial ay waxyeello, ka dibna waxa lagu arkay doonaa dhagid. qaybood oo Cad cad loo kordhiyo signalka. Tani waa waxa ay muujinaysaa MRI jilibka maalinteedii kowaad. Ka dibna, qaybo, kuwaas oo baaba'aan ay sabab u tahay nuugista of dheecaan xad-dhaaf ah ee dhaawaca unugyada ku wareegsan.

Biririf jilibka fibular cudurka, sida caadiga ah aad u dhif ah. dhaawacyo noocan oo kale ah lagu daro jab weyn comminuted khasaaraha lafta condyle tibial wareegsan unugyada jilicsan.

waxyeello ku menisci ah

Wixii dhaawac ah oo jilibka dhismeedka wadajir ah waxaa loo arkaa in ay ku images ugu wargelin helay in ay diyaarado sagittal iyo coronal. Si ay u qiimeeyaan wixii MRI doono oo jilibka ah, iyo cudurka, dhakhaatiir lacag bixisid si aad sifooyinka soo socda fiiro:

• size ogeyn,
• ay qaabeynta, nooca signalka,
• dhumucda iyo si qoto dheer ee signalka u habaynta;
• deegaamaynta ah isbeddellada la ogeyn xilliga ay.

Aqoonso dhowr darajo dhaawac jilibka :

1. degree First - xumaanshaha dhexe sheegin. Inta lagu guda jiro MRI isbedel la ogaan gudahood la ogeyn xilliga ay. Waxay Cad wanaajiyey xoogga signal.
2. Darajada labaad - a xumaanshaha caadi dhexe. Inside la ogeyn xilliga la buriyay gobolka ballaaran ee kor u kacay xoogga signal.
3. Heerka saddexaad - ogeyn dildillaacsan. Inside la ogeyn xilliga ay shaaca ka soo kordha xoogga signal. dusha ee meel intra-articular jebiyey. Mararka qaarkood booska jajabkii la ogeyn xilliga ay.

waxyeello ku seedaha

Baaritaanka seedka jilibka ah waxaa lagu qabtaa ah diyaaradaha sagittal iyo axial. The ugu horeysay ee isbedeladaan waxaa visualized si cad. Burburka waxaa xaqiijiyay haddii calaamadaha soo socda MR la ogaado inta lagu jiro magnetic resonance imaging:

• galkeeda ka soo gaaray effusion (jawaab ah xad-dhaaf ah si ay u dollar) ama peritendinoznoy bararka ee unugyada synovial (meelaha kuwa meesha xuub lahayn);
• adag ama khafiifinta ee seed ah;
• kala duwanaansho signal (la cudurada side aagga dhexe seed ogan longitudinally nuur, lagu gartaa signal hyperintensive on T1-VI);
• dillaac seed buuxa (diiwaan jajabkii seed adag leh oo signal doorsoon iyo dusha galgaloolan).

jab lafta

Qaar ka mid ah dhaawacyada ugu badan - a lafaha jabay in ay sameeyaan si wadajir ah jilibka. Haddii jab run arkay hoos u dhac toosan of signal la nasasho ah lafta cortical. Mararka qaarkood ku barakacay jajabkii. Waxaa laga yaabaa in hemarthrosis - dhiig galay saabka si wadajir ah. Waa on images T1-miisaamaa teedu signal sare marka loo eego dheecaanka nabarrada.

Gaar ahaan xusid mudan tahay chronic (dheer-taagan) dilaaca, sababta oo ah dadka qaar ka mid ah ka dib markii la helo dhaawac, ma ay doondoonaan gargaar xirfadeed. Waayo, dhaawacyo sida hypointense gartaa, isbedel nonuniform leh calaamado sclerosis unugyada buunshada iyo meel medullary.

Waxaa xusid mudan fiirsaneysa iyo dhaawac jug waxay (burbur) lafta. Waa maxay macnaha ay jilibka MRI xaaladaha kuwanu? In dhaawacyo dhacaan barar kooban intraosseous. Waxaa lagu gartaa waasac dambidhaafkiisu dhibic signal daciif on images iyo kordhinta ay xoogga on images T2-miisaamaa T1-miisaamaa. signal bahal ah lagu kaydin karaa 3-10 bilood.

Gebogebadii, waxa xusid mudan in si wadajir ah jilibka waa dhaawac intaa ka badan. Mid ka mid ah hababka ugu fiican ee cudurka of lesions kala duwan waa magnetic resonance imaging. Waxay leedahay faa'iidooyin dhowr ah. Marka hore, cilmi baaris waa mid aad wargelin ah. Waxa ay u ogolaataa xirfadlayaasha si ay u qiimeeyaan xaaladda oo ka mid ah lafaha iyo unugyada jilicsan. Marka labaad, resonance imaging ku magnetic waa dhib lahayn dadka bukaanka ah (ay ka maqan yihiin sababo). Tani waa sababta ugu MRI loo xilsaaray ee jilibka carruurta iyo dadka waaweyn.
