Nigute wakoresha MRI kugirango ukomeretsa ivi mvunike kandi byoroshye?

MexiscUs ni fibrocartilage ya meniscus hamwe nigice cyambukiranya mpandeshatu giherereye hagati yigituba nigibaya, kigutezimbere cyane guhuza femoro-tibial kandi bigira uruhare runini mu mavi.

Ibisanzwe kandi bidasanzwe MRI

Ku mashusho ya Sagittal na Forma, Mixiscus isanzwe ni mpandeshatu muri hypointense. Ku ishusho yanyuma ya Sagittal, Meniscus ni 'umuheto ' inyubako igizwe nigice cya Sagittal cyahujwe nihembe ryimbere kandi inyuma (Ishusho 1).

Igishushanyo 1 MRI Usanzwe Kugaragara kwa Mentiscus. Ubucucike bwa Proton-buremereye bwa Sagittal Reba: Inguni yimbere kandi inyuma ya meniscal ni impengamiro ya homontenense. Mexiscus ni umuheto kandi ugizwe nigice cyigice cyo hagati gihuza amahembe yacyo imbere ni amahembe yinyuma inyuma.

Nibyiza kumva bimwe bidasanzwe anatomique nkuko bishobora kwigana imiti yisi:

• Mu gice cya SAGITTAL, Inzibacyuho hagati yisi yose kandi iri imbere;

• umukunzi wa poplitele sheath;

• Humphrey na Wisberg, Limoral Livol ihuza ihembe ryinyuma rya meniscle biganisha kuri femorral femoral;

• Liblique MentiscUsCuscuschus, rimwe na rimwe bihuza ihembe ryimbere rya meniscUs kuri ihembe ryinyuma rya Merieteri Imbere ya Merisiscus, irashobora kwigana Mentiscus cyangwa ikiganza cya Barrel

• Discid MenianCus ni ubumuga bwo kuvuka budasanzwe. Iyi dysplasia ya meiscal igira ingaruka hafi ya meniscus. Yayo 'isuzuma ' isuzuma kuri MRI rishingiye ku kubona amahembe y'imbere n'inyuma ku mashusho ya SAGITTAL byibuze ibice 3 bikurikirana (FIG. 2). Ibisubizo byahinduwe bishingiye kumiterere igice cyakoreshejwe.
