title: [Meniscal lesions].
abstract: The polymorphism and richness of arthrographic imaging and MRI of meniscal lesions require a perfect understanding of the anatomy of the menisci and the mechanisms of production of the lesions. Arthrography remains the reference diagnostic investigation with a good sensitivity and excellent spatial resolution. However, it is an invasive and operator-dependent technique. MRI of the knee, a non-invasive and independent method, allows the diagnosis of the majority of meniscal lesions. By using specific surface coils and appropriate sequences, MRI constitutes complete imaging technique allowing examination of all anatomical structures of the knee in all planes. Once MRI becomes more widely available, it should replace arthrography in the majority of clinical situations. The indications for arthrography will then be confined to contraindications of MRI.
