膝关节是人体最大、最复杂的关节,也是最容易受到损伤的关节之一。对于膝关节显性骨折及脱位,临床多以普通X线和CT检查为主,但两者对于无骨折线及骨皮质变形的骨挫伤诊断价值有限,且二者具有放射性危害。磁共振成像(magnetic resonance imaging,MRI)技术具有无创、无放射性危害,能对人体多方位直接成像,能清晰显示骨关节的解剖细节,且对骨髓病变敏感,MRI是目前广泛应用的骨挫伤检
The knee joint is the largest and most complex joint in the body and one of the most vulnerable joints. For the dominant fractures and dislocation of the knee, most of the clinical and X-ray and CT-based, but both for the diagnosis of bone contusion without fracture line and cortical bone contusion is limited, and both have radioactive hazards. Magnetic resonance imaging (MRI) technology has the advantages of noninvasive and non-radioactive, can directly image the human body in various directions, can clearly show the anatomical details of bone and joint, and is sensitive to bone marrow disease. MRI is the most widely used bone contusion
