Three-dimensional gradient-echo MR imaging of the knee: comparison with arthroscopy in 100 patients.

摘要: To compare the findings on magnetic resonance (MR) images of knee obtained with a three-dimensional gradient-echo (GRE) sequence at arthroscopy, menisci, cruciate ligaments, and hyaline cartilage were assessed in 100 patients. At MR imaging (performed by means fast steady-state precession) menisci (n = 200) areas 500) assigned grades zero (normal) to three (greatest abnormality). The ligaments considered intact, partially torn, or completely torn. sensitivity diagnosis meniscal tears seen arthroscopy was 97% specificity, 94%. For complete anterior ligament, 92% 96%. In posterior both specificity 100%. Good correlation existed between those assessment focal thinning full-thickness loss cartilage,...
