To compare increased bone uptake of 99Tcm-MDP and magnetic resonance (MR) detected subchondral lesions, osteophytes, and cartilage defects in the knee in middle aged people with long-standing knee pain.
Fifty eight people (aged 41-58 years, mean 50) with chronic knee pain, with or without radiographic knee osteoarthritis, were examined with bone scintigraphy. The pattern and the grade of increased bone uptake was assessed. On the same day, a MR examination on a 1.0 T imager was performed. The presence and the grade of subchondral lesions, osteophytes, and cartilage defects were registered.
The kappa values describing the correlation between increased bone uptake and MR detected subchondral lesions varied between 0.79 and 0.49, and between increased bone uptake and MR detected osteophytes or cartilage defects the values were < 0.54. The kappa values describing the correlation between the grade of bone uptake and the grade of the different MR findings was < 0.57.
Good agreement was found between increased bone uptake and MR detected subchondral lesion. The agreement between increased bone uptake and osteophytes or cartilage defects was in general poor as well as the agreement between the grade of bone uptake and the grade of the MR findings.
比较99锝-亚甲基二膦酸盐（99Tcm-MDP）骨摄取增加与磁共振成像（MR）检测中年长期膝关节疼痛患者膝关节软骨下病变、骨赘和软骨缺损的情况。
对58例（年龄41 - 58岁，平均50岁）有或无膝关节影像学骨关节炎的慢性膝关节疼痛患者进行骨闪烁显像检查。评估骨摄取增加的模式和分级。同一天，在1.0T成像仪上进行MR检查。记录软骨下病变、骨赘和软骨缺损的存在情况及分级。
描述骨摄取增加与MR检测软骨下病变之间相关性的kappa值在0.79至0.49之间，骨摄取增加与MR检测骨赘或软骨缺损之间的kappa值<0.54。描述骨摄取分级与不同MR表现分级之间相关性的kappa值<0.57。
骨摄取增加与MR检测软骨下病变之间存在良好的一致性。骨摄取增加与骨赘或软骨缺损之间的一致性总体较差，骨摄取分级与MR表现分级之间的一致性也较差。
