For the dedicated athlete in whom minor injuries are frequent and major injuries relatively common, a noninvasive knee assessment could either obviate the need for arthroscopy or focus its direction. The opportunity to study asymptomatic athletes was not feasible before the advent of magnetic resonance imaging (MRI). In this preliminary work, we examined 40 knees in 20 asymptomatic volunteer athletes, including five professional basketball players and 15 collegiate football players. Images were obtained at 0.5 T or 1.5 T. Spin echo sequences were used to obtain 5.0 mm thick coronal and sagittal sections. Fifty percent of asymptomatic athletes (10/20) had significant baseline MRI abnormalities that could have adversely affected scan interpretation in the context of an acute injury. Half of these athletes with MRI abnormalities, or 25% of the total (5/20), had no previous surgery and were unaware of significant injury.
对于那些经常受轻伤且相对容易受重伤的职业运动员来说，无创膝关节评估要么可以避免关节镜检查的必要性，要么可以确定关节镜检查的重点。在磁共振成像（MRI）出现之前，对无症状运动员进行研究是不可行的。在这项初步研究中，我们检查了20名无症状志愿者运动员的40个膝关节，其中包括5名职业篮球运动员和15名大学橄榄球运动员。图像在0.5T或1.5T磁场下获取。使用自旋回波序列获得5.0毫米厚的冠状面和矢状面图像。50%的无症状运动员（10/20）存在明显的基线MRI异常，这些异常在急性损伤的情况下可能会对扫描结果的解读产生不利影响。这些有MRI异常的运动员中，一半（即总数的25%，5/20）此前没有接受过手术，也不知道自己受过重伤。
