摘　　要：目的:探讨磁共振腕关节扫描时两种不同体位的应用。方法:38例腕关节扫描患者分别采用俯卧肢体上举位及仰卧自然放置位进行3.0T磁共振扫描,扫描序列包括:横轴位、冠状位和矢状位的FS-PDWI,横轴位和冠状位的TSE-T1WI序列,分析两种体位的检查成功率及图像质量。结果:较年轻、活动便利且身材较胖者采用俯卧肢体上举位较佳;年龄大、活动不方便或身材偏瘦者更适于采用仰卧自然放置位。结论:腕关节磁共振扫描时应根据患者实际情况采取不同扫描体位,使患者能耐受检查,为影像诊断提供有价值的图像。Objective：To investigate the position of patients when their wrist joints were examined by 3.0T MR scanner.Methods：Thirty-eight cases received wrist joint MRI examinations were performed with prone arm upward position or supine arm sideway position.The axial and coronal plans were scanned by FS-PDWI and TSE-T1 WI sequence,the sagittal plan were scanned only by FS-PDWI sequence.3.0T MR scanner was used for every patient.The success rate and image quality were compared between two positions.Results：The prone arm upward position was suitable for the young,fat or those flexible to move.The supine arm sideway position,however,was more suitable for the older,lean or those inconvenient to move.Conclusion：The position for wrist joint MRI examination should be chosen based on the condition of patients and in favor of tolerance and image quality.
