"Diffusion of Innovation" is a marketing theory that predicts the pattern of adoption of new products, with specific characteristics of the product determining the rate of adoption. This article attempts to determine whether MRI fits the predicted pattern. A computer Medline search to assess the number of articles printed on MRI shows that MRI is being adopted more slowly than CT, but like CT, MRI is following the pattern predicted by the Diffusion Theory.
“创新扩散”是一种营销理论，它预测新产品的采用模式，产品的特定特征决定采用率。本文试图确定磁共振成像（MRI）是否符合预测模式。一项通过计算机检索医学文献数据库（Medline）来评估关于MRI的文章发表数量的研究表明，MRI的采用速度比计算机断层扫描（CT）慢，但与CT一样，MRI正遵循创新扩散理论所预测的模式。
