Healthcare providers interested in acquiring MRI technology are finding it difficult to assess demand and, therefore, financial feasibility. This article presents a quantitative technique for MRI demand forecasting that interrelates the known applications of MRI to the specific clinical setting in which it is to be employed. The first step in this technique is to identify the number of patients with diagnoses for which MRI is known to be applicable. Next, each of these diagnoses is weighted according to the percent of patients who are expected to receive MRI scans versus other diagnostic modalities. Finally, the number of patients in each diagnosis is multiplied by the weighting to estimate the number of patients for whom MRI scans can be expected. This technique was used by a consortium of three major community hospitals in Omaha, Nebraska, as the basis of their demand forecasting and was used in successfully obtaining a Certificate of Need.
对购置磁共振成像（MRI）技术感兴趣的医疗服务提供者发现，很难评估需求，进而难以评估财务可行性。本文介绍了一种用于MRI需求预测的定量技术，该技术将MRI的已知应用与拟使用它的特定临床环境相互关联起来。该技术的第一步是确定已知MRI适用诊断的患者数量。接下来，根据预计接受MRI扫描的患者百分比与其他诊断方式的患者百分比，对这些诊断中的每一项进行加权。最后，将每个诊断中的患者数量乘以权重，以估计预计进行MRI扫描的患者数量。内布拉斯加州奥马哈市的三家主要社区医院组成的联盟使用了这种技术作为其需求预测的基础，并成功获得了需求证书。
