Table 3 The reliability of the classification based on CT and MRI as well as MRI alone

From: OF spine classification of osteoporotic thoracolumbar vertebral body fractures by MRI and conventional radiographs only leads to high inter-observer agreement rates-an additional CT adds limited information for the of classification and the OF score
