An Assessment of the Intra- and Inter-reliability of the Lumbar Paraspinal Muscle Parameters Using CT Scan and Magnetic Resonance Imaging

Abstract

The reliabilities of the CT scan and MRI for measuring the FCSA and fatty infiltration of the atrophied lumbar paraspinal muscles were acceptable. It was reliable for using uniform one image method for a single paraspinal muscle evaluation study. And the authors preferred to advise the MRI other than CT scan for paraspinal muscles measurements of FCSA and fatty infiltration.
