Scatterplots show the positive linear relationships between median spinal level (ML) and total number of spinal levels (NL) of radiation therapy planned by using reference MR imaging protocol 4 compared with the more limited MR imaging protocols 1, 2, and 3. The Pearson correlation coefficient, r, and intraclass correlation (ICC) are both indicated for each comparison.
