Correction to: J Headache Pain

After publication of the original article [1], the authors have notified us that an updated version of Figures 1, 2 and 3 should have been published. The incorrect and revised figures can be found below.

Incorrect figures:


Revised figures:

Fig. 1

Standard deviations of the intradural MMA measurements in the four analysis iterations. 7.0 T High Res: 7.0 T scan at full resolution; 7.0 T Low Res: 7.0 T scan resampled to 3.0 T resolution

Fig. 2

Change in intradural MMA circumference over time after each of the three interventions. 3.0 T and 7.0 T data is depicted as mean ± SE, all data analyzed with LAVA software

Fig. 3

Bland-Altmann plot depicting agreement between circumference measurements of intradural MMA 3.0 T vs 7.0 T within subject, within drug, within time point analyzed with LAVA software. Each point represents difference in circumference between 3.0 T and 7.0 T as a function of mean of the two measurements. Dashed lines are overall mean of differences ±2SD

The original article has been corrected.
