1 Optimizing diffusion-weighted magnetic resonance imaging for evaluation of lung tumors: A comparison of respiratory triggered and free breathing techniques  Signe Swerkersson, Oscar Grundberg, Karl Kölbeck, Andreas Carlberg, Sven Nyrén, Mikael Skorpil  European Journal of Radiology Open  Volume 5, Pages (January 2018) DOI: /j.ejro Copyright © 2018 The Authors Terms and Conditions

2 Fig. 1 Respiratory-triggered (A, B) and free breathing (C, D) axial diffusion weighted images (b = 750 s/mm2) of a tumor in the right lung without and with a region of interest. The respiratory-triggered acquisition time was approximately 9 min and the free breathing acquisition time was 2:26 min.

3 Fig. 2 Bland-Altman plots show reproducibility of ADC measurement for Reader 1 (A, C) and Reader 2 (B, D) with repeated free-breathing (A, B) and respiratory-triggered (C, D) imaging. X-axes show means of ADCs measured on the first and second acquisition, and y-axes show differences between ADCs on each set as a percentage of their mean. Dashed lines = 95% limits of agreement.
