I would also like the title of the sub-plot that shows two series to end with "DLP and CTDIvol" rather than just "CTDIvol". Lastly, I would like the legend of the sub-plots to include either "DLP" or "CTDI" as appropriate. Are you able to help with any of the above? Regards, David – David May 13 '15 at 16:57

And if the scan length is identical, this could be used to compare doses.
Images were reconstructed with FBP and ADMIRE. The total CTDIvol values reported by Leng et al. were a mean of 515 mGy in a smaller sample size which were higher than both our full and reduced dose groups (349 and 202 mGy, respectively) . We acknowledge the differences in study design that make it difficult to further compare our study with the Leng et al. ( 14 ) study, who used a Kilic et al. used adaptive statistical iterative reconstruction (ASIR, GE Healthcare) technique and axial scan mode in 153 low-dose pediatric head CT (CTDIvol 20 ± 4 mGy for the cerebrum and 28 ± 4 mGy for posterior fossa) [ 10 ].

Distribution of CT dose index (CTDIvol), dose-length product (DLP) and effective dose (ED) were extracted from the data for single-phasic and multiphasic examinations. Results: The institutional DRL for our CT units were established as mean (50th percentile) of CTDIvol (mGy), DLP (mGy.cm) and ED (mSv) for single and multiphasic studies using the dose-tracking software.
