Data presented as correlation coefficient (r) with 95% confidence interval achieved by bootstrapping.

n total, the total number who underwent both PHHE and reference imaging; n pathology, total number with the described pathology.

^aContinuous variable, analysed by Pearson's correlation, all others analysed by Spearman's rank correlation.
