Boxplot distribution of estimated signal-to-noise ratio (eSNR) for sequences performed using a combined rigid two-channel phased-array endorectal coil and an external phased-array coil (ERC-PAC) and external PAC only acquisition. Higher eSNR was observed for lesions for T2W (a, p < 0.0001), PZ for T2W (b, p < 0.013) and PZ for DWI (c, p < 0.01) when using ERC-PAC compared to PAC (shown below in boxplots). There was no difference in eSNR for lesions on DWI (d, p = 0.26)
