CComparative transverse HR-MRI, US and UBM images of the canine eye at the level of the corona ciliaris. HR-MRI T2w, T1w, T1w post-contrast, US, UBM. The alternating long and short ciliary processes are delineated as radially oriented hypointense linear structures on a hyperintense background on T2w images, as slightly hyperintense relative to the background in T1w images and with moderate contrast enhancement in T1w post-contrast images, respectively. The ciliary processes are poorly delineated in US. UBM allows clear delineation of the long and short ciliary processes, but only in the dorsotemporal quadrant of the eye
