CNR comparison of LEAs and contrast. CNR measures for 1000, 500, and 313 micron tubes for the various LEAs and iodine contrast. We also showed under our experimental conditions, the following confirmed by ANOVA test; Omnipaque 300 and NBCA have the highest contrast resolution, PHIL 25 has the lowest contrast resolution, Onyx 18 and 34 have higher contrast resolution compared to Squid 12 and 18, Onyx 18 and 34 have marginal differences in contrast resolution, Squid 12 and 18 have marginal differences in contrast resolution, and, overall poor contrast resolution at 313 micron during roadmap injections.

NBCA: nonradiopaque acrylic glue; CNR: contrast to noise ratio; LEA: liquid embolic agent; ANOVA: analysis of variance.
