Figure 6

a: The distal tip of a custom, MR-compatible active injection catheter (66) that was used for injections of 10% gadolinium with a tissue vital dye. b: ECG-gated, breath-hold long-axis image prior to injection. c: Long-axis image after first gadolinium injection mixed with a blue dye. d: Long-axis image after second gadolinium injection with green dye. Unfortunately, injection sites can only be appreciated for a short period of time due to wash-out of the gadolinium contrast agent. e: Postmortem image demonstrating distinct injection sites. Adapted from Karmarkar et al (66).
