In
vivo angiography is often used in biomedical science. Ex vivo angiography of
excised organs or whole body is however rarely used due to the lack of
appropriate contrast solutions capable of entering and staying in the
vasculature after amputation or death. This study aims to develop contrast
solutions and methods for ex vivo MRA and CTA. Two solutions were produced
and used for MRA and CTA in four different species. MRA was found to have an
advantage to CTA in situations where blood vessels were in close proximity to
bones that can interfere with the signal in CTA.
