English: Maximum intensity projections representing a 3D reconstruction of magnetic resonance imaging to visualize contrast dye introduced intrarectally in a rhesus macaque exposed to a 1 ml inoculum. Gadofoveset trisodium contrast dye was administered intrarectally and 20 minutes later animals were returned to a recumbent position and MRI was performed. The 1 ml exposure shown here shows robust inoculum penetration including within the distal descending colon. Although background contrast was detected in the small intestines due to animal diet, contrast dye in the rectum and descending colon is clearly visible. This movie was selected to represent the 3 animals tested by MRI for luminal coverage following a 1 ml exposure.
