ICM-II: ABDOMEN, case 2

The upper left image shows injection into the celiac artery, which branches right after it takes off from the aorta into two main branches running relatively horizontally. What are those two main branches? The upper right image shows injection into the SMA, which has a relatively vertical course and many branches. The lower left images shows injection into the IMA, which also runs vertically but is much smaller and has fewer branches than the SMA.
