Figure 2. Computed tomographic scans show (A) the needle tip (arrow) cephalad to the celiac artery, (B) the preaortic bilateral contrast spread cephalad to the celiac artery, and (C) the preaortic bilateral contrast spread caudad to the celiac artery. This pattern is consistent with four quadrants with contrast (quadrants 1, 2, 3, and 4 of Figure 3).
