Figure 3.
2D TSE T1WI of an SW480 tumor in the 15-mm-size tumor group (arrow). In the unenhanced scan, the tumor exhibits moderately high signal intensity relative to muscle (A). The conventional Gd-enhanced scan reveals mild enhancement of tumor (B). In the Mn-enhanced scan, the tumor displays marked enhancement along with a larger extent of the enhanced area (C). But both images demonstrate heterogeneous patterns of enhancement.
