Figure 4

Temporally acquired 10 post-contrast L-L T 1 WIs obtained over about 25 min following a step-down infusion of Gd-DTPA. The images demonstrate a region of enhancement that increased in size and signal intensity over the first 4–5 scans before reaching a relatively steady state. The color scale bar on top represents lowest to highest values in arbitrary units from left to right (black to white). Note the persistent white- and red-tinged pixels suggestive of greater magnitude of leakage in the center of the enhancing region representing the probable source of leakage.
