Figure 2

A configuration of the Z-frame, which has been used in our clinical trial [4]. The Z-frame has seven rigid tubes with 7.5 mm inner diameters and 30 mm length filled with a contrast agent (MR Spots, Beekley, Bristol, CT) placed on three adjacent faces of a 60 mm cube, thus forming a Z-shaped enhancement in the images.
