Figure 13f. Effects of MIP slab thickness on a coronal image of the abdomen. (a, b) Changing from the AIP technique (a) to the MIP technique (b) at a fixed slab thickness of 2.5 mm results in increased conspicuity of vessels. (c–f) More vessels are included per image as the section thickness increases to 5 mm (c), 10 mm (d), 15 mm (e), and 20 mm (f). However, use of thick slabs also results in obscuration of the vessels by other high-attenuation structures (bones, other vessels).
