Abstract
Electron beam tomography (EBT) may he compromised by rib artifacts. Two hun dred forty-seven abdominal studies were performed without (Group A, n = 222 ) or with (Group B. n = 25) the cone beam algorithm. One hundred eighty-six (83.8%) and nine (36%) studies of Groups A and B, respectively, displayed some level of artifact. In Groups A and B, major, minor, and no artifacts w ere found in 115 (51.5%) and 0 (0%), 71 (32.3%) and 9 (36%), and 36 (16.2%) and 16 (64%) patients, respectively (p < 0.01). The cone beam algorithm im proves EBT studies of the abdomen.
