• To study the usefulness of three-dimensional spiral CT (3DCT) in the diagnosis of advanced gastric cancer (AGC). Between June 1999 and December 2000, 54 patients with AGC were consecutively examined. On the 3D Virtuoso workstation, source images were uploaded to create a 3DCT volume block that was then processed with volume rendering technology (VA30C) to achieve virtual-reality endoscopy (VE), clipped volume block (CVB), and ray sum (RS). After the above scanning, all the patients were examined by a two-phase enhanced spiral CT (2DCT). The visualization, manifestation, and Borrman's classification of lesions in VE, CVB, RS, and 2DCT were evaluated and correlated with gastroscopic, surgical, and pathological findings. Respiratory artifact and gastric residue were also observed. (1) CVB showed the excellent visualization in 88.9% of cases, in contrast to VE and RS (50.0% and 38.9%) (P < 0.01). (2) The accuracy in evaluating mucous membrane, ulceration, lumen, wall, cardia, pylorus, and extension of the tumor w
