Background: We investigated the vascularity of advanced gastric adenocarcinomas by using percutaneous power Doppler imaging. Methods: Seventeen patients with gastric cancer and 10 without a gastric tumor, but with a slightly thick gastric wall in the B‐mode ultrasound, were investigated with the use of power Doppler imaging. The color signals of the gastric lesion were graded as follows: 1, no color signals or the same as the surroundings; 2, color signals were slightly increasing; and 3, color signals were obviously increasing. Results: The color signals of three patients were graded 1, those of eight patients were graded 2 and those of six patients were graded 3 in the gastric cancer group. The color signals of all 10 patients without a gastric tumor were grade 1. This difference was statistically significant ( P = 0.0002). Conclusions: Power Doppler imaging showed vascularity of gastric cancer increasing in the majority of patients (14 of 17: 82%). Thus, power Doppler imaging might be a good screening examination method for gastric cancer.
