Purpose: The purpose of this study was to investigate the vascularity of primary gastric cancer lesions using color Doppler ultrasonography.
Methods: We used color Doppler ultrasonography to study 78 patients with gastric cancer detected on B-mode ultrasonographic examination and 14 patients without gastric tumors but with a slightly thickened gastric wall that was also detected on B-mode ultrasound. The color Doppler signals of the gastric lesions were graded as (-), no color signals; (+), slight increase in number of color signals; and (++), an obvious increase in number of color signals.
