ABSTRACT
<p><b>OBJECTIVE</b>To investigate the diagnostic value of contrast-enhanced ultrasonography (CEUS) in preoperative Borrmann classification of gastric cancer.</p><p><b>METHODS</b>Asulfur hexafluonde-filled microbubble ultrasound contrast agent and continuous real-time imaging technique of contrast pulse sequencing were used. Two hundred and eighty-five patients with gastric cancer confirmed by biopsies who received preoperative CEUS examination were involved in this study. CEUS results were compared with postoperative pathological findings.</p><p><b>RESULTS</b>The accuracy rate of CEUS in determining the Borrmann classification of gastric cancer was 92.3%(263/285). The accuracy rates of BorrmannI(, II(, III(, IIII(, and IIIII( were 100%(12/12), 90.6%(77/85), 92.6%(126/136), 95.7%(45/47), and 60.0%(3/5) respectively.</p><p><b>CONCLUSION</b>CEUS is a useful diagnostic method for preoperative Borrmann classification of gastric cancer.</p>
