Purpose The usefulness of Pneumo-esophageal 64-MDCT (PN-64CT) technique for characterization of esophageal cancer has been described and published. Our aim is to evaluate the usefulness of this technique for gastric cancer evaluation in correlation with surgical findings. Fig. References: M.

Methods and Materials Between May and September 2009, 10 patients (8 male and 2 female), mean age: 62 years, with gastric cancer diagnosed by biopsy were prospectively studied with PN-64CT before surgery. To achieve gastric distension, a 14F-Foley tube was introduced transorally and settled right below the cricopharyngeal muscles. Continuous CO2 airflow with an automated insufflator was supplied and sustained during the 64-MDCT acquisition. Multiplanar, 3D and virtual endoscopy reconstructions were performed.

Results Significant distension of the stomach including the gastro-esophageal transition zone was achieved in all patients allowing definition of both upper and lower borders of the tumors. The gastric lumen was visible in all its extension. 10/10 patients studied corresponded to adenocarcinomas. According to Borman classification 1/10 corresponded to type I, 2/10 type II and 2/10 type III and 5/10 type IV. The location of the tumors was: 3/10 major gastric curvature, 2/10 lesser gastric curvature, 2/10 pre-piloric, 1/10 cardias and 2/10 diffuse infiltration. PN-64CT accurately estimated total extent of cancer in all of the patients as well as proximal and distal extent. Fig. References: M.

Conclusion In this series, optimal distension allowed definition of both upper and lower borders of the tumors, useful for gastric cancer evaluation. It was accurate for the diagnosis and localization of longitudinal extent of gastric cancer. Fig. References: M.
