Abstract:
Objective To discuss the clinical application and value of dual-source spiral CT enhanced scan and multiplanar reformatting ( MPR) in the diagnosis of gastric cancer. Methods The 335 patients with gastric cancer who conducted dual-source spiral CT enhanced scan of upper abdomen under the hypotonic state before the definite pathological diagnosis were retrospectively analyzed,and had multi-di-mensional multiplanar reconstruction for the enhanced thin-section CT data by the multiplanar reformatting technique. Results Of 335 ca-ses,288 cases were detected by simple axial data,the detection rate was 86. 0%,320 cases were detected by MPR,the detection rate was 95. 5%,the differences were statistically significant (P<0. 05). The overall accuracy rate of Preoperative T staging by conventional axial and MPR images were 78. 3% and 89. 1% respectively, the difference was statistically significant. The overall accuracy rate of preoperative N staging by two methods were 73. 6% and 82. 3%,respectively,the difference was not significant. Conclusion Application of dual source spiral CT multiplanar reconstruction can significantly improve the detection rate of gastric cancer,and the average accuracy rate of preopera-tive TNM staging for gastric cancer is 84. 6%.
