PDFAbstract
Objective To investigate the clinical value of hypotonic air-distended MSCT imaging in the evaluation of preoperative staging diagnosis for gastric cancer. Methods Prospectively studied 69 cases gastric cancer confirmed by clinical diagnosis, these patients were undergone hypotonic air-distended and dynamic contrast-enhanced MSCT scanning before operation. Collected the clinical and pathological dates of 21 cases confirmed by operation, To Analysis the correlation of CT preoperative stage and pathological stage. Results The T staging of hypotonic air-distended MSCT imaging was 80.9%, the N staging was 52.4%. Retrospectively studied the dates of 20 cases by waterdistended MSCT imaging, The T staging of water-distended MSCT imaging was 66.7%, the N staging was 50.8%. The results showed preoperative T staging accuracy rate for gastric cancer by hypotonic air-distended MSCT imaging better than water- distended MSCT imaging, but the preoperative N staging accuracy rate didn't improve significantly. Conclusion The preoperative T staging accuracy rate for gastric cancer by hypotonic airdistended MSCT imaging was better than water- distended MSCT imaging.
