64层螺旋CT结合多平面重建诊断早期胃癌的价值

Diagnostic value of early gastric cancer with 64 MDCT using transverse and multiplanar reconstruction images

目的探讨64层螺旋CT横断位结合多平面重建(MPR)对早期胃癌的检出价值。方法回顾性分析30例经病理证实的早期胃癌的CT影像特征,由2名有经验的放射诊断医师分别评估轴位及MPR重建图像对早期胃癌的检出率,意见不同时通过协商达成一致。结果 30例患者中,轴位图像检出18例,其检出率18/30;结合MPR图像检出26例,检出率26/30,两者之间的检出率差异有统计学意义(P=0.020);单纯CT横断位图像T分期准确性为26.67%(8/30),结合MPR图像T分期准确性为63%(19/30),两者比较差异有统计学意义(χ2=8.148,P=0.004)。结论 64层螺旋CT横断位结合MPR图像能提高早期胃癌的检出率及术前分期的准确性。

Objective To probe into the diagnostic value of transverse and muhiplanar reconstruction （MPR） with 64 MDCT in early gastric cancer. Methods Thirty cases of early gastric cancer confirmed by pathology underwent 64 MDCT ex- amination ,two experienced radiologists evaluated T staging on the transverse and MPR images in consensus. Results Early gastric cancer was detected in 26 of 30 （87%） patients with CT imaging combined with transverse and MPR and in 18 （60%） with single transverse imaging. Conclusion 64 MDCT using transverse and MPR provide a powerful tool for the early detec- tion and accurate preoperative staging of early gastric cancer.
