目的分析CT增强扫描和多平面重建(MPR)对胃腺癌CT术前T分期的临床应用诊断价值。方法胃腺癌患者133例,均经CT增强扫描及MPR对照检查,回顾性分析其临床和病理资料。结果MPR对胃腺癌术前T分期总检出率为78.9%(105/133),高于CT增强扫描的60.9%(81/133)(P<0.05)。常规CT对T1、T2期癌灶检出率较低。MPR对胃腺癌术前T3期的检出率高于常规CT(96.8%vs.61.3%)(P<0.01)。结论 CT增强扫描有助于胃腺癌术前T分期的评估。与常规CT比较,MPR可以提高胃腺癌,尤其对T3期胃腺癌的术前T分期检出率。
Objective To analyze the clinical value of CT enhanced scan and multiplanar reconstruction (MPR) in the diagnosis of gastric adenocarcinoma before T staging. Methods A total of 133 patients with gastric adenocarcinoma were examined by CT scanning and MPR. The clinical and pathological data were retrospectively analyzed. Results The overall positive rate of MPR in T staging of gastric adenocarcinoma was 78.9% (105/133), which was higher than that of CT scan (60.9%, 81/133) (P <0.05). Conventional CT on the T1, T2 lesion detection rate is low. The detection rate of preoperative T3 of gastric adenocarcinoma by MPR was higher than that of conventional CT (96.8% vs.61.3%) (P <0.01). Conclusion CT enhanced scan is helpful to evaluate the preoperative T stage of gastric adenocarcinoma. Compared with conventional CT, MPR can improve gastric adenocarcinoma, especially for T3 gastric adenocarcinoma preoperative T stage detection rate.
