Abstract
OBJECTIVE:To evaluate the significance of plain and dual-phasic enhanced MDCT in the diagnosis of preoperative T staging of gastric carcinoma.
METHODS:MDCT examinations were performed on 57 patients with histopathologically confirmed gastric carcinoma. The scan protocol included plain scanning, arterial phase and portal phase scanning. The MPR image was reconstructed.
RESULTS:The MDCT had 78.94% of accuracy for diagnosing T stage, and 94.74%, 94.74%, 84.21% and 87.72% accuracy for T1, T2, T3, and T4, respectively. The sensitivity of the diagnosis were 25.00%, 80.00%, 78.26% and 88.00% for T1, T2, T3, and T4, respectively. The specificity of the diagnosis were 100%, 96.15%, 88.24% and 87.50% for T1 , T2, T3, and T4, respectively.
CONCLUSION:The plain scan and dual phase enhanced scans of MDCT, especially the thin slice and MPR reconstruction with proper windows technique, have clinical significance for diagnosing T staging of gastric carcinoma.
