Diagnostic value analysis of 64 layers spiral CT for gastric carcinoma / 重庆医学

ABSTRACT

Objective To explore the diagnostic value of 64 layers spiral CT for gastric carcinoma .Methods The 87 patients (primarily diagnosed gastric carcinoma )were studied and scanned under 64 layers spiral CT including plain scans and enhanced scans respectively .The source images were reconstructed using the technique of multilane volume reconstruction (MPVR) and CT virtual endoscopy (CTVE) and conducting TNM stage ,then compared to histopathology results after surgery .Results 85 out of 87 patients with gastric carcinoma were diagnosed by CT .Detection rate of multi-detector CT(MDCT) for gastric cancer was 97 .7% , while the early stage and advanced stage gastric carcinoma were 66 .7% and 100% respectively .The accuracies of 64 layers spiral CT for the T stage ,the N stage and the M stage of the gastric carcinoma were 83 .9% ,72 .4% and 92 .0% respectively .Conclusion 64 layers spiral CT could be helpful for the diagnosis of gastric carcinoma and TNM stage .It might play great roles for the diag-nosis and treatment of gastric carcinoma .
