内容記述 | Purpose: To evaluatewhether the accuracy of local extension (T-staging) of esophageal carcinoma could be improved with addition of arterial phase images by use of multiYdetector row computed tomography. Materials and Methods: The institutional review board approved this study, and all the subjects provided informed consent. Dual-phase (the arterial and venous phases) contrast-enhanced computed tomography was performed in 45 consecutive patients (39 men and 6 women; age range, 47Y84 years) with 47 lesions of esophageal carcinoma who underwent surgical intervention. Two radiologists independently evaluated the T-staging of esophageal carcinoma on both phases. The Tstaging on both the arterial and venous phase images was compared with the T-staging at histologic evaluation by means of a resected specimen (as the reference standard). Differences in the overall accuracy and sensitivity for the T-staging between the 2 phases were analyzed with the McNemar test. Results: The analysis of the interobserver agreement for T-staging showed almost perfect agreement (J = 0.85 on the arterial phase and J = 0.93 on the venous phase). The overall accuracy in the arterial phase was significantly better than that in the venous phase (68% vs 51%, P < 0.01). The sensitivity values of the T-staging in the arterial phase were 0% in T1a, 71.4% in T1b, 12.5% in T2, 89.5% in T3, and 100% in T4. The sensitivity values in the venous phase were 0% in T1a, 14.3% in T1b, 0% in T2, 94.7% in T3, and 100% in T4. Statistical significance was apparent in the sensitivity of the T1b lesions. Conclusion: The arterial phase can improve the accuracy of T-staging of esophageal carcinomas, especially early-staged lesions. |
