CT had higher locational and qualitative rate than B-mode Ultra-sound. CT定位定性准确率高于B超。
LAVA technology has more diagnostic value in the preoperative diagnostic than enhanced T1WI, can significantly improve the detection rate and qualitative rate of lesions. LAVA技术较常规增强扫描在术前诊断方面具有重要价值,能显著提高病灶的检出率及定性率(QR)。
The qualitative diagnostic rate of CT for tumors was 81.8 % which is superior to other methods. CT对肿瘤的定性诊断率81.8%,优于其他方法;
The qualitative identification rate reaches 100 %, the quantitative detection rate reaches 97.19 %. 定性识别的准确率达100%,定量检测的准确率达97.19%。
Results : The detectable rate was 98 %, the locative accurate rate was 92.1 % and the qualitative coincidence rate was 78. 2 % in middle-late stage of colorectal cancer with ultrasound. 结果:超声对中晚期结直肠癌检出率为98%,定位准确率92.1%,定性符合率78.2%。
