From: Prediction of poorly differentiated hepatocellular carcinoma using contrast computed tomography
CT findings | Sensitivity | Specificity | PPV | NPV | Accuracy |
|---|---|---|---|---|---|
All HCCs | Â | Â | Â | Â | Â |
Enhancement with non-enhanced area | 85% | 76% | 34% | 97% | 77% |
Tumor stain washout in the venous phase | 94% | 47% | 23% | 98% | 54% |
Both findings positive | 79% | 80% | 40% | 96% | 80% |
Small HCCs (3Â cm or less) | Â | Â | Â | Â | Â |
Enhancement with non-enhanced area | 75% | 90% | 48% | 97% | 88% |
Tumor stain washout in the venous phase | 100% | 55% | 22% | 100% | 60% |
Both findings positive | 75% | 92% | 55% | 97% | 90% |
