Added value of hepatobiliary phase gadoxetic acid-enhanced MRI for diagnosing hepatocellular carcinoma in high-risk patients

Table 4 Sensitivity, specificity, and positive and negative predictive values for diagnosing hepatocellular carcinoma using conventional dynamic magnetic resonance imaging or conventional dynamic magnetic resonance imaging with hepatobiliary phase images

	Conventional dynamic MRI	95%CI	Conventional dynamic MRI+HBP	95%CI
Sensitivity	79.7%	67.2-89.0	93.2%	83.5-98.1
Specificity	97.8%	85.5-99.9	97.8%	88.5-99.9
Positive predictive value	97.9%	88.9-99.9	98.2%	90.4-100.0
Negative predictive value	78.9%	66.1-88.6	91.8%	80.4-97.7

MRI: Magnetic resonance imaging; HBP: Hepatobiliary phase.
