Results of the ROC analysis.

**AUC-ROC > 0,80. *p < 0.005 in accordance with Bonferroni correction. ROC = receiver-operating-characteristic, AUC = area under the curve, CI = confidence interval, MRI = magnetic resonance imaging, TLCRR = tumor-to-liver count-rate ratio, MN = metanephrine, VMA = vanillylmandelic acid, A = adrenaline, NA = noradrenaline, HVA = homovanillic acid, DP = dopamine, NSE = neuron-specific enolase. Accuracy of several imaging parameters and tumor markers for prediction of unfavorable histopathology was tested by ROC analysis using Bonferroni correction for multiple comparisons. Corresponding AUC-ROC, p value and 95% CI are given.
