Diagnostic value of 3.0T 1H MRS with choline-containing compounds ratio (∆CCC) in primary malignant hepatic tumors

Table 3 Receiver operating characteristic curve analysis among choline-containing compound ratio, junior radiologist and experienced radiologist

	AUC	95 % CI	P value
ΔCCC	0.98	0.94–1.00	0.01^a
Conventional MRI read by junior radiologist	0.78	0.62–0.93	0.10^b
Conventional MRI read by experienced radiologist	0.91	0.81–1.00	0.18^c

Note: ΔCCC choline-containing compounds peak area ratio, AUC area under the receiver operating characteristic curves, CI confidence interval
^a P value for ΔCCC VS conventional MRI read by junior radiologist
^b P value for conventional MRI read by junior radiologist VS conventional MRI read by experienced radiologist
^c P value for ΔCCC VS conventional MRI read by experienced radiologist
