Sensitivity and Specificity in Detection of Liver Metastases

Lesion group and modality	Sensitivity (%)	Specificity (%)
All lesions
PET/CT	76^*	90
Gd-EOB-DTPA–enhanced MRI	91	100
PET/MRI^†	93/93	87/97
Lesions ≤ 1 cm in diameter
PET/CT	30	86
Gd-EOB-DTPA–enhanced MRI	80	100
PET/MRI^†	70/70	71/100
Lesions > 1 cm in diameter
PET/CT	87	94
Gd-EOB-DTPA–enhanced MRI	93	100
PET/MRI^†	98/98	100/94

↵* Difference in sensitivity was significant (P < 0.05) between PET/CT and PET/MRI when all liver metastases were considered.
↵† Values are for reader 1/reader 2, respectively.
