PET-CT vs MRI in detecting liver
lesions
•
On a per-lesion basis, PETCT and MRI were
discordant in 15% (10/66 scans).
•
MRI correctly identified more sub-centimetre
metastases in eight scans.
•
PETCT correctly identified more metastases
in one case and confirmed disease in one
equivocal MRI. Kong et al 2008
•
lesion detection reduces below 1 to 1.5 cm
