Table 1 Imaging features of the managed lesions

From: Role of 18-FDG/PET in evaluation of hepatocellular carcinoma managed locally by transarterial chemoembolization compared to triphasic computed tomography

Imaging modality Managed lesion criteria Number of patients Percentage (%)
PET Increased tracer uptake 38 cases 82.6
No uptake (photopenic) 8 cases 17.4
CECT Contrast enhancement (arterial wash in and delayed wash out) 26 cases 56.5
Atypical contrast enhancement (marginal arterial enhancement with no washout or faint arterial enhancement) 6 cases 13
No contrast enhancement 14 cases 30.5
