Evaluation of the added value of precontrast phase for differentiating small HCC from AP shunt
Table 3 shows the diagnostic predictive values for both observers of each reading session.
Additional interpretation of precontrast phase enabled the two observers to correct several diagnostic errors made on the review of triphasic CT (Fig. 2).
- Eleven cases were overdiagnosed on triphasic CT by both observers,
and all these cases were corrected by additional review of precontrast phase with isoattenuation (Fig. 3).
- Five cases were underdiagnosed on triphasic CT by both observers,
two cases were correctly diagnosed by additional review of precontrast phase and the remaining three cases were uncorrected.
Both of the corrected lesions revealed hypoattenuation (Fig. 4).
Whereas all of three uncorrected lesions revealed isoattenuation on precontrast phase (Fig. 5).
