Improved detection of small insulinomas with intravenous dynamic CT.
OBJECTIVE
To evaluate the usefulness of intravenous dynamic CT in demonstrating angiographically negative insulinomas.


METHODS
Two patients with endocrinologic evidence of insulinoma were examined with intravenous bolus-dynamic CT.


RESULTS
Angiographically negative insulinomas as small as 5-7 mm were demonstrated unequivocally as enhancing nodules.


CONCLUSIONS
Intravenous dynamic CT using larger amounts of contrast material can improve detection of small (< 1.0 cm) insulinomas.
