Three-dimensional drip infusion CT cholangiography in patients with suspected obstructive biliary disease: a retrospective analysis of feasibility and adverse reaction to contrast material.

Table 3 The bilirubin value, infusion time and final diagnosis in the nine cases where no secretion of contrast media was observed at DIC-CT.

The method by which the final diagnosis was made is indicated by the superscript numbers where 1 = laboratory findings, 2 = ultrasound, 3 = ultrasound with fine needle biopsy, 4 = MRCP, 5 = operation, 6 = ERCP and 7 = PTC.
