| Abstract: | The objective of our study was to determine the correlation between gallbladder opacification by delayed CT and contrast-associated nephropathy (CAN). Delayed CT after angiography was performed in 269 patients. Gallbladder opacification was defined when the CT value in gallbladder was more than 30 HU. Positive renal dysfunction was recognized as CAN which defined as an increase in serum creatinine level > 0.3 mg/dl and > 20 % on days 1, 3, or 7. Gallbladder opacification appeared in 154 of 269 (57 %) patients and CAN in 35 (13 %) patients. Of 117 patients without gallbladder opacification, 17 CAN (14 %) were recognized, and of 152 patients with gallbladder opacification, 18 CAN (12 %) were recognized. No significant correlation existed between delayed gallbladder opacification and CAN. Received 20 August 1996; Revision received 19 December 1996; Accepted 27 January 1997 |
