OBJECTIVE. The purpose of our study was to determine the utility of dual-phase MDCT with 3D reconstruction in the staging and resectability of gallbladder carcinoma.

SUBJECTS AND METHODS. Twenty-seven consecutive patients with suspected gallbladder carcinoma on clinical examination and routine sonography were prospectively analyzed with dual-phase MDCT. Of these patients, only 20 who underwent a laparotomy for extended cholecystectomy or a palliative surgery were included in the study. Three-dimensional volume-rendered reconstruction was used for evaluation of the vascular invasion and anatomy. The staging and resectability as determined on CT were compared with preoperative findings.

RESULTS. On the basis of the CT findings, eight tumors were resectable and 12 were unresectable. On surgery, 11 tumors were found to be resectable and the remaining were unresectable. Overstaging …
