Abstract

AIM: To evaluate the efficacy of a new nuclear imaging Infecton (Tc-99m ciprofloxacin) for the diagnosis of acute cholecystitis.

METHODS: Sixteen patients thought to have acute cholecystitis were included in this study. The diagnosis of acute cholecystitis was made based on clinical symptoms and ultrasonographic and pathologic findings.

RESULTS: The 16 patients were composed of 12 acute and 4 chronic cholecystitis patients. Twelve patients with acute cholecystitis were image-positive, including one false-positive. Four patients with chronic cholecystitis were image-negative, of whom three were true-negative. This nuclear imaging had a sensitivity of 91.7%, a specificity of 75%, a positive-predictive value of 91.7%, and a negative-predictive value of 75%.

CONCLUSION: Tc-99m ciprofloxacin imaging is easy to perform and applicable for the diagnosis of acute cholecystitis.
