title: Clinical value of (18)F-FDG PET/CT in postoperative monitoring for patients with colorectal carcinoma.
abstract: OBJECTIVE
  To evaluate the clinical value of (18)F-FDG PET/CT in postoperative monitoring for patients with colorectal carcinoma.
  
  
  METHODS
  66 postoperative patients with colorectal carcinoma underwent whole-body FDG PET/CT. The final histopathological and formal clinical follow-up findings were used as gold standard to determine the sensitivity and specificity of FDG PET/CT and enhanced CT of the same periods.
  
  
  RESULTS
  The sensitivity and specificity of FDG PET/CT in detecting recurrence are 96.30%, 94.87% (while enhanced CT are 70.37% and 87.18% respectively). The sensitivity and specificity in detecting metastasis are 95.35%, 82.61% (enhanced CT are 61.90%, 75.00%). SUVmax was significantly higher in malignant lesions [range 4.16-22.00, mean±standard deviation (x±s) 8.06±4.30] than in benign ones (range 1.18-6.25, x±s 2.82±1.02).
  
  
  CONCLUSIONS
  At present, whole-body (18)F-FDG PET/CT is an advanced diagnostic imaging technique in detecting loco-regional recurrence and metastasis in postoperative patients with colorectal carcinoma for its higher sensitivity and specificity.
