title: The value of modern ultrasonographic techniques and computed tomography in detecting and staging of pancreatic carcinoma.
abstract: OBJECTIVE
  to assess the clinical value of ultrasonographic methods and computed tomography in diagnosing and staging pancreatic carcinoma.
  
  
  METHODS
  prospective clinical trial of 140 patients (64 women and 77 men; mean age 59,6) operated on for pancreatic carcinoma between 2000 and 2004. In each case helical CT, routine-, color- and power Doppler and 3-D USG were performed to detect and stage cancer. Analyses of accuracy, sensitivity, specificity, PPV and NPV of ultrasonographic methods and CT were made.
  
  
  RESULTS
  3-D USG showed the best accuracy of local staging (T): 95.6%. CT was the most accurate in lymph node assessment: 91.3%. The accuracy of CT, 3-D USG and power-Doppler at detecting vascular infiltration was 93.1%.
  
  
  CONCLUSIONS
  diagnostic accuracy of modern ultrasound techniques is comparable to helical CT in detecting and staging pancreatic carcinoma. USG is recommended due to the relatively low cost, non-invasiveness and availability of the procedure.
