  1. Fine needle biopsy guided by either contrast-enhanced harmonic or conventional endoscopic ultrasound, with macroscopic on-site evaluation of specimen adequacy, achieves similarly low false-negative rates and high diagnostic accuracies when the prevalence of avascular areas in lesions is <31%.
  2. Routine use of contrast-enhanced harmonic endoscopic ultrasound for fine needle biopsy may be unnecessary when dedicated needles are used for tissue acquisition and the expected prevalence of avascular areas is low in target lesions.
