title: [CT- and ultrasound-guided biopsies: prospective comparison of fine-needle aspiration with true-cut biopsy in 103 patients].
abstract: OBJECTIVE
  A prospective comparison of FNAB and TCB was performed in an identical set of patients and lesions.
  
  
  METHODS
  In 103 patients focal lesions were biopsied by US- or CT-guidance with at least one FNAB and TCB each. Complications were registered and documented. Cytological and histological specimens were evaluated independently. A final diagnosis was then attempted by consensus.
  
  
  RESULTS
  A total of 253 punctures was performed with sufficient tissue in 72.8% (FNAB) and 85.4% (TCB) of the cases. Diagnosis was possible in 68% (FNAB) and 80.6% (TCB). After combined evaluation of both specimens the diagnostic yield increased to 91.3%. Minor complications without clinical sequelae were observed in 21 patients.
  
  
  CONCLUSIONS
  A diagnostic strategy with the combined use of FNAB and TCB increases the diagnostic yield in image-guided punctures. Even though this approach needs at least two separate punctures, the complication rate does not increase.
