title: [Effectiveness of preoperative diagnosis in scintigraphically cold thyroid nodule].
abstract: OBJECTIVE
  To compare the diagnostic efficacy of different imaging procedures carried out in patients with scintigraphically cold thyroid nodules.
  
  
  METHODS
  The preoperative imaging procedures carried out in all patients operated on for cold thyroid lesions at the Department of Surgery of the University of Cologne were recorded in prospective manner for 1 year. Special attention was paid to the difference between in-patient and out-patient management. Diagnostic accuracy was assessed by comparison with the intraoperative findings and histology.
  
  
  RESULTS
  The combination of ultrasonography and fine needle aspiration cytology proved effective. Computed tomography should be reserved for the preoperative assessment of large thyroid tumors. Repeat examinations seldom gave additional information.
  
  
  CONCLUSIONS
  Standardized preoperative investigations may be performed on an out-patient basis, provided attention is paid to quality assurance.
