title: [Analysis of 22 cases of CT-guided puncture biopsy for chest tumors].
abstract: OBJECTIVE
  To evaluate the application of CT-guided puncture biopsy for diagnoses of tumorschest.
  
  
  METHODS
  Twenty-two patients with thoracic tumors that were not pathologically identified received CT-guided puncture biopsy for histological and cytological examination.
  
  
  RESULTS
  All biopsy procedures were successfully completed and 18 cases were identified as having malignant tumors by histological examinations, while 5 identified by cytological examinations, and definite pathological diagnoses were established in 19 cases.
