title: [MRI-guided transcutaneous aspiration biopsy of liver lesions].
abstract: OBJECTIVE
  To evaluate the clinical application of MR-guided aspiration biopsy of liver lesions.
  
  
  METHODS
  MR-guided aspiration biopsy of liver lesions with 0.5 T Conventional MR system and 19 gauge MRI-compatible aspiration needle was performed in 13 patients. For MR guidance, fast gradient echo sequence or fast spin echo sequence was used.
  
  
  RESULTS
  MR-guided aspiration liver biopsy was performed successfully without any complication on all patients. The accurate needle puncture rate was 100%, accurate diagnosis rate 92.3%, and false negative rate 7.7%.
  
  
  CONCLUSIONS
  MR-guided transcutaneous aspiration biopsy of liver lesions is a safe, accurate and effective method for diagnosis and differential diagnosis.
