[MRI-guided transcutaneous aspiration biopsy of liver lesions].
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.
