Ultrasound-guided percutaneous core needle biopsy of abdominal subcutaneous fat for diagnosing amyloidosis: comparison with bone marrow biopsy.

The sensitivity of amyloid deposition was significantly higher with USPCB of abdominal subcutaneous fat than BMB. Acquiring more cores by multiple biopsies instead of using a larger bore needle and thin subcutaneous fat pad may be a favorable factor for the diagnostic accuracy of USPCB.
