Fractional moving blood volume: estimation with power Doppler US.

abstract：:Solid intrarenal neoplasms in children are usually Wilms tumors. Occasionally, however, a neuroblastoma appears to be intrarenal. In six cases where this phenomenon was observed, the histologic findings of each tumor were identical: undifferentiated neuroblastoma. In each case the child's condition rapidly and progres...
