Air trapping in heart-lung transplant recipients: variability of anatomic distribution and extent at sequential expiratory thin-section CT.

abstract：:Cystic hepatoblastomas share ultrasonographic characteristics with simple hepatic cysts; however, a distinction can be made by the demonstration of internal septations. The differentiation is important because cystic hepatoblastoma may have malignant potential. The ultrasonographic and scintigraphic findings in five c...
