Color and power Doppler sonography of liver hemangiomas: a dream unfulfilled?
Neither color nor power Doppler imaging improved the capability of sonography for making a specific diagnosis of benign hepatic cavernous hemangioma.
The present data are consistent with our postulate that CHP and CAA report DNA damage by endogenous oxidants whose level correlates with metabolic activity. Because cumulative DNA damage by ROS generated via oxidative metabolism is considered the key mechanism responsible for cell ageing and senescence the data imply that these processes are delayed in G(0) quiescent lymphocytes or stem cells as compared with proliferating cells.
