摘要：

PURPOSE: To evaluate the ability of power Doppler ultrasonography to depict changes in renal perfusion after pharmacologic manipulations. MATERIALS AND METHODS: Six domestic swine were intubated and anesthetized. The right renal artery was catheterized for injection of epinephrine (100 mu g) and papaverine (2 mg/kg). Intraarterial blood pressure, heart rate, and oxygen saturation were measured continuously. Longitudinal images of the kidney were obtained, and the power Doppler color map was analyzed subjectively and by computer at baseline and at the time of maximum drug effect. RESULTS: Epinephrine produced vasoconstriction with a diminished power Doppler color map and a decrease in both subjective and computer scores. After papaverine-induced vasodilatation, the power Doppler map was enhanced, as reflected by increased subjective and computer scores. CONCLUSION: The power Doppler color map reflects anticipated changes in renal perfusion after alterations in blood flow by vasoactive drugs.
