Power versus conventional color Doppler sonography: comparison in the depiction of normal intrarenal vasculature.

摘要: PURPOSE: To compare power Doppler sonography with color in the depiction of normal intrarenal vasculature. MATERIALS AND METHODS: Twenty kidneys 10 healthy, nonobese subjects were studied and at 3.5 MHz a pulse repetition frequency 800 Hz. The gain was increased until "noise" first became perceptible. standardize comparison, an ultrasound phantom scanned both techniques mean depth each kidney. RESULTS: Power demonstrated diffuse "blush" either entire or almost cortex 18 20 approximately half two other kidneys. Color did not depict cortical blush any In addition, subjective comparison showed that vasculature better than all CONCLUSION: superior to dem...
