The objective of our study was to determine the value of color Doppler imaging as an adjunct to gray-scale sonography to reveal the intra- or extraparotid origin of jugulodigastric nodules of uncertain location.Forty nodules in the jugulodigastric area from 38 patients were imaged with gray-scale, color, and power Doppler sonography. Nodules...

The aim of our study was to analyze changes in spectral Doppler waveforms between interlobar and interlobular arteries in renal transplants and to determine whether sampling location at interlobular level can be suitable for intrarenal resistive index (RI) measurements. Paired series of spectral tracings from interlobar arteries and respective...

Benign lymphoepithelial lesions are intraparotid nodules that develop as an early manifestation of HIV infection. The purpose of this study was to describe the spectrum of sonographic and Doppler findings of benign lymphoepithelial lesions in HIV-positive patients and to assess whether these findings are specific for the diagnosis of such...

To evaluate, with power Doppler (PD) ultrasound (US), the normal interlobular vasculature in patients who underwent renal transplantation and to assess if defects of the PD signal at the interlobular level correspond to cortical areas that lack blood perfusion at magnetic resonance (MR) imaging.Thirty-two normal and 33 malfunctioning...
