BACKGROUND AND PURPOSE CCSVI was recently described in patients with MS. CCSVI is diagnosed noninvasively by Doppler sonography and invasively by catheter venography. We assessed the role of conventional MRV for the detection of IJV anomalies in patients with MS diagnosed with CCSVI and in healthy controls who underwent MRV and Doppler sonography examinations during 6 months. MATERIALS AND ME...

OBJECTIVE To assess the usefulness of colour power-Doppler transrectal sonography before/after contrast agent in the detection of local recurrence in patients with rising prostate-specific antigen values after radical prostatectomy and to compare with magnetic resonance imaging . MATERIALS AND METHODS 18 patients with rising prostate-specific antigen values after prostatectomy underwent digit...

We investigated the diagnostic potential of transcranial color-coded real-time sonography in 52 individuals using a phased-array ultrasound system with color-coded blood flow representation. Ultrasound scans in the axial and coronal planes were feasible through temporal acoustic bone windows in 49 subjects, enabling depiction of the main parenchymal and vascular structures as well as the ventri...

We compared digital intra-arterial angiography and transcranial Doppler sonography in acute cerebral ischemia as part of a wider study on a continuous series of 48 patients with acute focal cerebral ischemia in the carotid territory, observed within 4 hours of the onset of symptoms. The most significant Doppler findings of the middle cerebral artery included no detection of the artery when occl...

BACKGROUND AND PURPOSE Doppler sonography of the carotid arteries is routinely performed before catheter angiography, and its results may bias the subsequent interpretation of angiograms. We attempt to establish that Doppler sonography may show an exaggerated degree of carotid stenosis, introducing bias to the evaluation of carotid stenosis by subsequent catheter angiography. METHODS Angiogra...
