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...

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...

OBJECTIVE The purpose of this study was to review the literature concerning upper extremity deep venous thrombosis (UEDVT) diagnosed by color Doppler duplex sonography (CDDS) in cancer patients with indwelling central venous catheters (CVCs). METHODS From computerized databases (MEDLINE and Ovid), relevant publications regarding CDDS of the upper limb veins in cancer patients with CVCs were r...

1695 he central focus of carotid Doppler sonography studies is the detection and characterization of atherosclerotic disease and stenosis. Doppler sonography samples are used primarily to quantify velocity elevations at sites of stenosis. However, more subtle clues to disease are contained in the shape and contour of the Doppler sonography waveform itself. Aberrations of waveform morphology can...

We describe the use of serial transcranial Doppler studies to evaluate neurovascular disease in three girls presenting with acute stroke due to primary cerebral vasculitis (n = 2) and West Nile vasculitis (n = 1). Correlation of abnormal findings on transcranial Doppler sonography was compared with those of MR angiography and conventional angiography in each child. All three girls had left midd...

BACKGROUND The aim of this study was to assess differences in intrarenal artery Doppler parameters measured without and with Doppler angle correction. METHODS We retrospectively reviewed color duplex sonography in 30 normally functioning kidneys (20 native kidneys in 10 subjects and 10 transplanted kidneys in 10 subjects) performed between January 26, 2010 and July 26, 2010. There were 10 age...

ndometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity . the aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness in uterine receptivity in infertile women treated with assisted reproductive technologies (art). a...

PURPOSE The purpose of this preliminary study was to evaluate the usefulness of power Doppler sonography in differentiating metastatic from nonmetastatic cervical lymph nodes in patients with cancer. METHODS Histologically proved metastatic (n = 71) and nonmetastatic (n = 220) lymph nodes were examined with power Doppler sonography in 77 patients with head and neck cancer. Power Doppler sonog...

BACKGROUND AND PURPOSE Digital subtraction angiography is the reference standard technique to evaluate intracranial vascular anatomy and used on the endovascular treatment of vascular diseases. A dedicated optical flow-based algorithm was applied to DSA to measure arterial flow. The first quantification results of internal carotid artery flow validated with Doppler sonography are reported. MA...
