T e incorporation of color Doppler systems on trans\'aginal probes has made it possible to evaluate the normally occurring cyclical haemodynamic changes in the I"male pelvis. In addition to the depiction of major \ascularchannels, small intraparenchymal vessels within the uterus and ovaries can be easily demonstrated. While color flo\\ imaging improves the ability to demonstrate \ascular struct...

The carotid color Doppler ultrasound is usually the first imaging modality employed for the assessment of patients with cerebrovascular symptoms. The recognition of the distal stenoocclusive flow pattern is key for the detection of spontaneous dissection of the internal carotid and vertebral arteries in young patients who present cerebral ischaemic signs. We present six cases of patients whose ...

A 66-year-old male presented with an angiographically occult orbital varix. Angiography and phlebography failed to demonstrate the lesion. Computed tomography angiography showed the varix, but not the vascular flow. Color Doppler flow imaging clearly demonstrated the well-defined varix with slow flow velocity, as well as the precise anatomical location. We recommend color Doppler flow imaging a...

Objective: To evaluate the adnexal masses with conventional gray scale and color Doppler flow imaging and to assess their diagnostic reliability to differentiate benign and malignant adnexal masses. Materials and methods: We evaluated 30 patients with adnexal mass. Morphological characterization of the mass was done using Sassone score. Color Doppler parameters noted down in each patient and Ca...

Doubly committed subarterial (supracristal) Residual VSD (by color and pulsed-wave Doppler and with contrast), although small leaks are acceptable at the borders of the patch. Residual or new aortic insufficiency compared with prebypass findings. RVOT obstruction or pulmonary regurgitation. Minimal PI may be acceptable. Muscular, Apical, Inlet Residual VSD (by color and pulsed-wave Doppler and ...

Aim & Objectives: To evaluate the cause of stroke and to compare accuracies of both Color Doppler & MRA in stroke patients. To delineate pitfalls during imaging, interpretations and limitations of Color Doppler ultrasound. Materials & Methods: This study was carried out in 50 patients who had presented with symptoms of strokes at Krishna institute of medical sciences, Karad from August 2013 to ...

treatment of stenoses by percutaneous intervention has been shown to increase the longevity of the dialysis shunts (1, 2). In current clinical practice, detection and grading of the stenosis are usually performed using color doppler sonography and digital subtraction angiography (DSA) (3, 4). Color doppler sonography is obviously the first choice of diagnostic method and it can non-invasively d...

Background The inflow propagation velocity (Vprop) of the early filling wave has been proposed as an accurate marker of left ventricular (LV) diastolic function [1]. Traditionally, Color M-mode echo Doppler is used for Vprop-assessment. However, this method has not been validated against an alternative modality such as velocity-encoded (VE) MRI for assessing Vprop. The purpose of this study was...

OBJECTIVES The purpose of this study was to assess the clinical feasibility of three-dimensional (3D) reconstruction of color Doppler signals in patients with mitral regurgitation. BACKGROUND Two-dimensional (2D) color Doppler has limited value in visualizing and quantifying asymmetric mitral regurgitation. Clinical studies on 3D reconstruction of Doppler signals in original color coding have...

OBJECTIVES We tested the feasibility of using analysis of color kinesis images to objectively assess global and regional left ventricular (LV) diastolic function in patients with dilated cardiomyopathy (DCM). In addition, the ability of this technique to track drug-induced changes on LV diastolic properties was studied. BACKGROUND Diastolic dysfunction contributes to symptomatology in patient...
