three-dimensional color doppler ultrasonography is a new technique to evaluate the pattern of blood vessels. this study was performed to assess the feasibility of this method in evaluation of kidney vasculature pattern in dogs. in this paper, visualization of the renal, interlobar, arcuate, and interlobular arteries and veins using 3d color doppler ultrasonography in dogs is shown and the techn...

background: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...

Angiogenesis is a prominent feature of rheumatoid synovitis. Formation of new blood vessels permits a supply of nutrients and oxygen to the augmented inflammatory cell mass and so contributes to perpetuation of joint disease. Vascular endothelial growth factor (VEGF) is a potent endothelial cell-specific growth factor that is upregulated by proinflammatory cytokines and by hypoxia. Serum VEGF c...

Within the last decade, musculoskeletal ultrasonography is playing an increasingly important role in the evaluation and monitoring of patients with chronic infl ammatory arthritis. High-resolution musculoskeletal ultrasonography allows direct assessment of intra-articular and periarticular infl ammatory activity and structural damage in infl ammatory arthritis. There have been a growing number ...

results the mean age was 45.6 ± 13.1 (24 to 74 ) years. twenty-two were normal responders [considered as non-organic causes (37.3% of all patients)], 27 were classified as venous leakage, eight had arterial insufficiency and two were mixed type. maximum psv occurred before the fifth minute in 47 patients (92.2%). eight patients completed all phases of erection in the first 5 minutes. we defined...

Aneurism of the vein of Galen is a complex arteriovenous malformation which is of multiply communications between of the vein of Galen and the cerebral arteries. It represents less than 1% of the cerebral arteriovenous malformations. Few cases using three-dimensional (3D) power and color Doppler ultrasound have been reported in the literature. We present a case of an aneurysm of the vein of Gal...

results color doppler usg had a sensitivity of 95% and specificity of 98% in diagnosis of arterial injury. positive and negative predictive values of doppler usg were 92.5% and 94.2%, respectively. conclusions color doppler usg can be used as a reliable modality with acceptable sensitivity and specificity values to screen hemodynamically stable patients with limb trauma suspicious for arterial ...

BACKGROUND The clinical utility of ankle-brachial index (ABI) is not clear in subjects with less severe or calcified vessel. Therefore, we investigated the usefulness of color Doppler ultrasonography for diagnosing peripheral artery disease (PAD) in type 2 diabetes mellitus (T2DM) subjects. METHODS We analyzed 324 T2DM patients who concurrently underwent ABI and carotid intima-media thickness...

conclusion for more precise prediction of successful aavf maturation after spta, short-term follow-up doppler ultrasonography (< 2 weeks) was useful. if the asr was < 0.7 or if residual stenosis was ≥ 30%, immediate repeat spta is recommended. results the technical and clinical success rates were both 94.9% (56/59); the mean asr was 0.84. an asr of ≥ 0.7 and no significant residual stenosis (< ...

background: stroke is a multifactorial disorder, the most common cause being arterial occlusion. transcranial doppler ultrasonography (tcd) is a common non-invasive method available for assessment the arterial blood flow of the brain. objective: assessment the hemodynamic parameters of cerebral arteries, using tcd device in patients suffering ischemic stroke. materials and methods: this descrip...
