Detection of coronary artery stenosis with power Doppler imaging.
BACKGROUND Power Doppler is a new imaging method for detecting microbubbles during myocardial contrast echocardiography (MCE) based on the registration of variance resulting from ultrasound-induced nonlinear bubble behavior. We tested the hypothesis that power Doppler imaging can be used to quantify coronary stenoses. METHODS AND RESULTS Three left anterior descending (LAD) coronary stenoses ...
متن کاملNon-invasive estimation of cardiac wall stress by using tissue doppler-echocardiography ultrasound images: People with coronary artery stenosis
In this study, a method for non-invasive estimation of stress on the heart wall in the diastole phase is presented using ultrasound echocardiography and tissue Doppler imaging. The aim of this study was to evaluate the stress on the heart wall as a pre-diagnosis to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...
متن کاملA comparison of Power Doppler with conventional sonographic imaging for the evaluation of renal artery stenosis
BACKGROUND Power Doppler (PD) has improved diagnostic capabilities of vascular sonography, mainly because it is independent from the angle of insonation. We evaluated this technique in a prospective comparison with conventional imaging, consisting in Duplex and Color Doppler, for the evaluation of Renal Artery (RA) stenosis. METHODS Sensitivity, specificity and predictive values of PD and con...
متن کاملDetection of left main coronary artery stenosis by transesophageal color Doppler and two-dimensional echocardiography.
Although transthoracic two-dimensional echocardiography can detect dilation of the coronary arteries, the reliability of this technique in the detection of coronary artery stenosis is still doubtful. The purpose of this study was to test the ability of newly developed biplane transesophageal color Doppler and two-dimensional echocardiography in the detection of left main coronary artery stenosi...
متن کاملDoppler Sonography in the Detection of Significant Renal Artery Stenosis
Background Systemic hypertension is a major risk factor both for stroke and for myocardial infarction. The search for underlying treatable cause is a part of the management of a hypertensive patient. Renal vascular hypertension is the most common form of potentially curable hypertension and if untreated may terminate in renal failure. It has been estimated that 10% to 20% of new patients presen...
