Prevalence of thyroid dysfunction and effect of contrast medium on thyroid metabolism in cardiac patients undergoing coronary angiography
Background Iodinated contrast media (CM) may influence thyroid function. Precautions are generally taken in patients with hyperthyroidism, even if subclinical, whereas the risks in patients withExpand

In Vivo Radiofrequency‐Based Ultrasonic Tissue Characterization of the Atherosclerotic Plaque
Background and Purpose The ultrasonic image can offer unique information on the composition of atherosclerotic plaque, ie, the relative content of lipids, fibrous tissue, and calcific deposits. ToExpand

Quantitative assessment of ultrasonic myocardial reflectivity in hypertrophic cardiomyopathy.
The purpose of this study was to investigate the relation between acoustic properties of the myocardium and magnitude of left ventricular hypertrophy in patients with hypertrophic cardiomyopathy. AnExpand

The use of frequency histograms of ultrasonic backscatter amplitudes for detection of atherosclerosis in vitro.
This study was designed to determine whether a quantitative analysis of integrated backscatter amplitude distribution is potentially useful in characterizing the atherosclerotic lesion. One hundredExpand

On-line evaluation of ultrasonic integrated backscatter.
Although it is already known that reflected ultrasonic signals (backscatter) are changed by the structure of the tissue through which they pass, clinicians are still awaiting a practical instrumentExpand

Normal ultrasonic myocardial reflectivity in hypertensive patients. A tissue characterization study.
Ultrasonic backscatter of myocardial walls is directly related to the morphometrically evaluated collagen content in humans. The integrated backscatter is also increased in hypertrophicExpand

In vivo radiofrequency ultrasound analysis of normal human heart structures
Twenty young subjects were studied with microprocessor system for quantitative analysis of backscattered radiofrequency (RF) signals from normal heart structures. This system allows an “on line”Expand

Regression of hypertensive myocardial hypertrophy does not affect ultrasonic myocardial reflectivity: a tissue characterization study
Objective Ultrasonic backscatter from the myocardial walls is directly related to the morphometrically or biochemically evaluated collagen content in man, and shows a normal pattern of quantitativelyExpand

On-line two-dimensional evaluation of ultrasonic integrated backscatter.
We describe an apparatus for the on-line evaluation of integrated backscatter from areas of tissue. The equipment is fully integrated into a B-mode ultrasonic system; there are therefore no newExpand

Quantitative aspects in myocardial contrast echocardiography.
Myocardial tissue perfusion is not currently quantified in the clinical setting. Thus the aim of this paper is to review the quantitative information on myocardial perfusion provided by contrastExpand
