Purpose: Quantitative ultrasound techniques have been recently shown to be capable of detecting cell death through studies conducted on in vitro and in vivomodels. This study investigates for the first time the potential of early detection of tumor cell death in response to clinical cancer therapy administration in patients using quantitative ultrasound spectroscopic methods. Experimental Desig...
Tumor response to neoadjuvant chemotherapy in patients (n=30) with locally advanced breast cancer (LABC) was examined using quantitative ultrasound. Three ultrasound backscatter parameters, the integrated backscatter coefficient (IBC), average scatterer diameter (ASD), and average acoustic concentration (AAC), were estimated from tumors prior to treatment and at four times during neoadjuvant ch...
We have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. The present experiment was undertaken to find out the best duration for treatment. A complete transverse fracture was made in the right radial bones of21 adult male rabbits by a Stanley knife. The animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental...
OBJECTIVE: To measure muscle temperature of ultrasound at 1-MHz and 3-MHz frequencies at a depth of 2.5 cm and to compare treatment durations for vigorous heating (increase of 4 degrees C) and for heating to 40 degrees C. DESIGN AND SETTING: A counterbalanced, repeated-measures design with 1 fixed, independent variable, 1.5-W/cm(2) ultrasound treatment (1 MHz, 3 MHz, or control [sham]) using a ...
BACKGROUND Low-intensity pulsed ultrasound and nonsteroidal anti-inflammatory drugs are used to treat ligament injuries; however, their individual and combined effects are not established. HYPOTHESES Low-intensity pulsed ultrasound accelerates ligament healing, a nonsteroidal anti-inflammatory drug delays healing, and the nonsteroidal anti-inflammatory drug inhibits the beneficial effect of l...

Biais and colleagues [1] have shown that echocardiographers can adequately perform a three-view cardiac examination in the emergency setting using a pocket ultrasound device (PUD). We have similarly noted that an evidencebased 'quick-look', cardiac limited ultrasound examination has diagnostic and prognostic value [2], can affect medical decision-making [3], and can be successfully taught to in...
Background and Objective: Ocular biometry refers to the measurement of the axial length of the eye and thickness of the intraocular structures. This process is routinely performed for all patients before cataract surgery. The accuracy of the biometric data is directly associated with the refractive status after cataract surgery. Currently, two methods of biometry, namely ultrasound and optical ...
