Diagnostic ultrasound techniques used in the evaluation of the musculoskeletal system are rapidly evolving. Conventional B-mode and Doppler ultrasound imaging methods are workhorses in the diagnosis and treatment decision making for traumatic and pathologic conditions of joints, tendons, muscles, ligaments, and peripheral nerves. Recently developed sonoelastography techniques enable the qualita...

Ultrasound Imaging is primary modality in the diagnosis of many diseases. Compared to other imaging techniques ultrasound imaging owes its great popularity to the fact that it is safe and noninvasive procedure for visualizing the heart, vasculature, abdomen, fetal monitoring etc. Ultrasound images are degraded by intrinsic artifacts called speckle which is result of constructive and destructive...

As ultrasonic waves penetrate deep into tissues ultrasound imaging is able to image invisible things by “seeing through tissues” in real time. With the advent of ultrafast ultrasound imaging, the modality can reach thousands of frames per second, much faster than what the human eye can see. A completely new world is revealed as most important physiological processes in the human body occur in t...

twelve left camel forelimbs were collected, and ultrasonography was performed at five different levels around the metacarpal region. limbs were then cut in the transverse plane at levels corresponding to the ultrasound images. transverse and sagittal plane images were taken at each of the five levels, keeping all ultrasound imaging factors constant. echogenicity, diameter, width and cross secti...

Background & Aims: Today, different imaging techniques have been studied in the reading of radiationsensitive polymer gels dosage. Due to limitations of imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT), ultrasound techniques are proposed for dose-dependent parameter extraction. In this study, using MAGIC-f (methacrylic and ascorbic acid in gelatin initiat...

Previous work indicated that ultrasound echo decorrelation imaging can track and quantify changes in echo signals to predict thermal damage during in vitro radiofrequency ablation (RFA). In the in vivo studies reported here, the feasibility of using echo decorrelation imaging as a treatment monitoring tool was assessed. RFA was performed on normal swine liver (N = 5), and ultrasound ablation us...

ultrasound guidance for pain interventions is becoming increasing recognized as a useful imaging tool. one of the common interventions where it is gaining wider acceptance is during the performance of a stellate ganglion block. the following is a unique report where intravascular and neuronal injury occurred during the performance of an ultrasound guided stellate ganglion block followed by dysp...

OBJECTIVES To assess the diagnostic value of prenatal magnetic resonance imaging (MRI) in addition to prenatal ultrasound in a case of fetal varicella syndrome. METHODS Comparison of prenatal ultrasound and MRI features obtained at 26 and 32 weeks, respectively, with neonatal imaging (ultrasound, MRI and CT) and macroscopic and microscopic pathology findings in a fatal case of varicella embry...

Cardiac ultrasound plays an important role in the imaging of hearts in basic cardiovascular research and clinical examinations. 3D ultrasound imaging can provide the geometry or motion information of the heart. Especially, the wrapping of cardiac fiber orientations to the ultrasound volume could supply useful information on the stress distributions and electric action spreading. However, how to...
