Deep vein thrombosis (DVT) has known morbidity and mortality. New noninvasive techniques such as B-mode scanning and Doppler ultrasonography (duplex) are highly accurate in the diagnosis of this problem but are relatively expensive and time consuming. Continuous-wave Doppler, a precursor noninvasive technique, is simple, cheap, and easy to perform at the patient's bedside. To test the effective...

Different ultrasound parameters have been used to assess endometrial receptivity during ART treatment, including endometrial thickness, endometrial pattern, endometrial volume, Doppler of uterine arteries and endometrial blood flow. However, conflicting results have been reported with regard to their role in the prediction of pregnancy in ART treatment. The 3D ultrasound with power Doppler prov...

In this paper, the Doppler shift of light is used to manipulate the change in optical path length using the classical interferometer. From which, the change in optical path length is related to the change in impact force, where finally the last of impact force can be related to the gel sheet absorption.

This review article discusses the use of laser Doppler imaging as a clinimetric tool to determine burn depth in patients presenting to hospital. Laser Doppler imaging is a very sensitive and specific tool to measure burn depth, easy to use, reliable and acceptable to the patient due to its quick and non-invasive nature. Improvements in validity, cost and reproducibility would improve its use in...

Background: To compare of two factors of Hemocysteine and Gherelin in IUGR and normal growth fetues. Materials and Methods: In this study, forthy fetuses were assessed for growth by ultrasound as IUGR with abnormal doppler and AGA fetus, Hemocysteine and Gherelin from cord blood were compared after delivery. Results: Two factors of Hemocysteine and Gherelin were increased in IUGR fetuses. Concl...

In the post genome-sequencing era, physiological phenotyping of genetically engineered mice is critical to further our understanding of the functional consequences of specific genetic defects. We have developed a 40-50 MHz ultrasound biomicroscopy-(UBM) guided, pulsed Doppler system for the sensitive detection of in vivo blood velocity waveforms in the mouse embryonic cardiovascular system. Our...

Doppler ultrasound is able to visualize blood flow by the change in frequency (Doppler shift) of sound waves that are reflected by moving blood cells inside the vessels (Doppler effect). Since hyperemia caused by vasodilation and angiogenesis can be the earliest detectable pathologic changes in the beginning of synovitis, Doppler ultrasonography can be used to assess inflammatory activity. In a...

Contrast-enhanced ultrasound and color doppler as guidance for transhepatic artery chemoembolization following three-dimensional conformal radiotherapy

We read with interest Dr. Hutchon's commentary on our recent review entitled " Enhanced Monitoring of the Preterm infant during Stabilization in the Delivery Room " (1). We would like to thank him for his kind comments. He raised a number of important points related to one aspect of our review, namely heart rate acquisition in the delivery room. He was disappointed by our " characterization of ...
