Doppler ultrasound for diagnosis of soft tissue sarcoma: efficacy of ultrasound-based screening score

Radiology and Oncology, 2015
Background. The utility of ultrasound imaging in the screening of soft-part tumours (SPTs) has been reported. We classified SPTs according to their blood flow pattern on Doppler ultrasound and re-evaluated the efficacy of this imaging modality as a ...

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

Animal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

Entheseal Doppler signals in ultrasound are associated with vasodilator drugs and age in patients with radiographic axial spondyloarthritis

Arthritis Research & Therapy
Background The ability of modern ultrasound machines to detect signs of enthesitis has increased, yet there is a lack of studies on patients with long-standing radiographic axial spondyloarthritis (r-axSpA).

Wireless blood pressure sensor implantation in sheep: A detailed technique

Animal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Transcutaneous measurement of volume blood flow [PDF]

Blood flow velocity measurements, using Doppler velocimeter, are described. The ability to measure blood velocity using ultrasound is derived from the Doppler effect; the change in frequency which occurs when sound is reflected or transmitted from a ...

Age and gender effects on echocardiographic and histopathological cardiac phenotypes in healthy adult mice

Animal Models and Experimental Medicine, EarlyView.
This study investigated the impact of age and sex on cardiac phenotypes in healthy adult C57BL/6J mice using echocardiography and histopathological analyses. Findings revealed that female mice demonstrated more pronounced global cardiac chamber dilation during aging.

Renal Power Doppler Ultrasonographic Evaluation of Children With Acute Pyelonephritis [PDF]

Acta Medica Iranica, 2011
Urinary tract infections are common in children. The available gold standard method for diagnosis, Tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation.

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]

, 2009
In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,
