Atrial septal defects (ASDs) are one of the most common congenital heart defects, accounting for between 6-10% of congenital heart disease in humans (Silvestry et al., 2015). Secundum defects are the most common type of ASD in both humans and canines. In canines, some breeds (particularly Boxers) more susceptible than others, although the true incidence [...]
Stress echocardiography is a safe, noninvasive and relatively cost-effective way to assess for coronary artery disease, stenosis severity and contractile reserve in particular subgroups of patients. Stress echo can refer to TTE performed during exercise or phamacological stress. The major indications for stress echo in humans are discussed in the following article.
How to assess the aortic valve with echocardiography Aortic valve disease can have a range of aetiologies, including: Congenital: - Unicuspid, quadricuspid or bicuspid aortic valve. The first two are usually discovered in infancy, but a bicuspid valve may remain asymptomatic for many decades. Whilst relatively common in humans, bicuspid aortic valves are rare [...]
Parallel beam forming can be performed in both reception and transmission (Demi et al., 2013). It speeds up the rate of data acquisition (Hoskins et al., 2010), which can be used to increase the frame rate, field of view, more frame averaging to reduce noise, or reduce acquisition time (particularly important for 3D imaging). Parallel [...]
The history of Doppler in the world of medical ultrasound began with spectral Doppler, but its use did not really take off until the introduction of colour Doppler in the early 1980s. Whilst a qualitative modality (arguably semi-quantitative with more recent publications in echocardiography on estimating regurgitant jet size as a percentage of the receiving [...]
Many higher end machines now boast apodization on their list of ultrasound specifications. It sounds like a made-up, gimmicky concept, but it’s actually very important. Here’s why.
SonoScape – one of the world’s leading veterinary ultrasound manufacturers – have recently launched the S9 into the global vet market. And it’s already making waves…
A brief comparison of the leading small animal ultrasound scanners on the market for dog breeders at the moment.
Individuals offering a scanning service to breeders are often put under pressure to give numbers, due dates and – with some animals – even the gender of the foetus or foetuses. Unless you are a qualified veterinarian, it is strongly recommended that you do not do this, as it opens you up to criticism or [...]
A bullet point summary of the cost-saving benefits of ultrasound equipment for breeders and farmers.
