Buying an ultrasound machine used to be a very different process. A purchase involving hundreds (sometimes thousands) of pounds was one in which people invested months of research, many phone and email conversations, and often met with the ultrasound company face-to-face to try out the equipment, receive training and establish trust. Nowadays, people are becoming increasingly willing to buy straight off the internet, and the personal conversation has been replaced with other methods of building trust – most notably, online reviews. This makes the decision-making process quicker and easier for the buyer......

Scan Pad and wireless probe

Wireless ultrasound probes (or ‘ultrasound wands’) went through a temporary boom in popularity in the UK, before their limitations quickly became obvious. Now, many people who originally invested in wireless scanners are looking to upgrade to higher quality systems. But is there a role for these wireless probes, and if so, what is it? I put a typical wireless ultrasound probe to the test against the VIS Scan Pad to find out the key differences, and examine why not all 128 element transducers are created equal. Bladder scan in a Dogue De......

Ultrasound is not (yet) an exact science. Machine learning is helping to bring us closer to it, but even when this day comes – and it’s currently only in the research stages – it’s unlikely that the human component will ever be completely replaced in our lifetimes. There will always be exceptions to rules, and at the moment, only a human brain is capable of thinking around these instances. Because ultrasound can be so subjective, it’s important that you are part of a supportive community that you can turn to when you......

Thank you to all who attended today’s webinar on how to promote your canine scanning business online. The full recording is embedded here, with the question and answer session in text below.     Questions: Am I right in assuming to be a member of the AUA you have to have completed both Level 1 AND Level 2? You can join as a partial member with only level 1 training, giving you access to your profile which you can then begin building. You can still upload and share your scans here. What......

alpaca face

A normal llama and alpaca pregnancy lasts for an average of 11 and 11.5 months, respectively. Pregnancy is not visually obvious until late pregnancy (if at all) in either species of camelid. The traditional alpaca “spit off” method, where the female treats the male with hostility, actually only confirms ovulation – not a successful pregnancy. It would have to be repeated multiple times several weeks after the last mating to confirm that the female is not pregnant, and even this is not fool-proof, with less experienced female alpacas known to accept the......

When and where should I get my dog scanned for pregnancy? Getting your dog scanned for pregnancy with ultrasound is very reliable and accurate, provided it is performed: At the right time By a trained, experienced professional With the right equipment Each of these points is discussed in turn below.   The right time: When should I get my dog scanned? The earliest you should book an appointment with a mobile pregnancy scanner is when your dog would be at 30 days gestation. If you have been performing progesterone testing, you may......

Tissue Harmonic Imaging is a relatively recent discovery that greatly improves image quality, primarily due to a great reduction in the amount of ultrasound artifacts (see Chapter 14 of Ultrasound for Canine Pregnancy Scanning). Put simply, it involves sending out ultrasound at one frequency, but only using higher returning frequencies (that we didn’t used to know were even generated!) to generate the image. These higher frequencies are created as the ultrasound waves pass through tissue, so are particularly helpful when scanning larger animals – less helpful when scanning shallow structures that are......

Dogs and cats with significant mitral regurgitation (MR) may show pulmonary venous flow reversal. Flow reversal is a supporting measure only, and not specific enough to be used as a standalone method of grading MR severity.   Normal pulmonary vein flow pattern The normal flow pattern of the pulmonary veins shows two forward-flowing waves – systolic (S) and diastolic (D). The S wave should be of equal or greater velocity than the D wave. There is also a small reversal wave (Ar) that occurs at the time of atrial contraction. This is present even......

An increasing number of AUA members are turning to scanners with Doppler capability as their next ultrasound machine. Primarily, this is due to the higher resolution images they tend to produce (colour Doppler systems use higher spec graphics cards and other components, so even if you never use your colour, you still benefit from improvements in performance), but there are ways you can put your Colour Doppler to good use.     Remember that Doppler imparts higher levels of ultrasonic energy, and should be used sparingly over the foetus itself. Obstetric sonographer......
