Can I scan pregnant women?

As tempting as it may be to turn your training and ultrasound machine to use on pregnant humans, unless you have registered as a provider with the Care Quality Commission (CQC), offering this as a service is illegal in the United Kingdom. The CQC specifically lists ultrasound scanning as a regulated activity: “All diagnostic procedures involving the use of any form of radiation (including x-ray), ultrasound or magnetic resonance imaging to examine the body are included.” This applies to “all organisations” including people “offering care in your home.” There is no grey area......

Canine Pulmonary Stenosis

A puppy was referred for echocardiography for suspicion of a PDA, due to a grade six heart murmur. We actually found severe pulmonary stenosis, and you can follow the story of this case in this video: This case was referred for balloon valvuloplasty, and I was introduced to a term I hadn’t heard before: suicide right ventricle. The referral centre stated that because of the right ventricular hypertrophy – in particular in the infundibular region – there was a significant risk of dynamic obstruction occurring with the sudden drop in valve pressure......

Ultrasound Qualification

It is important to realise that there is no official qualification available to lay scanners in animal pregnancy scanning. This did not used to be a huge problem, but in a post-Trump world where qualifications count for nothing (and savvy marketing for everything), there are now a lot of choices out there for training in animal pregnancy scanning. How do you know which course to pick? You could do one of two things: Ask “is this person/company qualified to teach me?” Will attending a course with them mean anything and teach me anything?......

It’s no secret that the animal scanning industry has been infiltrated by rogue elements over the last few years. The Animal Ultrasound Association has led the fight against unethical, poor quality ultrasound training practices since 2016, but for every person that we educate, there’s someone new to the industry just starting out and being drawn in by false promises and flashy marketing on the internet. Many of these people will be left feeling dissatisfied, and come to us for advice on where to get retrained. But equally, there are many others who......

CPD accreditation

Continued Professional Development – CPD – has two main purposes. (1) It demonstrates that the course you are attending has been properly structured. (2) It awards you CPD points. The first point is important, but note it only assures you of the overall structure of the course and compliance with certain standards, such as anti-discrimination and inclusivity policies. It does not mean that the content of the course has been checked by anyone qualified to do so. The second is a moot point. Breeders do not collect CPD points and submit them......

The fundamental difference between veterinarians and ultrasound technicians

I’ve seen quite a few cases recently where very competent scanning professionals within our community have found something that doesn’t look right, referred it to the vet as they should, only for the vet to give the animal the all clear and send her straight home. No feedback is given either by the vet or the owner to the person who made the referral, and this can be very disconcerting. You might feel any or all of the below: Guilty for “wasting” the owner’s time and causing unnecessary stress. Filled with self-doubt:......

biparietal diameter

Most veterinary ultrasound machines come with gestational age calculation packages inbuilt. Within any one species, however, results are not universally accurate across all breeds. There can be huge breed variation, with some species (e.g. goats) and some breeds (e.g. chihuahuas) suffering more than others. Vieira et al.’s 2020 study sought to improve the accuracy of gestational age calculations in chihuahuas – a small dog which, nevertheless, has a large head in comparison to its body size. As chihuahuas are at increased risk of complications during delivery, it is important to be able......

Umbilical artery Doppler

Summary The resistance index is quick and easy to calculate on ultrasound machines with PW Doppler capability. Obtaining useful readings from the umbilical artery in dogs takes a lot of practice, and should be obtained from the mid-cord to ensure reproducibility. The resistance index will fall 12 hours prior to delivery, falling further 1-6 hours before, so can be used to predict when labour should begin. If the resistance index falls but labour does not follow, this can alert the breeder or vet to the possible need for veterinary intervention. M-mode can......

rabbit ultrasound scan

How early can I scan a rabbit? Positive confirmation of pregnancy has been documented as early as 7 days in rabbits, but only by the presence of fluid inside the uterus, which is a sensitive but not specific sign of pregnancy: in other words, you’ll always see it in a pregnant rabbit, but you could also see it in a rabbit coming in or out of season, or when something is wrong. It is also worth noting that in such studies, rabbits were completely shaved and mechanically restrained on their backs. While......
