Equine Distal Limb CPD questionnaire Question Title * 1. Which of the following is a reason for using a linear probe for ultrasonography of equine flexor tendons? a) The lower frequency associated with linear probes gives better depth of penetration b) The flat face of the transducer means that the ultrasound beam is perpendicular to the parallel fibres of the tendons c) Linear probes are generally cheaper d) None of the above Question Title * 2. Which precautions need to be taken when considering sedating a horse for scanning its legs? Select as many answers as you like. a) Get permission from the owner b) Make sure the sedation will not interfere with potential ‘dope’ testing c) Never sedate horses for scanning their legs – they may fall on you d) None of the above Question Title * 3. Approximately how long after an acute injury should you aim to perform the ultrasound exam, and why? a) 21 days, because before this time ongoing changes due to oedema, haemorrhage, and enzymatic destruction of the tendon fibres can give a false impression of the severity of the injury b) 7 days, because before this time they are likely to be too painful to tolerate being scanned c) 21 days, because before this time they are likely to be too painful to tolerate being scanned d) 7 days, because before this time ongoing changes due to oedema, haemorrhage, and enzymatic destruction of the tendon fibres can give a false impression of the severity of the injury Question Title * 4. In total, how many zones are conventionally used for localising image levels from proximal to distal in the metacarpal region? a) 5 b) 6 c) 7 d) 8 Question Title * 5. What adjustments might you need to make to the ultrasound image once you have placed the probe in contact with the leg but before proceeding with the examination? Select as many answers as you like. a) Gain b) Depth c) Focal position d) All of the above Next
