However, there are few studies which show any benefit from the use of diagnostic ultrasound as a screening tool in the general adult population. The Department of Health has recognized that screening for abdominal aortic aneurysm (AAA) is effective in men over 65 and has started a programme to implement this: please click here to visit this NHS site. 

The benefits of diagnostic ultrasound in symptomatic patients are only achieved by those who have undergone extensive training in the correct operation of the equipment and relevant diagnostic procedures and in the interpretation of ultrasound images.  For assessment of the vascular system, e.g. the carotid arteries, it is important that investigations are carried out and interpreted in accordance with nationally agreed protocols.

All diagnostic ultrasound investigations should be carried out only by those who are suitably trained and appropriately qualified and registered as such with a recognized suitable regulatory body who will ensure fitness to practice.  All ultrasound equipment and services should be subject to regular quality assurance assessments and audit to ensure compliance with nationally recognized standards of practice. All examinations should be properly reported and there must be a method in place for appropriate dissemination of results and for ensuring that prompt action is taken on the rare occasion where a serious condition maybe detected.

As there is no perceived clinical benefit from non-diagnostic scanning applications, the equipment should be operated at a reduced output level as specified in the BMUS safety guidelines (please click here to view these).  The discovery of non symptomatic vascular disease may lead to unnecessary anxiety in some individuals, where the real risks to their health from such disease are small.

Anyone who wishes to have an ultrasound screening scan carried out at a private clinic should ensure that the above recommendations are met.  Clients should ensure that the clinic has procedures in place to deal with any findings in a sensitive and professional manner.
