Resolution Recovery

The audit of use of resolution recovery software to enable reduced count acquisition of myocardial perfusion SPECT is now completed. We were very pleased with the response from nuclear medicine departments in the UK. Twenty-four centres were each able to send us 50 anonymised patient studies, from which the NMSQG generated simulated half-count data. Each centre then reconstructed their own half-count data using their locally installed resolution recovery software and reported the result whilst blinded to the original report. The reports of the half-count data reconstructed with resolution recovery were then compared with the original report from the full count data using the departments standard method. By the end of December 2012, sixteen centres had managed to complete the audit and we are very grateful to all the staff in these centres who put in so much time to carry out this study.

We submitted a report of the results to the Department of Health and to ARSAC who initiated this study in January 2013. We have given feedback to all participating centres about how their results compared with other centres. The results have been presented orally at the BNCS meeting in December 2013 and the BNMS meeting in May 2014.
A full paper was published in Nuclear Medicine Communications in May 2014.

    We have a trial of UltraSPECT Resolution Recovery. Our centre doesn’t scan enough patients to be considered in the national audit. I would like to test the software locally using half count data but our cameras do not allow serial acquisitions. I’m interested to know how your software for generating half count data works – is it freely available?

    The software is not fully validated and so is not available for general use but we may be able to some assistance (we will contact you privately to discuss this).

    I know we wouldnt be able to participate in the UK audit but I am very interested in conducting this audit of our centre in Manitoba – we have six NM departments that carry out myocardial perfusion studies (high volumes in at least 2/3 centres and most if not all of them have or will soon get some form of myocaridal specific resolution recovery software, all from 2 well known vendors. I would be more than willing to help with the UK audit if it could also help me do the same here in Manitoba, Canada.
    Many Thanks
