There was, however, large inter-departmental variability.
In general, the intra-departmental variability for EDV, ESV, and EF was small, whereas inter-departmental variability was larger.
In general, the intra-departmental variability for EDV, ESV, and EF was small, whereas inter-departmental variability was larger (Figure 1).
There was, however, large inter-departmental variability, which needs to be further addressed.
The large inter-departmental variability is however of concern, both for cardiac volumes and for EF.
Our study shows that there is a large inter-departmental variability of EF, EDV, and ESV estimations in nuclear medicine departments in Sweden, but the intra-departmental variability was found to be small.
Evaluation of inter-departmental variability of EF, ESV, and EDV has been performed by Verberne et al. [7].
The aim of this study was to evaluate the inter-departmental variability of EF, ESV, and EDV obtained from gated MPS in Sweden.
The aim of this study was to evaluate the inter-departmental variability of EF, ESV, and EDV during gated MPS in Sweden.
Since the evaluation of EF to a large extent is automated, there should be a small intra-departmental variability and we are recommending that departments that have a larger intra-departmental variability should perform an internal quality control of their method.
Over the 13-year period spanned by the study, there was some variability in the standard departmental treatment protocols.
