Conclusion
The purpose of our study was to investigate the ability of SDCT to differentiate intra-cranial haemorrhage from iodinated contrast in a phantom model.
Measuring the retention of attenuation in a ROI,
by comparing attenuation on VNC to conventional images,
showed excellent accuracy for detecting haemorrhage.
Additionally,
we propose a method of classification,
allowing accurate estimation of the haemorrhagic component size.
A >20% cut-off value for VNC attenuation retention,
detected the presence of all haemorrhagic components.
In conclusion,
our results show SDCT has high accuracy for differentiating intra-cranial haemorrhage from iodinated contrast.
Additionally,
size estimation of the haemorrhagic component can be accurately performed when faced with a mixture of iodine and haemorrhage.
Therefore,
we conclude SDCT can be of added value compared to conventional CT in stroke patients who have undergone therapy,
without hindering standard,
established clinical flow.
