“Though the reported correlations between CT‐P and SPECT‐P are promising, more research is required to determine the CT acquisition protocol and numerical method implementation that yield the highest physiological fidelity.”
Interesting the more I look at the technology.
Seems as though 4DX isn’t the only group doing CTVQ.
4DX say they have the data but none of it is published, so it’s only company data. They have a study going with Mac Uni, which is due to to complete in 2027 I think.
Also, it’s not correct to say there is no radiation, because there is a ct scan. Nuclear VQ SPECT is lower dose than non contrast CT.
