While digital imaging of all kinds is developing fast, I would hesitate to trust a diagnosis of PD made by a machine! Neuros are only human, and may not get things accurately all the time, but the human eye is infinitely more sensitive to nuance than a computer, and this imaging technology is only as good as the amount of parameters that it measures. Perhaps in several more years, and a lot more research........ the report on MRI, once regarded as practically infallible, recently posted, tells about the true state of technology and medical imaging........ for instance there is no mention of measuring differentials for comparison with other conditions that give gait cues to diagnosis....
