Dopamine Cell Implantation in Parkinson's Disease: Long-Term Clinical and ¹⁸F-FDOPA PET Outcomes

Abstract

These results suggest that clinical benefit and graft viability are sustained up to 4 y after transplantation. Moreover, the dependence of clinical (but not imaging) outcomes on subject age and sex at 1 y may not persist over the long term. Last, the imaging changes reliably correlate with clinical outcome over the entire posttransplantation time course.
