Radioactive iodine labelled MIBG cardiac sympathetic imaging is less promising in differentiating PD from other parkinsonism for early onset patients

Conclusions: There is an interaction between age at onset and disease group for H/M ratios. 131I-MIBG cardiac sympathetic imaging is less promising in differentiating PD from other parkinsonism for early-onset patients.
