The top row is from a patient with (A) normal baseline FP-CIT and (B) abnormal cardiac MIBG with no visible uptake in the myocardium and heart-to-mediastinum count ratio (HMR) of 1.44. The bottom row is a patient with (C) baseline FP-CIT rated as abnormal and (C) normal cardiac MIBG with HMR of 2.23.
