[Correlation between Evaluation Methods of Short-time Neuromelanin MRI and SBR by Dopamine Transporter Scintigraphy].

Purpose: To verify the usefulness of three evaluation methods of short-time neuromelanin MRI, correlations between each method and the specific binding ratio (SBR) of dopamine transporter scintigraphy were investigated.

Methods: Short-time neuromelanin MRI was used to measure the contents of melanin-containing cells in the midbrain substantia nigra based on the following methods. Method 1 evaluates the volume of the high-signal area of the midbrain substantia nigra.
