Relationship of H/M ratios obtained on LFOV and SFOV-HE systems
H/M ratios as described will be calculated for the LFOV, and SFOV-HE data sets to determine the correlation between the two measurements. The r value, slope and intercept of this correlation will constitute the primary endpoint of this study. Specifically, we will establish the r value, slope and intercept for: LFOV-Planar vs LFOV-TOMO, LFOV-Planar vs SFOV-HE-TOMO, LFOV-TOMO vs SFOV-HE-TOMO.
Time frame: 3 months post-enrollment close
Image Quality
We will investigate differences between the measurements in the SFOV-HE using the forward projections of the tomographic data and tomographic measurements of the H/M as other methods of establishing the correlation between tomographic and planar measurement of mIBG uptake.
Time frame: 3 month post-enrollment close
