A European myocardial 123I-mIBG cross-calibration phantom study. [PDF]
J Nucl Cardiol, 2018 Planar myocardial 123I-meta-iodobenzylguanidine (123I-mIBG) scintigraphy is a highly reproducible technique. However, differences in collimator use are one of the most important factors that cause variation among institutions and studies in heart-to-mediastinum (H/M) ratio.
