Statement of Need
The evaluation of the functional status of cardiac sympathetic innervation on 123I-MIBG imaging has never gained wide clinical application.
SPECT 123I-MIBG imaging allows the assessment of cardiac regional sympathetic heterogeneity, a parameter of possible clinical impact in different pathological conditions.
While relevant alterations of cardiac sympathetic tone associate with left ventricular hypertrophy, the causal interaction between these two entities has still to be defined.
Combined cardiac perfusion and innervation imaging has been suggested for the assessment of novel functional parameters (i.e., burden...
