This exhibit will review key information related to the imaging of pediatric neuroblastoma with I-123 MIBG and the treatment of stage IV neuroblastoma with I-131 MIBG. Key teaching points will include:
Proper scan preparation and technique are critical for obtaining high quality MIBG images
Knowledge of the normal biodistribution of MIBG is essential for accurate scan interpretation
SPECT/CT imaging helps identify disease sites and aids in differentiating sites of physiologic uptake
Curie scoring can be used to quantitate disease extent and response
I-131 MIBG therapy requires meticulous technique and specific imaging/follow-up protocols
