From: Analysis of quantitative [I-123] mIBG SPECT/CT in a phantom and in patients with neuroblastoma
Example of quantitative SPECT analysis of a patient undergoing treatment for 1 year and 4 months. a The primary paraspinal thoracic tumor was quantified by determining maximum SUV value and compared with long-axis length measurements of the larger presentation of the multifocal tumor. An SUV measurement was performed in the liver to provide a baseline SUV value for normal background uptake. b Transaxial reconstructed images were captured at 10 time points, with c selected coronal reformats shown to provide general context of the tumor size, avidity, and response to therapy compared to whole-body uptake
