    Abstract

    Purpose: To report a comparison of SPECT/CT technique with standard blood-based dosimetry methodology in a cohort of non-Hodgkin lymphoma (NHL) patients treated with 131I-rituximab anti-CD20 chimeric monoclonal antibody. Methodology: Red marrow uptake was measured directly using serial quantitative whole-body imaging in conjunction with SPECT/CT in a cohort of 23 patients undergoing routine 131I-rituximab radioimmunotherapy of NHL. Absorbed dose measurements were then compared with radiation doses calculated using standard peripheral blood counting methodology. Results: Activity clearance from whole body of 88.7 hours measured by imaging 131I- rituximab was significantly slower (p
