A First Report on [18F]FPRGD2 PET/CT Imaging in Multiple Myeloma. Contrast media & molecular imaging Withofs, N., Cousin, F., De Prijck, B., Bonnet, C., Hustinx, R., Gambhir, S. S., Beguin, Y., Caers, J. 2017; 2017: 6162845

Abstract

An observational study was set up to assess the feasibility of [18F]FPRGD2 PET/CT for imaging patients with multiple myeloma (MM) and to compare its detection rate with low dose CT alone and combined [18F]NaF/[18F]FDG PET/CT images. Four patients (2 newly diagnosed patients and 2 with relapsed MM) were included and underwent whole-body PET/CT after injection of [18F]FPRGD2. The obtained images were compared with results of low dose CT and already available results of a combined [18F]NaF/[18F]FDG PET/CT. In total, 81 focal lesions (FLs) were detected with PET/CT and an underlying bone destruction or fracture was seen in 72 (89%) or 8 (10%) FLs, respectively. Fewer FLs (54%) were detected by [18F]FPRGD2 PET/CT compared to low dose CT (98%) or [18F]NaF/[18F]FDG PET/CT (70%) and all FLs detected with [18F]FPRGD2 PET were associated with an underlying bone lesion. In one newly diagnosed patient, more [18F]FPRGD2 positive lesions were seen than [18F]NaF/[18F]FDG positive lesions. This study suggests that [18F]FPRGD2 PET/CT might be less useful for the detection of myeloma lesions in patients with advanced disease as all FLs with [18F]FPRGD2 uptake were already detected with CT alone.
