This study focused on the accuracy of standardized uptake value (SUV) reconstructed using the corrected MR attenuation correction (MRAC) images with time-of-flight (TOF) information by PET in patients with metallic implants. We compared the SUV of both paraspinal and psoas muscles in patients with and without implant for TOF reconstructed PET images. In the result, there was no significance in the SUV measurements obtained from MRAC between no-implant and with-implant patients. And therefore, our study demonstrated that SUVs measured from TOF PET/MR of lumbar implant indicated good reliability and robust of MRAC.
