Local detection of prostate cancer by positron emission tomography with 2-fluorodeoxyglucose: comparison of filtered back projection and iterative reconstruction with segmented attenuation correction

摘要

Conclusion. In selected patients, cancer can be imaged within the prostate using FDG-PET, and IRSAC is superior to FBP in image reconstruction for local tumore visual- ization. Background. To compare filtered back projection(FBP) And iterative reconstruction with segmented attenua- Tion correction(IRSAC)in the local imaging of prostate Cancer by positron emission tomography with 2-fluo- Rodeoxyglucose(FDG-PET(. Methods. We retrospectively identified 13 patients with Primary(n = 7)or recurrent(n = 6)prostate cancer who Had increased uptake in the prostate on FDG-PET per- Formed without urinary catheterization, contempora- Neous biopsy confirming the presence of active tumor in The prostate, and correlative cross-sectional imaging by MRI(n = 8)or CT(n = 5).
