    Feasibility of Dedicated Breast Positron Emission Tomography Image Denoising Using a Residual Neural Network by Koji Itagaki, Kanae Miyake, Minori Tanoue, Tae Oishi, Masako Kataoka, Masahiro Kawashima, Masakazu Toi, Yuji Nakamoto

    Published 2023-06-01
    “…Objective(s): This study aimed to create a deep learning (DL)-based denoising model using a residual neural network (Res-Net) trained to reduce noise in ring-type dedicated breast positron emission tomography (dbPET) images acquired in about half the emission time, and to evaluate the feasibility and the effectiveness of the model in terms of its noise reduction performance and preservation of quantitative values compared to conventional post-image filtering techniques.Methods: Low-count (LC) and full-count (FC) PET images with acquisition durations of 3 and 7 minutes, respectively, were reconstructed. …”

    Published 2011-11-01
    “…In patients with World Health Organization (WHO) grade III glioma with a lack of or minimal (< 1 cm 3 ) magnetic resonance imaging (MRI) contrast enhancement, the volume of the metabolically active part of the tumor was assessed by [ 11 C]-methionine positron emission tomography (MET-PET). Eleven patients with WHO grade III gliomas underwent MET-PET and MRI (contrast-enhanced T 1 -and T 2 -weighted images). …”
