Purpose: Quantitative 18F-fluorodeoxyglucose positron emission tomography is limited by the uncertainty in lesion delineation due to poor SNR, low resolution, and partial volume effects, subsequently impacting oncological assessment, treatment planni

PURPOSE Design, realization, scan, and characterization of a phantom for PET Automatic Segmentation (PET-AS) assessment are presented. Radioactive zeolites immersed in a radioactive heterogeneous background simulate realistic wall-less lesions with k

Purpose To optimize signal-to-noise ratio (SNR) in fast spin echo (rapid acquisition with relaxation enhancement [RARE]) sequences and to improve sensitivity in 19F magnetic resonance imaging (MRI) on a 7T preclinical MRI system, based on a previous

A review of recent works by our group in the segmentation and quantification of oncological lesions in 18-fluoro-deoxy-glucose (FDG) positron emission tomography (PET) images is given, stressing the underlying model assumption. In a first approach, a

Purpose: In recent years, segmentation algorithms and activity quantification methods have been proposed for oncological 18F- fluorodeoxyglucose (FDG) PET. A full assessment of these algorithms, necessary for a clinical transfer, requires a validatio

In 19 F-MRI studies limiting factors are the presence of a low signal due to the low concentration of 19 F-nuclei, necessary for biological applications, and the inherent low sensitivity of MRI. Hence, acquiring images using the pulse sequence with t

In this work we propose a strategy to jointly estimate activity and borders of oncological lesions in PET/CT. The starting step is constituted by a lesion contouring on PET image volume and by a Gaussian Mixture Model (GMM) clustering which individua
