Decoding the Heterogeneity of Malignant Gliomas by PET and MRI for Spatial Habitat Analysis of Hypoxia, Perfusion, and Diffusion Imaging: A Preliminary Study

Autor: Michele Bailo, Nicolò Pecco, Marcella Callea, Paola Scifo, Filippo Gagliardi, Luca Presotto, Valentino Bettinardi, Federico Fallanca, Paola Mapelli, Luigi Gianolli, Claudio Doglioni, Nicoletta Anzalone, Maria Picchio, Pietro Mortini, Andrea Falini, Antonella Castellano

Publikováno v: Frontiers in Neuroscience, Vol 16 (2022)

BackgroundTumor heterogeneity poses major clinical challenges in high-grade gliomas (HGGs). Quantitative radiomic analysis with spatial tumor habitat clustering represents an innovative, non-invasive approach to represent and quantify tumor microenvi

Preliminary Results of an Ongoing Prospective Clinical Trial on the Use of 68Ga-PSMA and 68Ga-DOTA-RM2 PET/MRI in Staging of High-Risk Prostate Cancer Patients

Publikováno v: Diagnostics, Vol 11, Iss 11, p 2068 (2021)

The aim of the present study is to investigate the synergic role of 68Ga-PSMA PET/MRI and 68Ga-DOTA-RM2 PET/MRI in prostate cancer (PCa) staging. We present pilot data on twenty-two patients with biopsy-proven PCa that underwent 68Ga-PSMA PET/MRI for

Low-dose CT for the spatial normalization of PET images: A validation procedure for amyloid-PET semi-quantification

Autor: Luca Presotto, Leonardo Iaccarino, Arianna Sala, Emilia G. Vanoli, Cristina Muscio, Anna Nigri, Maria Grazia Bruzzone, Fabrizio Tagliavini, Luigi Gianolli, Daniela Perani, Valentino Bettinardi

Publikováno v: NeuroImage: Clinical, Vol 20, Iss , Pp 153-160 (2018)

The reference standard for spatial normalization of brain positron emission tomography (PET) images involves structural Magnetic Resonance Imaging (MRI) data. However, the lack of such structural information is fairly common in clinical settings. Thi

A Simple Contrast Matching Rule for OSEM Reconstructed PET Images with Different Time of Flight Resolution

Autor: Luca Presotto, Valentino Bettinardi, Elisabetta De Bernardi

Publikováno v: Applied Sciences, Vol 11, Iss 16, p 7548 (2021)

Background: Time-of-Flight (TOF) is a leading technological development of Positron Emission Tomography (PET) scanners. It reduces noise at the Maximum-Likelihood solution, depending on the coincidence–timing–resolution (CTR). However, in clinica

Optimizing the frame duration for data‐driven rigid motion estimation in brain PET imaging

Autor: Michael Zeineh, Timothy Deller, Samuel A. Hurley, Alan B. McMillan, Valentino Bettinardi, Mackenzie L. Carlson, Floris Jansen, Matthew G. Spangler-Bickell, Greg Zaharchuk

Publikováno v: Med Phys

PURPOSE: Data-driven rigid motion estimation for PET brain imaging is usually performed using data frames sampled at low temporal resolution to reduce the overall computation time and to provide adequate signal-to-noise ratio in the frames. In recent
