Cardiac PET/MR Imaging in Small Rodents

December 14, 2021 | 9:00 AM Eastern Standard Time | 3:00 PM Central European Time

Webinar Overview

We are pleased to welcome you to this webinar, which focuses on preclinical cardiac PET/MRI, cardiac and respiratory gating and streamlined PET and MRI analysis.

After briefly motivating cardiac and respiratory gating in cardiac imaging, various implementations developed to address cardiac and respiratory gating in MRI and PET will be discussed. Prospective and retrospective gating methods are explained. The self-gated approach, IntraGATE, is introduced, pointing out the principle of operation and main advantages gained using this technique. Building on the principle of exploiting the MR navigator signal to derive details on the cardiac and respiratory motions, the concept of spatially resolved navigators, using PolyGATE, is presented for imaging multiple animals simultaneously.

The Cardiac PET tool from PMOD brings a streamlined workflow to quantitative PET analysis for dynamic PET, or function analysis for gated PET. Similarly, the Cardiac MR tool facilitates function analysis of cardiac cine series such as Bruker’s IntraGATE, and can leverage PMOD’s Artificial Intelligence framework, PAI. PAI is a flexible framework that makes user-defined AI-based segmentation and classification accessible without requiring programming experience.

Biomedical Engineer, Biomedical MRI group/ MoSAIC
Katholieke Universiteit (KU) Leuven

Matic Pusovnik is a biomedical engineer, currently doing a PhD project at the Biomedical MRI group/ MoSAIC, Department of Imaging and Pathology, Katholieke Universiteit (KU) Leuven, Belgium. Matic studied at the University of Ljubljana and KU Leuven. He first joined the group as a thesis student working on image processing/ quantification, but now continues to fuel his passion for MRI in his PhD project. In his research, he mostly focuses on developing new image acquisition and processing tools for cardiac imaging/ MR fingerprinting in rodents. He is supervised by Dr. Willy Gsell and Prof. Uwe Himmelreich who have recently focused on cardiac MRI and in particular on simultaneously acquired PET/MR imaging in rodents.
