MRI-Driven Diffusion Model of 18F-FP-CIT PET Image Synthesis for Parkinson's Disease

Key Points

The model improves diagnostic accuracy for Parkinson's disease using MRI-derived PET images, and has shown robust performance in tests.
High accuracy of the MRI to PET conversion was achieved, showing significant promise over traditional image synthesis methods.
Developed a conditional diffusion approach, leveraging MRI data and patient information to successfully generate PET images.
This technique could significantly aid in the functional assessment of Parkinson's disease, addressing gaps in current diagnostic practices.

Abstract

Motivation: In diagnosing Parkinson's disease (PD), MRI provides clear structural information and is radiation-free, but not capture functional data like PET. Goal(s): Develop a method to convert MRI images to PET using a conditional diffusion model, aiming to improve PD diagnosis. Approach: We developed a conditional diffusion-based method that uses MRI images and basic patient information as inputs to generate corresponding PET images. Results: Our model demonstrated high accuracy and robustness compared to conventional synthetic image methods. Impact: This development is valuable for the diagnosis of PD in patients, offering a potential tool to enhance diagnostic capabilities.
