About the project
Neuroimaging plays an essential role in human clinical neuroscience. As imaging technology advances, the large-scale high-quality data could provide important insights of the pathology of neurological disorders, such as Alzheimer's disease. In this project, I aim to analyze the neuroimaging data and integrate the findings into computer aided diagnosis pipelines for Alzheimer's disease and mild cognitive impairment (MCI). The main objective of this project is to identify the early signs of cognitive impairment, thus keep contributing to the long-term objective, which is to deliver integrated and patient-centered healthcare to individuals with Alzheimer's disease or MCI.
The overarching goal of Mr Liu's research is to establish standardized methods for early diagnosis of Alzheimer’s disease with the neuroimaging-based biomarkers. He has made the concrete progress towards achieving my research aims. Firstly, he designed a new framework for multi-stage diagnosis of Alzheimer’s disease (AD). It is well known that mild cognitive impairment (MCI) patients have high risks to develop AD than the normal aging people. Therefore, it is very important to identify the MCI patients among normal aging people, so that we could provide them early medical interventions. This new framework is capable of accurate diagnosis of multi-stage AD, including normal aging, MCI and AD.
Secondly, he investigated the imaging data from multiple sources/modalities simultaneously. Research has indicated that multi-modal data could provide complementary information to each other, thus enable him to achieve more accurate diagnosis of AD. Currently, the positron emission tomography (PET) and magnetic resonance imaging (MRI) data were used in his project, but other modalities can also be seamlessly integrated. Thirdly, he designed several intelligent algorithms to detect the disease-specific biomarkers and discover their semantic association to the diseases. In particular, he developed a high-level neural network to mimic the human brain, which could learn the brain atrophy and hypo-metabolism patterns of AD and MCI patients automatically.
