She became the Vice-Chair in 2008 Chair in 2016 of the Department of Radiology of Henan Provincial People’s Hospital in China.
Below is a summary of her presentation.

In this talk, the applications of three non-contrast enhanced advanced MR techniques, including Diffusion Kurtosis Imaging (DKI), Strategically Acquired Gradient Echo (STAGE) and a Length and Offset Varied Saturation (LOVARS) in central nervous system (CNS) were summarized.

DKI has been used to measure non-Gaussian diffusion, which has the potential to characterize both normal and pathologic tissue better than diffusion-tensor imaging. Some previous researchers have suggested that DKI might provide more accurate information about water diffusion. Dr. Wang's study showed that mean kurtosis values may provide additional information and improve the grading of gliomas compared with conventional diffusion parameters.

STAGE is an advanced Susceptibility weighted imaging (SWI) which can provide multi-contrast images in one scan, such as T1W, PDW, T1 MAP, PD MAP, R2* MAP, SWI, and even MRA images in 5 minutes. It is very helpful in early detecting and evaluating ischemia, brain trauma and some other CNS diseases.

Below is a summary of her presentation

Inverse problems are ubiquitous in the field of medical imaging and image processing. Prominent examples include fast MR imaging and image denoising. The goal of these problems is to reconstruct or restore an unknown image from a set of direct/indirect measurements. However, due to the limitation of the acquisition time or the existence of noise, the obtained measurements are often corrupted or incomplete, which introduces big challenges for the reconstruction process and the following clinical diagnosis. In order to remove the noise or overcome the ill-posed nature caused by the insufficient measurements, it is necessary to explore the prior knowledge and utilize them to form constraints in the reconstruction process so as to make up for the missing or corrupted information.

Dr. Kwon

For decades, molecular imaging which can monitor inter-/intracellular functions or molecular processes in an organism has provided valuable information for various research fields. Biomarkers such as enzymes, receptors and proteins can be utilized as a target of molecular imaging since they can provide information for early diagnosis and monitoring therapeutic effect of diseases. Among them, receptor-ligand interaction based molecular imaging technique has been emerging promising strategy in theragnosis of intractable diseases such as cancer.
In this talk, Dr. Kwon introduced epidermal growth factor receptor (EGFR) and CD 47 receptor-specific self-quenched imaging probes, which can emit fluorescence (activate) via de-quenching reaction in lysosome. His talk also included a simple noninvasive labeling and tracking technique for cell therapeutics via combination of metabolic glycoengineering and biootherogonal copper-free click chemistry, resulting in the cells being tracked via near-infrared fluorescence (NIRF), magnetic resonance (MR) and computed tomography (CT) imaging without cytotoxicity and functional interference.

Dr. Gomez delivering his lecture

The use of chemogenetic technologies has produced minimally invasive techniques to modulate specific brain structures and/or neural networks in research animals and potentially in humans. Utilizing these methods has provided a boon in behavioral testing that does not involve the hindrance of movement restricting devices. Assisted by PET, Dr. Gomez's lab has characterized the mechanism of action of existing chemogenetic ligands used for activating virally implanted “designer” receptors. Data gathered from these experiments has led to novel revelations about the mechanism of action of popular chemogenetic technologies and more recently to synthesis of novel chemogenetic actuators and PET ligands with high affinity and efficacy for established chemogenetic receptors. Their goal is to leverage the availability of such minimally-invasive neuromodulation technologies with biobehavioral PET imaging methods to study pertinent behavioral neuroscience questions.
