MOLECULAR IMAGING GROUP

Introduction

Biomedical molecular imaging is the technology that successfully combined molecular biology and clinical medicine, and it will be one of potential fields of medicine in the future. Generally, there are three advantages on molecular imaging research: First, it can transform complicated processes of gene expression and signal transduction into image visually, and that one can realize the possible disease mechanism and features; Second, it’s able to find early on molecular variations of disease and the process of pathology; Last, it can in vivo observe continuously the mechanism and effect on drug or gene therapy. Biomedical molecular imaging integrated molecular biochemistry, data processing, nanotechnology and imaging processing, and then it possesses the properties of high specificity, high sensitivity and ultra-high spatial resolution. Therefore, if it used in clinical application then could really provide the data about quality, location and quantification for clinical diagnosis.

Our research

A main challenge in molecular imaging is low signal source. To acquire better MR molecular images, two major methods in our lab were utilized to enhance the sensitivity: 1. to enhance the sensitivity by MR techniques (e.g. Quantitative susceptibility mapping, home-made coil, SQUID and wideband technique); 2. to reduce the false positive rate by delievering contrast agent like Mn2+ and Fe3O4.

Quantitative susceptibility mapping (QSM)





Functional QSM in rodent




Home-made coil




Nano particle with SQUID detection




Wideband Technique




Nano particle synthesis and animal application





Integration to Pathology

Once the technical part for molecular imaging is established, we would then optimized preclinical machine parameters and apply to animal pathology model. Studies like measuring dynamic microcirculation of multiple lesion sites (WB-DCE), ADC map to evaluate chemotherapy effects of lung carcinoma; perfusion changes in Alzheimer's Disease animal are all manifest understanding toward diseases with the aid of modern molecular imaging.


Simultaneously Quantify Ktrans toward multiple lesion sites using Wideband technique




ADC map to evaluate chemotharapy in lung cancer rats




Brain activity evaluation of Alzheimer's Disease rats
