Dr. Baowei Fei received a five-year NIH R01 grant on molecular image-directed, 3D ultrasound image guided biopsy.
Prostate cancer affects 1 in 6 men in the USA. Every man over the age of 45 is at risk for prostate cancer. Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. More than 1.2 million prostate biopsies are performed annually and the medical cost is more than two billion dollars each year. However, this technique has a significant sampling error and is characterized by low sensitivity (39-52%). The current biopsy approach can miss up to 30% of prostate cancers. As a negative biopsy does not preclude the possibility of a missed cancer, both the physicians and patients face challenges in making treatment decisions. Due to the increasing number of younger men with potentially early and curable prostate cancer, this problem must be addressed in order to improve cancer detection rate. This project is to develop a molecular image-directed, 3D ultrasound-guided system for targeted biopsy of the prostate. If completely developed, the multimodality molecular image-guided system will be able to be used not only for biopsy but also for brachytherapy, radiofrequency thermal ablation, cryotherapy, and photodynamic therapy. The research could improve prostate cancer detection by using novel molecular imaging technology and by using a new three-dimensional image-guided biopsy device. The molecular image-guided system can be used not only for improved biopsy of diseases but also for minimally invasive therapy of cancers.

Dr. Baowei Fei's research is highlighted by Emory Magazine
Double Vision - By Mary J. Loftus
"The combined system can provide opportunities for basic research and can open a new window to studying diseases such as Alzheimer's, Parkinson's, drug addiction, cancer, and cardiovascular disease," says Assistant Professor of Radiology Baowei Fei, a Georgia Cancer Coalition Distinguished Scholar. Dr. Fei's team is working to develop and improve imaging software for the hybrid system. - Autumn 2010

Dr. Baowei Fei's work on MR/PET is highlighted as a featured innovation at the Office of Technology Transfer (OTT) at
Magnetic resonance imaging (MR) shows details about the soft tissues of the body, such as every curve and indentation in the brain, while positron emission tomography (PET) records processes, such as how much energy is being used or how much blood is flowing into a region. When these imaging techniques were combined in the same scanner a few years ago, a real challenge since the MRI's strong magnetic field and the PET's detector and electronics tend to interfere with each other scientists started thinking about the potential wealth of information that could be provided.

Dr. Baowei Fei's work on photodynamic therapy and nanoparticle-based drug delivery was highlighted by Nature Materials
Photodynamic therapy (PDT) is a promising method for treating several cancers that uses photosensitizers. The photosensitizer accumulates in target tissue and is excited using light, generating reactive oxygen species that induce cell death. To enter the target area PDT drugs need to be lipophilic, however this presents problems: lack of solubility in the physiological conditions experienced en route to the target means that they usually take at least 24 hours to get to the tumour. Baowei Fei, Clemens Burda and co-workers have synthesized a PDT drug complex that significantly decreases the delivery time and enables quantitative monitoring of the process. Polyethylene glycol (PEG; a compound approved for human intravenous applications) is attached to gold nanoparticles functionalized with the PDT drug, silicon phthalocyanine-4. Chains of PEG wrap around the drug allowing the system to disperse in aqueous conditions. Free silicon phthalocyanine-4 takes 1-2 days to accumulate in a tumour site; using the new complex this is reduced to less than two hours in vivo in cancer-bearing mice with the tumour reducing in size within one week of treatment.

Dr. Baowei Fei received a Coulter Translational Research Award to develop quantification tools for combined MR/PET
PET (Positron Emission Tomography) provides insight into the metabolic and functional alterations related to pathologic process, and CT (Computed X-Ray Tomography) and MRI (Magnetic Resonance Imaging) reveal anatomical changes due to diseases. The combination of two imaging modalities significantly expands their utility, improving sensitivity and specificity for disease detection and diagnosis. With this grant from the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University Dr. Fei and his team will develop image quantification tools that include image registration, classification, segmentation, and attenuation correction for potential use in combined MR/PET. - July 2010

Dr. Baowei Fei received a Pilot grant from the NIH-funded Emory Molecular and Translational Imaging Center
We envision that molecular imaging can detect cancer at the cellular level, can monitor drug distribution in vivo, can guide therapy to the target, and can evaluate efficacy immediately after therapy. Dr. Fei and his team will develop and evaluate multimodality imaging methods (fluorescence imaging, PET and MR imaging) for early detection of therapeutic response in pre-clinical cancer models. - September 2009.
Dr. Baowei Fei was selected as a Georgia Cancer Coalition Distinguished Cancer Scholar
The Georgia Cancer Coalition established the Distinguished Cancer Clinicians and Scientists program as the cornerstone of its research agenda. The goal of the program is to recruit to Georgia leading and nationally renowned cancer clinicians and scientists who are engaged in the most promising areas of cancer research. The selection of the scholars is closely aligned with the National Cancer Institute's "Extraordinary Opportunities in Cancer Research," which has identified areas of discovery that hold promise for making significant progress against all cancers. This competitive and prestigious award carries with it a five-year grant payable to Emory University to support Dr. Fei's research on cancer imaging. - June 15, 2009
