- Dr. Baowei Fei was awarded a five-year NIH R01 grant
January 2, 2017
The project is to translate our positron emission tomography (PET)/transrectal ultrasound (TRUS) fusion guided technology into a commercially supported platform for improving the detection of prostate cancer. It has been reported that the long-term prostate cancer specific survival of patients initially managed with active surveillance (AS) or watchful waiting for low-risk prostate cancer ranges from 97% to 100%. However, among all men with indolent prostate cancer, the rate of aggressive treatment is as high as 64.3%. The costs for the treatment are $12 billion each year in the USA. One reason for aggressive treatment is due to the fact that the current standard diagnosis with transrectal ultrasound-guided biopsy can miss up to 30% of cancers. A major concern for active surveillance is the risk of high-grade cancer that may be missed by the current diagnosis. This research is to develop innovative imaging technology that can improve the detection rate and distinguish aggressive cancer, which requires treatment, from the non-aggressive disease, which can be well-managed with active surveillance. The technology will provide clinicians a new imaging tool to select millions of low-risk prostate cancer patients for active surveillance instead of unnecessary treatment, therefore may help save billions of dollars in treatment costs and improve the care of prostate cancer patients.

- Dr. Baowei Fei served as Chair for NIH Study Section ZRG1 SBIB-F (56)R on Early Phase Clinical Trials in Imaging and Image-guided Interventions
October 21, 2016
This Funding Opportunity Announcement (FOA) is intended to support clinical trials conducting preliminary evaluation of the safety and efficacy of imaging agents, as well as an assessment of imaging systems, image processing, image-guided therapy, contrast kinetic modeling, 3-D reconstruction and other quantitative tools. As many such preliminary evaluations are early in development, this FOA will provide investigators with support for pilot (Phase I and II) cancer imaging clinical trials, including patient monitoring and laboratory studies. This FOA supports novel uses of known/standard clinical imaging agents and methods as well as the evaluation of new agents, systems, or methods. The imaging and image-guided intervention (IGI) investigations, if proven successful in these early clinical trials, can then be validated in larger studies through competitive R01 mechanisms, or through clinical trials in the Specialized Programs of Research Excellence (SPOREs), Cancer Centers and/or the NCI's National Clinical Trials Network.

- Guolan Lu successfully defended her PhD thesis and joined Stanford University
October 14, 2016
As an emerging optical modality, hyperspectral imaging (HSI) holds great promise for early cancer detection and image-guided surgery. The major advantage of HSI is that it is a noninvasive technology that doesn't require any contrast agent, and it combines wide-field imaging and spectroscopy to simultaneously attain both spatial and spectral information from an object in a non-contact way. Light delivered to the tissue surface undergoes multiple elastic scattering and absorption interactions, and part of it returns as diffuse reflectance carrying diagnostic information about the underlying tissue structure and composition. The biochemical and morphological properties of the tissue change during disease progression. Therefore hyperspectral images, which contain high-dimensional spectral information at each image point, can be analyzed for visualization, characterization, and quantification of the disease state in biological tissue.
The overall goal of this dissertation was to investigate the potential of label-free HSI technology combined with machine learning methods as a noninvasive diagnostic tool for quantitative detection and delineation of head and neck cancer. More specifically, this dissertation work has two applications: the early detection of cancer, and surgical guidance. To achieve this, we had four different aims. The first two aims evaluated the diagnostic performance of HSI and machine learning algorithms at differentiating cancer from normal tissue in preclinical animal models, including a subcutaneous cancer model (Aim 1), and a chemically-induced tongue carcinogenesis model (Aim 2). The last two aims investigated the detection and delineation of head and neck cancer in a surgical animal model (Aim 3) and fresh surgical specimens of human patients (Aim 4).
- FDA approves Emory-developed prostate cancer imaging probe (FACBC/Axumin)
June 15, 2016
A cancer imaging agent that was originally developed at Emory University was approved on Friday, May 27 by the U.S. Food and Drug Administration. Axumin, a PET (positron emission tomography) imaging agent, is indicated for diagnosis of recurrent prostate cancer in men who have elevated blood levels of prostate specific antigen (PSA) after previous treatment. Axumin, now being commercialized by UK-based Blue Earth Diagnostics, is also known as 18F-fluciclovine or FACBC (an abbreviation for anti-1-amino-3-[18F]fluorocyclobutane-1- carboxylic acid). Imaging using axumin is expected to help doctors detect and localize recurrent prostate cancer, and could guide biopsy or the planning of additional treatment, says David Schuster, MD, director of the Division of Nuclear Medicine and Molecular Imaging and associate professor of radiology and imaging sciences at Emory University School of Medicine and Winship Cancer Institute. Fluciclovine was originally developed by Mark Goodman, PhD, professor of radiology and imaging sciences at Emory University School of Medicine and Winship Cancer Institute, and Emory Endowed Chair of Imaging Sciences, along with Timothy Shoup, PhD, now at Massachusetts General Hospital. Baowei Fei, PhD, EngD, is researching how to combine fluciclovine with ultrasound to guide prostate biopsy. Fei is associate professor of radiology and imaging sciences, a Georgia Research Alliance Distinguished Cancer Scientist, and part of the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory.

- Dr. Baowei Fei received a five-year NIH R01 grant on molecular image-directed, 3D ultrasound image guided biopsy.
January 15, 2011
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.

October 14, 2010
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.

When Two is Better Than One: Perfecting the Combined MR/PET
- Dr. Baowei Fei received a Coulter Translational Research Award to develop quantification tools for combined MR/PET
July 28, 2010
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.

- Dr. Baowei Fei’s work on photodynamic therapy and nanoparticle-based drug delivery was highlighted by Nature Materials
January 15, 2010
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.
