Research Title: Measurement of MR brain connectomics in glioma patients
Synopsis: Dr. Chen’s research focuses on the use of advanced MRI for surgical planning and outcome prediction of brain tumor resection. His current project aims to develop MR measurement methods to build a predictive model that simulates the impact of neurosurgery on both functional and structural brain connectomics by utilizing pre-operative imaging.
The goals of the model are twofold: 1) to provide a basis for predicting near- and long-term patient outcome, and 2) to use these predictions in a real-time environment to optimize the surgical plan to the individual patient.

Research Title:: Clinical Translation of Non-Proton MR
We are developing and improving clinical multinuclear MR imaging and spectroscopy for metabolic assessment, cell tracking, and oximetry applications. Current projects include measuring oxidative phosphorylation (fluorine-19), quantifying anaerobic glycolysis (hyperpolarized carbon-13), and determining the fate of adoptively-transferred immune cells (fluorine-19). Our overall research goal is to expand clinical MR beyond standard anatomical imaging to provide cellular information that enables better diagnoses, personalized treatments, and rapid assessments of treatment response.

Research Title: Development of MRI and CT imaging for tracking thermoembolization.
Synopsis: We are investigating thermoembolization as a transarterial intervention for hypervasular tumors.
It consists of a transarterial injection of an acid chloride dissolved in lipid. The resulting tissue insults include: 1) embolization/ischemia, 2) heat, 3) lower local pH, 4) a high local osmolar tissue environment, 5) covalent modification of glycoproteins, and 6) the acid of the acid-chloride can be selected to have anti-tumor drug effects—namely, dichloroacetate has been studied as a drug to inhibit aerobic glycolysis, i.e., Warburg metabolism. I am providing MR and CT imaging methods, to track and characterize thermoembolic injections.
Thus far, we have successfully implemented MR temperature imaging to dynamically track the heat released by the injection of dichloroacetyl chloride. We corroborated that result with temperature probes and pre-/post-injection multi-energy CT. Presently, we seek to demonstrate other MR-based measurements’ utility for measuring changes. In the future, these MR and CT measurements will be compared to pathology and imaging mass spectrometry available to Dr. Cressman’s lab, hopefully providing imaging surrogates for treatment outcomes.

Research Title: Dual-Energy Computed Tomography Temperature Monitoring
Synopsis: My primary focus is the use of Dual-Energy Computed Tomography (DECT) to assess temperature changes in tissue.
Temperature monitoring is particularly important for thermal therapies of malignant disease to ensure treatment of the whole tumor volume, while minimizing damage to the normal tissues surrounding the lesion. I am currently performing preliminary experiments to assess the sensitivity of DECT metrics to changes in the thermal expansion of water and various tissue types and assessing the reproducibility of CT temperature measurements.

Research Title: Constrained Reconstruction Methods
Synopsis:: As a member of the magnetic relaxometry research lab, I have the opportunity to work with a novel technology that estimates the location of target-biology using nanoparticles (MRXTM). My efforts primarily focus on utilizing convex optimization algorithms to model and constrain the acquired signal from the nanoparticles to generate a distribution map with high sensitivity.

Research Title: Evaluation of an Automated Grid Artifact Detection System for Quality Control in Digital Mammography
Synopsis: We’ve developed a system for automatically quantifying the appearance of grid artifacts in mammography images. Retrospective analysis of phantom and clinical images has allowed us to set thresholds for physicist intervention, for specific failure modes in the generator and grid subsystems.
This system has been integrated into our routine QC program, along with automated email alerts, for efficient monitoring of image quality without impacting clinical operations.

Research Title: Simulation and optimization of quantitative methods for hyperpolarized MRI
Synopsis: Hyperpolarized MRI is an emerging imaging technique that can transiently increase the magnetic resonance signal by many orders of magnitude. This additional signal allows for non-invasive metabolic imaging with unprecedented sensitivity.
Metabolic imaging with hyperpolarized MRI has been shown to identify tumor presence, stage, mutational status, and early response to therapy preclinically and could be a powerful resource for personalized cancer management. Hyperpolarized imaging is currently being translated into the clinic with clinical investigations ongoing at multiple sites including MD Anderson. In order to be most beneficial to clinical decisions, the metabolic measurement made by hyperpolarized MRI must be robustly quantifiable, that is result in reliable numeric values. Due to the high sensitivity of the hyperpolarization technique, it is uniquely impacted by multiple detection and tissue parameters that must be properly accounted for during the image acquisition design, reconstruction, and analysis.
Our lab focuses on developing and optimizing the entire hyperpolarized imaging chain using a broad range of model systems from simulation to clinical data. Such a rigorous analysis of the technique will ensure that the measurements made with hyperpolarized MRI are robust enough that they can play a critical role in personalized cancer management.
