About Us

The Massachusetts General Hospital Imaging Trials Center (MITC) is an Academic Research Organization (ARO) that enhances clinical imaging research by providing scientific and informatics expertise to foster, design, conduct, and support clinical trials.

The primary goals of MITC are to facilitate clinical trials for assessment of medical and device therapies, generate evidence that compares the benefits and harms of alternative management strategies, determine the value of diagnostic imaging in patient management, and find innovative solutions for improved access and distribution of image data collected during clinical trials.

The MITC consists of several cores to assist with each component of clinical research:

  • Imaging Core
  • Informatics Core
  • Education Core
  • Clinical Trial Coordination Core

By bringing together multidisciplinary imaging and non-imaging faculty, the MITC aims to facilitate a more efficient use of administrative and scientific resources within radiology, and ultimately ensure a faster translation of novel methodology that has been proven to be effective into clinical practice. The MITC also aims to enable faculty to accelerate their translational and clinical research.

PROMISE – Improving Diagnostics & Treatment for Heart Disease
Udo Hoffmann, MD, MPH, Director of CVIC Lab at Massachusetts General Hospital is leading the Diagnostic Core component of a first-of-its-kind trial funded by the National Heart, Lung and Blood Institute. PROMISE (PROspective Multicenter Imaging Study for Evaluation of Chest Pain) seeks to identify the best diagnostic approach for evaluation of chest pain in subjects with chronic stable angina and a low to intermediate risk of coronary heart disease.


Group Members

Dr. Udo Hoffmann, MD, MPH – Director of the MITC and Director of Education

Dr. Hoffmann, is a clinical cardiac radiologist with over ten years of experience in noninvasive cardiovascular imaging. He received his MD from the Medical School at the University of Leipzig, Germany and received an MPH from the Harvard School of Public Health. He completed his residency in radiology at the University of Vienna, Austria, and is an Associate Professor in Radiology at the Harvard Medical School. He was the American Roentgen Ray Society, Elio Bracco Scholar in 2005. He is also the Director of the MGH Cardiac MR PET CT Program. He has conducted several NIH-sponsored and industry-supported studies, and leads the Imaging Core Lab of the Framingham Heart Study. His research initially focused on the feasibility of cardiac CT for the detection of coronary stenosis and assessment of atherosclerotic plaque. More recently, he has built a multidisciplinary research team to systematically assess the clinical utility of novel imaging technologies. His research has resulted in over 100 publications to date.

Dr. Garry Choy, MD – Director of Informatics of MITC

Dr. Choy is a clinical radiologist with expertise in cardiothoracic, abdominal, and emergency imaging. His academic and research interests are in the areas of medical informatics, teleradiology, healthcare delivery systems, and global health. He brings significant information technology expertise to MITC with prior experience in development of web-based learning tools, online collaboration platforms, and telemedicine platforms.  Dr. Choy also is co-founder and serves additional leadership roles at the MGH Imaging Global Health Programs and International Radiology Exchange. He also currently leads development and efforts of the MGH Radiology Department’s second opinion service. He received his MD from the Albert Einstein College of Medicine, Yeshiva University and BS from Columbia University. In addition, Dr. Choy also attended Stanford University and earned a Masters in Management Science & Operations Research.
