Gerald F. Abbott Adjunct Associate Professor of Diagnostic Imaging

Dr. Abbott is a graduate of Cornell University Medical College and completed residency and fellowship training at New York Hospital in radiology and neuroradiology, respectively. He subsequently received fellowship training in thoracic radiology at Massachusetts General Hospital. He is on the visiting faculty at the Armed Forces Institute of Pathology(AFIP) in Washington DC and has published scientific series from the Archives of the AFIP. His current research efforts are focused on the chronic effects of smoke inhalation. He is the co-author of a Teaching Atlas in Chest Imaging and is a frequent lecturer at national and international meetings in thoracic imaging.

Research Areas

research overview

Gerald Abbott, M.D., is currently conducting a study of the chronic effects of smoke inhalation in a group of survivors of a catastrophic night club fire. The study utilizes high-resolution CT scans of the lungs obtained during inspiration and expiration in order to detect evidence of small airway obstruction and other changes in the lungs that are related to smoke exposure.

Dr. Abbott is also a principal investigator in this region for the National Lung Screening Trial (NLST), a study that is designed to prove whether or not the early detection of lung cancer by CT has a beneficial effect on the rate of mortality from lung cancer.

research statement

Smoke Inhalation Study:
Volumetric high-resolution CT studies are performed during inspiration and expiration and analyzed for evidence of air-trapping and for the presence of other sequelae of smoke inhalation: bronchiectasis, bronchiolitis obliterans, centrilobular nodules, pneumatoceles, parenchymal scarring.

National Lung Screening Trial (NLST):
Subjects are randomized to receive an annual chest radiograph or a low-dose CT scan as screening examinations to detect lung cancer. All subjects have a minimum of 30-pack-years smoking history. Nodules are evaluated by follow-up CT scans at 3, 6, 12, and 24 month intervals, and those nodules determined suspicious for lung cancer are biopsied. The results of this study will be compiled from 15 study centers throughout the nation.

funded research

National Lung Screening Trial (NLST), Site Principal Investigator
Sponsored by the National Cancer Institute (NCI) and the American College of Radiology Imaging Network (ACRIN)
Accrual completed 2-2004. Rhode Island Hospital (RIH) site: 826 subjects (50,000 nationally)
Trial period began 2002, Trial completion 2009
Funding: National: $40,000,000; Local: $3,375,000
The National Lung Screening Trial seeks to determine if the early detection of lung cancer affects lung cancer-related mortality. Subjects are randomized to multi-detector CT scanning or chest radiography.

Seed Grant: "Chronic Effects of Smoking Inhalation on Inspiratory and Expiratory HRCT".
Rhode Island Medical Imaging Seed Grant program, Principal investigator
Funding: $15,000. Chronic effects of smoke inhalation—a funded study to determine the long-term effects of acute smoke inhalation. The study cohort consists of survivors of the Station Nightclub Fire (February 21, 2003; West Warwick, RI) that resulted in 100 fatalities. HRCT (inspiratory & expiratory) and PFTs are being obtained and correlated with duration and intensity of exposure.
