SIR Foundation awards $1.5 million in special research grants

Four projects receive funding for high-impact interventional radiology research to further knowledge of existing IR therapies or lead to breakthrough IR therapies that improve patient outcomes

FAIRFAX, VA (Dec. 5, 2022)—The Society of Interventional Radiology (SIR) Foundation has awarded $1.5 million in grant funding to four projects exploring embolization and interventional oncology research. 

The funding supports high-impact interventional radiology (IR) research that will further knowledge of existing IR therapies or lead to breakthrough IR therapies that improve patient outcomes. Two awards fund research using structured reporting and registry-based approaches, while the remaining awards fund early and conceptual-stage IR research projects that are multispecialty. 

“Data supporting IR therapies are essential for expanding patient access to IR and through this special grant funding these exemplary studies will help to achieve that goal,” said SIR Foundation Chair Theresa M. Caridi, MD, FSIR, associate professor and division director of interventional radiology at the University of Alabama at Birmingham. “SIR Foundation is grateful for the support of our donors and corporate partners, which allows us to meet our mission to foster IR research and help our members care for their patients.”

The following studies were selected through a competitive review process.

Special Funding Grant—General

  • Correlations of Y-90 Tumor Absorbed Dose to Histopathologic Changes and Local Tumor Control; Constantinos T. Sofocleous, MD, PhD, FSIR, from Memorial Sloan Kettering Cancer Center  
  • Development of a Novel Humanized Patient-derived Xenograft Model of Hepatocellular Carcinoma (HCC) for Interventional Oncology (IO); Terence Gade, MD, PhD, from the University of Pennsylvania 

Special Funding Grant—Standardized/Structured Reporting

  • Prospective, Multicentric Registry of Pulmonary Arteriovenous Malformation (AVM) Embolization; Clifford R. Weiss, MD, FSIR, from Johns Hopkins University 
  • Genetic Subtyping to Enable Precision-guided Interventions for Hepatocellular Carcinoma (HCC); Gregory J. Nadolski, MD, from the University of Pennsylvania
