DFP Profile

DFP NAME:

SAR Liver Fibrosis DFP

MISSION:

To promote understanding and research in the common yet misunderstood disease of liver fibrosis.   

DFP GOALS:

• To educate practicing radiologists about the disease process and precursors (such as viral hepatitis, hemochromatosis, and steatohepatitis) and the possibilities for early diagnosis.
• To create a uniform reporting system and terminology in collaboration with hepatologists.
• To promote the development and use of imaging techniques for the diagnosis and monitoring of liver fibrosis. Imaging tests include US elastography/ARFI, MR elastography, diffusion and perfusion imaging, dual energy CT.
• To develop guidelines for optimal early diagnosis, management and follow up of patients along the spectrum of disease. Guidelines will be informed by a respected multi-disciplinary team of radiologists, hepatologists and pathologists, and account for variability in practice and resources among different facilities. Guidelines will include acceptable cut-off values and ranges for quantitative imaging techniques.
• To advance research of imaging techniques by creating an inter-disciplinary and multi-institutional team that will initiate prospective studies of imaging techniques and assess their reproducibility.
• To define the role of imaging in the early diagnosis and follow up of liver fibrosis. Evaluation will consider the wide use of serum fibrosis panels (including APRI, FIB4, Fibrotest, and PGA) and newer potential markers for NASH and practical use of imaging tests in daily practice.
• To promote patient education about the importance of early diagnosis and follow up of fibrosis and its precursors.
• To promote referring colleague education regarding available imaging methods for fibrosis diagnosis and monitoring.
