RSNA organized the Quantitative Imaging Biomarkers Alliance (QIBA) in 2007 to unite researchers, healthcare professionals, and the industry to advance quantitative imaging and the use of imaging biomarkers in clinical trials and clinical practice. The Society is committed to transforming patient care by making radiology a more quantitative science.
The initiative includes:
Quantitative imaging is the extraction of quantifiable features from medical images for the assessment of normal or the severity, degree of change, or status of a disease, injury, or chronic condition relative to normal.
Quantitative imaging develops, standardizes, and optimizes:
These features permit the validation of accurately and precisely obtained image-derived metrics with anatomically and physiologically relevant parameters, including treatment response and outcome, and the use of such metrics in research and patient care.
QIBA seeks to improve the value and practicality of quantitative imaging biomarkers by reducing variability across devices, patients, and time.
RSNA’s QIBA initiative has advanced through the generous commitment of volunteer committee members from academia, medical device, pharmaceutical and other business sectors, and government.
There are four modality-based Coordinating Committees, including Q-CT, Q-MR, Q-NM, and Q-US. Ten Biomarker Committees include CT Volumetry, Lung Density, PDF-MRI, fMRI, MRE, DSC, FDG-PET/CT, PET-Amyloid, SPECT and Ultrasound Shear Wave Speed. Each committee has specific responsibilities for its respective modalities or disease-based approach, and is open to interested persons.
