Metrology papers

Under the direction of RSNA, three QIBA Metrology Working Groups were formed to discuss terminology for metrology concepts, algorithm comparisons and technical performance of an imaging assay.

The all-volunteer groups embraced the challenge to standardize across these concepts and reduce ambiguity regarding the terms and methodology used for measuring, describing and comparing various components of imaging tests.

The efforts of the QIBA Metrology Working Groups establish standardized terminology for use in research and clinical practice to meet the alliance’s overall goal to improve the value and practicality of quantitative imaging biomarkers by reducing variability across devices, patients and time.

Based on the committees’ work, the following six manuscripts were published in either Radiology or Statistical Methods in Medical Research:
