AIUM Lends Support to RSNA's QIBA Project
July 10, 2020
The AIUM supports the RSNA project: 3D Ultrasound Enables Accurate, Noninvasive Measurements of Blood Flow.

This project is about measuring blood flow, such as that to the brain or through the umbilical cord to the fetus. It was organized under one of the biomarker committees from within QIBA (Quantitative Imaging Biomarkers Alliance). With this committee, we were able to assemble many manufacturers of ultrasound scanners and phantoms as well as scientists and physicians at one table and work together on a standardized test for volumetric blood flow. Using this test, we conducted a study at seven different sites and measured volumetric blood flow with three different scanners. We saw that variations between sites could be as low as single-digit percent, which was very encouraging, and that scanners from different manufacturers could make very similar measurements under certain conditions. Based on this study, we think it is possible to move this biomarker toward the clinic, and we are working with manufacturers on implementing volumetric blood flow measurements for diagnostic use. This round-robin study was partially funded by the NIH and organized by the RSNA as a larger initiative for all radiological imaging modalities. The AIUM is providing administrative support for this biomarker committee as well as the newly formed Pulse-Echo Quantitative Ultrasound (PEQUS) biomarker committee.
