VolparaAnalytics assists in quality assurance by monitoring and recording critical elements of the breast imaging process, and then generating key imaging performance metrics to help understand the performance of technologists, readers and mammography machines.
For each image received, VolparaAnalytics automatically extracts information about the x-ray physics parameters used, records mammography and technologist identifiers, and computes various novel metrics from that data, including volumetric breast density and pressure. Real-time alerts and reports can demonstrate, for example, whether one technologist is compressing too much, or if one mammography unit is operating differently to the others. This comparative information can help determine whether additional training or re-calibration is required.
“The measurements have already proven effective in identifying issues at several facilities and have enabled us to resolve them in a timely manner. This is a very useful tool and the volumetric context is critical to understanding how a particular unit functions,” said
“Imaging performance metrics, such as average force, can only be properly interpreted in context of the volumetric characteristics of the patient population. For example, one site might apply far more force because the breast size is higher, a fact that becomes very evident when you consider pressure applied, not force,” said
In the study “Practitioner compression force variation in mammography: A 6-year study” recently published in the
In another recent study “Screening mammography recall rate: does practice site matter?”, recently published in Radiology, Rothschild et al questioned “the utility of a universal recall rate goal and suggest that targets have to be adjusted on the basis of local population factors.” With VolparaAnalytics, clinics can now consider their recall rates in the context of knowing their volumetric context. According to Highnam, “a particular site might have far more recalls than another because the patient population at that site is far denser. Similarly, a radiologist who primarily reads fatty mammograms from a more obese neighborhood may seem to outperform another radiologist whose patients are predominately younger or slimmer women with dense breasts.”
