Real-life Performance Evaluation of the LiFlow X-ray Platform

The LiFE study consists in retrospectively interpreting the TAP scans of patients who have agreed to take part in the study at two separate times, once without the LiFlow tool and once with it, at least 8 weeks after the scan date. To avoid any memory effect, a washout period of 8 weeks will be observed between these two interpretations. The study will involve 10 radiologists and 400 patients. Each scan will be interpreted twice by the same doctor (with and without the LF tool). During the second retrospective interpretation, the radiologist will assess the impact of of the additional lesions discovered by LiFlow on the patient's therapeutic management. The notion of change in management is defined by a change in treatment, such as a change in surgical technique, a change in chemotherapy or an indication for a treatment not initially planned. In addition, for these lesions, a gold standard will be obtained (an opinion from one or two other radiologists and/or other characterization imaging and/or biopsy/histology and/or follow-up of the lesion).

The aim of the study is to validate the time saved on interpretations and reports, and to improve the accuracy of TAP scan interpretation.
