Radiologists in Europe ramp up testing of AI

Four out of seven commercially available AI algorithms for detecting lung nodules on x-rays performed better than human readers in a recent study.

January 11, 2024

Example chest x-rays from a public test set illustrate algorithm and reader similarities to and discrepancies from the reference standard. A specialized radiologist determined the reference standard score (0, no nodule present; 100, one or more nodules present), and algorithms and human readers provided a probability score between 0 and 100 for each patient of the likelihood that the patient was a nodule case. (A) Radiograph in a man (age, 72 years) with a nodule present (reference standard score, 100) shows a true-positive result based on the average algorithm scores. (B) Radiograph in a man (age, 68 years) without a nodule present (reference standard score, 0) shows a true-negative result based on the average algorithm scores. (C) Radiograph in a woman (age, 64 years) without a nodule present (reference standard score, 0) shows a false-positive result based on the average algorithm scores. (D) Radiograph in a man (age, 37 years) with a nodule present (reference standard score, 100) shows a false-negative result based on the average algorithm scores. Corresponding lateral images and CT scans (when available) for these patients are presented in Figure S2 (supplementary data). The images shown in this figure were part of a public subset and not part of the set on which metrics are reported, which remains confidential for reevaluation in the future. Algorithm scores provided for the images are raw, uncalibrated scores and cannot be directly compared to each other; they are provided for indicative purposes only.

Point-of-care decision support reduces unnecessary CT, MRI imaging

By Kate Madden Yee

A point-of-care, web-based clinical decision support tool shows promise for reducing the incidence of inappropriate CT or MR imaging, patients' radiation exposure, and even carbon emissions caused by unnecessary exams.
