Radiologists in Europe ramp up testing of AI
By Will Morton
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.

PCCT overcomes image limitations for stenosis quantification on CCTA
By Kate Madden Yee
Photon-counting detector CT (PCCT) with virtual monoenergetic imaging reconstruction shows promise for quantifying stenosis with coronary CT angiography (CCTA).
January 10, 2024
82-year-old man with calcified stenosis in left main artery who underwent coronary CTA by PCCT. Curved multiplanar reformatted images at varying virtual monoenergetic imaging (VMI) levels (40-140 keV) show stenosis at each level. Percent diameter stenosis (PDS) decreased from 92.5% at 40 keV to 53.1% at 140 keV. Extent of calcium blooming artifacts decreased from 100% at 40 keV to 72.3% at 140 keV.

FAPI-PET predicts treatment response in patients with rheumatoid arthritis
By Will Morton
FAPI radiotracer uptake on PET/CT imaging may be a biomarker for identifying early responders to rheumatoid arthritis (RA) treatment.
January 9, 2024
Representative Ga-68 FAPI-04 and F-18 FDG-PET/CT images of responders at three month follow-up. Patient #11 was a 50-year-old man with 28 affected joints detected in PET/CT. Joint activity decreased after treatment with Tripterygium wilfordii, methotrexate, adalimumab, and prednisone. In patient #8 (a 65-year-old woman), Ga-68 FAPI-04 PET/CT showed 12 affected joints. Joint activity decreased from baseline after three months of treatment with Tripterygium wilfordii and methotrexate.
