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.
