Katrina hammers radiology staff at Mississippi hospital

The radiology department administrator at a Mississippi hospital is calling for volunteers to assist his staff of radiologic technologists, many of whom are exhausted after working multiple shifts in the aftermath of Hurricane Katrina. The hurricane has overwhelmed the hospital's RT staff, which is caring for the sick and injured even as their own lives have been upended by the disaster.

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.

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

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.
