RBMA Hill Day underscores importance of radiology advocacy
The U.S. Centers for Medicare and Medicaid Services is the single largest payor for healthcare in the U.S., and as government moves to cut costs and improve value for the public healthcare dollar, the ripple effects are felt throughout radiology. Advocating for radiology during these times of change is a job for everyone in the field, not just radiologists.

Post-neoadjuvant chemotherapy (NAC) MRI scans in a 66-year-old woman with invasive breast cancer show a lesion that appears fragmented in the first postcontrast axial T1-weighted image (arrow in A) but becomes more conspicuous and homogeneous in the last delayed phase (arrow in B). Despite these visual differences, response classification was identical between abbreviated and full diagnostic MRI. Pathologic analysis confirmed a partial response with residual invasive carcinoma.

(A) Averaged parametric images of F-18 SynVesT-1 BPND values and (B) F-18 FDG SUVR (60–90 minutes) values overlaid on anatomical (T1) images in MNI space show group differences between behavioral variant frontotemporal dementia (top) and healthy controls (middle). The color scale represents (A) BPND and (B) SUVR values. On the bottom, average z-score maps were generated to visualize regional reductions in F-18 SynVesT-1 BPND and F-18 FDG SUVR in bvFTD relative to healthy controls. For each voxel, z-scores were calculated as z = (bvFTD−meanHC )/SDHC. Negative z-scores indicate lower synaptic density or glucose metabolism in the bvFTD compared with controls in the regions. BPND, non-displaceable binding potential; bvFTD, behavioral variant frontotemporal dementia; F-18 FDG, F-18 fluorodeoxyglucose; MNI, Montreal Neurological Institute; SUVR, standardized uptake value ratio.
