Ga-68 ABY-025 PET/CT and F-18 FDG-PET/CT images at baseline with F-18 FDG PET/CT follow-up after two cycles of treatment in biopsy-confirmed HER2-positive disease. (A) Patient with high Ga-68 ABY-025 uptake (SUVmax, 21), who previously received three lines of treatment. F-18 FDG-PET/CT follow-up showed complete metabolic response. (B) Patient with low uptake (SUVmax, 5.4), who previously received three lines of treatment. F-18 FDG PET/CT follow-up showed disease progression (a 68% increase in tumor glycolysis) despite HER2-targeted treatment. (C) Patient with heterogeneous Ga-68 ABY-025 uptake, who previously received seven lines of treatment. F-18 FDG-PET/CT follow-up showed heterogeneous response, with lesions higher in Ga-68 ABY-025 uptake tending to have better response. Arrows indicate biopsy sites.

PET/MRI superior for diagnosing cardiac sarcoidosis
By Will Morton
PET/MRI scans are more accurate for diagnosing cardiac sarcoidosis than established imaging approaches, as well as reduces patient radiation and imaging times.

Images in a 52-year-old woman with cardiac sarcoidosis. Standard-of-care imaging (top row) demonstrates a perfusion defect on SPECT images (top left) and corresponding FDG radiotracer uptake on PET/CT image (top right) at the interventricular septum (green arrows). On combined F-18 FDG-PET/MRI (bottom row), there is nodular late gadolinium enhancement (LGE) at the interventricular septum (orange arrows) with corresponding FDG uptake (blue arrows).
