Utility of photon-counting CT localizer radiograph in opportunistic bone densitometry.
Purpose Dual-energy X-ray absorptiometry (DXA) is the clinical gold standard for areal bone mineral density (aBMD) assessment for the detection of osteoporosis. The advancement of photon-counting CT (PCCT) provides an opportunity to use spectral localizer radiographs (LRs) for opportunistic aBMD assessment. This study...
