Total brain volume (TBV) is an important marker of brain health with aging, but its measurement requires resource-intensive MRI. We examined whether DXA-derived head composition can estimate MRI-derived TBV in 314 middle-aged and older adults, and found that it provides a practical approximation with good calibration.<\/p>\n
