Short communication: spinal bone density measured with a 5 s scan.

摘要: Absorptiometry provides a convenient, non-invasive method of measuring bone mass in the skeleton with high precision and low radiation dose to patient (Tothill, 1989). Dual photon absorptiometry (DPA) based on radionuclide source 153Gd was developed for mineral density (BMD) at clinically important sites spine hip (Wilson & Madsen, 1977). Recently, dual X-ray (DXA) has superseded DPA (Cullum et al, Compared DPA, DXA advantages improved (coefficient variation 1% spinal compared 2–3% DPA) shorter scanning times (6–8 min 20–30 (Sorenson Use an tube instead eliminates problems associated radioactive decay (Lindsay 1987). In most recent development technology least two manufacturers have introduced scanners fan beam configuration coupled multidetector head ...
