  Objective: To explore the feasibility of using hydroxyapatite (HAP) measurement based on the material decomposition in dual-energy spectral CT imaging to evaluate bone mineral density (BMD). Methods: 247 patients (aged 16 to 97 years, 156 males and 91 females) who underwent both unenhanced and contrast-enhanced (arterial, venous and delayed) phase abdominal dual-energy spectral CT were retrospectively collected. Patients were divided into four groups according to their ages: group A (<30 years, n=40), group B (30-49 years, n=90), group C (50-69 years, n=73) and group D (≥70 years, n=44). HAP densities of trabecular bone of the third lumbar vertebrae in four phases were measured on the HAP material decomposition images using HAP-Iodine as the basis material pair and recorded. HAP as function of age was established and measu.. Read More»
