Objective To quantitatively evaluate the feasibility of material decomposition(MD) for the differential diagnosis of osteolytic bone metastases and Schmorls nodes using Spectral Imaging.Methods Fifteen pathologically proven malignant tumor patients with CT,MR and PET-CT imaging confirmed osteolytic bone metastases(36 lesions) and 18 patients with 22 Schmorls nodes underwent dual-energy spectral CT imaging using a high definition CT (Discovery CT750 HD,GE).We reconstructed 40-140 keV axial image data sets with 1.25 mm slice thickness.

目的:血友病性关节病由于关节畸形或强直而严重影响患者的生活质量和身心健康。患者如果能得到早期诊断和合适治疗,将会避免或延缓关节畸形的发生,因此,临床需要对血友病性关节病进行正确的诊断和评估,影像检查在血友病性关节病的诊断和评估方面起着重要的作用。由于近年来多种影像检查方法应用于血友病性关节病,但最常见的三种影像检查方法是X线、CT和MRI.以往研究主要集中于X线和MRI,尤其是近几年比较关注MRI
