| 摘 要： | 目的：初步探讨能谱CT的宝石能谱成像（gemstone spectral imaging,GSI）模式和MRI在手肌腱正常解剖以及基本病变中的应用。方法：30例手肌腱病变患者,手肌腱正常,因其他疾病需手部CT扫描者5例作为解剖对照,分别行GSI和MRI检查,通过能谱分析软件,选择适宜单能量值（KeV）,将混合能量图像转换为单能量图像,运用多种图像重组方式,观察能谱CT图像,并和MRI对照分析。结果：GSI能显示肌腱的形态,连续走行,止点,特别在显示肌腱,骨骼,肌肉的三维空间关系上,较MRI有优势。对于肌腱断裂,增粗,缺失,受压的显示,GSI与MRI比较,,差异无统计学意义（P〉0.05）。对肌腱粘连、变性、腱鞘病变的显示不如MRI清晰,差异有统计学意义（P〈0.05）。结论：宝石能谱CT在手部肌腱解剖及病变显示方面有较大应用价值,能为临床提供有力的影像学支持;而MRI在肌腱变性、粘连及腱鞘病变中,优势明显。

| Abstract: | Objective:To perform a preliminary investigation of the value of gemstone spectral imaging(GSI),a mode of spectral computed tomography(CT),and magnetic resonance imaging(MRI) in hand tendon anatomy and disease diagnosis.Methods:Thirty patients who received either GSI or MRI were enrolled.Mixed-energy images were inverted to single-energy ones in appropriate single-energy value(KeV) using energy spectrum software.These images were compared and analyzed with multiple image reconstruction modes and read to pre... |
