简介:摘要:计算机专业课程的设置是教改的重点和核心任务,而教学方法的改革是实现为社会主义建设提供专业技术实用型人才的根本保障。只有将二者有机地结合起来,才能培养出高素质、高技能、多层次的职业计算机应用技术人才,从而更好地满足社会对人才的需求。
简介:摘要目的分析胸部X射线平片检查和胸部CT扫描检查在胸壁结核患者临床诊断过程中的应用价值。方法择取2005年1月-2015年12月期间我院收治的胸壁结核患者31例作为本次研究对象,全部患者均经由手术治疗和穿刺活检确诊为胸壁结核,针对全部患者行胸部X射线平片检查和胸部CT扫描检查,针对17例患者实施胸部增强CT扫描检查,系统分析全部患者的影像学检查结果。结果31例患者在胸部X线检查中发现肋骨骨质破坏患者9例,在胸部CT扫描检查中发现肋骨骨质破坏患者11例,胸部CT扫描检查中发现肋骨近旁软组织肿块患者31例但在胸部X线平片检查中未发现,26例患者的肿块性病理组织在胸部CT扫描检查视野下呈现了边缘区域密度数值较高且中央区域密度水平较低现象,其中有15例患者观察到表征明显的边缘强化现象,3例在胸部CT平扫条件下显示多发性低密度现象患者在胸部增强CT检查条件下呈现显著的密度升高现象,且其扫描视野区域内部的众多低密度灶具有显著清晰的观察特征,4例患者呈现出均匀的低密度特征。胸部扫描检查条件下发现有11例患者出现纵膈、肋间或者是腋窝位置的淋巴结组织肿大症状,而在胸部X射线平片检查条件下未发现这一现象。结论胸部X线平片检查和胸部CT扫描检查在胸壁结核诊断中均具有各自的影像学特点,引入胸部增强CT扫描能够显著提升临床诊断的准确性。
