DESCRIPTION

A Practical Algorithmic Approach to the Diagnosis and Management of Solitary Pulmonary Nodules. 背景. 孤立性肺部结节（ solitary pulmonary nodule ， SPN ）的定义：影像学显示的直径 ≤3cm 、边缘 2/3 以上被肺组织包绕的肺部高密度影，需除外淋巴结、肺不张及阻塞性肺炎。 胸片检查可发现 0.09%-7% 的 SPN 。胸部 CT 扫描则可发现 8%-51% 的 SPN 。 恶性肿瘤的比例为 1.1%-12% 。. 鉴别诊断. 感染性疾病. 新生物. - PowerPoint PPT Presentation

• Pretest ProbabilitySPNAge is the patient's age in years, smoke = 1 if the patient is a current or former smoker (otherwise, smoke = 0), diameter is the diameter of the nodule in millimeters, spiculation = 1 if the edge of the nodule has spicules (otherwise, spiculation = 0), and location = 1 if the nodule is located in an upper lobe (otherwise, location = 0).
