通过对15例肺内孤立性结节的HRCT(高分辨CT扫描)及动态增强扫描的观察,对判断肺内孤立性结节的良、恶性具有重要的临床意义。发现下列征象对恶性病变有帮助:结节边缘征象(分叶征、毛刺棘突征)、结节内部征象(空泡征、空洞)、肺结节并肺门纵隔淋巴结增大。良性征象为:小的卫星灶、均匀致密的钙化、结节边缘光滑规整、<3cm结节内如出现空洞都以良性病变为多。另外追踪观察,结节的倍增时间对判断病变的性质价值较大。
Through the observation of 15 cases of solitary pulmonary nodules HRCT (high resolution CT scan) and dynamic contrast-enhanced scanning, it has important clinical significance to judge the benign and malignant solitary pulmonary nodules. The following signs were found to be helpful in the diagnosis of malignant lesions: borderline signs (lobar lobes, spiny prickles), internal signs of nodules (vacuoles, voids), enlarged pulmonary nodules and hilar mediastinal lymph nodes. Benign signs are: a small satellite stove, uniform and dense calcification, nodules smooth edge, if less than 3cm nodules benign lesions are more. In addition to follow-up observation, doubling the nodule time to determine the nature of the lesion of greater value.
