能谱CT定量分析对孤立性肺结节/肿块鉴别诊断的初步研究
Preliminary study of spectral CT imaging in the differential diagnosis of solitary pulmonary nodules and masses
摘要
Abstract
Objective To investigate the diagnostic value of spectral CT imaging in differentiating of pulmonary nodules and masses.Methods 129 patients with pulmonary nodules or mass received triphasic pulmonary enhanced CT scan in GSI mode on Discovery CT750 HD.All raw data was sent to AW4.6 workstation and processed by the software of GSI work station.Normalized iodine concentration (NIC), CT value at 40 keV and slope rate of spectral curve were measured and compared.All the parameters were analyzed among three phases.Results 125 cases were proved by pathology through surgery or bronchoscopy, 4 cases were proved by follow-up (pneumonia 19, lung cancer 99 and tuberculosis 11).NIC, CT value at 40 keV and slope rate of spectral curve were found the highest in pneumonia, and lowest in tuberculosis.The above mentioned parameters were found significant difference in the three parameters either between tuberculosis and pneumonia or between tuberculosis and lung cancer in three phases.There was significant difference in NIC and CT value at 40 keV between pneumonia and lung cancer only in delayed phase.Conclusion Spectral CT imaging demonstrated the potential in diagnosing of pulmonary nodules and masses.关键词
