作者对163例(男94例,女69例,年龄22～78岁,平均63岁)直径在6～40mm球形肺结节进行CT平扫及增强检查,测量肺结节增强程度是否直接与肿瘤的恶性程度和结节的血供有关。对碘过敏的病人、肌酐高于1.5mg/dl、结节有偏心钙化和绝经妇女均不列入研究。使用低渗透压非离子型碘对比剂,以2ml/s的速度用压力注射器静脉内注射100ml对比剂。每一层面均保持准确的相同程度的吸气或呼气。兴趣区建立在结节处,超越结节周围不多于1～
The author of 163 cases (94 males and 69 females, aged 22 to 78 years, mean 63 years) diameter 6 ~ 40mm spherical pulmonary nodules CT scan and enhanced examination to measure whether the enhancement of lung nodules directly with the tumor The degree of malignancy and nodules of the blood supply. Patients with iodine allergy, creatinine higher than 1.5mg / dl, nodular eccentric calcification and menopause women were not included in the study. Using a hypotonic non-ionic iodine contrast agent, 100 ml of the contrast agent was injected intravenously with a pressure syringe at a rate of 2 ml / s. Each level maintains the same level of inspiration or exhalation. Interest area is established at the nodules, beyond the nodules around no more than 1 ~
