目的探索新的诊断方法,减轻病人经济负担。资料与方法超声检查前病人均做常规胸部摄片,根据X线片提示的病变部位选择透声窗,用不同的体位沿肋间探查,以图象清晰为准。结果22例病人2例未显不肿瘤回声,显示并发症的有20例,肿块超声的声像图为:中低回声的实质性光团,呈圆形,类圆形、可有分叶,边缘不整,多有回声不均的声晕,后壁回声有衰减。结论肺癌的诊断最直接的方法是普通放射线,CT的普及使肺癌及并发症的准确诊断有了绝对优势,但费用相对较高,而普通放射线疑诊的病例,正是超声检查的适应症,它补了放射线的不足,且又显示了本身的优势,超声的不足是适应症比较狭窄。的些肿块放射线已经明确诊断,而超声因为没有它所必须的透声窗而无法应用。 Objective To explore new diagnostic methods to reduce the economic burden on patients. Materials and Methods Before the ultrasound examination, all the patients underwent conventional chest radiography. The acoustic window was selected according to the lesion site indicated by the X-ray film, and probed with different body positions along the intercostal space. The image should be clear and accurate. Results Twenty-two patients showed no tumor echo in 2 cases and 20 cases showed complications. The ultrasonography of the tumor was a substantial light mass with low or moderate echogenicity, which was round and round, Edge is not the whole, more echo uneven sound halo, echo attenuation of the posterior wall. Conclusion The most direct method of diagnosis of lung cancer is radiotherapy. The popularity of CT has an absolute advantage in the accurate diagnosis of lung cancer and complications, but the cost is relatively high. However, the cases of common radiological suspicion are the indications of ultrasound examination. It makes up for the lack of radiation, and has shown its own advantages, the lack of ultrasound is more narrow indications. Radiographs of some of the masses have been clearly diagnosed, and ultrasound can not be used because it is not necessary for the translucent window.
