肺癌历来依据临床症状、体征、X线、纤维支气管镜及细胞学检查诊断,但均不能直接显示病灶的全面情况。我院从1989年以来应用B超探查胸腔肿物54例。其中肺癌40例,结果表明声像图具有一定特点。其诊断敏感性为98％。B超对有胸水,病灶小,周围型、X线肿块不明显肺癌更具有诊断价值。所以它是诊断肺癌最主要的仪器。现总结报告如下。 1 资料和方法:胸腔肿物54例(男41例、女13例),年龄19岁一68岁。其中肺癌40例,分别经纤维支气管镜、细胞学及手术证实,有3例肝转移,2例心包及胸腔转移,1例腹腔转移。采用仪器是日立EUB—240线阵、东芝22A超声扫描仪。探头频率3.5MHz。如有病变用录像
Lung cancer has historically been diagnosed on the basis of clinical signs, signs, X-rays, fiberoptic bronchoscopy, and cytology, but it does not directly show the overall condition of the lesion. Since 1989, 54 cases of thoracic masses have been examined by B ultrasound in our hospital. Among them, 40 cases of lung cancer showed that the sonogram had certain characteristics. Its diagnostic sensitivity is 98%. B ultrasound has pleural effusion, small lesions, peripheral type, X-ray mass is not significantly more diagnostic of lung cancer. So it is the most important instrument for diagnosing lung cancer. The summary report is as follows. 1 Materials and methods: 54 cases of thoracic masses (41 males and 13 females) aged 19 to 68 years old. Among them, 40 patients with lung cancer were confirmed by fiberoptic bronchoscopy, cytology, and surgery. There were 3 cases of liver metastases, 2 cases of pericardial and thoracic metastases, and 1 case of celiac metastases. The instrument is Hitachi EUB-240 line array, Toshiba 22A ultrasound scanner. Probe frequency 3.5MHz. If there is video for lesions
