近十年来超声诊断仪性能大大提高,特别在使用最新的机械扫描扇形实时灰阶显象仪中 对原发性肝癌诊断可获得较清晰而又准确的癌瘤声象图。Toylor等应用同位素肝扫描显示“冷区”肝囊肿、脓肿、原发和转移性癌瘤的病例,并全部辅以灰阶超声断层扫描检查,其准确率达88％。目前已广泛应用于临床。 In the past ten years, the performance of the ultrasound diagnostic apparatus has been greatly improved. In particular, in the use of the latest mechanical scanning fan-shaped real-time gray-scale imager, a clearer and more accurate acoustic image of cancer is obtained for the diagnosis of primary liver cancer. Toylor et al. applied isotope liver scans to show “cold zone” cases of hepatic cysts, abscesses, primary and metastatic carcinomas, and all were supplemented with gray-scale ultrasound tomography scans, with an accuracy rate of 88%. Has been widely used in clinical.
