肺外周肿块的灰阶超声表现──附150例分析

GRAY SCALE ULTRASONOGRAPHIC FINDINGS OF PERIPHERAL LUNG MASS

本文报道了在X线检查定位下,用B型超声检查了150例经病理证实的肺外周肿块,包括肺癌,转移癌,良性瘤,炎性假瘤及结核球。X线和超声诊断正确率分别为69.3％和70.0％,但两种检查相结合诊断正确率为91.3％。作者将声象图与X线所见及病理改变作了对照观察。本文还讨论了超声诊断和鉴别诊断的价值和限制。

Under the localization of roentgenograph, 150 patients with pathologically evidenced peripheral lung mass were studied by B-mode Ultrasonograpy. These patients were suffered from lung cancer, metastatic lung cancer. beuign tumor,inflammatory pseudotumor and tuberculoma. The diagnostic accuracy of Roentgeno-graphy and Ultrasonography were 69.3% and 70.0% respectively, but the diagnosticaccuracy of 91.3% couid be obtained with the combined use of both methods. A comparative description of Ultrasonographic images and Roentgenographicfindings, and their relation to pathological change were described. The ualueand limitation of Ultrasonographic diagnosis and differential diagnosis were alsodiscussed.
