B超与X线检查脓胸的对比分析

Comparative Study of B-mode Ultrasonography and Radiography in diagnosis of Pyothorax

本文报告了经手术、穿刺病理证实46例脓胸(53个病灶)的B超与X线检查对比结果。B超符合率90.6%,X线为79.3%。＜3cm以下的脓胸病灶B超检出敏感性为81.9%,与X线检查比较(P ＜0.01),差异非常显著;＞3cm以上两者无显著性差异(P＞0.05),提出了本病为分隔型、类实型、混合型三种声像图类型,讨论了B超与X线检查本病的优点和不足。认为两种检查结合有助于脓胸的诊断及鉴别诊断,可减少误诊及漏诊。

This paper repots a comparative study of B - mode ultrasonography and radiography in 46 cases of pycthorax with 53 lesions,which are proved by operation or thoracentesis.The coincidence rate of ultrasonography is 90. 6% and that of radiography is 79. 3%. With small lesions (<3cm), the sensitivity of ultrasonography (81. 9%) is much higher than that of radiography (P<0. 01). With big lesions (>3cm), the former is not very different from the latter(P>0. 05). The ultrasonogram is divided into three types: septum -lide,mass - like and the mixed. With the discussion of advantages and disadvantages, we conclude that the combination of the two methods is beneficial to the diagnosis and differentiation of pyothorax with a decreased rate of misdiagnosts and overlooking.
