本文报告了采用彩色多普勒超声诊断仪检查的26例限局性膈膨升病例,并分析限局性膈膨升的超声检查方法、声像图特征、鉴别诊断及X线与超声诊断限局性膈膨升的利弊。认为限局性膈膨升有其独特的超声声像图特征,超声对该病的诊断具有简便、迅速、准确的优点。如能结合X线检查,可进一步提高其准确性。 This article reports the use of color Doppler ultrasound examination of 26 cases of limited diaphragm diastasis cases, and analysis of the limitations of diaphragm diastolic ultrasonography, sonography features, differential diagnosis and X-ray and ultrasound limited diaphragm Pros and cons of inflation. That limit the expansion of the diaphragm diaphragms have their own unique features of ultrasonography, ultrasound diagnosis of the disease has a simple, rapid and accurate advantages. If combined with X-ray examination, can further improve its accuracy.
