title: [Roentgenography and real-time ultrasonography in the diagnosis of pulmonary and mediastinal lesions].
abstract: A correlative study of 65 proved cases with pulmonary or mediastinal lesions was made between roentgenography, ultrasonography and a part of surgically removed specimens. It included 41 cases of intrathoracic spherical lesions, 20 cases of mediastinal lesions and 4 cases of pneumonia. The result suggested that ultrasonography is a useful and feasible adjunct in the diagnosis of the intrathoracic lesions. Many of these lesions were suitable to ultrasonography, which may be helpful in determining the nature and location of them. In this preliminary study different ultrasonographic characteristics were found between adenocarcinoma and squamous cell carcinoma, perhaps being correlated with homogeneity of the texture of these tissues. However, a small deep lesion or a small central necrosis may not be detected by ultrasonography. For such a lesion it must be combined with roentgenography to improve the diagnostic accuracy.
