Transesophageal sonography in central bronchial carcinoma.
A new application of transesophageal sonography was tested in eight patients suffering from central bronchial carcinoma. Due to ultrasound technology, a real time investigation is feasible which enhances the diagnostic method of computed tomography (CT) by discriminating between tumour and mediastinal organs which cannot be delineated by CT only. Different sonographic densities and the movement between organ and tumour contribute to the diagnostic accuracy of sonography if operability is questionable due to possible organ infiltration by tumour. The method is limited by the air filled organs (trachea, bronchi), as ultrasound does not penetrate adequately.
