Comparative Study
[Diagnosis of pleural effusions and atelectases: sonography and radiology compared].
In a prospective study it was shown that chest ultrasonography is superior to conventional x-ray diagnosis of recumbent patients in diagnosing pleural effusion and lung atelectasis. In 110 supine radiographs we found a sensitivity of 47% and a specificity of 71% for right pleural effusions and a sensitivity of 55% and a specificity of 93% for left pleural effusions in comparison to 110 sonographic examinations. The results of supine radiographs in detection of atelectasis were less efficient: sensitivity for the right side: 7%; sensitivity for the left side: 13.5%. Hence, the knowledge of chest ultrasonographic diagnosis can improve the interpretation of supine radiographs.

65 patients with penetrating or blunt scrotal trauma underwent scrotal ultrasound. High-resolution real-time sonography was able to differentiate testicular from extratesticular lesions in all cases. ⋯ Diagnosis could be confirmed at operation in 12 cases and by clinical and sonographic follow-up in 8 cases. A heterogeneous parenchymal pattern, contour abnormalities, poorly defined margins and obvious fragmentation of the testicle strongly suggest testicular rupture.
