We describe the sonographic findings of nasal fracture in children, and we evaluate the diagnostic value of sonography as compared with conventional radiography and clinical findings to determine whether sonography can be a primary technique for evaluating nasal fracture in children. ⋯ Sonography can be a primary diagnostic technique for evaluating nasal fracture in children. It inflicts no radiation, provides various imaging planes without positional change, and can be used to evaluate the cartilaginous septum. Potential pitfalls are the nasofrontal suture, the junction between the nasal bone and the pyriform aperture of the maxilla, the vascular groove, and the presence of an old fracture. CT can be used in addition to sonography in cases of suspected complex facial bone trauma.

Controlled Clinical TrialAccuracy of transthoracic sonography in detection of pneumothorax after sonographically guided lung biopsy: prospective comparison with chest radiography.
The purpose of this study was to prospectively evaluate the accuracy of transthoracic sonography in the detection of pneumothorax after transthoracic sonographically guided lung biopsy. ⋯ These preliminary results suggest that transthoracic sonography is as effective as chest radiography in the detection of pneumothorax after transthoracic sonographically guided lung biopsy and may become the method of choice for excluding, diagnosing, and monitoring pneumothorax after transthoracic sonographically guided biopsy. Chest radiography may be needed only for assessment of the extent of pulmonary collapse after transthoracic sonographic diagnosis of pneumothorax or in the presence of discrepancy between transthoracic sonographic findings and clinical presentation.

Peripheral tear of the triangular fibrocartilage: depiction with MR arthrography of the distal radioulnar joint.
Although central tears of the triangular fibrocartilage are easily seen on imaging, peripheral tears of the ulnar attachment are frequently missed. The aim of this study was to evaluate the accuracy of MR arthrography of the distal radioulnar joint in depiction of peripheral tears of the triangular fibrocartilage. ⋯ MR arthrography of the distal radioulnar joint is accurate in depiction of peripheral tears of the ulnar attachment of the triangular fibrocartilage. These tears often appear as noncommunicating tears extending from the distal radioulnar joint into the triangular fibrocartilage.

ECG-gated 64-MDCT angiography in the differential diagnosis of acute chest pain.
The most important differential diagnoses of acute chest pain include myocardial infarction, aortic dissection, and pulmonary embolism. The purpose of this study was to evaluate the diagnostic value of an ECG-gated 64-MDCT angiography protocol for simultaneous assessment of the pulmonary arteries, coronary arteries, and aorta within a single breath-hold. ⋯ With current techniques, ECG-gated CT angiography of the entire chest has very good image quality. The protocol proved helpful in the differential diagnosis of acute chest pain.
