Comparative StudyColor Doppler sonography in early renal transplantation follow-up: resistive index measurements versus power Doppler sonography.
This study was designed to compare power Doppler images of perfusion with interlobar resistive index measurements obtained during the early monitoring of renal graft transplant to diagnose cortical perfusion abnormalities and assess prognosis. ⋯ This study suggests that color Doppler sonography is insensitive in revealing and in allowing radiologists to differentiate the causes of graft dysfunction. However, power Doppler sonography allows a prediction of the functional recovery of the graft at 12 months after transplantation not provided by resistive index levels.

Our purpose was to describe the CT findings in patients with Bezold's abscesses. ⋯ Bezold's abscesses are rare complications of mastoiditis. In our series most were seen in adults and were associated with a history of cholesteatoma and mastoidectomy. CT of the neck and temporal bone can help the surgeon determine appropriate treatment.

Anatomy of the normal brachial plexus revealed by sonography and the role of sonographic guidance in anesthesia of the brachial plexus.
The purpose of this study is to describe the sonographic appearance of the normal brachial plexus and to evaluate the use of imaging guidance for brachial plexus anesthesia. ⋯ High-resolution sonography can show normal brachial plexus anatomy and facilitate catheter-based brachial plexus anesthesia without complications.

Nonspecific interstitial pneumonia with fibrosis: high-resolution CT and pathologic findings.
The purpose of our study was to describe high-resolution CT findings of nonspecific interstitial pneumonia with fibrosis and to compare findings seen on CT with pathologic findings. ⋯ On high-resolution CT, nonspecific interstitial pneumonia with fibrosis is most commonly revealed as patchy subpleural areas of ground-glass opacity mixed with irregular linear opacity or bronchial dilatation. These areas represent interstitial thickening caused by varying degrees of interstitial inflammation, fibrosis, or both.
