Interpretation of chest radiographs in infants with cough and fever.

An understanding of the appearance of the infant chest radiograph requires an understanding of the anatomy and the physiologic, immunologic, and pathologic processes in the infant's chest. The authors describe the features of the infant chest that most influence the appearance of the chest radiograph in infants with cough and fever. They discuss why confusion sometimes occurs when radiology residents and general radiologists familiar with adult chest radiographs first evaluate the infant chest radiograph. The radiographic appearance of acute inflammation does not look the same in infants as it does in older children and adults. The hallmark of inflammatory lung disease in the infant chest is air trapping on the chest radiograph.

Overcoming obstacles to work-changing technology such as PACS and voice recognition.

OBJECTIVE: When implementing picture archival communication systems (PACS) and voice recognition (VR) technology in radiology, management attention generally has focused on justifying the system financially, investigating potential vendors, developing timelines for hardware delivery, installing the software, developing interfaces, and tracking and measuring results. These are critical components in implementing PACS and VR technology, but not sufficient for success. CONCLUSION: This article argues that the ability to view organizational issues related to changing how people do their work from multiple organizational perspectives is equally important in determining the success of PACS and VR projects.
