Telemedicine and teleradiology.

Inherent challenges accompany the rapidly increasing use of teleradiology and other telemedicine applications. These challenges include the complex interaction of multiple technologies as well as new operational procedures and changes in the way health care is delivered. This article focuses on the operational issues surrounding telemedicine, teleradiology and the transition to a digital department. The legal implications of telemedicine and government's role in regulating it are emphasized, along with telemedicine's impact on rural health care.

Principles of cardiac catheterization.

Cardiac catheterization, the insertion of catheters into the heart to measure pressures, obtain images and facilitate treatment, is a relatively new procedure and has evolved quickly into a critical diagnostic and therapeutic tool. This article discusses the history of cardiac catheterization, indications and contraindications for its use, catheterization equipment and procedures, patient follow-up and possible complications.

Benign breast disease.

When faced with a suspicious clinical or mammographic finding, patients may be anxious about the possibility of breast cancer. Because many of these findings are benign, clinicians attempt to make a rapid and accurate diagnosis to definitively rule out carcinoma. Imaging plays a key role in diagnostic strategies. This article addresses some of the more common benign breast diseases and their differential diagnosis from malignant breast disease.

Pediatric skeletal trauma.

Children with traumatic injuries present an emotionally and professionally demanding situation for radiologic technologists. A child's fear and anxiety, developmental stage and the psychological impact on parents and caregivers all affect the technologist's ability to perform a rapid but technically excellent exam. This article examines the specific causes and presentations of unintentional (as opposed to abuse-related) skeletal trauma in children, with emphasis on the role of imaging. The differences between children and adults in terms of injury patterns, healing and complications are discussed, along with efforts to reduce the incidence of childhood skeletal trauma.
