An 8-F 24-cm-long apheresis catheter was placed in the basilic vein with imaging-guided percutaneous technique in 15 children undergoing leukapheresis for collection of autologous peripheral blood stem cells. There were no immediate or long-term complications. This is a low-morbidity procedure requiring minimal sedation that results in successful collection of peripheral blood stem cells and allows flow rates comparable to those with surgically placed central catheters.

History of head and neck radiology: past, present, and future.
Head and neck radiology has evolved during the century since the discovery of the x ray in 1895 by Wilhelm Conrad Roentgen. In the first few decades, conventional radiography was the diagnostic modality for evaluation of head and neck diseases. Special radiographic projections were designed to demonstrate abnormal processes in the paranasal sinuses, temporal bones, base of the skull, and neck. ⋯ Computed tomography in 1972 and magnetic resonance imaging in 1982 improved our diagnostic capabilities by enabling location and characterization of tumors, cysts, and inflammatory processes in the head and neck and aiding in earlier diagnosis and treatment. Teaching of residents and fellows by an expanding staff of head and neck radiologists developed. The formation of the American Society of Head and Neck Radiology in 1977 provided a forum for postgraduate education and scientific exchange.

To develop a noninvasive method for intracranial elastance and intracranial pressure (ICP) measurement. ⋯ MR imaging-derived elastance index correlates with ICP over a wide range of ICP values. The sensitivity of the technique allows differentiation between normal and elevated ICP.

The communication between radiologists and their surgical colleagues is particularly important in the setting of back pain. This common disorder often does not have a definable cause, even when the imaging findings are abnormal. ⋯ Unfortunately, little standardization in the terminology for and management of back pain syndromes exists. This article elucidates the approaches to problems of back pain used in one clinical setting.
