There have been remarkable achievements in CT technology, workflow management and applications in the last couple of years. The introduction of 4- and 16-row multidetector technology has substantially increased acquisition speed and provides nearly isotropic resolution. These new technical possibilities had significant impact on the clinical use of CT and have yielded a broadening of the spectrum of applications, particularly in vascular, cardiac, abdominal, and trauma imaging.

This book presents the practical experience of an international expert group of radiologists and physicists with state-of-the-art multidetector technology. The chapters in this book will facilitate a thorough understanding of 4- and 16-slice multidetector-row CT and its clinical applications. This will help to fully exploit the diagnostic potential of this technology.

Until recently, CT scanner performance was limited by a series of compromises. With single-detector scanners, one cannot select thin collimation and still maintain the required extent of volumetric coverage. Slow scans cause motion artifacts that impair image quality. The introduction of multidetector CT technology, however, has revolutionized the field. Currently multidetector, multislice CT scanners acquire up to four channels of data from interweaving spirals. The minimum gantry rotation period is as low as half of a second. This increased scan speed allows for thinner collimation and thus higher longitudinal or z-axis resolution in comparison with single-detector CT. The improved image quality with multidetector technology leads to new applications of CT, particularly in cardiac, vascular, and abdominal imaging. On-going clinical studies are evaluating the suitability of this new imaging tool for non-invasive screening and diagnosis of coronary artery disease. A particular advantage to the increased scan speed in vascular imaging is the ability to cut intra venous contrast dosage and still maintain peak enhancement CT throughout the entire acquisition. Thin-section, multiphasic acquisition during optimal arterial-phase and venous-phase enhan cement significantly improves the accuracy for small lesion and vessel detection, and enhances overall classification of abdominal neoplasms. On the other hand, the increasingly large volume data sets force to new ways of looking at, presenting, storing, and trans ferring images. Networking and two- and three dimensional data processing are the key words."

Seeks to determine what methods or organization should be established to integrate the results of private, industrial, foundational and university research and development work into the Army technical program and functioning. Determines Army should continue the present organization and policy for integration of civilian research activities into those of the Army Technical Services.

William A. Read (1869-1962) was an internationally educated and renowned linguist whose career included 38 years as a professor of English at Louisiana State University. His writings spanned five decades and have been instrumental across a wide range of academic disciplines. Most importantly, Read devoted a good portion of his research to the meaning of place names in the southeastern United States - especially as they related to Indian word adoption by Europeans.This volume includes his three Louisiana articles combined: ""Louisiana Place-Names of Indian Origin"" (1927), ""More Indian Place-Names in Louisiana"" (1928), and ""Indian Words"" (1931). Joining Alabama's reprint of ""Indian Place Names in Alabama"" and ""Florida Place Names of Indian Origin"" and ""Seminole Personal Names"", this volume completes the republication of the southern place name writings of William A. Read.
