99

The decay product of the medical isotope molybdenum-99 (Mo-99), technetium-99m (Tc-99m), and associated medical isotopes iodine-131 (I-131) and xenon-133 (Xe-133) are used worldwide for medical diagnostic imaging or therapy. The United States consumes about half of the world's supply of Mo-99, but there has been no domestic (i.e., U.S.-based) production of this isotope since the late 1980s. The United States imports Mo-99 for domestic use from Australia, Canada, Europe, and South Africa. Mo-99 and Tc-99m cannot be stockpiled for use because of their short half-lives. Consequently, they must be routinely produced and delivered to medical imaging centers. Almost all Mo-99 for medical use is produced by irradiating highly enriched uranium (HEU) targets in research reactors, several of which are over 50 years old and are approaching the end of their operating lives. Unanticipated and extended shutdowns of some of these old reactors have resulted in severe Mo-99 supply shortages in the United States and other countries. Some of these shortages have disrupted the delivery of medical care. Molybdenum-99 for Medical Imaging examines the production and utilization of Mo-99 and associated medical isotopes, and provides recommendations for medical use.

Participants of the July 17-18, 2017, symposium titled Opportunities and Approaches for Supplying Molybdenum-99 and Associated Medical Isotopes to Global Markets examined current trends in molybdenum-99 production, prospects for new global supplies, and technical, economic, regulatory, and other considerations for supplying molybdenum-99 to global markets. This publication summarizes the presentations and discussions from the symposium.

This book constitutes the refereed proceedings of the Second International Conference on Medical Image Computing and Computer-Assisted Intervention, MICCAI'99, held in Cambridge, UK, in September 1999. The 133 revised full papers presented were carefully reviewed and selected from a total of 213 full-length papers submitted. The book is divided into topical sections on data-driven segmentation, segmentation using structural models, image processing and feature detection, surfaces and shape, measurement and interpretation, spatiotemporal and diffusion tensor analysis, registration and fusion, visualization, image-guided intervention, robotic systems, and biomechanics and simulation.

The 99 Day Challenge provides a step-by-step program guided journal and the fundamental lessons of self-mastery that will help you to achieve anything from diets, fitness challenges, new entrepreneur goals and reach your true purpose. Dennis van der Heijden shows you how to take control of your life using scientifically proven effective strategies and techniques for mastering your goals, perspective on life, your body, your relationships and your life with gratitude. The guided journal is a daily checklist, with the aim to spend a couple of minutes every morning and a couple of minutes every evening reflexing on what you want to achieve and move your project or goal forward in micro-steps. Daily triggers split over 99 days with your improvements of today, suggestions for meditation, acts of kindness, exercise and gratitude.

In a bridge-building exercise between Christians, Muslims, and other people of the book, David Bentley traces the Semitic pre-Islamic origins of Islam s 99 names of God. He points the reader to Old Testament counterparts of these names as well as to Jesus comparable representations of Himself."
