Functional Imaging: CT and MRI

SYNOPSIS: Numerous imaging techniques permit evaluation of regional pulmonary function. Contrast-enhanced CT methods now allow assessment of vasculature and lung perfusion. Techniques using spirometric controlled MDCT allow for quantification of presence and distribution of parenchymal and airway pathology, Xenon gas can be employed to assess regional ventilation of the lungs and rapid bolus injections of iodinated contrast agent can provide quantitative measure of regional parenchymal perfusion. Advances in magnetic resonance imaging (MRI) of the lung include gadolinium-enhanced perfusion imaging and hyperpolarized helium imaging, which can allow imaging of pulmonary ventilation and .measurement of the size of emphysematous spaces

Global Outreach Plan for Colleges

Dr. David J. Skorton, president of Cornell University, first introduced the idea of a new initiative emphasizing the international development of human capacity through the dissemination of university research, teaching and outreach at his first commencement address to the graduating class of 2007. Since then, the idea has inspired several conversations between Dr. Skorton and other academic leaders and institutions looking to effect change, including the U.S. Agency for International Development (USAID) and the National Association of State Universities and Land-Grant Colleges. He is also participating in the upcoming Higher Education Summit for Global Development with Secretary of State Condoleezza Rice, Secretary of Education Margaret Spellings and Administrator for USAID Henrietta Fore, the goal of which is to develop strategies to establish new and enduring higher education relationships for international development. These conversations help to galvanize the issue of eradicating international socioeconomic inequalities.</jats:p
