Quantification Of Perfusion & Permeability In Prostate Using Dynamic Contrast-Enhanced MRI With Inversion-Prepared Dual-Contrast Sequence
UroToday.com - The dynamic contrast-enhanced dynamic susceptibility contrast magnetic resonance imaging (DCE-DSC-MRI) technique presented in the article(1) is based on a novel dual-contrast sequence. The sequence is a gradient echo sequence that uses a single inversion pulse and subsequent acquisition of two contrasts/echoes with different inversion and echo times. Inversion preparation increases the signal-to-noise ratio in comparison to other gradient echo sequences. The blood volume in the prostate is relatively small, i.e., approximately one percent, while the interstitial contrast-agent-enhancing volume is approximately 20 percent. Therefore, conventional imaging sequences fail to separate the low contrast agent signal originating from the blood from that originating from interstitial tissue. The first contrast/echo is acquired with a short echo time and is T1-weighted, allowing quantification of the total signal contribution while failing to separate the blood signal from the interstitial contrast agent signal.

A Selection Of Thursday's Editorials And Opinions

The GOP Can Stop ObamaCare Wall Street Journal Americans will listen more closely to Republicans if they make empirical and specific arguments against Mr. Obama"s attempted government takeover of the nation"s health system. But they must also offer proposals that families, small-businesspeople and health-care providers will applaud (Karl Rove, 6/18). Give GOP Proposal For Health Care Respectful Hearing Houston Chronicle Conventional wisdom has it that Democrats in this Age of Obama "own" health care as a political and, some would argue, a moral issue. But that hasn"t prevented congressional Republicans from coming up with their own plan for reform - nor should it (6/17). The Individual Mandate - An Affordable and Fair Approach to Achieving Universal Coverage New England Journal of Medicine The orientation of our system and the distorted incentives that it creates can be changed. A vital component of such a change would be bringing all U.S. residents into our health insurance system through an individual mandate (Linda Blumberg and John Holahan, 6/17). "Public Option": Son Of Medicaid Wall Street Journal It seems to me, if we"re honest, that one other contributor to the health-care morass should have been on the president"s list: Congress (Daniel Henninger, 6/18). Government Guidelines May Harm Health Care San Francisco Chronicle Although supported by some, the notion of guidelines has not won universal approval among practicing clinicians, who are apprehensive and suspicious that federal treatment protocols will bind medical practitioners to treat Medicare beneficiaries with particular ailments in a certain way or mandate justification for deviating from government-set standards (Sidney Marchasin, 6/18). Reform Needs To Improve Medicare Reimbursements The Buffalo News Paradoxically, while this region"s work force and employers contribute equally to the Medicare premium, they do not receive an average share of revenues. This has unintended consequences that need to be addressed by national health care reform (Dennis Horrigan, 6/17). Strategy Corner: Health Care Reform Done Right Politico The unions want universal coverage as a victory for their members and for them. They are pushing the administration to be tougher, and they can move a lot of members and money in a campaign to counter the industry. So Obama really has three basic strategies before him (Mark Penn, 6/18). This information was reprinted from kaiserhealthnews.org with kind permission from the Henry J. Kaiser Family Foundation.
