ISMRM welcomes radiologists to 21st-century radiology

May 12, 2008 ISMRM welcomes radiologists to 21st-century radiology James Brice -------------------------------------------------------------------------------- We are already eight years into the New Millennium. The Y2K crisis is a distant memory, and debate about whether the new century actually began in 2000 or 2001 is far behind us. Yet the fact that we somehow crossed a great divide back in '00 finally sank in during the 2008 International Society for Magnetic Resonance in Medicine meeting… Continue

Siemens casts Tim as its unifying thread

May 9, 2008 Siemens casts Tim as its unifying thread Greg Freiherr -------------------------------------------------------------------------------- Above and around the Siemens Healthcare booth at the ISMRM meeting, the message "pushing the boundaries of MR" was as clear as it could be. The theme was driven home by pennants featuring iconic reconstructions of athletes into whole-body 2D renditions of muscles and organs. How the company pushes these boundaries, however, had been more subtext… Continue

Report from ISMRM: Ultrahigh-field MRI improves characterization of multiple sclerosis

May 9, 2008 Report from ISMRM: Ultrahigh-field MRI improves characterization of multiple sclerosis James Brice -------------------------------------------------------------------------------- Diagnostic power and field strength go hand in hand when it comes to evaluating multiple sclerosis. It is no secret among board-certified radiologists that 1.5T MRI misses many MS-related white-matter lesions found during postmortem histology. It is unable to characterize much gray matter pathology at all.… Continue

Radiologist finds potential in FIESTA for noncontrast renal artery MRA

May 9, 2008 Radiologist finds potential in FIESTA for noncontrast renal artery MRA James Brice -------------------------------------------------------------------------------- A noncontrast, flow-dependent FIESTA sequence offers a safe and effective alternative to gadolinium-enhanced MR angiography for renal artery evaluations. That conclusion, drawn from a Japanese study of 63 patients with suspected renal tumors, should come as good news to physicians who are making treatment decisions for… Continue

Functional brain mapping boosts early assessment of brain cancer treatment response

May 9, 2008 Functional brain mapping boosts early assessment of brain cancer treatment response James Brice -------------------------------------------------------------------------------- The first three months after standard radiation therapy for a brain tumor must be hell for patients and their families. The established MacDonald criteria for assessing treatment force them to wait up to 10 weeks for follow-up CT or MR to determine if the size of the treated tumor has changed. Using the… Continue

Report from ISMRM: MRS glutamate measures reflect heroin craving

May 8, 2008 Report from ISMRM: MRS glutamate measures reflect heroin craving James Brice -------------------------------------------------------------------------------- New MR spectroscopy findings indicate that changes in brain glutamate levels reflect changes in heroin craving among addicts during methadone maintenance therapy. MRS may eventually help predict if addicts will relapse after treatment. Animal studies have previously shown that glutamate is involved in the development and… Continue
