Functional MRI: Advancing clinical opportunities for neuroradiology
Functional MRI has provided fascinating insights into how the brain functions. It offers potential applications that have yet to be discovered. And radiologists can expand the clinical opportunities available to them by integrating fMRI into the services they offer, according to Dr. Catherine Elsinger of clinical research service company Neurognostics.

Delayed PET helps delineate gliomas
By Jonathan S. Batchelor
Differentiating high-grade gliomas from gray-matter structures with F-18 FDG-PET has been problematic for clinicians because of the brain's avidity for the radiotracer. A recent study from the University of Washington School of Medicine in Seattle presents evidence that extending the interval between FDG administration and PET data acquisition improves the delineation of gliomas from gray matter.

Neurognostics sees business potential in fMRI
By Brian Casey
Functional MRI is one of the most exciting areas of medical imaging -- an imaging technique that provides a window into the intricate relationship between higher consciousness and the biochemical processes that govern mind and body. But is it exciting enough to base an entire company on it? The folks at Neurognostics are doing just that.

Beyond CT: Diagnosing the unusual stroke
By Eric Barnes
SAN FRANCISCO - In the fevered race to diagnose patients with vague neurological symptoms, emergency doctors must keep an eye out for unusual stroke types that can require different imaging exams or treatment approaches, according to Dr. E. Bradshaw Bunney, who spoke at the American College of Emergency Physicians annual meeting on Tuesday.

Real-time CT teamed with tracer tracks CED treatment
By Shalmali Pal
SAN FRANCISCO - The latest oncologic technique for treating tumors involves convention-enhanced delivery (CED). But determining whether CED was successful requires the development of imaging tracers for real-time, in-vivo monitoring, according to a presenter Monday at the Congress of Neurological Surgeons (CNS).

SPECT shows promise in diagnosing Parkinson's
By Jonathan S. Batchelor
Clinical evaluation is the standard by which Parkinson's disease (PD) and parkinsonian syndrome (PS) are currently diagnosed. But a new study suggests that functional SPECT neuroimaging with the radiotracer (123I) ß-carboxymethoxy-3-ß-(4-iodophenyl) tropane (CIT) might do a better job, detecting those patients who are thought to have PS, but turn out negative at follow-up.

Changing market for PET brings challenges and opportunities
PET is moving into the frontline of imaging, and its procedure volume is continuing to grow due to increased applications, accessibility, and recognition. And although prices will diminish, the growing markets will more than offset pricing reductions. In the end, both manufacturers and patients will benefit, according to Marvin Burns, president of market research firm Bio-Tech Systems.
