MRSI may be just the "tool" to diagnose bipolar disorder
CHICAGO - Patients with bipolar disorder are often undiagnosed or misdiagnosed for years. But preliminary research suggests that magnetic resonance spectroscopy imaging (MRSI) may take the guesswork and delay out of diagnosis, according to Dr. John D. Port, Ph.D., assistant professor of radiology at the Mayo Clinic in Rochester, MN.

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.

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).
