Just say 'eee' for neck CT
By Eric Barnes
For maximizing airflow and air contrast, having patients hold their breath and form an "eee" with their mouths during MDCT acquisition really opens up the airways, optimizing the visualization of mucosa while imaging the larynx, pharynx, and the rest of the neck, according to researchers from Vanderbilt University in Nashville, TN.

HARM makes good on poststroke MR, exposes blood-brain barrier disruption
By Shalmali Pal
When stroke patients undergo standard FLAIR MR imaging, delayed gadolinium enhancement in the cerebral spinal fluid space -- or what researchers at the National Institute of Neurological Disorders and Stroke are calling hyperintense acute reperfusion marker (HARM) -- may indicate early blood-brain barrier disruption, reperfusion injury, hemorrhagic transformation, and poor clinical outcome. HARM also could help broaden the therapeutic window for stroke patients.

Diffusion-weighted MRI: The cornerstone of neuroimaging-based stroke studies
By Shalmali Pal
A multitude of new studies published in the journal Stroke examine the increasing validity of MR in stroke imaging. The technique discussed in two papers is the diffusion-perfusion mismatch model with the goal of devising a "simple and practical means" of pinpointing the ischemic penumbra and identifying patients who are more likely to respond to reperfusion therapy. In the third, DWI results are used to create an outcome prediction model.

3D surface-rendered facial images a poor substitute for digital photos
By Erik L. Ridley
PROVIDENCE, RI - Creating detailed pictures of the face from 3D surface-reconstructed images could be construed as a patient privacy issue under the provisions of the Health Insurance Portability and Accountability Act (HIPAA). But the ability to identify patients from their 3D facial images is still relatively low, according to a study presented at this week's Society for Imaging Informatics in Medicine (SIIM) meeting.

256-slice CT brings new possibilities in head imaging
By Eric Barnes
Researchers in Japan and the U.S. are producing promising new head CT images on a work-in-progress 256-slice scanner. A major advantage of so-called area detector scanning is the ability to acquire morphologic and functional images in a single scan, yielding a clutch of new diagnostic possibilities and time-saving exam protocols.

Presurgical fMRI for tumor resection: Are we there yet?
By Shalmali Pal
BERLIN - In theory, functional MRI offers the ultimate noninvasive, presurgical management tool for brain tumor resection. In practice, fMRI techniques have a way to go before they can be as accurate as intraoperative cortical stimulation (ICS), according to Dr. Stefan Sunaert, Ph.D., from the University Hospital of the Catholic University of Leuven in Belgium. Sunaert discussed some of the strengths and weaknesses of fMRI for brain tumor mapping in a talk Sunday at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.
