Noncathartic bowel prep facilitates, complicates virtual colonoscopy
By Eric Barnes
SAN FRANCISCO - Studies suggest that virtual colonoscopy without cathartic bowel preparation is feasible and sufficiently accurate. More patients might be willing to get screened. But if prepless VC makes patients' lives easier, it complicates matters for radiologists. Dr. Michael Zalis from Massachusetts General Hospital in Boston discussed several issues that impact the emergence of a kinder, gentler screening exam at the International Symposium on Multidetector-Row CT.

First PET/MRI brain images debut at SNM 2007
By Wayne Forrest
Physicians and radiologists may have another hybrid imaging technology to delve deeper into the burgeoning realm of molecular imaging and investigate neurological studies, as well as certain forms of cancer, stroke, and stem cell therapy. Researchers from Germany and the U.S. unveiled the world's first human brain images from a work-in-progress PET/MRI system at the 2007 SNM meeting last week in Washington, DC.

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.

Lower tube voltage leads to reduced dose in pediatric CT
By Brian Casey
SAN FRANCISCO - Radiation dose can be reduced in pediatric CT imaging without compromising image quality by using lower tube voltages, according to CT pioneer Willi Kalender, Ph.D. Dose could potentially be reduced even further if manufacturers tweaked their systems to enable them to scan at lower energies than those commonly used now, he said at yesterday's sessions of Stanford University's International Symposium on Multidetector-Row CT.

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.
