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.

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.

3-tesla MRI sheds light on shading sign in endometriosis
By Shalmali Pal
On T1-weighted MRI, endometrial cysts generally show high signal intensity. Unfortunately, so does other gynecological pathology. Differentiating endometrial cysts from other hemorrhage adnexal cysts is important for adequate treatment, according to Japanese researchers. They compared the MR manifestations of endometrial cysts using both 1.5- and 3-tesla MRI.

Obesity and prostate cancer: Should imaging have a role in screening?
By Kate Madden Yee
Prostate cancer remains a significant health concern in the U.S., where nearly 235,000 men were diagnosed with the disease last year. Preliminary research in obese men strongly suggests that these patients are susceptible to more aggressive cancers and higher mortality rates, and traditional prostate cancer screening exams are not always accurate in this population. Experts weigh in on whether screening obese patients with imaging would be a better bet.
