MRI traces multisystem Fabry's disease in the brain, heart, and beyond
By Shalmali Pal
Fabry's disease is an inherited, gender-linked disorder caused by a deficiency of alpha-galactosidase A in the tissues and fluids. Renal, cardiac, and cerebrovascular complications can predispose patients with Fabry's disease to an untimely death in comparison to the general population. In the brain and the heart, MRI can track Fabry's disease patterns, giving physicians important information for therapy control.

Food for thought: Neuroimaging offers clues into eating-related psychopathology
By Shalmali Pal
In honor of National Eating Disorders Awareness Week, AuntMinnie.com surveyed the latest research in eating-related imaging using functional MRI (fMRI). The European and U.S. studies examined appetite-related brain activity, the subjective quality of appetite, and cerebral processing of food-related stimuli by gender, as well as hunger and satiety in anorexia patients.

CT spot sign predicts hematoma expansion in stroke patients
By Eric Barnes
In patients with intracerebral hemorrhage (ICH), hematoma expansion in the first critical hours after symptom onset is associated with significantly poorer outcomes. Thanks to CT imaging and a new drug in the pipeline, it may be possible to identify and treat ICH patients at risk of hematoma expansion while there is time to improve outcomes, according to two new studies.

ASPECTS stroke scoring improved with perfusion CT
By Eric Barnes
The Alberta Stroke Program Early CT Score (ASPECTS) rates the presence or absence of ischemia in 10 regions of the brain. Paired with noncontrast CT when a patient presents with stroke symptoms, ASPECTS has been shown to effectively predict which patients will benefit from thrombolytic therapy. A recent study using perfusion CT has found that ASPECT increases the accuracy for predicting radiological and clinical outcomes over noncontrast CT.

Relative threshold method correlates CT, MRI stroke infarct assessment
By Eric Barnes
SAN FRANCISCO - Researchers at the 2007 International Stroke Conference are making progress toward standardizing imaging and clinical criteria for the optimal treatment of stroke patients. The preliminary results from a study by Boston researchers are good news for CT perfusion imaging, which is faster and generally more available than MRI to handle emergent stroke cases.

Advanced MR clarifies nexus between white matter and cerebrovascular disease
By Shalmali Pal
SAN FRANCISCO - MRI has been a great boon to stroke researchers who are probing the depths of white matter and the reasons for its dysfunction. Unfortunately, standard MR has its limits in this beautiful and complex structure. But recent advances in MR technology should unlock some of the mystery surrounding white matter, according to a presentation at the 2007 International Stroke Conference.

MRI should be preferred test for suspected acute stroke
By Shalmali Pal
MRI should replace CT as the first-line test for accurate diagnosis of suspected acute stroke, according to a study published today in the Lancet. The authors found that MRI was superior to CT for diagnosing ischemic stroke, as well as acute and chronic hemorrhage. While cost is an issue with MRI, its greater diagnostic accuracy would justify the extra expense, they said.
